I want to streamming media data throught 2 android devices. I used this example : https://github.com/pchab/AndroidRTC and i did it. In this example, they used 2 lib android: libjingle_peerconnection and socket.io_client. My problem is when media data is streamming, i can not save it as mp4. Please check my question in here :http://stackoverflow.com/questions/30685276/how-do-record-media-stream-data-as-h-264mp4-in-webrtc-android Sorry for my english

Ok. Mp4 is a container format . Mp4parser can package supported formats/codecs in MP4 containers . What kind of codec is used for webrtc?

VP8 for video and Opus for Audio

Ok, now we are getting closer! Afaik there is no specification that allows you package VP8 and/or Opus in MP4 containers. Therefore the mp4parser library won't be able to help you.

according to http://opus-codec.org/docs/ - http://opus-codec.org/docs/opus_in_isobmff.html it should be possible to package opus in mp4
