dvsdk-demos on beagleboard xm

Hi, all. I have problems when running dvsdk-demos in BBXM. First of all, based on what the website(http://sourceforge.net/projects/dvsdkbbxm/files/DVSDK-4.01%20for%20BeagleBoard/) says, I have the dvsdk of beagleboard-xm. After I boot, I came cross the problem like this.

root@beagleboard-dvsdk:/usr/share/ti/dvsdk-demos# ./encode -o

Encode demo started.

Failed to open /sys/devices/platform/omapdss/display2/enabled for writing.

However there is no …/display2 direction in the filesystem. Should I rectify the uboot parameters in uEnv.txt? And another question is whether the encode demo can capture images via usb webcam or not?

Or like follows:

root@beagleboard-dvsdk:/usr/share/ti/dvsdk-demos# ./decode -v HistoryOfTI-480p.264 -O dvi

Decode demo started.

BUT there were no images or video in the screen.

So this problem has bored me for a long time. Could someone give me some advice? Thanks a lot.

Hi,I also face the same problem, did you successfully complete it?I find that encode demo in dvsdk_dm3730-evm_4_01_00_09_setuplinux do not support camera,only suport s-video.
Thanks a lot.
