Comment (by baudouin0):

 Ok I understand - when I played the ts steam in VLC media player or our
 own player (using ffmpeg) we saw the issue in that the picture would
 stutter with the P-frames comming out twice as fast and then a pause
 before the next I-frame. As that is quite complicated we looked into just
 compiling ffmpeg on its own and found this. Your right that it could be
 another issue we have not yet found. However that variable being set to
 zero is not correct. I may be able to use ffplay to see what the fix does.
 My understanding of what was intended in the code is limited so I not sure
 on the correct fix.

 I will try ffplay and get back to you.
