[Ffmpeg-devel] avformat/av_estimate_timings_from_pts re-reads packets

[Kenneth Aafløy]

Hi,

When implementing a real-time application for viewing telly I noticed that 
whenever I started watching a new channel the stream reader would read some 
amount of packets, seek back to the start of the stream, then re-read them.

I have traced this down to av_estimate_timings_from_pts, where the first thing 
that is done is to flush the packet queue. AFAICS this is only called 
indirectly from av_find_stream_info, which makes it safe to assume that the 
packets in the queue is already usable.
