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 -" [1] https://github.com/Kwiboo/fluster/tree/v4l2-request
