Hi all, I have a bananapi, running Armbian 5.38. I have done the following steps to compile ffmpeg: git clone https://github.com/chwe17/FFmpeg-Cedrus.git cd FFmpeg-Cedrus/ ./configure --prefix=/usr --enable-nonfree --enable-gpl --enable-version3 --enable-vdpau --enable-libx264 --enable-libpulse --enable-libv4l2 make -j 2 sudo make install Now i try to capture and encode video from my webcam: cedric@bananapi:~$ ffmpeg -i /dev/video0 -c:v cedrus264 -b:v 1000k -vewait 1000 -f h264 test.h264 ffmpeg version git-2018-03-24-e785140 Copyright (c) 2000-2014 the FFmpeg developers built on May 4 2018 16:31:39 with gcc 5.4.0 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.5) 20160609 configuration: --prefix=/usr --enable-nonfree --enable-gpl --enable-version3 --enable-vdpau --enable-libx264 --enable-libpulse --enable-libv4l2 libavutil 54. 6.100 / 54. 6.100 libavcodec 56. 0.101 / 56. 0.101 libavformat 56. 2.100 / 56. 2.100 libavdevice 56. 0.100 / 56. 0.100 libavfilter 5. 0.102 / 5. 0.102 libswscale 3. 0.100 / 3. 0.100 libswresample 1. 1.100 / 1. 1.100 libpostproc 53. 0.100 / 53. 0.100 /dev/video0: Invalid argument Then I uninstall and reinstall ffmpeg from armbian, so I can test if my webcam itself is to blame.
