QUESTION
I'm using the video conference implementation source code using webrtc and nodejs.
I'm sending a video from a server to a client. I need to compute the PSNR
of the received video to compute the objective visual quality.
My concerns are:
- how to save the streamed frames at the client, from the video component of HTML5?
- If (1) is achieved, how to map the original frames with the received ones?

Answered 2021-Apr-16 at 11:07Record Audio and Video with MediaRecorder
I solved the problem using MediaRecorder. Using MediaRecorder API, you can start and stop the recorder, and collect the stream data as they arrive.
The MediaStream can be from:
- A getUserMedia() call.
- The receiving end of a WebRTC call.
- A screen recording.
It support the following MIME types:
- audio/webm
- video/webm
- video/webm;codecs=vp8
- video/webm;codecs=vp9
The following demo demonstrates that and the code is available as well
I still have to solve the second concern!! Any idea for mapping the local and remote video frames?
