Thank you, 'your' was for shortness I hoped it could support at least main profile. I have to encode 1080p streams and baseline profile it's not well suited. Regards F

Hi @Ubobrov, thank you very much for all the infos. Very very interesting. About H.264 encoding, what profile types your driver supports? (base, main, high, ...)

After a fresh new complete rebuild and reinstall following a clean procedure I got the same troubles. Giving up for now until I get some grip on the issue. Currently it's just a black box for me. @jernej Thank you for all your support and patience.

I was not aware of that option. My bad. I only had to left out --enable-libopencv because even if installed it cannot be seen. Don't know why. Anyway, after ffmpeg and mpv rebuilt anything changed. > ffmpeg ffmpeg version n4.0.4-0ubuntu0.18.04.1 Copyright (c) 2000-2019 the FFmpeg developers built with gcc 7 (Ubuntu/Linaro 7.4.0-1ubuntu1~18.04.1) configuration: --prefix=/usr --extra-version=0ubuntu0.18.04.1 --toolchain=hardened --libdir=/usr/lib/arm-linux-gnueabihf --incdir=/usr/include/arm-linux-gnueabihf --enable-gpl --disable-stripping --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmp3lame --enable-libmysofa --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librubberband --enable-librsvg --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxml2 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libdrm --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libx264 --enable-shared --enable-v4l2-request --enable-libudev libavutil 56. 14.100 / 56. 14.100 libavcodec 58. 18.100 / 58. 18.100 libavformat 58. 12.100 / 58. 12.100 libavdevice 58. 3.100 / 58. 3.100 libavfilter 7. 16.100 / 7. 16.100 libavresample 4. 0. 0 / 4. 0. 0 libswscale 5. 1.100 / 5. 1.100 libswresample 3. 1.100 / 3. 1.100 libpostproc 55. 1.100 / 55. 1.100 Hyper fast Audio and Video encoder usage: ffmpeg [options] [[infile options] -i infile]... {[outfile options] outfile}...

Thank you, I did a first quick attempt because of little time available, but I was not able to build ffmpeg with so many options. I got troubles installing so many libraries and make them available to ffmpeg. I'll retry later.

After complete rebuild and reinstall of everything it's still not working.

I checked the armbian config-default.conf where the option is empty instead of "yes" INSTALL_HEADERS="" # install kernel headers package Tomorrow I'll rebuild everything and I'll let you know if it's working Thanks and regards

Maybe I have problems on kernel headers.

I had some progresses using 'null'. But it's logging that it's using software decoding.

Yes I have /dev/dri/card0 > ls /dev/dri/card0 /dev/dri/card0 but I don't have any monitor connected. NanoPiNeo doesn't have any HDMI output. Sorry, I wasn't aware that the physical monitor is mandatory. So with my device the only way is to dig into ffmpeg and understand why it's apparently not using the hw accels. I'll post results in case I'll get them. Thank you again Regards F

Thank you jernej, there's no desktop environment at all and I'm running command from the command line. I'm using just the standard megous DEV branch patched with the kernel patches you suggested. I'm already able to run on the same device the VAAPI stack, which is quite limited because it's able to correctly decode only the base profile. From previous posts I got the fact that the ffmpeg way could decode any h264 profiles. Is it right? If so I'm very interested to make it work, because I don't have any idea when the VAAPI stack will be fully implemented. Regards F

Digging a bit more Calling v4l2-ctl --log-status I'm getting the same 'Inappropriate ioctl for device' seen before > v4l2-ctl --list-devices --verbose cedrus (platform:cedrus): /dev/video0 VIDIOC_QUERYCAP: ok > v4l2-ctl --log-status --verbose VIDIOC_QUERYCAP: ok VIDIOC_LOG_STATUS: failed: Inappropriate ioctl for device

Sure, thank you. Read below. What is not clear to me is if your patches still use VAAPI. In that case I've not yet installed (because of compilation errors to solve) libva-v4l2-request as suggested by https://linux-sunxi.org/Sunxi-cedrus libva-v4l2-request The main userspace component that supports the Cedrus VPU driver is the libva-v4l2-request VAAPI backend.
