Thank you. 

It exists there is even a Function with av_frame_get_best_effort_timestamp.
hmm.. my 00:19 Clip with 93MB only got to 90MB... and i reduced Bitrate/and
But it can't be your code ... not sure what to think... 

But i noticed it only today... it gets only out of sync while playing for a
while... if you use scrubbing on player it resync somehow.

Thank to you i have new idea... to check this stuff with other Formats.
We did face this with ProRes/DNxHD ... 

I looked the Code from ffmpeg.c and they do a lot with pts/dts, its
mind-blowing... they dealing somehow with dropped frames or duplice frames..
its hard to understand for newcomer.
