Description
While input_format can be set to h264 there is no way to set the bitrate for a webcam.
The bitrate for the camera in question can be set with "v4l2-ctl --set-ctrl video_bitrate=300000"
How to reproduce:
% ffmpeg -f video4linux2 -input_format h264 -video_size 1280x704 -i /dev/video0 ... ffmpeg version 3.2.5-1 built with gcc 6.3.0 (Raspbian 6.3.0-18+rpi1) 20170516
