[FFmpeg-devel] [PATCH][RFC] TechnoTrend PVA Demuxer

In order to make it possible to deprecate MPlayer's libmpdemux in the 
future, I started working on a few demuxers that lavf is still missing. 
This is the first one.


All samples play correctly.

I did not however implement seeking yet. That's the RFC. How should I 
proceed? There's no index. PVA files are encapsulated MPEG-ES (for video) 
and MPEG-PES (for audio) packets. Should I just rely on the caller 
(MPlayer, ...) feeding it a new byte-position and resync on the AV-syncword 
at the start of read_packet() ? And if I do so, can I use url_fseek or does 
that ruin the ability to pipe the input to ffmpeg?
