Dear Oliver, I?ve done some tests with the CAM reader from Digital Devices based on Sony CXD2099 chip and I noticed some issues with some CAM: * SMIT CAM : working fine * ASTON CAM : working fine, except that it's crashing quite regularly * NEOTION CAM : no stream going out but access to the CAM menu is ok When looking at the CXD2099 driver code, I noticed the CAM clock (fMCLKI) is fixed at 9MHz using the 27MHz onboard oscillator and using the integer divider set to 3 (as MCLKI_FREQ=2). I was wondering if some CAM were not able to work correctly at such high clock frequency. So, I've tried to enable the NCO (numeric controlled oscillator) in order to setup a lower frequency for the CAM clock, but I wasn't successful, it's looking like the frequency must be around the 9MHz or I can't get any stream. Do you know a way to decrease this CAM clock frequency to do some testing?
