Get actual playtime of webrtc stream

I am streaming video from gstreamer to the rtsp, convert it to the webrtc and show the video in the website. I need to know what is the time from the beginning of the stream to synchronize with some additional metadata.

When I connect to the stream 10 seconds after the streaming started for example, I need to know that the delay between start and my delay is exactly 10 seconds.

How can I get such information?

You have two choices.

  • Insertable Streams and insert metadata with each frame. I would use a identity element and modify in the handoff.

  • requestVideoFrameCallback this allows you to get exact timing information. presentationTime is probably what you want, but other values might be useful.
