[MPlayer-users] Video and Audio async when play vlc rtp stream

[xie you]

Hello all,

I used vlc media player streaming/Transcoding Wizard to stream an mpeg
file to my local address 127.0..0.1, and the streaming method is RTP
Unicast, encapsulation format is MPEG TS, TTL is 1, and let the stream
play repeatedly.  ( The corresponding vlc command is
"vlc Kiwi-bike.mpeg  --sout
'#std{access=rtp,mux=ts,dst=127.0.0.1:1234}' --loop" )
Then I used mplayer to play the stream (mplayer rtp://127.0.0.1:1234).
It worked well in the first loop, but when the video repeated from the
beginning, the video became slow and the audio and video were async.
And the message "Your system is too SLOW to play this!" was displayed.
But if I used vlc to play this stream, there was no such problem.

Can somebody help me solve this problem? Thank you!

My mplayer is a checkout version at revision 27332.
My OS is Ubuntu 8.04
My media file is a mpeg-1 video file, and you can download it at:

My vlc version is: VLC media player 0.8.6e Janus
My hardware is: CPU: Intel(R) Core(TM)2 Duo CPU     E4500  @ 2.20GHz

Possible reasons, problems, workarounds:
- Most common: broken/buggy _audio_ driver
  - Try -ao sdl or use the OSS emulation of ALSA.
  - Experiment with different values for -autosync, 30 is a good start.
- Slow video output
  - Try a different -vo driver (-vo help for a list) or try -framedrop!
- Slow CPU
  - Don't try to play a big DVD/DivX on a slow CPU! Try some of the lavdopts,
    e.g. -vfm ffmpeg -lavdopts lowres=1:fast:skiploopfilter=all.
- Broken file
  - Try various combinations of -nobps -ni -forceidx -mc 0.
- Slow media (NFS/SMB mounts, DVD, VCD etc)
  - Try -cache 8192.
- Are you using -cache to play a non-interleaved AVI file?
  - Try -nocache.
