Changelog
| This page is no longer maintained. Please go to the new one. |
0.75 (2015-01-15)
-----------------
- Fixed issue with teletext to other then srt.
- CCExtractor can be used as library if compiled using cmake
- By default the Windows version adds BOM to generated UTF files (this is
because it's needed to open the files correctly) while all other
builds don't add it (because it messes with text processing tools).
You can use -bom and -nobom to change the behaviour.
0.74 (2014-09-24)
-----------------
- Fixed issue with -o1 -o2 and -12 parameters (where it would write output only in the o2 file)
- Fixed UCLA parameter issue. Now the UCLA parameter settings can't be overwritten anymore by later parameters that affect the custom transcript
- Switched order around for TLT and TT page number in custom transcript to match UCLA settings
- Added nobom parameter, for when files are processed by tools that can't handle the BOM. If using this, files might be not readable under windows.
- Segfault fix when no input files were given
- No more bin output when sending to server + possibility to send TT to server for processing
- Windows: Added the Microsoft redistributable MSVCR120.DLL to both the installation package and the application zip.
0.73 - GSOC (2014-08-19)
------------------------
- Added support of BIN format for Teletext
- Added start of librarisation. This will allow in the future for other programs to use encoder/decoder functions and more.
0.72 - GSOC (2014-08-12)
------------------------
- Fix for WTV files with incorrect timing
- Added support for fps change using data from AVC video track in a H264 TS file.
- Added FFMpeg Support to enable all encapsulator and decoder provided by ffmpeg
0.71 - GSOC (2014-07-31)
------------------------
- Added feature to receive captions in BIN format according to CCExtractor's own
protocol over TCP (-tcp port [-tcppassword password])
- Added ability to send captions to the server described above or to the
online repository (-sendto host[:port])
- Added -stdin parameter for reading input stream from standard input
- Compilation in Cygwin using linux/Makefile
- Fix for .bin files when not using latin1 charset
- Correction of mp4 timing, when one timestamp points timing of two atom
0.70 - GSOC (2014-07-06)
------------------------
This is the first release that is part of Google's Summer of Code.
Anshul, Ruslan and Willem joined CCExtractor to work on a number of things
over the summer, and their work is already reaching the mainstream
version of CCExtractor.
- Added a huge dictionary submitted by Matt Stockard.
- Added DVB subtitles decoder, spupng in output
- Added support for cdt2 media atoms in QT video files. Now multiple atoms in
a single sample sequence are supported.
- Changed Makefile.
- Fixed some bugs.
- Added feature to print info about file's subtitles and streams (-out=report).
- Support Long PMT.
- Support Configuration file.
- There is an sample configuration file in doc/ folder with name
ccextractor.cnf.sample
- Just now only ccextractor.cnf named files kept beside ccextractor
executable is supported
- for details of which options can be set using configuration file,
please look at sample file.
- Added options for custom transcript output:
new parameter (-customtxt format), where the format must be like this: 1100100 (7 digits).
These indicate whether the next things should be displayed or not in the (timed) transcript:
- Display start time
- Display end time
- Display caption mode
- Display caption channel
- Use a relative timestamp ( relative to the sample)
- Display XDS info
- Use colors
Examples:
0000101 is the default setting for transcripts
1110101 is the default for timed transcripts
1111001 is the default setting for -ucla
Make sure you use this parameter after others that might affect these
settings (-out, -ucla, -xds, -txt, -ttxt, ...)
- Fixed Negative timing Bug
0.69 (2014-04-05)
-----------------
- A few patches from Christopher Small, including proper support
for multiple multicast clients listening on the same port.
- GUI: Fixed teletext preview.
- GUI: Added a small indicator of data being received when reading from
UDP.
- GUI: Added UTF-8 support to preview Window (used for teletext).
- Fixes in Makefile and build script, compilation in linux and OSX failed
if another libpng was found in the system.
- WTV support directly in CCExtractor (no need for wtvccdump any more).
- Started refactoring and clean-up.
- Fix: MPEG clock rollover (happens each 26 hours) caused a time
discontinuity.
- Windows GUI: Started work on HDHomeRun support. For now it just looks
for HDHomeRun devices. Lots of other things will arrive in the next
versions.
- Windows GUI: Some code refactoring, since the HDHomeRun support makes
the code larger enough to require more than one source file :-)
0.68 (2013-12-24)
-----------------
- A couple of shared variables between 608 decoders were causing
problems when both fields were processed at the same time with
-12, fixed.
