Thanks for the info @lex. I have mmp working with gstreamer. The ioctl segfault issue was the arhitecture flags for the compile we're set to unknown. I set it manually to armv7. I am not sure if that's optimal for the NanoPC-T4. It works, but audio is slightly out of sync. I broke Bluetooth support. It was working fine with the rfkill , hciattach userspace hack. I updated before the mmp build.

Figured out what caused the segfault. gst123 now plays mkv files at 1080p. The apt-update/apt-upgrade appears to have broken bluetooth. Before the update the video was playing , audio through a bluetooth speaker. The audio was out of sync.. I'll try a anduse and audio cable. Bluetooth .. I am looking at kern.log now to figure out what's going on.

[ 1327.109430] Bluetooth: hci0 command 0x2005 tx timeout [ 1329.113391] Bluetooth: hci0 command 0x200b tx timeout [ 1331.117400] Bluetooth: hci0 command 0x200c tx timeout [ 1418.207334] Bluetooth: hci0: Frame reassembly failed (-84) [ 1418.207393] Bluetooth: hci0: Frame reassembly failed (-84) [ 1418.207444] Bluetooth: hci0: Frame reassembly failed (-84) [ 1418.207495] Bluetooth: hci0: Frame reassembly failed (-84) [ 1418.207581] Bluetooth: hci0: Frame reassembly failed (-84)

ok.. gstreamer with mpp support worked for 20 seconds! Video was smooth and then ioctl errors followed by a segfault. I was testing with the nightly build I switched to the development kernel and KABOOM NVME root was not mounted. I attempted to boot off an install sd , mount the emmc and nvme and do a chroot, roll the kernel back. Didn't work. I am installing again with the stable kernel, armbinan 5.65 now to get a working board before I quit for the night. MPP with a gstreamer vaapi plugin, test with gst123 and a mkv video file worked for 20 seconds. Invalid ioctl command follwed by a segfault. When it worked the video was good!

I couldn't build gstreamer-rockport-extra CC libgstrkximage_la-rkx_kmsutils.lo rkx_kmsutils.c:41:5: error: ‘DRM_FORMAT_NV12_10’ undeclared here (not in a function); did you mean ‘DRM_FORMAT_NV12’? { DRM_FORMAT_##fourcc,GST_VIDEO_FORMAT_##fmt } I have libdrm-dev installed. Do you know what header file I need ?

When I get a change I need to edit the systemd script. For now I created a startbluetooth script in /usr/local/bin #!/bin/bash rfkill unblock bluetooth hciattach /dev/ttyS0 bcm43xx I added the script to my XFCE4 startup scripts. The right way to do it is update the systemd script that brings up bluetooth. I've just been so busy trying to get VPU working.

I'll take a another look at the nightly build, vpu support was ther when I looked but not for the rk3399. I'll definitely give the BSP kernel build a try Thanks!

VPU hardware encode/decode appears to not work on the NanoPC-T4. I know it's a WIP. If there is a Post Installation Procedure I could do that would work for me.

I tested with the FriendlyARM Linux 18.04 image. glmark2-es scored a 54, but VPAU does not work. I'm reinstalling Armbian Nightly now. I'll configure for fbdev. So you point me to the documentation for Rockport VPU configuration ? The latest Rockchip RK3399 Kernel posted in github does not build properly. Duplicate Declarations.. lots of code to fix.

I understand that the NanoPC-T4 is a work in progress. Is there a timeline for each board posted, or at least a dashboard where I can see if I'm not duplicating work ? Here's the reason why Video Acceleration is as fast as it can be: 3279.942] (II) glamor: EGL version 1.4 (DRI2): [ 3279.942] EGL_MESA_drm_image required. [ 3279.944] (EE) modeset(0): glamor initialization failed I am running the nightly release, I did and apt update, upgrade. I just see midgarud_base.ko loaded. Apprently there are no xorg DRM modules available. It's a WIP so.. possibly it will be available soon. I'm going to install FriendlyARM's Bionic Beaver to see how that is. I'll post what I find.

DAMN! ARM Devlopers cut off access to some of the source code that I need: http://opensource.rock-chips.com/wiki_Graphics No access to UMPLOCK

I still have some work to do. The score was only 24. But I was compiling away on the box all day. I've got a 240GB NVMe on it so developing code on that board isn't too bad at all. I built the latest Plex Media Player, The latest MPV.. and experimenting with the Mali GPU Open Source kit. It's too bad that that the Full Mali Development kit is closed. I bought this board because it has a Mali T860, but I can't take full advantage of it. What a bummer. I'm Actually pulling Panfrost from GIT. I really don't want to work with code that's not 100% opensource. It appears that Panfrost and MPP is ready to use. I'll update the forum with my progress.

I've got bluetooth working flawlessly. OpenGL works fine, Plex Media Server works , SONICC, RADARR all performed well, I built the latest and greatest Plex Media Player. A attempted to get VDPAU acceleration working. I'm running the nightly build with the nanopc-t4 overlay. Just about everything works. video playback works with GL accelleration but VDPAU is needed for mkv files. I installed the vdpau mesa support, and tried the libvdpau-sunxi1 driver. Is there anyone else working on something similar ? vdpauinfo display: :0.0 screen: 0 Error creating VDPAU device: 25

Ma, Thanks for the link! You posted a real easy userspace workaround! I just run rfkill unblock bluetooth, and hciattach /dev/ttyS0 bcm43xx in a startup script. Everything works. Bluetooth keyboard,mouse, audio When my MediaCenter is finished I will pair my old NVIDIA Shield remote with it. The older remotes were bluetooth You post was a big help.

That link you posted looks interesting. When I get home I'm going to give a userspace work around a shot

Hi, I am almost done building my replacement for my NVIDIA Shield! (USB ports that were attached to media storage are fried). I am amazed at how well the NanoPC-T4 performs. I downloaded Armbian even though the board status is "Work in Progress" I wanted to see how well it's coming along. Great Job! I was so impressed with this board that I'm building a Development Environment for it. I just ordered my usb - to -ttl Do you know when BT will be ready ? Is it enabled in the experimental branch ? I noticed the bluetooth kernel module is loaded, it just doesn't enable correctly.. rfkill eventually turns power off, at least that what I see in my logs anyway.
