[Libav-user] A/V Sync problem

[Tomislav Timic]

Hello,
I am building custom transcoder/abr packager solution using libav, and i
implement demux and mux of mpeg 2 ts and iso bmff, but i am having problem
when encoding video and audio, video encoding is a lot slower, and output
stream gets out of sync.
My question is how should i approach this problem, should I decode/encode
on separate threads, and sleep for delay that i calculate based on pts, or
should I implement some filter in libav?
I just want to hear experience from people who solved it.
Thank you. Regards
