@alexey, if i remember correctly, the problem was about getting a stream from PC, so a remote stream, and then plug it in web audio. For video, I'm pretty sure it is even less advanced than audio.

For example, you can open mp3 file and send it together with microphone stream via PeerConnection or without mic stream as well. Chrome has some other issues related to that which prevent client conference mixing, but Chrome team knows about that and will fix it in the future. In Firefox it's worse - WebAudio isn't connected to WebRTC yet, so you can't send a stream from WebAudio to PeerConnection there, I filled the bug and Mozilla team knows about the problem, but it has rather low priority at the moment. > > Alexey > >> On Jan 16, 2014, at 3:53, Rob Manson <robman@mob-labs.com> wrote: >> >> Hey Justin, >> >> thanks for the summary...makes it much easier to make sure I'm not re-raising something I missed in the "long" threads 8) >> >> I'd also like to add that "there's no way to add programmatically generated streams to peer connections".

It would also be useful to be able to add post-processed streams (or probably more accurately MediaStreamTracks e.g. use face tracking to mask a persons face, or use object detection to highlight a specific object, etc.). At the moment the only way to send this data to the remote client is via another channel (e.g. DC or WS)...and sync'ing is definitely an issue there. >> >> For example we would definitely like to be able to share the Augmented Web video streams that we can now create. >> See one example here http://youtu.be/OJHgBSRJNJY >> >> This also goes for Web Audio API generated audio tracks too. >> >> NOTE: The generation of these streams/tracks is obviously outside the webrtc spec scope. >> >> roBman >> >> >>> On 16/01/14 10:18 AM, Justin Uberti wrote: >>> Thanks to everyone who posted about what is missing in WebRTC.
