I added to onAfterDecodeFrame:

sourceVideo.grabFrame(new GrabResult(), sourceWidth, sourceHeight);

but the picture with a logo

how I can get the pic whithout overlays?

P.S. My final task to change all frame with Transcoder, like - get snipeshot, modify pic, insert with Overlay

Thanks,

Hi,

Have you looked into adding it to onBeforeScaleFrame? Accessing the frame prior to being transcoded was discussed similarly in another post.
