AttributeError: 'NoneType' object has no attribute 'group' when using remote gif URL

I had the same issue detailed in issue 7 and on deleting the directory specified got the following regex exception instead:

$ gif-for-cli 10988977

Traceback (most recent call last):

AttributeError: 'NoneType' object has no attribute 'group'

python3.6 on debian 8.0

Should point out, works fine on local gifs.

That means something went wrong with ffmpeg, and it's not giving the output we expect.

What version of ffmpeg are you using?

Yes you're right, it was only affecting HTTPS connections. Adding --enable-openssl when configuring FFMPEG fixed.

I'll reopen this, gif-for-cli should handle this error better and try to warn the user ffmpeg needs to be reconfigured.

Thanks for your help!

The same happens with local paths and --export key (which is broken anyway, but still).
