This series aims to make HEVC uapi stable and usable for hardware
decoder. HEVC uapi is used by 2 mainlined drivers (Cedrus and Hantro)
and 2 out of the tree drivers (rkvdec and RPI).
After the remarks done on version 2, I have completely reworked to
patches
split so changelogs are meaningless. I have also drop "RFC" from the
titles.
Version 4:
- Add num_entry_point_offsets field in struct
v4l2_ctrl_hevc_slice_params
- Fix V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS name
- Initialize control V4L2_CID_STATELESS_HEVC_ENTRY_POINT_OFFSETS
- Fix space/tab issue in kernel-doc
- Add patch to change data_bit_offset definition
- Fix hantro-media SPDX license
- put controls under stateless section in v4l2-ctrls-defs.c
At the end fluster tests results on IMX8MQ is 77/147 for HEVC codec.
Dear reviewers,
This series is waiting for your feedback,
I tried several times with the suggested repos for both the kernel and
g-streamer without success getting Fluster to pass any tests on the
imx8mq. I can try again but I likely won't get to it until this
weekend. If I can get it working, I'll test both the 8mq and 8mm.
Thanks a lot for that.
Benjamin
Adam,
You may need to check if h265parse and v4l2slh265dec are available on your board.
I ran gst-inspect to see what showed up with 265 in the name.
# gst-inspect-1.0 |grep 265
libav: avdec_h265: libav HEVC (High Efficiency Video Coding) decoder
rtp: rtph265depay: RTP H265 depayloader

v4l2codecs: v4l2slh265dec: V4L2 Stateless H.265 Video Decoder
videoparsersbad: h265parse: H.265 parser
It appears I have both h265parse and v4l2slh265dec.
fluster check if v4l2slh265dec is working fine with this command line:
gst-launch-1.0 appsrc num-buffers=0 ! h265parse ! v4l2slh265dec ! fakesink
so if one of them is missing it won't work.
gst-launch-1.0 appsrc num-buffers=0 ! h265parse ! v4l2slh265dec ! fakesink

Does this mean I have a wrong version of the kernel and/or incomplete patches?
I double checked the branches.
Kernel:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream.git
branch: origin/HEVC_UAPI_V4
Gstreamer:
https://gitlab.freedesktop.org/benjamin.gaignard1/gstreamer.git
branch: origin/benjamin.gaignard1/gstreamer-HEVC_aligned_with_kernel_5.15
I am still not able to run h.265/HEVC tests.
Hello Adam,
I have updated the following branches with the versions I have used today:
Kernel:
https://gitlab.collabora.com/benjamin.gaignard/for-upstream.git
branch: origin/HEVC_UAPI_V5 only one change in documentation vs version 4 but rebased in v5.18-rc1
Gstreamer:
https://gitlab.freedesktop.org/benjamin.gaignard1/gstreamer.git
branch: origin/benjamin.gaignard1/gstreamer-HEVC_aligned_with_kernel_5.15 updated on the latest GST main branch
I hope this will work fine this time.
I wish I had better news for you:
dmesg shows the hantro driver is being loaded:

Fluster reports:

Still the same error about non supported control ?
