[PATCH] media: cedrus: Convert to MPLANE uAPI

Chen-Yu Tsai
2022-11-29T07:45:46Z

The majority of the V4L2 stateless video decoder drivers use the MPLANE
interface.

On the userspace side, Gstreamer supports non-MPLANE and MPLANE
interfaces. Chromium only supports the MPLANE interface, and is not yet
usable with standard desktop Linux. FFmpeg support for either has not
landed.

A fallback route using libv4l is also available. The library translates
MPLANE interface ioctl calls to non-MPLANE ones, provided that the pixel
format used is single plane.

Convert the Cedrus driver to the MPLANE interface, while keeping the
supported formats single plane. Besides backward compatibility through
the plugin, the hardware requires that different planes not be located
too far apart in memory. Keeping the single plane pixel format makes
this easy to enforce.

This has been tested with Fluster. The score remained the same with or
without the patch. This also helps with getting VP8 decoding working
with Chromium's in-tree test program "video_decode_accelerator_tests",
though Chromium requires other changes regarding buffer allocation and
management.
