I also decided to give a try to vulkan: HWAccelIntro – FFmpeg. But it seems like there is no proper vulkan driver, so it uses llvmpipe. But it works. I also found this fork of FFmpeg that introduces v4l2-request hwaccel support, and it SEEMS to work if I launch ffmpeg with -hwaccel drm

@jock hi! Thank you for info. Yes, of course, I would like to give it a try. Appreciate that!

Hello everyone, Thank you for stopping buy and reading this thread. I have Orange Pi 4 LTS with the latest Armbian Jammy image (Armbian_23.8.1_Orangepi4-lts_jammy_current_6.1.50). But I also want to mention that I've tried the same thing on the "official" Ubuntu image from OrangePi website and it was the same. I need to decode and show RTSP video stream, h264 encoded. First of all, I've tried gstreamer with v4l2 codecs. I was using v4l2slh264dec from gst_plugins_bad. This is the only hardware codec in gstreamer for my device (at least available by default) and it worked fine until I started encountering a strange bug when my video getting stuck into 0.5-1 second loop forever. Anyway, I thought that I could bypass this issue by building libav/FFmpeg with v4l2 features and using it instead. However, I couldn't, and this is my problem. I am building FFmpeg from source like this: First of all, I made sure that there is no FFmpeg on my system. Then: sudo apt install libv4l-dev libsdl2-dev -y git clone https://github.com/FFmpeg/FFmpeg.git cd FFmpeg/ ./configure --enable-libv4l2 --enable-libdrm No errors/warnings. h264_v4l2m2m is in "Enabled decoders". make -j6 sudo make install sudo ldconfig ffplay -vcodec h264_v4l2m2m rtsp://192.168.0.125:8554/stream It gives me the following error: If I do not specify v4l2m2m decoder - it works just fine, but with software decoding. Drivers are present: And I have no idea how to fix this issue I will appreciate a lot any help!
