-known issues:
-
- - negotiation is shite. I don't want to know about any failed
- negotiations or failed prerolls.
-
- - teardown sometimes fails.
-
- - sharing a GL context among a bunch of elements that stomp all
- over it is potential fail.
-
-
-intel driver:
-
- - rendering to texture ignores the color matrix. This causes any
- YUV->RGB conversion to fail.
-
- - YUY2 and UYVY conversions in the driver use the wrong matrix.
