Hi everyone, I have an issue using ffmpeg and h264_v4l2m2m encoder/decoder with the IMX8QM. I can encode and decode a file without error, but the output video is green when encoding and completely messy when decoding. Here are the commands that I am using: Encoding:
ffmpeg -f rawvideo -pix_fmt nv12 -s:v 1920x816 -framerate 30 -i my_file.yuv -c:v h264_v4l2m2m my_file.h264 Decoding: ffmpeg -c:v h264_v4l2m2m -i my_file.h264 my_file.yuv I also tested with the v4l2 codec of gstreamer and I can encode and decode without problem. Do you have any idea of what could be the issue ? Did someone has ever tested the hardware encoder/decoder of the IMX8QM with ffmpeg ? I saw that the IMX8QM hardware decoder outputs a specific tiled format, that's maybe the reason why the output video is messy. But at least the encoder should be ok, right ? I am using a linux-imx version 5.4 and ffmpeg version 5.1.1 I also tried the encoder/decoder drivers of the 5.15 imx kernel version with the same results.
