Replay pauses consistently (priority somewhere between major and minor really)

[Joe Green]

Having just upgraded to the new one (delx-webdl-cb2a08b54323) I successfully downloaded from iView only to find that reply occasionally pauses for several seconds (in the same places every time). My conversion ts-to-mp4 said the following and I wonder if it's related and what the cure might be:

Incidentally, having modified the Python so I could keep the .ts, I find that VLC plays the .ts .without pausing. (The pauses appear for the .mp4 on the PVR and with VLC.) I doubt that the PVR will cope with a .ts though.

Hmm I upgraded to the latest ffmpeg and the problem has gone away.

FWIW I note that the original pauses were every 30 seconds.

Fixed with latest ffmpeg (N-73510-g033dc39, officially 2015-07-10).

Glad you managed to solve it :)

Since I started using Arch Linux instead of Ubuntu I tend to not notice these issues with older versions of ffmpeg.
