Phil, it is possible to disable compass/gps if you edit /etc/init.d/usb script in the camera or delete/rename /usr/html/start_gps_compass.php
The limit for the image compression quality with compass/gps enabled may be due to several reasons: 1 - CPU usage by the compass/gps applications 2 - increased size of the data that is copied by the driver with each frame To find out what part is responsible you can let compass and/or GPS be recognize at start up (that would format Exif headers and set amount of data copied with each frame and start the compass and/or gps applications) but then later kill those applications. And see what maximal compression quality you can achieve in that case. If killing application helps, we can try to optimize them (or just make them re-run after several frames). You may also try to kill str (streamer) if you do not need it. Alternative solution would be to add a feature to camogm to watch fro the buffer size and dynamically adjust image quality if the buffer is dangerously low. Unfortunately I just noticed a bug in the software - when you adjust image quality there is a delay between that in the FPGA and in the frame header. I'll work on it. Andrey
