SOLVED veye_raspivid -b param ignored
I have a Veye IMX307 camera, it's working fine, but there is a problem with vide recording.
The -b parameter (for the bitrate) seems to be ignored by the veye_raspivid program, I always get pretty much the same bitrate (depending on the camera view and how I move it. That is more or less variable bitrate)..
Any way around it? Or is there another parameter or i2c setting I need to send to camera to have the bitrate param work?

-b parameter is effective.
The default value is 17Mbps which is pretty big value for 1080p@30fps stream.
state->bitrate = 17000000;
The H.264 encoder of the chip will be encod the video below this value. If your scene is not complex, the actual bit rate of the encoding may be much smaller than this.
I'll tell you a test method. You can -b1000000, configure to 1Mbps, you can see the obvious difference in file size.
