Hi Why not use Watermark Filter. E.g. In case you want to overlay or repeat a video. I find Watermark filter quite useful.
E.g. melt A_David_Beckham.mp4 -filter watermark:/home/abhijit/MLT-test/L-Bands/MOV/ArrowLogo.mov in=50 out=700 Command above will overlay Arrow Logo for duration longer than Arrow MOV file. In case you have background/foreground requirements use -track attribute. Well explained in samples http://www.mltframework.org/bin/view/MLT/MltMelt Regards, Abhijit On 22 October 2015 at 08:32, jeffrey k eliasen <j...@jke.net> wrote: > So if I were to make the background playlist something like this: > > <playlist id="playlist_background" eof="loop"> > <entry producer="producer_background"/> > <entry producer="producer_background"/> > <entry producer="producer_background"/> > </playlist> > > … is there any performance problem with doing it that way?
