Hi everybody.
I have been trying to save some animations I made and I
encountered the problem mentioned here
<http://sourceforge.net/mailarchive/forum.php?thread_name=CAKH0P%2BVLXthNCAZ1K2pKHYqqPiFHP5iXSFwJvEerVmvtmgGv0g%40mail.gmail.com&forum_name=matplotlib-devel>.
I am using current master.
To be precise, when I use
anim.save("file.mp4", fps=10, extra_args=['-vcodec', 'libx264'])
I get "RuntimeError: Error writing to file" from the agg backend.
If I don't use the extra_args, it works, but I get very, very bad
quality that can not be redeemed using bitrate.
I have ffmpeg and libx264 installed. I also tried the mencoder by
passing
MencoderWriter() to save, but that resulted in a video where all
frames are identical.
Any help on this would be appreciated. Is there an easy way to
just dump
the frames? I can do the mencoder bit myself.
Thanks,
Andy
Exactly which version of mpl are you using, and what is your
platform? This will help us diagnose what is going on.
Thanks for the quick answer.
I am not on the box but I used master from yesterday, so
89482b21c8582d49a2ddc2865e472eb404fd07e2
<https://github.com/matplotlib/matplotlib/commit/89482b21c8582d49a2ddc2865e472eb404fd07e2>,
I guess.
The platform is Ubuntu Precise (with loads of random Python
packages, but that seems somewhat unrelated).
Cheers,
Andy
