I am currently testing the web audio api. The method context.decodeAudioData fails when attempting to play mp3 or m4a file types. Only wav files appear to work. If this is not the right forum for this question, is there a developer forum?

Thanks

Maybe this bug will add this support on Mac.

  • bug 851290 - Use GStreamer on Mac for H.264/MP3/AAC playback (instead of AV Foundation)

If I set media.gstreamer.enabled (Firefox 24+) to true then at least I can play MP3 files with the built-in HTML5 player.
So you can check if you have this pref on Mac and if it has effect.

hello, i think this might be the case because firefox on mac os x doesn't support mpeg-encoded media files natively yet. those formats are currently supported on windows 7, linux (starting from firefox 24), on android and firefox os.

the ongoing implementation work for mac os x is tracked in bug #851290.
