We seem to have established that ffmpeg isn't generating entirely valid mpeg4 files, I wonder does it work if you pipe it through MP4Box on the way? thus: ffmpeg -i "Bells_on_Sunday_-_27_03_2011_b00zq9t8_default.flv" -acodec copy -absf aac_adtstoasc temp.m4a MP4Box -add temp.m4a:mpeg4 -sbr -ipod Bells-on-Sunday.m4a AtomicParsley Bells-on-Sunday.m4a --artist "BBC Radio 4" --title "Bells on Sunday" --overWrite ... though if this works I'd be reluctant to advocate adding another program dependency to get_iplayer - I'd be inclined to consider it a workaround. I don't have an ipod and itunes to hand, but for a test file I do have here mp4info reports different things. note the kbps in the audio track... it suggests (as I think we're establishing) that ffmpeg mangles the metadata atoms in a way that makes them inconsistent with what's actually in the file. The ffmpeg patch did something in the textual metadata, it looks like there's another bug in the atom(s) that describe the audio stream. ffmpeg-current aac -> m4a: mp4info version 1.6 Classic_Chandler_2._The_Lady_in_the_Lake.m4a: Track Type Info 1 audio MPEG-4 AAC LC, 5400.102 secs, 0 kbps, 44100 Hz Name: Classic Chandler: 2.
