Traversing directories?

[anthonybruno]

I'm attempting to generate various webp graphics that are within multiple folders as such:

images
- foo
-- image.jpg
- bar
-- another-image.jpg

I've attempted various gulp wildcards for the src such as:

gulp.task('webp', function () {
    return gulp.src('app/images/**/*')
        .pipe(webp())
        .pipe(gulp.dest('dist/images'));
});

and the following error I receive from terminal.app is:

[16:38:40] Starting 'webp'...

events.js:72
        throw er; // Unhandled 'error' event
              ^
Error: Command failed: Error! Could not process file /var/folders/00/1snt0000h01000cxqpysvccm0076q8/T/be10a616-a515-4f9b-941a-fb9c2df9a769

Is it possible to maintain my folder structure?

Are you using the latest version of this plugin? Kinda looks like you're trying to pass it a non-image. Try using gulp-debug to see which file it fails on.

Looks like I had a unknown mp4 file within my directory which was causing the error.

Thanks for the speedy response! Awesome!
