Hello, I have a Gnlcomposition with 2 gnlfilesources (videofiles), I need to render text in a customizable manner. For instance, at certain time file1 needs text over it and file2 doesn't and viceversa or even both could need the text rendered over them. I could put a text in the common queue, so it always appears and it isn't the needed behavior. I appreciate any clue, thanks Rossana The pipeline GnlComposition gnlfilesource1 --------------------gnlOperarion--------queue-----sink // I put the textoverlay between the queue and the sink gnlfilesource2 gnlOperation //for crossfade purposes alpha1 ----------videomixer--------ffmpegcolor alpha2
