It depends on your encoder capabilities. Some of them implements VBR mode,
and will handle this for you. Other have CBR but the bitrate can be adapted
externally. Then you need you own motion filter to measure. Some CODEC like
vaapi/Intel have a very advance method, were you can retrieve the motion
calculated by the encoder. This one isn't integrated into GStreamer
elements yet. It will require vaapi programming for sure.
