"USB Video Class " MJPEG to YUY2

[Anonymous]

I've changed "USBVideoClass" example from MJPEG to YUV(from subtype : VS_FORMAT_MJPEG to Subtype : uncompressed format)

The descriptors are originally configured to stream MJPEG images stored in "glUVCVidFrames[]" structure which in cyfxuvcvidframes.c. And now i have chaged frames to yuy2 format. I have modified ‘cyfxuvcdscr.c"。The device is successfully recognized by host but cannot begin streaming any data. My video frames is not visible in AMCap. I have EZ-USB® FX3™ Development Kit (CYUSB3KIT-003), only black screen is displayed.

I don't have cammer.Could you help me? Thank you!

Hi,

--Please go through the below-attached source file, which speaks about 640X480 resolution,16 bits per pixel and hard-coded yuy2 data format.

The attached example firmware works USB 3.0, USB Full Speed and USB Hi-Speed.

--Please share the error UART Debug prints.

Hello, please find the debug print image and SDK debug window image.

Hi,

The "no source available" message would appear if you try to step into a function given by the SDK as the source code for that isn't given out.

Try putting a breakpoint in the main() function or in the app thread's entry function and see if the breakpoint is hit.
