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
