Slow camera acquisition with Debian Jessie

Hi all!

I am using the V4L2 libraries to capture frames from my 16 bit grayscale USB camera. This worked fine on Debian 7.8. However, I recently flashed my board to the Jessie image recently posted on the beaglebone website (Debian 8.2). Oddly enough, data acquisition takes about 3 times longer now. I’m also getting a lot of dropped data in the frames that I capture. I’m using the same libraries, the same code, and the same camera settings. Anyone have any idea what could be wrong?

Does this help?

sudo cpufreq-set -g performance


Hey Robert, thanks for the reply. I should have mentioned that I already set the cpu frequency to 1000Mhz. If you have any other suggestions though, I’d be all ears.
