    Default TranscoderVideoDecoderNotifyBase + ITranscoderFrameGrabResult

    Hello,
    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
    Thanks,

    Hi,

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