Hi all, I'm trying to hardware encode a h264 file on my bananapi with an allwinner A20 SOC. I get a .h264 file that has a size of 0 bytes. I use the following source: https://github.com/danielkucera/FFmpeg/tree/cedrus264 configured in the following way: ./configure --prefix=/usr --enable-nonfree --enable-gpl --enable-version3 --enable-vdpau --enable-libx264 --enable-libmp3lame --enable-libpulse --enable-libv4l2 running with the following command line: cedric@bananapi:~/FFmpeg$ ./ffmpeg -fflags +igndts -f v4l2 -input_format mjpeg -s 1280x720 -i /dev/video0 -pix_fmt nv12 -c:v cedrus264 output.h264 ffmpeg version N-86245-gcd67ff8 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.0 (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9) 20160609 configuration: --prefix=/usr --enable-nonfree --enable-gpl --enable-version3 --enable-vdpau --enable-libx264 --enable-libmp3lame --enable-libpulse --enable-libv4l2 libavutil 55. 63.100 / 55. 63.100 libavcodec 57. 96.101 / 57. 96.101 libavformat 57. 72.101 / 57. 72.101 libavdevice 57. 7.100 / 57. 7.100 libavfilter 6. 90.100 / 6. 90.100 libswscale 4. 7.101 / 4. 7.101 libswresample 2. 8.100 / 2. 8.100 libpostproc 54. 6.100 / 54. 6.100 Input #0, video4linux2,v4l2, from '/dev/video0': Duration: N/A, start: 66666.522955, bitrate: N/A Stream #0:0: Video: mjpeg, yuvj422p(pc, bt470bg/unknown/unknown), 1280x720, 30 fps, 30 tbr, 1000k tbn, 1000k tbc File 'output.h264' already exists.
