Hello,
when I use the following command in Raspberry Pi 4 model B, I am getting
only 8 fps for 1080p resolution.
*ffmpeg -use_wallclock_as_timestamps 1 -t 60 -i /dev/video0 -c:v
h264_v4l2m2m -b:v 8M -maxrate 2M -vsync 2 -bufsize 4M -r 30 -s hd1080
-pix_fmt yuv420p -g 30 -qmin 20 -qmax 50 output_10
Please post the complete command output with all the options and error
messages, otherwise it's only guessing (see section 6 of
https://ffmpeg.org//mailing-list-faq.html).
z!

Save some hassle and get a 7.x version. (Or at least 6.x.)

First thing is to try a modern version of ffmpeg, that one is positively
ancient and pretty much unsupported.
Later,

But what is full command line you use (the ffmpeg parameters to the
device)? I do not see it being posted.
