Hi Fernando,<br><br>Apologies for the late response.<br><br>I (re)encoded the films in Avidemux on my Puredyne machine using the mjpeg codec. There is a Windows version of Avidemux too.<br><br>I switched to borrowed Windows and Mac machines for testing as my Puredyne lappy wont drive the patch. Too processing intensive. I had more problems on the Windows 7 machine but that may well have something to do with running 32b pd on a 64b machine, not sure, and didn't have enough time to test thoroughly.<br>
<br>There seems to be so many possible variables with OS's, graphics cards, etc. etc. that each use of video within pd has its own particular set of problems. As my films are quite static I reduced the frame rate and quality, which seemed to help. As someone just starting to work this way it does seem to have some tricky issues. I'm fairly determined to keep my work in pd so I expect to pick up more tips and tricks as the work progresses.<br>
<br>Best of luck with your patch and I hope the recoding may do the trick.<br><br>All good wishes,<br><br>Jb<br><br><br><br><div class="gmail_quote">On 2 October 2010 18:42, Fernando Krum <span dir="ltr"><<a href="mailto:ferkrum@gmail.com">ferkrum@gmail.com</a>></span> wrote:<br>

i´m trying to play 2 videos simultaneously on a Windows machine.<br>But whenever i try to make it fullscreen it will decrease framerate and apparently<br>
uses a lot o cpu processing... i think a have problems with encoders on my windows<br>machine.<br>which encoder are you using ??<br><br>thanx a lot,<br><br>Fernando.<br><font color="#888888"><br><br clear="all">Fernando Krum<br>

Try this patch and abstraction and use small soundfiles and movies to<br>
test.<br>
I don't know which video codec is better on Windows for your patch.<br>

</div>You needn't $0 in your patch but it is a good practice if you want to<br>
send variables in local.<br>
In your subpatch you use '$0-frame' to send the number of frame of your<br>
movies. The problem is all your receive $0-frame will receive the value<br>
of the 3 movies.<br>
So i remove these objects (heve a look inside the subpatch).<br>
