Unfortunately, I can't make them able to play by ffplay or mplayer.
The latest ffplay exits with:
./ffplay ../test_data/stream01.avs
FFplay version SVN-r15191, Copyright (c) 2003-2008 Fabrice Bellard, et al.
configuration:
libavutil 49.10. 0 / 49.10. 0
libavcodec 51.71. 0 / 51.71. 0
libavformat 52.22. 0 / 52.22. 0
libavdevice 52. 1. 0 / 52. 1. 0
built on Sep 4 2008 13:59:55, gcc: 4.2.3 (Debian 4.2.3-1)
[mp3 @ 0x883fff0]Could not find codec parameters (Audio: mp1, s16, 256 kb/s)
../test_data/stream01.avs: could not find codec parameters

I even tried ffmpeg revision 9792. And the result was the same.
May be *.avs files on avs.org.cn are changed since time you played them?
The problem seems to be that file header is parsed incorrectly
and demuxer's probe fail.
Could you please check if you can play these files now or
point on what I am doing wrong?
