Changes in "Camera Parameters" don't make effect #105

Closed alefelipeoliveira closed 5 years ago

alefelipeoliveira commented 6 years ago

Hello everyone,

I and trying to change some camera (using V4L) parameters as follows: brightness, gain, sharpness, contrast... But when I change the parameters value, nothing change in the display of camera 0. Do you know why these parameters don't change? Do I need enable something?

Tks a lot

The V4L support in ssl-vision is minimal and not really useful for a real game. It is good to get a first shot, but not more. The latencies via the V4L path are just too high. Furthermore, several features are not supported like the brightness and gain changes you mention. V4L is only a very high abstraction of features common to all cameras (i.e. primary a simple video stream). I recommend to close this with "won't fix", sorry!
