"UVC webcam to hdmi" have many detail technical problem to be solve
1. UVC Webcam video stream
UVC webcam have YUV and MJPG stream
YUV means no compression . MJPG menas compression stream.
YUV video frame rate will be slower than MJPG video frame rate.
Each YUV and each MJPG also have difference resolution.
if you catch 640X 480 resolution, the resolution is bad.
The best uvc stream that be caught is MJPG 1280X720.
The reason is as below

if you caugh 1920x1080 uvc, the frame rate will be reduce.
2. HDMI output is 1920X1080P
After getting the uvc stream, it will be convert to 1920x1080p hdmi output.
