--------------------------+---------------------
When using tstools' tsreport tool (http://code.google.com/p/tstools/) I
got this list of PTS:
126000, 129750, 133500, 137250, 141000, 144750, 148500, 152250, 156000,
126000, 159750, 163500, 167250
When using FFmpeg's filter showinfo the PTS timestamps are totally
different:
0, 41667, 83333, 125000, 166667, 208333, 250000, 291667, 333333, 375000,
416667, 458333
When playing the video using libavcodec/libavformat, the timestamps are
the same as the ones tsreport shows.
ffmpeg -y -vf showinfo -i seekbug01min.ts -f rawvideo /dev/null
