Comment (by andreasg):
The results listed above did not seem to be completely plausible. Thus, I
fixed my application to access "best_effort_timestamp" via "av_opt_ptr"
and to use "pkt_pts" in the one revision that didn't provide that. I also
stopped using "av_rescale".
Here are the new results. Unfortunately, this is still not a commit that
mentions h264.
