Move control track related content in a separate document #461
Conversation
Is this really only for Control Tracks? A good player could read the ChapterTrack and uses only the listed tracks (ordered chapters are required). |

It's true that the
But just like control track it's not currently used so I'd rather move it out for now than delaying the specifications for something noone has ever used. Neither vlc nor libavformat support these elements. |

BTW, the specs contained as many features as we could think of, even not correctly/properly defined because the idea was to have as much "prior art" as possible. So if anyone tries to patent a new feature they can't because we already thought of it. Even the chapter codecs fall in this category except it got to a proof of concept in VLC. We don't need these extra parts in the v1 to v4 specs which is meant to specify what is currently used in Matroska. |

Rebased after the #342 merge which had more text based on now-moved elements. As a result some tables and text have been simplified. |
This is an advanced feature currently not used that will work better with Control Tracks and more advanced tracks selection than the one currently defined in the Matroska Specifications.
Since it's not used and only usable by control tracks, we can move it there.
There is no other way to toggle it and it should not be mentioned in the main spec which doesn't deal with control tracks.
There is no other way to toggle the flag and it's not defined anywhere else. it's unlikely to be used anywhere, unlike ChapterFlagHidden which can be used to have chapter codecs invisible to the user.
It was meant to use Control Tracks and is irrelevant in the main specs.

Rebase after #469 merged. |
The new document is in a dirty state and we may never use it. But it's a way to clean the Control Track reference (an under specified and unused feature) out of the main document.
Fixes #456
