Oct 9, 2015 at 12:23 | comment | added | dhruvvyas90 | @user3585723 Regarding 30 % usage, capture might be using single thread and hence other cores would be sitting idle, I don't know internals of how capture works but that's the most likely reason. If I remember correctly, I used to get 100 % CPU usage on Rpi 1 and BBB. | |

Oct 9, 2015 at 12:19 | comment | added | ssinfod | I tried the same webcam (Lifecam HD-3000) on my Ubuntu 14.04 and I got 30 fps at 1280x1024. | |
Oct 9, 2015 at 12:18 | comment | added | ssinfod | OK, but the CPU is running only at 30 %. Something seems not right... I will look into the USB bandwidth. | |
