Description

Hi,

ffmpeg seems unable to sync audio & video coming from tvheadend. I've tried various switches to ffmpeg (like -copyts -isync -async 1 -vsync 1 and many more), but never succeeded. The sound is always 1-2 seconds behind the video, unless i'm streaming the same channel that is currently being used by another client (for example xbmc), which results in some 10ths of a second delay.

After speaking to people in #ffmpeg, it seems this is an issue with tvheadend. Ideally ffmpeg should automatically be able to keep audio & video in sync.

I definitely concur that there are some sync issues. E.g. when using VLC I always have to manually delay the audio by 300-500ms to get it into sync with video.

I'm find this as well. Are there any settings I can tweak?
