Support for stateless codecs and Request API will hopefully be merged for
4.20, and the next step is to discuss how to organize the userspace support.
Hopefully by the time the media summit starts we'll have some better ideas
of what we want in this area.
Some userspace support is available from bootlin for the cedrus driver:
- v4l2-request-test, that has a bunch of sample frames for various
codecs and will rely solely on the kernel request api (and DRM for
the display part) to test and bringup a particular driver
https://github.com/bootlin/v4l2-request-test
- libva-v4l2-request, that is a libva implementation using the
request API
https://github.com/bootlin/libva-v4l2-request
But this is more geared towards testing and less a 'proper' implementation.
I don't know yet how much time to reserve for this discussion. It's a
bit too early for that. I would expect an hour minimum, likely more.
Regards,
Hans