- Added BOM for UTF-8 files.
- Corrected a few extended characters in the UTF-8 encoding,
probably never used in real world captioning but since we got
a good test sample file...
- Color and fonts in PAC commands were ignored, fixed (Helen Buus).
- Added a new output format, spupng. It consists on one .png file
for each subtitle frame and one .xml with all the timing
(Heleen Buus).
- Some fixes (Chris Small).
0.67 (2013-10-09)
-----------------
- Padding bytes were being discarded early in the process in 0.66,
which is convenient for debugging, but it messes with timing in
.raw, which depends on padding. Fixed.
- MythTV's branch had a fixed size buffer that could not be enough
some times. Made dynamic.
- Better support for PAT changing mid stream.
- Removed quotes in Start in .smi (format fix).
- Added multicast support (Chris Small)
- Added ability to select IP address to bind in UDP (Chris Small)
- Fixes in -unixts and -delay for teletext.
- Added -autodash : When two people are talking, add a dash as
needed (this is based on subtitle position). Only in .srt and
with -trim. Quite experimental, feedback appreciated.
- Added -latin1 to select Latin 1 as encoding. Default is now
UTF-8 (-utf8 still exists but it's not needed).
- Added -ru1, which emulates a (non-existing in real life) 1 line
roll-up mode.
0.66 (2013-07-01)
-----------------
- Fixed bug in auto detection code that triggered a message
about file being auto of sync.
- Added -investigate_packets
The PMT is used to select the most promising elementary stream
to get captions from. Sometimes captions are where you least
expect it so -datapid allows you to select a elementary stream
manually, in case the CC location is not obvious from the PMT
contents. To assist looking for the right stream, the parameter
"-investigate_packets" will have CCExtractor look inside each
stream, looking for CC markers, and report the streams that
are likely to contain CC data even if it can't be determined from
their PMT entry.
- Added -datastreamtype to manually selecting a stream based on
its type instead of its PID. Useful if your recording program
always hides the caption under the stream stream type.
- Added -streamtype so if an elementary stream is selected manually
for processing the streamtype can be selected too. This can be
needed if you process for example a stream that is declared as
"private MPEG" in the PMT, so CCExtractor can't tell what it is.
Usually you'll want -streamtype 2 (MPEG video) or -streamtype 6
(MPEG private data).
- PMT content listing improved, it now shows the stream type for
more types.
- Fixes in roll-up, cursor was being moved to column 1 if a
RU2, RU3 or RU4 was received even if already in roll-up mode.
- Added -autoprogram. If a multiprogram TS is processed and
-autoprogram is used CCExtractor will analyze all PMTs and use
the first program that has a suitable data stream.
- Timed transcript (ttxt) now also exports the caption mode
(roll-up, paint-on, etc) next to each line, as it's useful to
detect things like commercials.
- Content Advisory information from XDS is now decoded if it's
transmitted in "US TV parental guidelines" or "MPA".
Other encoding such as Canada's are not supported yet due
to lack of samples.
- Copy Management information from XDS is now decoded.
- Added -xds. If present and export format is timed transcript
(only), XDS information will be saved to file (same file as the
transcript, with XDS being clearly marked). Note that for now
all XDS data is exported even if it doesn't change, so the
transcript file will be significantly larger.
- Added some PaintOn support, at least enough to prevent it
from breaking things when the other modes are used.
- Removed afd_data() warning. AFD doesn't carry any caption related
data. AFD still detected in code in case we want to do something
with it later anyway.
- Ported last changes from Petr Kutalek's telxcc. Current version
is 2.4.4.
- In teletext mode when exporting to transcript (not .srt), an effort
is made to detect and merge line duplicates. This is done by using
the Levenshtein's distance, which is the number of changes requires
to convert one string to another. To simplify things, strings are
compared up to the length of the shortest one.
There are 3 parameters that can be used to tweak the thresholds:
-deblev: Enable debug so the calculated distance for each two
strings is displayed. The output includes both strings, the
calculated distance, the maximum allowed distance, and whether
the strings are ultimately considered equivalent or not, i.e.
the calculated distance is less or equal than the max allowed.
-levdistmincnt value: Minimum distance we always allow
regardless of the length of the strings. Default 2. This means
that if the calculated distance is 0, 1 or 2, we consider the
strings to be equivalent.
