For the mp4 container we only support the h.264, AAC and MP3 codecs, so passing PCM audio would be the problem. You'll have to encode the audio from the rtp stream if you want it to be playable in the browser. We limit the formats we support as much as possible to reduce testing and maintenance costs, and to encourage adoption of compatible files. Firefox uses codecs available on each platform, so there will be some variation in the details of what's supported, but you can trace the support decisions in the source code starting with the DecoderTraits object. http://dxr.mozilla.org/mozilla-central/source/content/media/DecoderTraits.cpp#376 Hope that helps, -r _______________________________________________ dev-media mailing list [email protected] https://lists.mozilla.org/listinfo/dev-media
