Hi, I'm trying to use a Blackmagic Design DeckLink Mini Monitor. MLT provides me output. Idealy I would like to have a way to continously loop the inputscript. I read that that a "high" repeat would emulate a loop best.
/opt/mlt/bin/melt -profile dv_pal_wide eof=loop /home/tv/kabelkrant.mlt -repeat 1000000 -consumer decklink The above functions. I am using a moving background and a png to overlay ontop of it. <?xml version="1.0" ?> <mlt> <!-- clip --> <producer id="clip1"> <property name="resource">/home/tv/test.png</property> </producer> <producer id="clip2"> <property name="resource">/home/tv/logo.png</property> </producer> <!-- cg --> <producer id="cg"> <property name="resource">/home/tv/FGTV_ACHTERGROND_10.mp4</property> </producer> <!-- cg loop --> <playlist id="clips"> <entry producer="clip1" in="0.0" out="400.0" /> <entry producer="clip2" in="400.0" out="800.0" /> </playlist> <playlist id="cg_loop" eof="loop"> <entry producer="cg" eof="loop"/> </playlist> <tractor eof="loop"> <multitrack> <track producer="clips" in="0.0" out="800.0"/> <track producer="cg_loop" in="0.0" out="800.0"/> </multitrack> <!-- clip and cg blending --> <transition in="0.0" out="800.0"> <property name="mlt_service">composite</property> <property name="a_track">1</property> <property name="b_track">0</property> <property name="fill">1</property> </transition> </tractor> </mlt> Now the output looks bad, and I mean: linear scaling bad. I wonder, how does MLT currently make wide-screen pal, or scaling at all? At what step does it downscale to anamorphically 720x576? I see that the larger the input resolution is, the worse edges become at the output. Any pro tips? Is it for example possible to have the tractor at HD resolution and have the consumer downscale it? And a more pragmatic question: is it possible to use VDPAU in combination with Decklink output? Or is the idea stupid, and is it much better to use a DVI->HDMI->SDI conversion? -- Stefan ------------------------------------------------------------------------------ Dive into the World of Parallel Programming The Go Parallel Website, sponsored by Intel and developed in partnership with Slashdot Media, is your hub for all things parallel software development, from weekly thought leadership blogs to news, videos, case studies, tutorials and more.
