No they do not play, but no 'header error' or 'time out' error. They
play OK (with no delay) if I use EasyTag and change a tag.
OK
Well the FFmpeg update fixed it for the Shuffle.
The m4a files play straight off without needing EasyTAG any more.
So, currently in my version of get_iplayer:
1 rtmpdump downloads flv
2 ffmpeg remuxes flv to aac
3 ffmpeg remuxes aac to m4a and removes ADTS
4 atomicparsley tags the m4a
Your testing shows that ffmpeg at least is causing a problem with it's
m4a handling and that EasyTag corrects this
