Answer 1

I did something like this at some point using libx264 and vorbis.

A code example. https://github.com/Themaister/SSNES/blob/master/record/ffemu.c

The basic idea is that you have to set timestamps yourself in the AVFrame when you want to encode it. Then you can take that packet and write it with av_interleaved_write().
