Current frame count in H.264 playback incorrect, playback ends early

[stuartm]

At some point in the last 2-3 weeks the calculation of current position in H.264 recordings from BBC One HD, BBC HD, Channel 4 HD and possibly others in UK has significantly wrong.

For BBC HD it seems that every 8th frame is not counted toward the framesPlayed total (we ignore frames with 'no video', possibly B frames) and this can ultimately result in the position being behind actual by several minutes.

For C4 HD it seems the position is way ahead of the wall time, this causes playback to exit as though EOF has been reached even though you're only halfway through the recording.

As sample of BBC HD is already available and I'll add a sample of Channel 4 HD too.
