I've got PDP and PiDiP working well now. I'm using a webcam stream on one place on a pdp_canvas, recording it, and playing it via pdp_qt at other places on the canvas. This works well, but if I try to run both the stream and recorded .mov I get a steady stream of pdp_drops, memory usage goes through the roof, and brings everything to a grinding halt or makes a segmentation fault. I read this in the archives:

that's perfectly normal, this behaviour you get : that's because PiDiP objects do not support grey scale images, you have to pass yuv12 packets to them and, then, eventually, turn the result into grey images with "pdp_grey".
no,this is obsolete now, all packets are converted internally.
Is this the same problem? If so, how can I convert the stream to yuv12 before it gets to pdp_rec~? Should I maybe be using pdp_yqt instead of pdp_qt?
this, yes, it's lighter.
I have pdp in its own thread, a [block~ 131072 8] which doesn't seem to help, and memory usage set to 100 megs max.
it's not so much, especially for the canvas.
Problem is, instead of managing the memory as I'd hoped, it just exits when it goes over that limit. I am trying to loop the video with pdp_qt
there is a 'loop' message to pdp_qt or pdp_yqt for that purpose.
