| |
| |
| 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 |
| |
| |

| bitrates and large GOP size |
| |
| |
| |
| version 0.3.2: small fixes |
| |
| - ASF fixes |
| - put_seek bug fix |
| |
| |
