The launcher script from the Builder Wizard detects #cpus and sets an environment variable MLT_AVFORMAT_THREADS=n. You can also set threads=n as a property in a render profile. This thread count is not the overall thread count. It is the number of FFmpeg worker threads for video encoding (and decoding if using MLT_AVFORMAT_THREADS). Therefore, you might want to set this to #core -1 or -2. Also, it only works for some codecs; it works exceptionally well for x264. -- +-DRD-+ ------------------------------------------------------------------------------ Open Source Business Conference (OSBC), March 24-25, 2009, San Francisco, CA -OSBC tackles the biggest issue in open source: Open Sourcing the Enterprise -Strategies to boost innovation and cut costs with open source participation -Receive a $600 discount off the registration fee with the source code: SFAD http://p.sf.net/sfu/XcvMzF8H _______________________________________________ Kdenlive-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/kdenlive-devel
