421- added ASF demuxer
422- added prototype RM demuxer
423- added AC3 decoding (done with libac3 by Aaron Holtzman)
424- added decoding codec parameter guessing (.e.g. for MPEG, because the

427 play them (only tested video)
428- fixed H.263 white bug

e0db8cfb
DB
435 decoder)
436- added fractional frame rate support
de6d9b64 437- codecs are no longer searched by read_header() (should fix ffserver

de6d9b64 451- changed the FOURCC code for H.263 to "U263" to be able to see the
e0db8cfb
DB
452 +AVI/H.263 file with the UB Video H.263+ decoder. MPlayer works with
453 this +codec ;) (JuanJo).
454- Halfpel motion estimation after MB type selection (JuanJo)
455- added pgm and .Y.U.V output format
de6d9b64
FB
456- suppressed 'img:' protocol. Simply use: /tmp/test%d.[pgm|Y] as input or
457 output.
458- added pgmpipe I/O format (original patch from Martin Aumueller
dd5cf2ad 459 <lists at reserv.at>, but changed completely since we use a format
e0db8cfb 460 instead of a protocol)

488 AVI for example)