-levdistmaxpct value: Maximum distance we allow, as a
percentage of the shortest string length. Default 10%. For
example, consider a comparison of one string of 30 characters
and one of 60 characters. We want to determine whether the
first 30 characters of the longer string are more or less the
same as the shortest string, i.e. whether the longest string
is the shortest one plus new characters and maybe some
corrections. Since the shortest string is 30 characters and
the default percentage is 10%, we would allow a distance of
up to 3 between the first 30 characters.
- Added -lf : Use UNIX line terminator (LF) instead of Windows (CRLF).
- Added -noautotimeref: Prevent UTC reference from being auto set from
the stream data.
0.65 (2013-03-14)
-----------------
- Minor GUI changes for teletext
- Added end timestamps in timed transcripts
- Added support for SMPTE (patch by John Kemp)
- Initial support for MPEG2 video tracks inside MP4 files (thanks a
lot to GPAC's Jean who assisted in analyzing the sample and
doing the required changes in GPAC).
- Improved MP4 auto detection
- Support for PCR if PTS is not available (needed for some teletext
samples, and probably useful for everything else).
- Support for UDP streaming - finally. Use "-udp $port" to have
CCExtractor listen for a stream. I've only been able to test it
with an European HDHomeRun, but it should work fine with any other
tuner.
- Refactored PMT / PAT processing in transport streams, now allows to
display their contents (-parsePAT and -parsePMT) which makes
troubleshooting easier.
0.64 (2012-10-29)
-----------------
- Changed Window GUI size (larger).
- Added Teletext options to GUI.
- Added -teletext to force teletext mode even if not detected
- Added -noteletext to disable teletext detection. This can be needed
for streams that have both 608 data and teletext packets if you
need to process the 608 data (if teletext is detected it will
take precedence otherwise).
- Added -datapid to force a specific elementary stream to be used for
data (bypassing detections).
- Added -ru2 and -ru3 to limit the number of visible lines in roll-up
captions (bypassing whatever the broadcast says).
- Added support for a .hex (hexadecimal) dump of data.
- Added support for wtv in Windows. This is done by using a new program
(wtvccdump.exe) and a new DirectShow filter (CCExtractorDump.dll) that
process the .wtv using DirecShow's filters and export the line 21 data
to a .hex file. The GUI calls wtvccdump.exe as needed.
- Added --nogoptime to force PTS timing even when CCExtractor would
use GOP timing otherwise.
0.63 (2012-08-17)
-----------------
- Telext support added, by integrating Petr Kutalek's telxcc. Integration is
still quite basic (there's equivalent code from both CCExtractor and
telxcc) and some clean up is needed, but it works. Petr has announced that
he's abandoning telxcc so further development will happen directly in
CCExtractor.
- Some bug fixes, as usual.
0.62 (2012-05-23)
-----------------
- Corrected Mac build "script" (needed to add GPAC includes). Thanks to the
Mac users that sent this.
- Hauppauge mode now uses PES timing, needed for files that don't have
caption data during all the video (such as in commercial breaks).
- Added -mp4 and -in:mp4 to force the input to be processed as MP4.
- CC608 data embedded in a separate stream (as opposed as in the video
stream itself) in MP4 files is now supported (not heavily tested).
This should be rather useful since closed captioned files from iTunes
use this format.
- More CEA-708 work. The debugger is now able to dump the "TV" contents for
the first time. Also, a .srt can be generated, however timing is not quite
good yet (still need to figure out why).
- Added -svc (or --service) to select the CEA-708 services to be processed.
For example, -svc 1,2 will process the primary and secondary language
services. Valid values are 1-63, where 1 is the primary language, 2 is
the secondary language (this is part of the specification) and 3-63 are
provider defined.
- Rajesh Hingorani sent a fix for the MPEG decoder that fixes garbled output
or certain samples (we had none like this in our test collection). Thanks,
Rajesh.
0.61 (2012-03-08)
-----------------
- Fix: GCC 3.4.4 can now build CCExtractor.
- Fix: Damaged TS packets (those that come with 'error in transport' bit
on) are now skipped.
- Fix: Part of the changes for MP4 support (CC packets buffering in
particular) broke some stuff for other files, causing at least very
annoying character duplication. We hope we've fixed it without breaking
anything but please report).
- Some non-interesting cleanup.
0.60 (unreleased)
-----------------
- Add: MP4 support, using GPAC (a media library). Integration is currently
"enough so it works", but needs some more work. There's some duplicate
code, the stream must be a file (no streaming), etc.
