Error with write_videofile

[wgaylord]

Yes I realize there are two other issues about this but none of the issues seem to have answers.

This was executed in a directory containing 694 .jpg files. Could this be because my system is using a 64-bit install of python and imageio install a 32-bit version of ffmpeg? (When I ran the function to install ffmpeg it had 32 in its name.)

More information.
Windows 10 64-bit
Python 2.7.13 (v2.7.13:a06454b1afa1, Dec 17 2016, 20:53:40)

@wgaylord could you share the error traceback with proper formating (i.e, as code, so it preserve right indentation). It's very hard to read in this way, and make very difficult to help you

[tburrows13]

@mgaitan I’ve edited the original post to properly format the code. Thank you for trying to help!

[mgaitan]

are you sure there is only images on that directory? could you debug it?

[wgaylord]

What else do you need me to debug? I have no other information and yes I am sure they are all images. This was not a problem when I used 32-bit python last year. But now it’s not working now that I am on a new computer with 64-bit python.

[mgaitan]

For instance, which are the values uri and format on the problematic line

 reader = read(uri, format, 'i', **kwargs)

on ipython, you can enter in a postmortem debugger after running %pdb.

anyway, this seems to be a duplicated of #219 , and what I guessed is that it could be a hidden file like a ".DS_store"`in the same directory, and somebody point that here #219 (comment)

@wgaylord Did you manage to solve the issue? Was it indeed a duplicate of the other issue mentioned (above)?

[keikoro]

(Looking to label/close this if it's a dupe.)

[wgaylord]

Well as I can’t give you more information. I say close this. As I have used it on other images. Still can’t get it to work on those images even when I move them to another folder.
