Linux system, USB camera use V4L2 gathers the image of YUYV format on PC using QT Creator and QTOPIA tools can gathers the image of perfection, however, cross-compilation generated after arm version of the program, running into the arms of the friendly Tiny210 or mini2440 are the stripes image is obtained? Ask everybody, this is where I wrong? Run on the PC, the program is no problem, why embedded arm operation error?

CodePudding user response:

Brush figure could be deal with the problem, can try to save an image, whether single file is normal,
The other, in the embedded usb camera device file is not necessarily the/dev/video0

CodePudding user response:

I try to keep the original data stream, can see the full image on the PC, after transplanted into the arm, the image becomes a striped, ambiguous

CodePudding user response:

The original data mean yuyv data? If it is possible on arm system does not support yuyv data formats, but the basic support yuyv
