[sage-devel] pathname escaping in animate().gif

[William Orrick]

I have encountered the problem that when I try running

bdFrames.gif(delay=5,savefile='myFilename',use_ffmpeg=True)

the following error message is produced:

CalledProcessError: Command 'cd 
"/var/folders/v8/ksjcxlh9775658j_hrwqvlj80000gq/T/tmpzm1odw2y/dir_ivudixzd/"; 
ffmpeg -nostdin -y -f image2 -r 20 -i 
/var/folders/v8/ksjcxlh9775658j_hrwqvlj80000gq/T/tmpzm1odw2y/dir_ivudixzd/%08d.png
 
-pix_fmt rgb24 -loop 0 /Users/williamorrick2/Jupyter 
Notebooks/myFileName.gif' returned non-zero exit status 1.
The issue seems to be that the pathname to my working directory contains a 
space character, which is not being escaped. When I run this myself from 
the command line, with quotation marks around the pathname, it works fine.
I'm not a developer, and don't know if this is a known issue.
