Successful test with this "generic" camera with the settings below. Above 800x480 the streaming got way too laggy.

• 176x144 30FPS MJPEG
• 320x240 30FPS MJPEG
• 640x360 30FPS MJPEG
• 640x480 30FPS MJPEG
• 800x480 30FPS MJPEG
• 1280x720 30FPS MJPEG
• 1920x1080 30FPS MJPEG

For the scenarios that weren't available on menuconfig, I used the "Force setting" block:

#if 1
    // Force setting
    width = 1920;
    height = 1080;
    fps = 30;
    format = UVC_FRAME_FORMAT_MJPEG;
#endif

Thank you for the report.
Where is DEMO_UVC_XFER_BUFFER_SIZE define used?
I did grep but couldn't find it.

$ cd esp-idf-video-streaming
$ grep -rn "DEMO_UVC_XFER_BUFFER_SIZE" *

Thank you for the report. Where is DEMO_UVC_XFER_BUFFER_SIZE define used? I did grep but couldn't find it.

Sorry, I had tested it with a different driver and mixed up the codes. The report is correct now.

The setting I was reffering to is from Espressif's USB Stream Example.
