Subject: Re: [PATCH v2 0/3] Add hantro g1 video decoder support for RK3588

Thanks for your test with fluster. I also tested on my rock-5b(rk3588)
and orangepi-3b(rk3566) which are sharing the same hantro g1 ip. I am
running on ubuntu jammy so I'm using gstreamer 1.20.1

rk3566 and rk3588 are sharing the same results:
JVT-AVC_V1 test suite with decoder GStreamer-H.264-V4L2SL-Gst1.0:
  Ran 112/135 tests successfully.
JVT-FR_EXT test suite with decoder GStreamer-H.264-V4L2SL-Gst1.0:
  Ran 27/69 tests successfully.
VP8-TEST-VECTORS test suite with decoder GStreamer-VP8-V4L2SL-Gst1.0:
  Ran 59/61 tests successfully.

H264 decoder test has less test case passing. I think that's because
of my low gstreamer version. If you have a rk356x board I guess you
will get the same result as rk3588. That should be the mainline support
status of hantro g1 decoder.

For ffmpeg at the moment fluster doesn't support v4l2-request decoder.
I tried Kwiboo's fork[1] but failed to pass tests with decoder
FFmpeg-H.264-V4L2-request. I can decode video with ffmpeg command like:
"ffmpeg -benchmark -hwaccel drm -hwaccel_output_format drm_prime -i Big_Buck_Bunny_1080_10s_30MB.mp4 -f null -"
