Apple Lossless Audio Codec support
Why don't MediaCoder support ALAC (Apple Lossless Audio Codec) - m4a? iPods and iPhones are popular, so it would be great, if MediaCoder supported this format.
Re: Apple Lossless Audio Codec support
Because... there is no open source ALAC encoder...?

Re: Apple Lossless Audio Codec support
According to changelog for version 0.5 of FFmpeg at http://ffmpeg.org/changelog.html an ALAC encoder is built in. But I don't know how to tell MediaCoder to use that one. Maybe another person can help.

Re: Apple Lossless Audio Codec support
Ah, I forgot...
If you do not want to wait...
Edit mccodecs.xml,
go to ffmpeg audio config and add (after MP2 for example)
change
to
and change
to
Edit mccore.xml,
change
to
After... just select FFmpeg as audio encoder and on right side choose ALAC audio format (+of course disable video tab).

Re: Apple Lossless Audio Codec support
Hi, after a long time.
I, unfortunately, have to use dbPoweramp to convert FLAC to ALAC, but I really look forward to seeing one day ALAC converting in MediaCoder as well as multi-threading support.
BTW: Do ALAC codec need to be open to use it in this app? How then dbPoweramp transcode to ALAC?
BTW 2: Is there any way to interest MediaCoder developers in ALAC transcoding? Any feedback form to post?
Sorry for posting after 6 months, but I've just remembered posting sth on this forum and checked, if there were any replies.
// @Placio74 dzięki

Re: Apple Lossless Audio Codec support
Have you noticed there is ALS option in audio encoder list?
When things work together, things work.
Re: Apple Lossless Audio Codec support
ALS is not ALAC.
ALS is an extension to MPEG-4 to allow lossless compression.
ALAC is an audio codec for lossless compression developed by Apple.
