TAG:
"format extension" suggestion that does not have to go into the main
spec, because it could be added as separate spec
https://github.com/cellar-wg/matroska-specification/issues?q=is%3Aissue+is%3Aopen+label%3A%22format+extension%22
"format addition" something that has to go into main specification.
https://github.com/cellar-wg/matroska-specification/issues?q=is%3Aissue+is%3Aopen+label%3A%22format+addition%22
* As the WebM will not be defined, remove all of the WebM specific stuff.
* MCR suggests removing it from the Matroska document, and leave the
history for others. * MB: DivX is also not part of Matroska. Also
concerned about how the Matroska project presents the WebM/DiVX vs core
Matroska elements. The spec will be huge, so take things out.
* define how to add unpredictable data to the Matroska, so we could track
things that are added. Not just WebM, but also a libmotrsaka as well. *
extension data would be on their own lines, and revision history would be
clearly.
6. Any other business.
