[mpeg4_v4l2m2m @ 0x5602c25bb740] can't configure encoder
It looks like it's trying to use hardware accelerated encoding, but then
doesn't find the hardware. Assuming you have x264-libs installed from
rpmfusion, try adding "-vcodec libx264" to the command.
Try running "ffmpeg -encoders | grep 264" to see what you have
available. I don't know if the openh264 package provides a usable
encoder. You might have to get one from rpmfusion to do encoding.
