Could you please help setup a picture in picture PIP of RPI camera, I would like to show the camera in full screen and then show a zoomed area of the camera on top of the full screen video. Thanks

example-texture-mode somewhat does this - you will just have to scale/mask the second texture to simulate the zooming

thanks, i have this issue, when resizing the screen i.e. omxCameraSettings.width = 1280; //default 1280 omxCameraSettings.height = 720; to omxCameraSettings.width = 720; //default 1280 omxCameraSettings.height = 480; //default 720, the screen goes white? please if you may help.

typically it means you don't have enough memory assigned to the GPU. You should have at least 128MB but 256 is better.

thx, i narrowed it down to omxCameraSettings.enableTexture = false; . if this is false it work, also my gnu em is gpu_mem=256...