- Fix: The Windows version was writing text files with double \r.
- Fix: Closed captions blocks with no data could cause a crash.
- Fix: -noru (to generate files without duplicate lines in
roll-up) was broken, with complete lines being missing.
- Fix: bin format not working as input.
0.59 (2011-10-07)
-----------------
- More AVC/H.264 work. pic_order_cnt_type != 0 will be processed now.
- Fix: Roll-up captions with interruptions for Text (with ResumeTextDisplay
in the middle of the caption data) were missing complete lines.
- Added a timed text transcript output format, probably only useful for
roll-up captions. Use --timedtranscript or -ttxt. Output is like this:
00:01:25,485 | HOST: LAST NIGHT THE REPUBLICAN
00:01:29,522 | HOPEFULS INTRODUCE THEMSELVES TO
00:01:30,623 | PRIMARY VOTERS.
- XDS parser. Not complete (no point in dealing with V-Chip stuff for
example), but enough to extract program and station information.
- Input streams can now come from standard input using - (just an hyphen)
as parameter.
- Added a new output format called 'null' (use -null or -out=null). This
format means "Don't produce any file", and is useful to have CCExtractor
process the stream (for XDS messages, debugging, etc) without actually
generating anything.
- Updated Windows GUI.
- Added -quiet => If used, CCExtractor will not write any message.
- Added -stdout => If used, the captions will be sent to stdout (console)
instead of file. Combined with -, CCExtractor can work as a filter in
a larger process, receiving the stream from stdin and sending the
captions to stdout.
- Some code clean up, minor refactoring.
- Teletext detection (not yet processing).
0.58 (2011-08-21)
-----------------
- Implemented new PTS based mode to order the caption information
of AVC/H.264 data streams. The old pic_order_cnt_lsb based method
is still available via the -poc or --usepicorder command switches.
- Removed a couple of those annoying "Impossible!" error messages
that appears when processing some (possibly broken, unsure) files.
- Added -nots --notypesettings to prevent italics and underline
codes from being displayed.
- Note to those not liking the paragraph symbol being used for the
music note: Submit a VALID replacement in latin-1.
- Added preliminary support for multiple program TS files. The
parameter --program-number (or -pn) will let you choose which
program number to process. If no number is passed and the TS
file contains more than one, CCExtractor will display a list of
found programs and terminate.
- Added support (basic, because I only received one sample) for some
Hauppauge cards that save CC data in their own format. Use the
parameter -haup to enable it (CCExtractor will display a notice
if it thinks that it's processing a Hauppauge capture anyway).
- Fixed bug in roll-up.
- More AVC work, now TS files from echostar that provided garbled
output are processed OK.
- Updated Windows GUI.
0.57 (2010-12-16)
-----------------
- Bugfixes in the Windows version. Some debug code was unintentionally
left in the released version.
0.56 (2010-12-09)
-----------------
- H264 support
- Other minor changes a lot less important
0.55 (2009-08-09)
-----------------
- Replace pattern matching code with improved parser for MPEG-2 elementary
streams.
- Fix parsing of ReplayTV 5000 captions.
- Add ability to decode SCTE 20 encoded captions.
- Make decoding of TS files more error tolerant.
- Start implementation of EIA-708 decoding (not active yet).
- Add -gt / --goptime switch to use GOP timing instead of PTS timing.
- Start implementation of AVC/H.264 decoding (not active yet).
- Fixed: The basic problem is that when 24fps movie film gets converted to 30fps NTSC
they repeat every 4th frame. Some pics have 3 fields of CC data with field 3 CC data
belongs to the same channel as field 1. The following pics have the fields reversed
because of the odd number of fields. I used top_field_first to tell when the channels
are reversed. See Table 6-1 of the SCTE 20 [Paul Fernquist]
0.54 (2009-04-16)
-----------------
- Add -nosync and -fullbin switches for debugging purposes.
- Remove -lg (--largegops) switch.
- Improve syncronization of captions for source files with
jumps in their time information or gaps in the caption
information.
- [R. Abarca] Changed Mac script, it now compiles/link
everything from the /src directory.
- It's now possible to have CCExtractor add credits
automatically.
- Added a feature to add start and end messages (for credits).
See help screen for details.
0.53 (2009-02-24)
-----------------
- Force generated RCWT files to have the same length as source file.
- Fix documentation for -startat / -endat switches.
