- added JPEG image format support (input/output) |
|
|
|
|
|
version 0.4.4: |
|
|
|
- fixed some std header definitions (Bjorn Lindgren |
|
<bjorn.e.lindgren at telia.com>). |
|
- added MPEG demuxer (MPEG-1 and 2 compatible). |
|
- added ASF demuxer |
|
- added prototype RM demuxer |
|
- added AC3 decoding (done with libac3 by Aaron Holtzman) |
|
- added decoding codec parameter guessing (.e.g. for MPEG, because the |
|
header does not include them) |
|
- fixed header generation in MPEG-1, AVI and ASF muxer: wmplayer can now |
|
play them (only tested video) |
|
- fixed H.263 white bug |
|
- fixed phase rounding in img resample filter |
|
- add MMX code for polyphase img resample filter |
|
- added CPU autodetection |
|
- added generic title/author/copyright/comment string handling (ASF and RM |
|
use them) |
|
- added SWF demux to extract MP3 track (not usable yet because no MP3 |
|
decoder) |
|
- added fractional frame rate support |
|
- codecs are no longer searched by read_header() (should fix ffserver |
|
segfault) |
|
|
|
|
|
version 0.4.3: |
|
|
|
- BGR24 patch (initial patch by Jeroen Vreeken <pe1rxq at amsat.org>) |
|
- fixed raw yuv output |
|
- added motion rounding support in MPEG-4 |
|
- fixed motion bug rounding in MSMPEG4 |
|
- added B-frame handling in video core |
|
- added full MPEG-1 decoding support |
|
- added partial (frame only) MPEG-2 support |
|
- changed the FOURCC code for H.263 to "U263" to be able to see the |
|
+AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with |
|
this +codec ;) (JuanJo). |
|
- Halfpel motion estimation after MB type selection (JuanJo) |
|
- added pgm and .Y.U.V output format |
|
- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or |
|
output. |
|
- added pgmpipe I/O format (original patch from Martin Aumueller |
|
<lists at reserv.at>, but changed completely since we use a format |
|
instead of a protocol) |
|
|
|
|
|
version 0.4.2: |
|
|
|
- added H.263/MPEG-4/MSMPEG4 decoding support. MPEG-4 decoding support |
|
(for OpenDivX) is almost complete: 8x8 MVs and rounding are |
|
missing. MSMPEG4 support is complete. |
|
- added prototype MPEG-1 decoder. Only I- and P-frames handled yet (it |
|
can decode ffmpeg MPEGs :-)). |
|
- added libavcodec API documentation (see apiexample.c). |
|
- fixed image polyphase bug (the bottom of some images could be |
|
greenish) |
|
- added support for non clipped motion vectors (decoding only) |
|
and image sizes non-multiple of 16 |
|
- added support for AC prediction (decoding only) |
|
- added file overwrite confirmation (can be disabled with -y) |
|
- added custom size picture to H.263 using H.263+ (Juanjo) |
|
|
|
|
|
version 0.4.1: |
|
|
|
- added MSMPEG4 (aka DivX) compatible encoder. Changed default codec |
|
of AVI and ASF to DIV3. |
|
- added -me option to set motion estimation method |
|
(default=log). suppressed redundant -hq option. |
|
- added options -acodec and -vcodec to force a given codec (useful for |
|
AVI for example) |
|
- fixed -an option |
|
- improved dct_quantize speed |
|
- factorized some motion estimation code |
|
|
|
|
|
version 0.4.0: |
|
|
|
- removing grab code from ffserver and moved it to ffmpeg. Added |
|
multistream support to ffmpeg. |
|
- added timeshifting support for live feeds (option ?date=xxx in the |
|
URL) |
|
- added high quality image resize code with polyphase filter (need |
|
mmx/see optimization). Enable multiple image size support in ffserver. |
|
- added multi live feed support in ffserver |
|
- suppressed master feature from ffserver (it should be done with an |
|
external program which opens the .ffm url and writes it to another |
|
ffserver) |
|
- added preliminary support for video stream parsing (WAV and AVI half |
|
done). Added proper support for audio/video file conversion in |
|
ffmpeg. |
|
- added preliminary support for video file sending from ffserver |
|
- redesigning I/O subsystem: now using URL based input and output |
|
(see avio.h) |
|
- added WAV format support |
|
- added "tty user interface" to ffmpeg to stop grabbing gracefully |
|
- added MMX/SSE optimizations to SAD (Sums of Absolutes Differences) |
|
(Juan J. Sierralta P. a.k.a. "Juanjo" <juanjo at atmlab.utfsm.cl>) |
|
- added MMX DCT from mpeg2_movie 1.5 (Juanjo) |
|
- added new motion estimation algorithms, log and phods (Juanjo) |
|
- changed directories: libav for format handling, libavcodec for |
|
codecs |
|
|
|
|
|
version 0.3.4: |
|
|
|
- added stereo in MPEG audio encoder |
|
|
|
|
|
version 0.3.3: |
|
|
|
- added 'high quality' mode which use motion vectors. It can be used in |
|
real time at low resolution. |
|
- fixed rounding problems which caused quality problems at high |
|
bitrates and large GOP size |
|
|
|
|
|
version 0.3.2: small fixes |
|
|
|
- ASF fixes |
|
- put_seek bug fix |
|
|
|
|
|
