TranscoderVideoDecoderNotifyBase + ITranscoderFrameGrabResult


I use graphic overlays to add logo in transcode strem:

Add graphic overlays

and I need to get thumbnail images

get thumbnail images

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



Maybe someone can suggest how to create new thread whith grab images?


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