- Make -startat / -endat work with all output formats.
- Fix sync check for raw/rcwt files.
- Improve timing of dvr-ms NTSC captions.
- Add -in=bin switch to read CCExtractor's own binary format.
- Fix problem with short input files (smaller 1MB).
- Clean up regular and debug output.
- Add -out=bin switch to write RCWT data.
- Remove -bo/--bufferoutput switch and functionality.
- [Volker] Added new generic binary format (RCWT
for Raw Captions With Time). This new format
allows one file to contain all the available
closed caption data instead of just one stream.
- Added --no_progress_bar to disable status
information (mostly used when debugging, as the
progress information is annoying in the middle
of debug logs).
- The Windows GUI was reported to freeze in some
conditions. Fixed.
- The Windows GUI is now targeted for .NET 2.0
instead of 3.5. This allows Windows 2000 to run
it (there's not .NET 3.5 for Windows 2000), as
requested by a couple of key users.
0.51 (unreleased)
-----------------
- Removed -autopad and -goppad, no longer needed.
- In preparation to a new binary format we have
renamed the current .bin to .raw. Raw files
have only CC data (with no header, timing, etc).
- The input file format (when forced) is now
specified with
-in=format
such as -in=ts, -in=raw, -in=ps ...
The old switches (-ts, -ps, etc) still work.
The only exception is -bin which has been removed
(reserved for the new binary format). Use
-in=raw to process a raw file.
- Removed -d, which when produced a raw file used
a DVD format. This has been merged into a new
output type "dvdraw". So now instead of using
-raw -d as before, use -out=dvdraw if you need
this.
- Removed --noff
- Added gui_mode_reports for frontend communications,
see related file.
- Windows GUI rewritten. Source code now included,
too.
- [Volker] Dish Network clean-up
0.50 (2008-12-12)
-----------------
- [Volker] Fix in DVR-MS NTSC timing
- [Volker] More clean-up
- Minor fixes
0.49 (2008-12-10)
-----------------
- [Volker] Major MPEG parser rework. Code much
cleaner now.
- Some stations transmit broken roll-up captions,
and for some reason don't send CRs but RUs...
Added work-around code to make captions readable.
- Started work on EIA-708 (DTV). Right now you can
add -debug-708 to get a dump of the 708 data.
An actually useful decoder will come soon.
- Some of the changes MIGHT HAVE BROKEN MythTV's
code. I don't use MythTV myself so I rely on
other people's samples and reports. If MythTV
is broken please let me know.
- Added new debug options.
- [Volker] Added support for DVR-MS NTSC files.
- Other minor bugfixes and changes.
0.46 (2008-11-24)
-----------------
- Added support for live streaming, ccextractor
can now process files that are being recorded
at the same time.
- [Volker] Added a new DVR-MS loop - this is
completely new, DVR-MS specific code, so we no
longer use the generic MPEG code for DVR-MS.
DVR-MS should (or will be eventually at least)
be as reliable as TS.
Note: For now, it's only ATSC recordings, not
NTSC (analog) recordings.
0.45 (2008-11-14)
-----------------
- Added autodetection of DVR-MS files.
- Added -asf to force DVR-MS mode.
- Added some specific support for DVR-MS
files. These format used to work
correcty in 0.34 (pure luck) but the
MPEG code rework broke it. It should
work as it used to.
- Updated Windows GUI to support the
new options.
- Added -lg --largegops
From the help screen:
Each Group-of-Picture comes with timing
information. When this info is too separate
(for example because there are a lot of
frames in a GOP) ccextractor may prefer not
to use GOP timing. Use this option is you
need ccextractor to use GOP timing in large
GOPs.
0.44 (2008-09-10)
-----------------
- Added an option to the GUI to process
individual files in batch, i.e. call
ccextractor once per file. Use it if you
want to process several unrelated files
in one go.
- Added an option to prevent duplicate
lines in roll-up captions.
- Several minor bugfixes.
- Updated the GUI to add the new options.
0.43 (2008-06-20)
-----------------
- Fixed a bug in the read loop (no less)
that caused some files to fail when
reading without buffering (which is
the default in the linux build).
- Several improvements in the GUI, such as
saving current options as default.
0.42 (2008-06-17)
-----------------
- The option switch "-transcript" has been
changed to "--transcript". Also, "-txt"
has been added as the short alias.
