@ -9,13 +9,13 @@ Short term:
- seeking API and example in ffplay
- parse_only mode
- use AVFMTCTX_DISCARD_PKT in ffplay so that DV has a chance to work
- fix windows compile
- add man page
- add RTSP regression test (both client and server)
- make ffserver allocate AVFormatContext
- clean up (incompatible change, for 0.5.0):
* AVStream -> AVComponent
* AVFormatContext -> AVInputStream/AVOutputStream
* CODEC_ID_MP3LAME and CODEC_ID_MP2 -> CODEC_ID_MPEGAUDIO
* suppress rate_emu from AVCodecContext
- add av_log() in libavcodec and suppress all printf
- add new float/integer audio filterting and conversion : suppress
CODEC_ID_PCM_xxc and use CODEC_ID_RAWAUDIO.
