View Full Version : Unsync?
26th April 2005, 20:03
For some reason when i watch my own stream, the sound is coming after the video after a while. I dunno why :( im encoding everything on the stream using 320x240:20 using VP6.2 . Need more info? Pleae help me find out why it goes unsync after like 5 min.(People watching thinks its annoying)

hehe i like how the problem is with the audio yet you only give the video codec
things we need to know

If you are encoding from avi make sure that the keyframes are set to a very short period (like 500 ms). This will keep the sync better.
Converting a frame rate while encoding can cause problems too. Especially if you are encoding to a higher frame rate. 15 to 24 fps fouls up. 24 to 15 is fine.
NSV encoded Divx and MPEG1 files seem to always foul up.
MPEG2's (if they don't have a tweaked frame rate) work. AVI's usually work, and better if they have a very short key frame interval. All of these work better if you use the same frame rate as source and destination.
I have had some problems with some of the shouters. Slavas's shouter seems to skip some when the file changes. Slowly over hours the audio slips, just a hair every time the file changes. Restarting Winamp cures the problem.
If you look at the video without shoutcast and it looks ok, then the problem is with the shouter/server and not the encoder. 20 fps is not a frame rate I have used. I have good luck with 15, 18 and 24.
I'd look through the YP and find a bitrate/codec/frame setup that works and use the same. Since this stuff is all beta ware, copying success will save you a lot of time.
Of course, there is the uncertainty principle :-).

Opps :P I encode using AAC audio with 128kbps. It differs witch kind of video i encode from. I encode from (mostly) 30 fps to 20 fps.

Try a different frame rate.....

I find that if you change the "Min/max sync frame interval" to either your framerate or double your framerate (same in both boxes), then my videos stay perfectly in sync. See if it helps for you.

I'll try :) (I always wonder what that box was to)
