 |
|
I can't for the life of me figure this out... some files are fine.
I've tried xine/mplayer/gst-player.
I've tried diffrent audio codecs in mplayer, and diffrent video codecs (and diffrent video out methods).
using alsa-drivers in kernel 2.6.6-rc1-mm1 with a audigy soundcard, and with a ati radeon display adapter running ati-drivers-3.2.8.
anyone have any suggestions? |

If you mean that sound and pictures are sometimes out of sync then I've noticed this too. It's only for a few files as you've said. Sadly I have no idea how to fix this.

what confuses the heck out of me is that I can play other files using the same video codec, video out, audio out, and sound codec, and they'll play fine. But this one file I cant seem to play with any codec (without desync). And it plays fine on windows.
Note that it isn't just one file, but my test stuff is one file :p |

with mplayer try adding '-autosync 1'
its usually due to a bad encode of the file, frames missing and such, you can also try adjusting the 1 to other values, but 1 should work |

doesen't work, exactly the same delay :/, tried with 0 1 and 20, I tried a bunchload of other options too mentioned around, can't remember em all now, all seem to have no effect at all :/ |

The test file I use has some talking 72 seconds into the file, which is a very easy place to spot desync's.
I've been trying
mplayer -ss 72 <file>
visible desync
mplayer -ss 72 -delay 30 <file>
desync seems to be happening at the EXACT same spot
then I tried:
mplayer -autosync 0 -mc 0 angel.501.hdtv-lol.avi -delay 60 -nobps
exact same desync as with no delay.
seems it's autocorrecting something wrong, and I can't figure out how to disable it. |

| seems -delay works aslong as I dont fast forward. I found -delay -0.7 works, annoying as hell that this only bugs out in linux though :/ |
