Audio/Video Out of Sync

[S Carr]

Anyone else running into issues of AV being out of sync? I've had this
happen on a couple of downloads recently, not quite sure whether it's
a BBC issue with the video file or an issue with get_iplayer (or it's
various underlying components).

The last ones I had AV sync issues with were the Olympic opening
ceremony and the latest episode of Full Steam Ahead.

Versions are:
- get_iplayer v2.95
- ffmpeg version 2.8.6-1ubuntu2
- AtomicParsley 0.9.2~svn110-4

The command I ran to download the Olympic opening ceremony was...
~/get_iplayer/get_iplayer --pid-recursive --pid b07mzrxt --modes=best
--versions=editorial,default --versions=editorial,default
--fatfilename --whitespace

Looking at the output, I see the following warning messages, so I'm
not sure if this has something to do with it...

Re-downloading doesn't seem to have fixed it either :(
