Hi All,

This is my first post on this forum. If I am wrong in any case please forgive me. Please advice me in the following topic.

I am new to QT and SDL. I have an API written in C, which gives me raw video frames in YUV 4:2:0 format from 4 camera's, which I want to render on the screen simultaneously, by splitting whole screen in to 4. May be I will increase the number of sources from 4 to 8 or 16 once if I get the solution to this. How can I do this ? Looking for your valuable guidance.

Thanks,
Venkata Subba Rao

You might start by searching the forum. There has been a similar thread some time ago. There is also a solution in our wiki, but if you want multiple sources, I'd go for an OpenGL solution (maybe even using fragment shaders to convert from YUV to RGB).
