----
- 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
----
- 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
----
- 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
----
- 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
----
- [Volker] Fix in DVR-MS NTSC timing
- [Volker] More clean-up
- Minor fixes

0.49
----
- [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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- Fixed bug in SMI, nbsp was missing a ;.
- Footer for SAMI files was incorrect (<body> and
  <sami> tags were being opened again instead of
  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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- Minor bugfix.

0.28
----
- Fixed a buffering related issue. Short version,
  the first 2 Mb in non-TS mode were being
  discarded.
- .srt no longer has <font> 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
----
- Modified sanitizing code, it's less aggresive
  now. Ideally it should mean that characters
  won't be missed anymore. We'll see.

0.26
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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
----
- 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.
