@aboba FWIW From perspective here tracks added to a `MediaStream` should have the ability to be recorded by `MediaRecorder` in sequence while the `MediaStream` is still `active`. 

One use case is recording multiple media fragments with a single instance of `MediaRecorder` which result in a single `webm` file. 

The above is possible at Firefox using multiple `MediaRecorder` instances (one for each media playback that is recorded) and `MediaSource` https://github.com/guest271314/MediaFragmentRecorder/blob/master/MediaFragmentRecorder.html. 

However, recording a `MediaStream` where the underlying source is a `MediaStream` captured from a `<video>` element still crashes the tab at Chromium https://github.com/w3c/media-source/issues/190.
