As far as I can see the primary use for MediaStreamTracks in WebWorkers 
is post-processing.  And there are a range of other options that would 
definitely be worth discussing here that would significantly improve 
performance.

e.g.

- access to video frame textures inside shaders without them being 
painted (VideoShader - small change)
- options to access video frames without them being painted to 
canvas/video elements (WebVideo - new API)

I raised these recently at the FOMS workshop.
