hi, for what its worth, I once messed around with capturing some AAC streams I had troubles getting them to work with my iPod (2nd gen Touch I think) until I did this: mp4box -add input.aac:mpeg4 -sbr -ipod output.m4a
The main flag required for iP*d compatibility seemed to have been specifiying the :mpeg4 (not just the obvious -ipod) Maybe give that a try and see if it helps!! NB you may not need the -sbr flag, depends if the stream is HE-AAC/AAC+ (AAC-LC + SBR), or HE-AACv2 (AAC-LC + SBR + PS) ...even if you don't need the flag, I don't remember if it even makes a difference... cheers, m mp4box should be available round and about, including here: http://www.videohelp.com/tools/mp4box ---------------------------------------- > From: [email protected] > To: [email protected] > Subject: RE: Flashaudio no longer available for Radio 4? > Date: Fri, 11 Mar 2011 15:26:03 +0000 > > > > > ---------------------------------------- > > > > > > Please run: > > mplayer -ao null -vo null -dumpaudio -dumpfile audio_file_fixed.aac > > original_audio_file.aac > > and test the _fixed.acc file in your iPod. > > > > I have a high degree of confidence it'll work. > > > > aB. > > > Hi > The mPlayer method doesn't work with 2nd generation iPod shuffles. > This type here :- http://img140.imageshack.us/img140/9927/shufflex.jpg > I've just tried. > > Apple skimped on the software with these 2nd generation shuffles. > The only aac files that Apple will guarantee them to play > are ones created by iTunes. > > I've also found that it will play m4a files created using neroAacEnc too. > > It's possible to convert the BBC aac files to nero m4a files like this:- > ffmpeg -i filename.aac -f wav - | neroAacEnc -ignorelength -if - -of > output.m4a > > But it's pointless, may as well just convert to mp3 with ffmpeg like this:- > ffmpeg -i filename.aac -acodec libmp3lame -ab 128k output.mp3 > > And to encode much quicker pipe to GOGO-no-coda with ffmpeg like this:- > ffmpeg -i filename.aac -f wav - | gogo -b 128 -q 0 stdin output.mp3 > > GOGO-no-coda cuts the encode time to around a third. > For example, to convert a 2 hour show takes me approx 12 minutes using ffmpeg > and libmp3lame. > With gogo it takes approx 4 minutes. > > _______________________________________________ > get_iplayer mailing list > [email protected] > http://lists.infradead.org/mailman/listinfo/get_iplayer > _______________________________________________ get_iplayer mailing list [email protected] http://lists.infradead.org/mailman/listinfo/get_iplayer
