Comment (by Peter Bennett):

 This fix only applies to avsync2. Elapsed playback time is now based on
 the timecodes of the frames rather than count of number of frames played.
 This should help with any video or situation where the timecode advances
 at the wrong rate.

 I have a 30 minute recording that I played using mediacodec on shield at
 1.5x. Before this change it reverted to 1.0x and showed 30 playback
 minutes when it was actually only 2/3 through (at the 20 minute point
 approximately). With the patch the timings are correct and it reaches the
 end of the recording correct;y at the 1.5x speed, also the timings
 displayed with Info are now correct.

 I have done some tests with cutpoints also, and they seem OK with this
