mplayer sais:
TS file format detected.
VIDEO MPEG4(pid=68)...AUDIO A52(pid=69) NO SUBS (yet)!  PROGRAM N. 1
Opened TS demuxer, audio: 2000(pid 69), video: 10000004(pid 68)...POS=8084
FPS seems to be: 250000/10000
Opening audio decoder: [liba52] AC3 decoding with liba52
Using SSE optimized IMDCT transform
AC3: 5.1 (3f+2r+lfe)  48000 Hz  384.0 kbit/s
Using MMX optimized resampler
AUDIO: 48000 Hz, 2 ch, s16le, 384.0 kbit/25.00% (ratio: 48000->192000)
Selected audio codec: [a52] afm:liba52 (AC3-liba52)
Checking audio filter chain for 48000Hz/2ch/s16le -> 48000Hz/2ch/s16le...
AF_pre: 48000Hz/2ch/s16le
AO: [oss] 48000Hz 2ch s16le (2 bps)
Building audio filter chain for 48000Hz/2ch/s16le -> 48000Hz/2ch/s16le...

vlc plays it also correctly.

put ffplay fails:
devbox:~/t# ./ffplay ~/teszt/outstream.ize
SDL_OpenAudio: 1 (mono) and 2 (stereo) channels supported
/root/teszt/outstream.ize: could not open codecs
devbox:~/t#

ideas? fixes? :)
