Video frame looks like mozaik. What wrong with it and how can be fixed?
Is any other library that can show video with less processor resources
This seems like there's something wrong with the initial offset of the video data and/or the stride. Are you sure all parameters used in your code are correct? Never experienced something like that while using EmguCV (and just showing camera input). The blue borders on the left/right are some background/outside stuff I assume? Or is the whole picture your camera image?
