I haven't done any capture work with Cinelerra myself, but I can tell you that it is an NLE, that is a non-linear editor, which means it's not intended for real-time operations. Will you be displaying the rendered output on some live display during recording, or do you just need reliable real-time capture? If the latter, why not just capture the raw DV streams with dvgrab or similar, then edit them in Cinelerra later to create the split-screen effect? If the former, you might be able to set up a pipe using dvgrab and a series of mjpegtools to accomplish what you need. Something like dvgrab <parameters> | lavplay | yuvscaler <upper portion of the screen> > fifoTop.yuv and a similar command for the bottom half in a second terminal (on a second processor core, preferably.) I don't know if yuvplay supports joining, but if so, in a third terminal you could try yuvplay fifoTop.yuv fifoBottom.yuv | mpeg2enc <parameters> -o final.mpg Sean <<--------------------------------------------------------------------------------->> This E-Mail message has been scanned for viruses and cleared by >>SmartMail<< from Smarter Technology, Inc. <<--------------------------------------------------------------------------------->> _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
