I am trying to make an animation of the double pendulum using the
attached script (v1.1.x branch). It creates all the files _tmp*.png,
and creates the mpg but it has zero file size. If I manually make the
movie with the resultant PNGs, it works fine
mencoder mf://_tmp*.png -mf type=png:fps=15 -ovc lavc -lavcopts
vcodec=mpeg4 -oac copy -o test2.mpg
I need to add some debugging output to animation.py (we should add
lots of verbose.report command in there to see what is going on, I'm
going to try and get a pull request together) but I thought I'd fire
this off to anyone else has the same problems or if I'm doing it
wrong. I do have ffmpeg and mencoder installed on my 64bit ubuntu
11.04 box.
Thanks,
JDH
