Reviewed by Jean-Yves Avenard.

AV1 VTB decoder may be sent video frames of varying size through the WebRTC code path.
To properly handle this, we parse each encoded frame to get its input format.
If the input format is different from the current input format, we recreate the VTB session.

Covered by added test.
