Absolutely agree that no further deps should be added to get_iplayer unless we're sure they're necessary.

Surely it must be possible with the tools we have already to remux properly.

Maybe ffmpeg has a --flag that will allow it to produce compatible files?

It doesn't seem like this option has yet been thoroughly explored.

I'm not sure that --m4a option is necessary, as the current .aac files (or their container, specifically) are known to be broken. There are a number of players they don't work on, and they only play on the systems they do because these OSS players (VLC, mplayer) are particularly forgiving.
