There is no reason to have this bug set as REOPENED.

A changeType implementation is a completely different effort. Note it wasn't even in the spec when this original bug was open.

Also, as I explained "An audio/video/text stream can't be reconverted to other type" is a requirement of the spec. Even with changeType, SourceBuffers can't change from video into audio. The number and type of tracks must much, but container and codecs can differ. https://w3c.github.io/media-source/#ref-for-dfn-first-initialization-segment-received-flag-2

Feel free to open a separate bug for a changeType implementation in MSE GStreamer. That is a feature that is in the cooking pot, but to which it's hard to get to while being overwhelmed with bug fixing.
