--- Comment #41 from Olivier Crête <olivier.crete at ocrete.ca> ---
For all formats that are not linear and not the Samsung 64Z32 one, content of
the memory is pretty much opaque. And using capsfeatures & a custom meta makes
negotiation debugging a pain. I think it would be easier to just add a new caps
like "video/x-drm, format=(string)fourcc-from-drm_fourcc.h, modifier=(uint64),
width=, height=, framerate=".. Using video/x-raw means that we would want to
implement support for them in GstVideoInfo, but that's pretty much pointless if
the content is otherwise opaque.
