thank you for the clarification.
The fact that you're properly getting a stream with alpha transparency indicates that the issue is not with the particular specification this is repo is about (MediaStream Recording).

The problem here lies with transmission of a video with an alpha channel via WebRTC, which has both codecs and protocols aspects - @aboba can you say if that's something that's achievable today? if not, where would be the right place to bring this up?
