[saintlain]

Bug description

no webm resources load when using the derpibooru profile

Steps to reproduce

1. use derpibooru profile
2. attempt any search that yields webm results (e.g. 'webm')
3. any webm thumbnails will stay stuck loading, and the user cannot click them to open the image viewer to view full size

Expected behavior

webm resources should behave uniformly with gif/png/jpg/svg resources

Workaround

1. right click 'grabber' in applications and click 'show package content'
2. navigate to ./MacOS/sites/Philomena
3. replace model.js with the following:

        }
    }

};

            img.file_url = uris["full"];
        }
    }
    if (!img.preview_url && img.file_url && img.file_url.length >= 5) {
        img.preview_url = img.file_url

this modifies 2 lines of code to load .gif thumbnail files instead of .webm, and .mp4 for full size files instead of .webm

[Bionus]

Indeed, the thumbnails not working is a real issue and your fix works fine, thanks!

However, not so sure about enforcing MP4. It seems that the "native" format on Derpibooru is WEBM, and MP4 are converted from it:

As such, downloading the MP4 would mean not downloading the original file, which would be against the point IMO.

I added a PREFER_MP4 constant in the model file for now which you can set to true instead.

definitely agree! to be perfectly clear, i did not intend to suggest doing this as a permanent solution, just to offer a quick and dirty workaround for anyone who may be affected by this bug for the time being. ty 4 ur work
