Official quickblox documentation is very limited in any details for working with local/remote media streams. I could not find any example /documentation on :
how to extract remote media stream from the session in order to work with the streamed remote video and audio tracks. I would like to extract the video/frames and audio from the session (the opponent remote stream) to further process (save image, or record the stream data)
how to change the source for the local stream from mic/camera to e.g. a stored video or various streams. I would like to send for example a pre-recorder message or video in case of busy opponent.
Any idea, if it can be done by extending any of the Quickblox libraries/classes, as it seems there is no public built in direct method or support for working with the streams?
