Re: Video generation on linux systems: Note and rests change color

That solved the problem for me. I changed the usleep 250 to sleep 0.000250 in mkvideo. Now the short video_mwe.ly goes pretty fast. My own first project takes a little longer, for example while "bursting pdf...", but with 200 pages i think that's o.k. For the cpu load shows 100% instead of

Re: Video generation on linux systems: Note and rests change color

Yes, but it's a factor of a million, not a thousand, so sleep 0.00025 would be appropriate as a replacement for usleep 250. Any short sleep is ok at that place of the script  ... Knut ___ lilypond-user mailing list lilypond-user@gnu.org
