Hello Everybody,
I am following the sprue66d.pdf for using the DVEVM with DVSDK_1_30_00_40
But it fails saying
*******************************************************************************
Encodedecode demo started.
Encodedecode Error: Failed FBIOPUT_VSCREENINFO on /dev/fb/3 (Invalid argument)
Encodedecode Error: Failed ioctl FBIOPUT_VSCREENINFO on /dev/fb/0

Total I-frames: 0, P-frames: 0, B-frames: 0, IDR-frames: 0 rejected: 0
*******************************************************************************
on further investigation we found that kernel itself was having some issues
opening the video port.
following is the part of dmesg;
