For example, after doing some basic editing on a HDV project with two stereo audio tracks and one video track, I wanted to move one audio track down in the timeline. When I did this, I triggered a race condition that hung a CPU at 100% for 30 minutes. Bummer.
Hannes gave me some instruction last year on how to track these issues down using kdbg: http://crazedmuleproductions.blogspot.com/search/label/kdbg I will try to capture some debug information the next time it happens. scott _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
