Sorry about that. I was imprecise. Tested HDMI sound this morning and it works perfectly. The 3.5mm jack is completely missing though. Not even listed in the alsamixer UI. As mentioned previously, this is not an issue. I will try the nvme install this week-end.

Got ver 20.02.0-rc1 20200129 on my NanoPc-T4. Things work great: wired ethernet, wifi (with martinayotte's fix), bluetooth, nvme No sound from the native soundcard, but not an issue since I have a USB module for that. Thanks!

Having issues with the NVMe drive with this unified boot process (the FriendlyDesktop image for the NanoPC T4 is able to see the drive, so it is not a hardware issue). I wrote the u-boot-rk3399-tv.img to the SD card, but I am getting: jerryg@arm:~$ dmesg | grep pcie [ 20.489985] rockchip-pcie f8000000.pcie: no vpcie12v regulator found [ 26.398329] rockchip-pcie f8000000.pcie: no vpcie12v regulator found [ 26.925369] rockchip-pcie f8000000.pcie: PCIe link training gen1 timeout!

Interestingly, @Kwiboo's ffmpeg v4l2-request-hwaccel-4.0.4 branch seems to be all about using these new v4l2 features. I will try using that tomorrow. Need to compile his ffmpeg and mpv branches though...

I was actually looking at both encoding and decoding. For decoding, the kernel state can be found here: https://github.com/torvalds/linux/blob/v5.5-rc2/drivers/staging/media/hantro/rk3399_vpu_hw.c#L64 Notice the .fourcc is: V4L2_PIX_FMT_MPEG2_SLICE While GStreamer will expect V4L2_PIX_FMT_MPEG2 (notice the missing _SLICE) Here: https://github.com/GStreamer/gst-plugins-good/blob/66351255f7491a066ac69c49bf6f3bff6d35cd88/sys/v4l2/gstv4l2object.c#L1413 I see similar differences for H264 and VP8 decoding. My guess at this point is that the hantro_vpu driv

Yes, but it seems the hantro_vpu module is a little too barebones at this point in time. Gstreamer will auto-detect what is available, and so far in kernel 5.5-rc2, we only have JPEG encoding supported. Stay tuned for further modules appearing as support improves. jerryg@arm:~$ gst-inspect-1.0 --plugin /usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstvideo4linux2.so Plugin Details: Name video4linux2 Description elements for Video 4 Linux Filename /usr/lib/aarch64-linux-gnu/gstreamer-1.0/libgstvideo4linux2.so Version 1.

Well, `mpv --vo=gpu --hwdec=yes --hwdec-codecs=all -v` shows no HW decoding for a MPEG2 video, so there might still be something missing: Same for a VP8 video. I will have to see if I can get gstreamer to go further.

The support for the Hantro G1 VPU is implemented via video4linux2 (See Collabora's efforts: https://www.collabora.com/news-and-blog/news-and-events/linux-kernel-5.4.html) I don't think vdpau will help. With kernel 5.5, native mpv playback of mpeg-2/VP8/VP9 seems to work well at 24fps, but skips frames at 60fps trying to output thru x11. The OpenGL ES playback is slower (--vo=gpu --gpu-api=opengl --opengl-es=yes), so there might still be work to be done to hand decoded frames to the GPU. I will run a few more tests using youtube-dl.

Thanks @balbes150, the 5.5 eoan works correctly on my nanopc-t4. @NicoD: Fastest way to get bleeding edge Mesa on Ubuntu is to use Oibaf's PPA: https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers
