@jernejdo you mean this patch: https://github.com/LibreELEC/LibreELEC.tv/blob/master/packages/multimedia/ffmpeg/patches/v4l2-request/ffmpeg-001-v4l2-request.patch

I've built a image for this board: https://github.com/amazingfate/armbian-h68k-images, based on 5.10 rockchip legacy kernel, supporting panfrost gpu driver and hardware accelerated Kodi.

@zelda1link3rock3a is not supported by now because my image hasn't get legacy kernel 5.10 support. But I've just supported another rk3568 board hinlink h68k: https://github.com/amazingfate/armbian-h68k-images. I will make support for rock3a someday in the future.

Solved by modifying the code of ffmpeg. I can play 10bit videos now. Thank you for your response @jernej @balbes150

@balbes150yes I've tried both EGL and direct to planel. Direct to plane seems to support more formats.

I've created an issue about 10 bit videos not playable on kodi: https://github.com/xbmc/xbmc/issues/22202. Here is the debug log of kodi: https://paste.ubuntu.com/p/C29gywz4Tg/. We can see "CEGLImage::SupportsFormat - format not supported: NA12". NA12 should come from ffmpeg: https://github.com/JeffyCN/FFmpeg/blob/master/libavcodec/rkmppdec.c#L48. What I concern is why the support list of dma buf format doesn't have NV15, the yuv420 10bit drm format, which should be supported by the rockchip's drm driver: https://github.com/friendlyarm/kernel-rockchip/blob/nanopi5-v5.10.y_opt/include/uapi/drm/drm_fourcc.h#L244. Kodi uses eglQueryDmaBufFormatsEXT to get the supported dma buf format: https://github.com/xbmc/xbmc/blob/master/xbmc/utils/EGLImage.cpp#L225. Anyone knows why egl doesn't support 10 bit drm format NV15? @jernej@Kwiboo@balbes150

Rockchip has released bsp kernel 5.10 for rk356x and rk3588. Since multimedia support is not fully supported by mainline kernel, a legacy kernel would be good if you want h264/hevc hardware decode. To make kodi support hardware decoding, you need: 1, ffmpeg supporting rkmpp. I've packaged it in my ppa: https://launchpad.net/~liujianfeng1994/+archive/ubuntu/rockchip-multimedia, which is based on the patch from https://github.com/JeffyCN/FFmpeg/. 2, kodi built with gles render system, which is also in my ppa 3, a gpu driver supporting gles. For rk356x you can use mainline panfrost driver. For rk3588 you can use panfork-mesa from my ppa: https://launchpad.net/~liujianfeng1994/+archive/ubuntu/panfork-mesa I've tested that kodi can support hardware decoding on both 3568 and 3588. Here is the steps for rock5b to install kodi: 1, download the image I build with panfork-mesa and malig610 firmware: https://github.com/amazingfate/armbian-rock5b-images, and install it on your rock5b. 2, add my rockchip multimedia ppa: https://launchpad.net/~liujianfeng1994/+archive/ubuntu/rockchip-multimedia: sudo add-apt-repository ppa:liujianfeng1994/rockchip-multimedia 3, create a udev rule to enable the permission ofrockchip's mpp device: KERNEL=="mpp_service", MODE="0660", GROUP="video" KERNEL=="rga", MODE="0660", GROUP="video" KERNEL=="system-dma32", MODE="0666", GROUP="video" KERNEL=="system-uncached-dma32", MODE="0666", GROUP="video" RUN+="/usr/bin/chmod a+rw /dev/dma_heap" wirte the above rules to /etc/udev/rules.d/11-rockchip-multimedia.rules 4, install kodi: sudo apt install kodi 5, move kodi from xsession to wayland-session: sudo mv /usr/share/xsessions/kodi.desktop /usr/share/wayland-sessions/kodi-wayland.desktop 6, reboot the board: sudo reboot 7, in the lightdm greeter, select kodi and login 8, After starting kodi, in Settings -> Player -> Videos, enable "Allow using DRM PRIME decoder" and "Allow hardware acceleration with DRM PRIME". And set "PRIME Render Method" to "Direct To Plane" 9, Then you can play h264/h265 8 bit/10bit videos up to 4K. ============Updated on 20230206=================== rockchip-multimedia has become a universal ppa for rockchip legacy kernel. Here is the introduction: https://forum.radxa.com/t/introduction-to-rockchip-multimedia-ppa-for-ubuntu-jammy/14537 I provide a new package rockchip-multimedia-config to do all the system configs such as udev rules, chromium v4l2 devices creation. Just install this package and reboot, you are good to go.

@TaNGSoFT@gounthar Armbian has supported u-boot spi image since its initial support for rock5b. If you are using spi flash image from radxa wiki, you will failed to boot armbian because that is not a GPT image. There are two ways to write the spi flash image from armbian to the spi nor flash: 1, Boot armbian from sdcard or emmc first, and use nand-sata-install to install the u-boot to spi flash. 2, You can download the u-boot deb file from the repo of armbian: https://mirrors.tuna.tsinghua.edu.cn/armbian/pool/main/l/linux-u-boot-rock-5b-legacy/linux-u-boot-legacy-rock-5b_22.08.6_arm64.deb. Extrat it using `dpkg -x linux-u-boot-legacy-rock-5b_22.08.6_arm64.deb`, and find the spi image file `rkspi_loader.img`, and write it to spi flash referring to radxa's wiki: https://wiki.radxa.com/Rock5/install/spi Then use dd or ether to install armbian image to your NVME SSD.

You can play 1080p video with hardware decode using kodi. You have to install a v4l2-request patched ffmpeg and kodi rebuilt with option `-DAPP_RENDER_SYSTEM=gles`. You can see more detailed info from this post: https://forum.radxa.com/t/app-kodi-on-armbian-with-hardware-accelerating-decode/10170

I can play 1080p video using kodi with v4l2-request patched ffmpeg. I can also use command `ffmpeg -hwaccel drm -hwaccel_output_format drm_prime -i bbb_sunflower_1080p_30fps_normal.mp4 -f null -` to decode the video, but I failed to play video using mpv with hardware accel, what am I missing?
