2000-08-15 Gernot Ziegler <gz@lysator.liu.se>
* Created intial automake & autoconf files (still lot of bugs, I
guess ;) )
* Created libmovtar (read/write support not complete yet)
* Created libmjpeg
2000-12-07 Andrew Stevens (as@comlab.ox.ac.uk)
* 1.3b2 release. Tag: Rel1_3Beta2
* Initial support for Software-only mjpeg playback.
* Seperated mpeg encoding tools from tools used to extract raw
audio/video from mjpeg.
* Initial support for transcoding using patched mpeg2dec and
ac3dec packages.
* Further speed and quality improvements to MPEG-1 encoding with
mpeg2enc. Bugs fixed. Run-time selection of MMX/extended
MMX/SSE/3D-Now! routines as appropriate.
* mplex now much faster, debugged, and supports correct VCD
compatible multiplexing and splitting of streams into multiple files.
Initial MPEG-2 video support. Supports layer 3 audio and (hopefully)
MPEG audio V2 and V2.5 though these don't look too useful...
* Bug fixes and support for software-only playback of mjpeg.
2001-01-25 Andrew Stevens (as@comlab.ox.ac.uk)
* 1.3b3 release. Tag: Rel1_3Beta3
* Refinement if field based motion compensation type selection.
Replacing sad with variance as selection criterion.
* Initial SVCD support in mplex and mpeg2enc. Initial support for
handling poor chrominance matching in motion compensation.
* Support for new combined LML33/buz/DC10/DC10+ driver.
* Support for 422 MJPEG from xawtv capture tool.
* More robust audio driver handling (SB-Live now works!).
2001-01-25 Andrew Stevens (as@comlab.ox.ac.uk)
* 1.4 release Tag: Rel1_4
* Dynamic GOP sizing and SMP support in mpeg2enc. Minor refinements to
motion compensation.
* Signficant enhancement and bug-fixing of lavrec and lavtools.
* Addition of yuvscaler and yuvplay, ypipe and yuv2lav utilities
* Unified output logging format and consistent command line flags.
* Lots of bug fixes.
* Man pages.
* Binary packages.
2001-06-21 Andrew Stevens (as@comlab.ox.ac.uk)
* 1.5 series
* Single pass multiplexer. VBR audio multiplexing support.
* Splitting mpeg encoder into re-entrant library and front-end(s).
* Switch to multi-frame ppm

$Log: ChangeLog,v $
Revision 1.16 2011/05/14 11:59:36 waldviertler
documented some (hopefully most to all) changes since the last release
Revision 1.15 2008/11/29 19:31:20 wackston2
Trial fix: stop sampling frames at Q floor (where Actual bits *expected* to be
< Target bits) to compute mean Target/Actual ratio after pass2
reencoding.
Tidying: remove some redundant inclusion of config.h
Revision 1.14 2001/07/08 21:21:15 wackston
Added VBR audio support.
Fixed wav headers so they indicate a long not a short stream
if header is aborted...
Revision 1.13 2001/06/23 14:14:41 wackston
First stage of single-pass muxing. Video now single-pass.
Revision 1.12 2001/05/26 12:37:50 wackston
Tidying doco for packaging...
Revision 1.11 2001/05/10 19:52:36 wackston
Tidyings and fixing up to the 1.4 release.
Revision 1.10 2001/05/06 15:59:15 wackston
Bug fix for m/c type select in motion.c also made field M/C use
chroma info.
Minor fixes elewhere related consistenct logging / command lines.
Revision 1.9 2001/02/07 14:45:05 wackston
Minor tidyings and bug-fixes ready for 1.3b3 release.
Revision 1.8 2001/01/25 20:11:29 wackston
Initial SVCD support in mplex. Update TODO files..
Revision 1.7 2000/12/19 14:34:06 wackston
*** empty log message ***
Revision 1.6 2000/12/19 14:29:14 wackston
Tagging for beta2 release.
Revision 1.5 2000/12/15 19:34:09 wackston
MPEG-2 encoding has been restored to working order. Still some doubts about
whether its 100% correct again but as far as I can tell any remaining bugs are just sub-optimality rather than crass errors.
mplex now support MPEG-2 mux-ing *and* layer 3 audio.
Revision 1.4 2000/12/07 19:09:04 wackston
*** empty log message ***
Revision 1.3 2000/12/07 16:44:50 wackston
Still more minor updates to doco files for release.
Revision 1.2 2000/12/05 09:34:05 wackston
Put Log substiution into ChangeLog
Changes to lavtools-1.2
- A.Stevens Merged in improvements to mpeg2enc plus useful additional
tools.
- G.Ziegler Initial merge of mmx-ed JPEG libs and movtar support.
Detached jpeg-6b-mmx and libmovtar into own packages.
Changes to lavtools-1.1
- added MPEG video and audi encoders for usage with
AVI/Quicktime files and Edit lists
- lavplay now can not more output files from edit lists,
this is taken over by lavtrans in the utils directory
- lavrec: different decimations in x and y direction
possibility to capture sub areas
time lapse
- lavplay: "zoom to fit"
- xlav: better user interface
- device names for video/audio/mixer device may be set
by environment variables
- much more small things
Changes to lavtools-1.0
- Full Quicktime support in recording and playing
- Support of multiple files to overcome 2 GB limit
- perfect audio/video synchronization in recording and playback
for lip-synchronous videos even after hours of playing.
- single frame (is it called stop motion?) capture
- GUI to lavplay - use your linux PC as a great video recorder
- support of (simple) editing in the GUI: cut your video clips
as you like
- lavplay supports concatenating video clips, splitting off audio
separating video into single images
- option in lavrec to wait for user input before starting
- support for other audio input sources in lavrec
- steering of lavplay (forward, backward, pause etc.) with commands
(for real command line hardliners)
Changes to lavtools 1.9.0 (in no particular order)
- added changes to support the compiling for new CPUs
- some autoconf/configure fixes (x11 and other libs
- patch to compile png2yuv with newer png lib
- clean upf for vrious compiling problems
- jpegutil fix for neser libjpeg
- mpeg2enc some more two-pass encoding support
- mpeg2enc fixes for bit rate problems
- mplex added support for subtitle streams from tcextract
- mplex small fixes
- y4mdenoise better, faster, fixed the problem in dark/cloudy areas
- fixes for the __progname problem
- yuvdenoise god speed up by a SSE2 ASM version of some code
