Version 0.55

Release Date: Aug 10, 2009
Download(s):
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 NTSCthey repeat every 4th frame. Some pics have 3 fields of CC data with field 3 CC databelongs to the same channel as field 1. The following pics have the fields reversedbecause of the odd number of fields. I used top_field_first to tell when the channelsare reversed. See Table 6-1 of the SCTE 20 [Paul Fernquist]

Version 0.54

Release Date: Apr 17, 2009
Download(s):
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.

Version 0.53

Release Date: Feb 25, 2009
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 --no_progress_bar switch to help readability of redirected 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.

Version 0.52

Release Date: Dec 21, 2008
Download(s):
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

Version 0.50

Version 0.49

Release Date: Dec 10, 2008
[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.
Other minor bugfixes and changes.

Version 0.46

Release Date: Nov 25, 2008
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.

Version 0.45

Release Date: Nov 15, 2008
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.
fUpdated 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.

Version 0.44

Release Date: Sep 11, 2008
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.

Version 0.43

Release Date: Jun 21, 2008
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.

Version 0.42

Release Date: Jun 18, 2008
The option switch "-transcript" has been changed to "--transcript". Also, "-txt" has been added as the short alias.
Windows GUI
Updated help screen

Version 0.41

Release Date: Jun 16, 2008
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...

Version 0.40

Version 0.39
