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.
