I also plan to improve the bitrate control which is too simplistic.

- I rewrote the mpeg audio layer 2 compatible encoder from scratch. It
36
  is one of the simplest encoder you can imagine (800 lines of C code
37
  !). It is also one of the fastest because of its simplicity. There
38
  are still some problems of overflow. A minimal psycho acoustic model
39
  could be added. Currently, stereo is supported, but not joint
40
  stereo.

- I rewrote the AC3 audio encoder from scratch. It is fairly naive,

  but the result are quiet interesting at 64 kbit/s. It includes

  extensions for low sampling rates used in some Internet

  channels are simply handled as two mono channels.

- The mpeg audio layer 3 decoder was rewritten from scratch. It uses
47
  only integers and can be 16 bit precision for the synthesis filter
48
  at the expense of a slight precision loss. A slower bit exact mode
49
  is available too for compliance testing.

Short term glantau's fixes:
7
- regression tests (done).
8
- mpeg1/2 decode fix (unfortunately not much speed increase) (done)
9
- fix WORDS_BIGENDIAN issue (done)
10
- remove win project files (done)
11
- remove sub_xxx functions (done)
12
- mpeg2 transport stream support (decoding done)
13
- improved auto guess for formats (api change again in demux) (done)
14
- fix mpeg format tracking + handle frame rate change (done)
15
- suppress strlcpy (done)
16

  
17
- split mux/demux functions. (done)
18
- use av_new_stream() (partially done)

6
Short term fixes:
7
- mpeg audio fix
8
- ffserver fix
9
- fix stream selection (aka map) syntax. Start stream numbers at 1 in
10
  listing. Find a syntax for stream ids (such as TS pids).
20 11
- reconstruct mpeg header frame rate in telecine case so that we do
21
  not need to ifner the real rate if it is not possible.
12
  not need to infer the real rate if it is not possible.
22 13
- remove unused DCT code.
23
- mpeg audio fix
24
- AV sync fix (new api for demux)
25
- RTP streaming support in ffserver
14
- AV sync fix
15
- RTP/RTSP streaming support in ffserver and in libav
26 16
- minimal support of video in ffplay
