Dear all, This is v5 of the series adding VP9 profile 0 decoding to rkvdec. All feedback from v4 should be addressed, there's just one thing I did not address: ref_frame_sign_biases in the uAPI. The userspace tool I'm using [1] apparently doesn't need it or the default hwreg value for it is capable of decoding the bitstreams I used on the driver, so I don't really have a use-case to change and test that. :) Considering the uAPI is a work in progress and expected to be modified, ref_frame_sign_biases can be added later with others which might be required to enable more functionality (for eg profiles >= 1). Series tested on rk3399 and applies on next-20201030. [1] https://github.com/Kwiboo/FFmpeg/tree/v4l2-request-hwaccel-4.2.2-rkvdec Changelog --------- v5: * Drop unnecessary OUTPUT buffer payload set in .buf_prepare. * Drop obsolete .per_request ctrl flag * Added new vp9 ctrls to v4l2_ctrl_ptr * Fix pahole detected padding issues * Send userspace an error if it tries to reconfigure decode resolution as v4l2 or rkvdec-vp9 backend do not support dynamic res changes yet * Allow frame ctx probability tables to be non-mandatory so users can set them directly during frame decoding in cases where no defaults have been set previously (eg. ffmpeg vp9 backend) * Some comments and documentation clarifications * Minor checkpatch fixes v4: * Drop color_space field from the VP9 interface. V4L2 API should be used for it. * Clarified Segment-ID comments. * Moved motion vector probabilities to a separate struct. v3: * Fix documentation issues found by Hans. * Fix smatch detected issues as pointed out by Hans. * Added patch to fix wrong bytesused set on .buf_prepare. v2: * Documentation style issues pointed out by Nicolas internally. * s/VP9_PROFILE_MAX/V4L2_VP9_PROFILE_MAX/ * Fix wrong kfree(ctx). * constify a couple structs on rkvdec-vp9.c Boris Brezillon (2): media: uapi: Add VP9 stateless decoder controls media: rkvdec: Add the VP9 backend Ezequiel Garcia (1): media: rkvdec: Fix .buf_prepare .../userspace-api/media/v4l/biblio.rst | 10 + .../media/v4l/ext-ctrls-codec.rst | 550 ++++++ drivers/media/v4l2-core/v4l2-ctrls.c | 239 +++ drivers/media/v4l2-core/v4l2-ioctl.c | 1 + drivers/staging/media/rkvdec/Makefile | 2 +- drivers/staging/media/rkvdec/rkvdec-vp9.c | 1577 +++++++++++++++++ drivers/staging/media/rkvdec/rkvdec.c | 72 +- drivers/staging/media/rkvdec/rkvdec.h | 6 + include/media/v4l2-ctrls.h | 5 + include/media/vp9-ctrls.h | 486 +++++ 10 files changed, 2942 insertions(+), 6 deletions(-) create mode 100644 drivers/staging/media/rkvdec/rkvdec-vp9.c create mode 100644 include/media/vp9-ctrls.h -- 2.29.0
