[mediacapture-record] Describe more precisely the handling of disabled tracks (#199)

youennf has just created a new issue for https://github.com/w3c/mediacapture-record:

== Describe more precisely the handling of disabled tracks ==
The spec currently says:
If any Track within the MediaStream is muted or not enabled at any time, the UA will only record black frames or silence since that is the content produced by the Track.

While the intent is clear in terms of rendering of the generated data, it is not clear what the encoder should do. webrtc-pc states that one black video frame should be sent per second, given webrtc transmission might be lossy. No audio is sent at all.

It would be nice to describe what should be done more precisely for MediaRecorder. Given recording is not lossy, a single video black frame might be sufficient to record for instance.