- Windows GUI
- Updated help screen
0.41 (2008-06-15)
-----------------
- Default output is now .srt instead of .bin,
use -raw if you need the data dump instead of
.srt.
- Added -trim, which removes blank spaces at
the left and rights of each line in .srt.
Note that those spaces are there to help
deaf people know if the person talking is
at the left or the right of the screen, i.e.
there aren't useless. But if they annoy
you go ahead...
0.40 (2008-05-20)
-----------------
- Fixed a bug in the sanity check function
that caused the Myth branch to abort.
- Fixed the OSX build script, it needed a
new #define to work.
0.39 (2008-05-11)
-----------------
- Added a -transcript. If used, the output will
have no time information. Also, if in roll-up
mode there will be no repeated lines.
- Lots of changes in the MPEG parser, most of
them submitted by Volker Quetschke.
- Fixed a bug in the CC decoder that could cause
the first line not to be cleared in roll-up
mode.
- ccextractor can now follow number sequences in
file names, by suffixing the name with +.
For example,
DVD0001.VOB+
means DVD0001.VOB, DVD0002.VOB, etc. This works
for all files, so part001.ts+ does what you
could expect.
- Added -90090 which changes the clock frequency
from the MPEG standard 90000 to 90090. It
*could* (remains to be seen) help if there are
timing issues.
- Better support for Tivo files.
- By default ccextractor now considers the whole
input file list a one large file, instead of
several, independent, video files. This has
been changed because most programs (for example
DVDDecrypt) just cut the files by size.
If you need the old behaviour (because you
actually edited the video files and want to
join the subs), use -ve.
0.36 (unreleased)
-----------------
- Fixed bug in SMI, nbsp was missing a ;.
- Footer for SAMI files was incorrect ( and
being closed).
- Displayed memory is now written to disk at end
of stream even if there is no command requesting
so (may prevent losing the last screenful).
- Important change that could break scripts, but
that have been added because old behaviour was
annoying to most people: _1 and _2 at the end
of the output file names is now added ONLY if
-12 is used (ie when there are two output
files to produce). So
ccextractor -srt sopranos.mpg
now produces sopranos.srt instead of sopranos_1.srt.
If you use -12, i.e.
ccextractor -srt -12 sopranos.mpg
You get
sopranos_1.srt and
sopranos_2.srt
as usual.
0.35 (unreleased)
-----------------
- Added --defaultcolor to the help screen. Code
was already in 0.34 but the documentation wasn't
updated.
- Buffer is larger now, since I've found a sample
where 256 Kb isn't enough for a PES (go figure).
- At the end of the process, a ratio between
video length and time to process is displayed.
0.34 (2007-06-03)
-----------------
- Added some basic letter case and capitalization
support. For captions that broadcast in ALL
UPPERCASE (most of them), ccextractor can now
do the first part of the job.
--sentencecap or -sc will tell ccextractor to
follow the typical capitalization rules, such
as capitalize months, days of week, etc.
So from
YOU BETTER RESPECT
THIS ROBE, ALAN
You get
You better respect
this robe, alan.
--capfile or -caf also enables the case
processing part and adds an extra list of
words in the specified file, for example:
--capfile names.txt
where names.txt is just a plain text file
with the proper spelling for some words,
such as
Alan
Tony
So you get
You better respect
this robe, Alan.
Which is the correct spelling. You can
have a different spelling file per TV
show, or a large file with a lot of
words, etc.
- ccextractor has been reported to
compile and run on Mac with a minor
change in the build script, so I've
created a mac directory with the
modified script. I haven't tested it
myself.
- Windows build comes with a File Version
Number (0.0.0.34 in this version) in case
you want to check for version info.
0.33 (unreleased)
-----------------
- Added -scr or --screenfuls, to select the
number of screenfuls ccextractor should
write before exiting. A screenful is
a change of screen contents caused by
a CC command (not new characters). In
practice, this means that for .srt each
group of lines is a screenful, except when
using -dru (which produces a lot of
groups of lines because each new character
produces a new group).
- Completed tables for all encodings.
- Fixed bug in .srt related to milliseconds
in time lines.
- Font colors are back for .srt (apparently
some programs do support them after all).
Use -nofc or --nofontcolor if you don't
want these tags.
0.32 (unreleased)
-----------------
- Added -delay ms, which adds (or substracts)
a number of milliseconds to all times in
.srt/.sami files. For example,
-delay 400
causes all subtitles to appear 400 ms later
than they would normally do, and
-delay -400
causes all substitles to appear 400 ms before
they would normally do.
