hi,I use fx3 transfer video to PC with UVC.
my camera is 1920*720@30fps YUV2.
I updata cyfxuvcdscr.c file of AN75799.
0x10, /* X dimension of the picture aspect ratio; Non-interlaced */
0x06, /* Y dimension of the pictuer aspect ratio: Non-interlaced */
/* Class specific Uncompressed VS frame descriptor - 1 (720p) */
0x1E, /* Descriptor size */
0x24, /* Descriptor type*/
0x05, /* Subtype: uncompressed frame I/F */
UVC_SS_720P_FRAME_INDEX, /* Frame Descriptor Index */
0x02, /* Still image capture method 2 supported */
0x80, 0x07, /* Width in pixel: 1280*/
0xD0, 0x02, /* Height in pixel: 720 */
0x00,0x00,0x8D,0x27, /* Min bit rate bits/s - 1280*720*16*30 = 0x1a5e0000*/
0x00,0x00,0x8D,0x27, /* Max bit rate bits/s */
0x00,0x76,0x2F,0x00, /* Maximum video or still frame size in bytes(Deprecated)*/
0x15, 0x16, 0x05, 0x00, /* 30fps */
0x01,
0x15,0x16,0x05,0x00,
0x80, 0x07, /* Width in pixel - 1280 */
0xD0, 0x02, /* Height in pixel - 720 */
it works, PC can show video.
but 30fps is unstable, first is 30fps for seconds, and then down to 6fps ,and up.but 81001KB is stable.
Please help,thanks!
