| 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. | |