- Added -startat at -endat which lets you
select just a portion of data to be processed,
such as from minute 3 to minute 5. Check
help screen for exact syntax.
0.31 (unreleased)
-----------------
- Added -dru (direct rollup), which causes
roll-up captions to be written as
they would on TV instead of line by line.
This makes .srt/.sami files a lot longer,
and ugly too (each line is written many
times, two characters at time).
0.30 (2007-05-24)
-----------------
- Fix in extended char decoding, I wasn't
replacing the previous char.
- When a sequence code was found before
having a PTS, reported time was
undefined.
0.29 (unreleased)
-----------------
- Minor bugfix.
0.28 (unreleased)
-----------------
- Fixed a buffering related issue. Short version,
the first 2 Mb in non-TS mode were being
discarded.
- .srt no longer has tags. No player
seems to process them so my guess is that
they are not part of the .srt "standard"
even if McPoodle add them.
0.27 (unreleased)
-----------------
- Modified sanitizing code, it's less aggresive
now. Ideally it should mean that characters
won't be missed anymore. We'll see.
0.26 (unreleased)
-----------------
- Added -gp (or -goppad) to make ccextractor use
GOP timing. Try it for non TS files where
subs start OK but desync as the video advances.
0.25 (unreleased)
-----------------
- Format detection is not perfect yet. I've added
-nomyth to prevent the MytvTV code path to be
called. I've seen apparently correct files that
make MythTV's MPEG decoder to choke. So, if it
doesn't work correctly automatically: Try
-nomyth and -myth. Hopefully one of the two
options will work.
0.24 (unreleased)
-----------------
- Fixed a bug that caused dvr-ms (Windows Media Center)
files to be incorrectly processed (letters out of
order all the time).
- Reworked input buffer code, faster now.
- Completed MythTV's MPEG decoder for Program Streams,
which results in better processing of some specific
files.
- Automatic file format detection for all kind of
files and closed caption storage method. No need to
tell ccextractor anything about your file (but you
still can).
0.22 (2007-05-15)
-----------------
- Added text mode handling into decoder, which gets rids
of junk when text mode data is present.
- Added support for certain (possibly non standard
compliant) DVDs that add more captions block in a
user data block than they should (such as Red October).
- Fix in roll-up init code that caused the previous popup
captions not to be written to disk.
- Other Minor bug fixes.
0.20 (2007-05-07)
-----------------
- Unicode should be decent now.
- Added support for Hauppauge PVR 250 cards, and (possibly)
many others (bttv) with the same closed caption recording
format.
This is the result of hacking MythTV's MPEG parser into
ccextractor. Integration is not very good (to put it
midly) but it seems to work. Depending on the feedback I
may continue working on this or just leave it 'as it'
(good enough).
If you want to process a file generated by one of these
analog cards, use -myth. This is essential as it will
make the program take a totally different code path.
- Added .SAMI generation. I'm sure this can be improved,
though. If you have a good CSS for .SAMI files let me
know.
0.19 (2007-05-03)
-----------------
- Work on Dish Network streams, timing was completely broken.
It's fixed now at least for the samples I have, if it's not
completely fixed let me know. Credit for this goes to
Jack Ha who sent me a couple of samples and a first
implementation of a semiworking fix.
- Added support for several input files (see help screen for
details).
- Added Unicode and Latin-1 encoding.
0.17 (2007-04-29)
-----------------
- Extraction to .srt is almost complete - works correctly for
pop-up and roll-up captions, possibly not yet for paint-on
(mostly because I don't have any sample with paint-on captions
so I can't test).
- Minor bug fixes.
- Automatic TS/non-TS mode detection.
0.14 (2007-04-25)
-----------------
- Work on handling special cases related to the MPEG reference
clock: Roll over, jumps, etc.
- Modified padding code a bit: In particular, padding occurs
on B-Frames now.
- Started work on CC data parsing (use -608 to see output).
- Added built-in input buffering.
- Major code reorganization.
- Added a decent progress indicator.
- Added TS header synchronization (so the input file no longer
needs to start with a TS header).
- Minor bug fixes.
0.07 (2007-04-19)
-----------------
- Added MPEG reference clock parsing.
- Added autopadding in TS. Does miracles with timing.
- Added video information (as extracted from sequence header).
- Some code clean-up.
- FF sanity check enabled by default.
