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

[Christian Alpen]

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 before with usleep 250. So I 
know it's working and not stuck.

I have some further questions (if they still fit in here?):

1. Is the ./kptestpiano.sf2 desperately needed? As I couldn't get this 
prerepuisite solved, I followed Karlin's tip
     and replaced it with 'usr/share/sounds/sf2/FluidR3_GM.sf2'

2. Can the metronom be skipped by some command in the .ly-file? Or do I 
Have to edit the mkvideo for that?

3. Am I bound to 16:9 format, or is it possible for example to view an 
entire A4 page?

4. What about repeats? Right now I one part with repeats, that is only 
rendered once. Of course there
    is a workound with editing the video. But would it be possible to 
get this done while generating the video?

Thanks a lot for all your help!
