Animations in ipython (jupyter) notebook - ValueError: I/O operation on closed file

Question

I have a jupyter notebook that produces an animation. It was working on my old laptop (xubuntu gnu/linux). Now on my new laptop (trisquel gnu/linux) it\'s not working. This

Answer 1

I ran into the same issue (on a mac os 10.12.2), and fixed it by reinstalling ffmpeg and enabling the x264 codec , which the to_html5_video() function needs to convert the animation to html5.

To install x264:

cd /my/path/where/i/keep/compiled/stuff
git clone git://git.videolan.org/x264.git
cd x264
./configure --enable-static --enable-shared
make
make install
ldconfig # note: use for linux, not necessary for mac

source

To install ffmpeg with the x264 codec enabled:

cd /my/path/where/i/keep/compiled/stuff
git clone http://source.ffmpeg.org/git/ffmpeg.git
cd ffmpeg
./configure --enable-gpl --enable-libx264
make
make install
ldconfig # note: use for linux, not necessary for mac
