<div class="gmail_quote"><div>Hi Jean,</div><div><br></div><div>there was actually a discussion few days ago here, about the [pd~] and optimization topic.</div><div><br></div><div>However, for audiovisual processes, apparently it's still more reliable to use two different instances of Pd.</div>
<div>One proceses the sound and the other the video.</div><div>The video Pd instance might gain some more cpu resources when launched with the flag -noaudio.</div><div>Then you want to exchange data between patches on a local network on your machine using [netsend] and [netreceive].</div>
<div><br></div><div>AFAIK, the main feature of [pd~] is to keep synced processes happening in different threads.</div><div>Thus, when one of the processes slows down, the others slow down too.</div><div>Which, can be good for audio projects, but audio and video patches won't work really well due to this feature.</div>
<div> </div><div>cheers,</div><div>Marco</div><div><br></div><div><br></div><div> </div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Is there a strategy to optimize GEM video processing and real time<br>
audio on a single Mac using pd~ :<br>
<br>
Audio in subprocess or in main process ?<br>
Any startup flags ? chmod +s stuff ? shm settings ?<br>
Run two instances of PD with messages between them ?<br>
Subprocess fifo size ?<br>
