Based on svn r178, and linking with recent system ffmpeg instead of that provided by dvbcut, I observe inconsistencies in fps written to mpg file. i.e. I reload the mpg into dvbcut and see that the fps value sometimes shows 50 instead of the usual 25
When: * starting an export on a B-frame or P-frame then the reloaded file starts at 50fps and reverts to 25fps after a small number of I-Frames. * ending an export on a B-frame or P-frame then the reloaded file can jump from 25fps to 50fps at the end. * starting and ending on I-Frame then everything shows 25fps Even with the variable fps, the exported file appears to play normally in vlc. The above effect does not occur with ffmpeg from dvbcut. Debug shows that mpgfile::fixtimecode() is sometimes detecting frc==6 instead of frc==3. With the older ffmpeg, fixtimecode exits early rather than detect frc==6 I'm working with terrestrial dvb in the uk. I have the seen the problem with several channels. I presume it is due to a change in the ffmpeg libraries rather than in the ts file.
