No plan at the moment. But I'll let you know before starting something to
avoid duplication. But I'll check regularly for regressions with what just
landed and with ChromiumGStreamerBackend.
I'll try first to finish st/va chunk decoding with nouveau driver, Last
blocker was a pb with h264. Maybe some plan to experiment mesa-st/omx +
Tizonia + gst-omx on desktop, will see if I have some time to spend there.
