Apple Lossless (ALAC) audio support via TimedMediaHandler (transcode to oga)
Closed, DeclinedPublic


For uploading higher-quality audio source material, it would be nice to support open lossless formats; Apple Lossless is now available as open-source so this should be feasible:

Transcoding to our standard output formats (eg .oga Vorbis) would be useful to keep playback support consistent.

ffmpeg supports decoding alac for some time, so TMH transcoding would work.

To support upload without Firefogg, some way to detect if a selected .m4a file contains alac or aac would be needed. Could not find an existing implementation.

Not sure right now but I think we already have support for FLAC. Just because there is another OpenSource Codec for lossless audio storage it does not mean we have to implement it.

Kelson: How is ALAC related to FLAC? Also see comment 2.

I'm simply mixing different stuff. Sorry :(

Doesn't seem to be a lot of interest in ALAC currently, though it's feasible in theory. Closing as Declined, but if there's a strong use case can reopen.
