2. xtra reading

The commands for the camera module are included as part of the raspberrypi-firmware package - which is installed by default.

-------------------------------------------------------------------------------

The V4L2 driver by default only allows video recording up to 1280x720, else it glues together consecutive still screens resulting in videos of 4 fps or lower.

Adding the following options removes this limitation:

/etc/modprobe.d/rpi-camera.conf

options bcm2835-v4l2 max_video_width=3240 max_video_height=2464

3. testing
