The rational for this is another issue that plex has exposed.  When it is
conducting a transcode of video to HLS for streaming, my father noticed
artifacts when played on his GoogleTV (NSZ-GT1).  He sent me a test file
and I reproduced it on my device of the same model.  It is important to
note that the artifacts were not present when streaming to VLC or QuickTime
Player.  I copied the command-line that plex used, and conducted all of the
following tests using FFmpeg git.

Transcode to HLS: artifacts on playback
Transcode to TS: playback is fine
Cat HLS segments into a single TS: playback is fine
Segment single TS file to segments: artifacts on playback
Segment single TS file to segments using Apple's HLS segmenter: playback is
fine

At this point I carefully examined the differences between Apple's HLS
segmenter output and FFmpeg's.  Among the considerable differences, I
noticed that the video PES packets always had a 0 length.  So I continued:

Transcode to HLS using FFmpeg with 0 length PES packets: playback is fine.
Segment single TS to segments with 0 length PES packets: playback is fine.

All failures mentioned are only on the GTV since it is the only player on
which I could reproduce artifacts.  I only tested the GTV, VLC, and
QuickTime Player though, so my test case is limited.  I do not know if
other players exhibit this issue.

Since it was useful last time, I have uploaded the test file as
hls_pes_packet_length.m4v along with its associated txt file which contains
the transcode command-line that was used.

  txd: do not set the codec timebase.
Merged-by: Michael Niedermayer <michaelni@gmx.at>

The parser has no way of knowing video duration, and therefore no video
parsers set it.

Currently, if a decoder sets AVFrame.pts, we'd send the same timestamp
to it twice, which is wrong.

It is not supposed to be changed from outside of lavc.
Set the stream timebase and average framerate instead.
