416- added ASF demuxer
417- added prototype RM demuxer
418- added AC3 decoding (done with libac3 by Aaron Holtzman)
419- added decoding codec parameter guessing (.e.g. for MPEG, because the

e0db8cfb
DB
430 decoder)
431- added fractional frame rate support
de6d9b64 432- codecs are no longer searched by read_header() (should fix ffserver

de6d9b64 446- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
447 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
448 this +codec ;) (JuanJo).
449- Halfpel motion estimation after MB type selection (JuanJo)
450- added pgm and .Y.U.V output format
de6d9b64
FB

452 output.
453- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 454 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 455 instead of a protocol)

483 AVI for example)

e0db8cfb 495 URL)
de6d9b64 496- added high quality image resize code with polyphase filter (need

503 done). Added proper support for audio/video file conversion in
de6d9b64 504 ffmpeg.
