In that case, is there a way to achieve lumakey alternatively? I am experimenting to extract the brightest portion (naturally the white background) from the picture ( http://picpaste.com/qJ4WNPHY.jpg) and replace that with a transparent layer, based on luminance value. I read here at https://ffmpeg.org/pipermail/ffmpeg-user/2011-July/001793.html that geq filter can be of help to the yuv formats, but could not figure out how? Any inputs appreciated! > >>> Cheers, >>> /z >>> >> _______________________________________________ >> ffmpeg-user mailing list >> [email protected] >> http://ffmpeg.org/mailman/listinfo/ffmpeg-user >> > _______________________________________________ > ffmpeg-user mailing list > [email protected] > http://ffmpeg.org/mailman/listinfo/ffmpeg-user > _______________________________________________ ffmpeg-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/ffmpeg-user
