Hi,
The problem here is not about multiple formats but about Y16/Y8 format. Please see

Hi,
Can you please try YUY2 GUID just for compliance test. It is given below:
0x59,0x55,0x59,0x32, /* GUID used to identify streaming-encoding format: YUY2 */
0x00,0x00,0x10,0x00,
0x80,0x00,0x00,0xAA,
0x00,0x38,0x9B,0x71,
Regards

Checked it... CV test fails even with multiple format descriptor with MJPEG too
Format descriptor 1 - MJPEG (subtype -0x06)
Format descriptor 2 - MJPEG (subtype -0x06)
Uncompressed format descriptor 3 - YUY2 (subtype 0x04)
Whereas,
Format descriptor 1 - MJPEG (subtype -0x06)
Uncompressed format descriptor 2 - YUY2 (subtype 0x04)
Format descriptor 3- MJPEG (subtype -0x06)
CV test passed
Thanks,

Hi Kiruthikka,
In your above post difference between failure and successful descriptor configuration is just the order in which formats are defined. So you say that if the order is changed from MJPEG, MJPEG, YUY2 to MJPEG, YUY2, MJPEG CV test passes. Can you please attach both versions of descriptor files(having MJPEG and YUY2) - the one which fails and the one which passes?
Regards,
