#389: Problem seeking in MPEG TS/H.264 files
----------------------+---------------------

----------------------+---------------------
 When seeking to a specific time in a MPEG-TS file, seeking silently fails.

 Thus, av_seek_frame( format_context, videostream, pts, AVSEEK_FLAG_ANY );
 results in a seek to the first timestamp in the file (126000), and
 av_seek_frame returns 0 indicating that the seek succeeded.

 The sample was generated with FFmpeg+libx264.
