Low-Light HD USB Camera

Hi,

we are looking into streaming video from the new Low-Light HD USB Camera over a 4g connection during an inspection, and wondered if it was possible to change the settings in the h.264 encoder in the chip? We want to get a stream with lower bitrate. Currently we get a bitrate of approximately 10 Mbps independent of the settings we set in gstreamer.

Yes it is possible. I have been using v4l2-ctl to do this.

Check this topic How to adjust compression on new HD cam?.

We can set the settings for resolution, framerate and so on, but it seems like the onboard h.264 encoder has a target bitrate on 10 Mbps. So we get the same bitrate at 1080p high fps as we get with e.g 720x480 at low fps. As far as I can see it is not possible to access the encoder settings in v42l-ctl? Or is it?
