Hi there,
I have a problem on V4l2 interface of R24.1, I have a HDMI to CSI2 chip on TX1, and we have our own ioctl-based( not Gstreamer ) test routine to evaluate the performance, it stream out at 4k@30fps UYVY format, we always execute the max performance script before running our routine, it can achieve 4k@30fps without any problem when first setting “VIDIOC_STREAMON”, if I stop streaming by setting “VIDIOC_STREAMOFF” and then set back to on, I will never get 30FPS anymore, but 15FPS instead, I can bring it back to 30FPS by fully loading all the 4 CPUs( using load test command “stress” ), I have no idea why CPU draw back its performance, are there any methods to keep CPU running at maximum performance without dynamically change it’s load or frequency. thanks.
Kevin
