The track view allows users to "delete" tracks if there are multiple tracks in the event. However, it would be nice if the track view would allow to remove only the video or only the audio from a track. For example, you might want to remove the video from a presenter track if the presenter does not want to appear in the recording, but keep the audio from the track.

This feature was present in the old editor. As far as I know it is not present in the new editor due the feature being bugged in the backend. Meaning this issue is not "just" frontend work, but will likely require somewhat extensive work in the backend.

This is a common use case at our institution. We have a lot of dual stream recordings and users sometimes want to publish just the presentation track or even just the audio without the video.

Perhaps this discussion about track selection in the old editor might be of interest:

Split track selection to video and audio selection
b6c0b9e 
In the "Tracks" view, instead of de-/selecting the whole track,
the video and audio streams can be de-/selected individually.
At least one video stream must remain selected. All audio streams
can be deselected. If the audio stream is marked as unavailable,
it cannot be de-/selected.

Shows the waveform from the timeline for a graphical representation
of the audio stream. However, there will only be one waveform
generated for the timeline, so in case of additional tracks a
placeholder image will be shown instead.

Resolves opencast#1009. opencast#1009 also mentions potential issues in the backend,
while this PR only addresses the frontend. From my limited testing
the backend seems fine when using the default community workflows
(no errors, the correct streams get published). If there are any users
around that are still using the track selection feature in the old
editor, and that are aware of any backend issues, please do tell me
about them.
