[Libav-user] Video Timing

Can someone point me at something that shows how to get reliable stream

Depending on the video, video_packet->pts = INT64MIN or video_packet->pts
is equivalent to the frame index or ... pts increments in approximate units
of 3000/frame... what builds this 3000 number?  Ticks per frame is often 2;
which is needed...

I understand how the numerator/denominator work; but depending on the video
the encoding of all these informations is unreliable...

how do I get a reliable pts for the video?  Audio seems easy; since it's a
slow steady, packed stream...

so I'm pretty close overriding and just using the encoded_frame data from
the video packet to determine time...

but I ran into another that I'm not sure what's wrong with it...

And by now, why isn't all of this just fixed so after the decoder I know
exactly what the time should be? :)
