[matroska] Add alaw/mulaw audio support
Last modified: 2011-04-05 12:30:50 UTC
matroskamux/demux support a wide range of audio/video codec would be useful to add support for mulaw/alaw audio codec too, both are in gst-plugins-good. Actually gstreamer support mulaw/alaw only in avimux/demux
There seems to be no official mapping for alaw/µlaw in Matroska: http://matroska.org/technical/specs/codecid/index.html Once there is one we can add support for it. Could you contact the Matroska guys and ask your an official mapping?
sent an email to contact@matroska.org with the request, thanks Nicola
Here is the reply from Steve Lhomme "Hello Nicola, If it's supported in avimux/demux then it can be supported in Matroska via A_MS/ACM. Steve" http://lists.matroska.org/pipermail/matroska-devel/2011-April/004032.html
