Support OS 10.10 / Yosemite

[mimecuvalo]

Currently busted in Yosemite unfortunately. :-/

[dchest]

Looks like recompiling with newer Xcode solves the crash. Could you please try the new release? https://github.com/dchest/webp-quicklook/releases/tag/v2.2

(You may need to restart Mac after replacing qlgenerator).

[mimecuvalo]

Yeah, before contacting you I had tried myself recompiling with Xcode but to no avail.
Trying your latest release doesn't seem to fix it as far as I can tell :-/ I had tried restarting and running qlmanage -r as well. Not sure what's up.

[dchest]

Strange, it works for me. Could you please post the output this command (and whether it shows the preview):

qlmanage -g "/Users/dchest/Library/QuickLook/WebP.qlgenerator" -c "com.google.webp" -p ~/Desktop/picture.webp

(Replace paths with yours, of course)

also this:

qlmanage -m | grep webp

[mimecuvalo]

Here's the output:

[dchest]

Thanks. I have the same output and then it shows the preview. What you get instead? If it doesn't show the preview, could you send me the file you're trying to preview if it's possible? dmitry@codingrobots.com

[mimecuvalo]

It does show the preview correctly. It's only in Finder where the preview doesn't show up unfortunately. Finder looks like this:

[dchest]

@mimecuvalo hmm, maybe some other QuickLook generator kicks in instead of this one (although qlmanage shows the right one...)? Or maybe there's something with this particular .webp file? Could you try if this one works: https://www.gstatic.com/webp/gallery3/1_webp_ll.webp

[mimecuvalo]

Yeah, I tried with the test image and other images and on a different machine. Didn't work as well :-/

[dchest]

I'm out of ideas :( Can't reproduce this, unfortunately.

[mimecuvalo]

No worries, thanks for checking it out in the first place - I'll dig in some more into the code when I get some time later ;)

[mimecuvalo]

This seems to be working now - I moved it to /Library instead of my home directory ~/Library - that was the problem.

[dchest]

Thanks! Strange that it didn't work in ~/Library.

[vitorgalvao]

@dchest It’d likely be valuable to keep this open, since the underlying issue hasn’t been resolved.

On homebrew-cask we had an issue open recently pertaining to this, which is how I found this issue.

After some tests I found this issue, whatever the cause, also affects @emin’s plugin, so maybe you’d be interested in working together on it. So far, every other quicklook plugin I’ve tried seems to be working normally.

[dchest]

I'm reopening the issue. But I still can't reproduce the bug — it works on my machine (I have WebP.qlgenerator in ~/Library/QuickLook, and I verified that it is really it that shows previews). Can I ask someone who's having this issue to create a new OS X account on their machine and try putting it again in ~/Library/QuickLook for that account (make sure to delete the one in /Library/QuickLook first)?

[orzFly]

Didn't work after installing from brew-cask as it created a symlink to WebP.qlgenerator in ~/Library/QuickLook. However, I replaced the symlink with the actual bundle and then it got to be working now!

I hope this helps!

In my case the quicklook generator in Pixelmator was taking preference (and wasn't working). I disabled it by editing /Applications/Pixelmator.app/Contents/Library/QuickLook/PixelmatorLook.qlgenerator/Contents/Info.plist and removing the webp document type.

[FirePanther]

For me it was pixelmators fault, thank you @felixbuenemann. It even didn't work by moving to /Library. (OSX10.11)

[zmwangx]

Just so you guys know, I was having the same issue on El Cap due to Pixelmator, and I've emailed bugs@pixelmator.com asking them to unbind public.webp from PixelmatorLook.qlgenerator/Contents/Info.plist. I also started a support forum thread: http://support.pixelmator.com/viewtopic.php?t=12602.

[dchest]

Thanks everyone, it looks like it's a Pixelmator bug, so I'm closing this issue. Feel free to comment here if they resolve it.

[kentliau]

As of today, Pixelmator (v3.5 Canyon) still hasn't deal with webp problem yet. For anyone encounter the similar problem, a quick workaround is remove public.webp extension binding yourself in /Applications/Pixelmator.app/Contents/Library/QuickLook/PixelmatorLook.qlgenerator/Contents/info.plist

[zmwangx]

@kentliau You might want to email bugs@pixelmator.com. The more user complaints, the more likely they're going to take this issue seriously.

[mattstein]

@felixbuenemann's fix just worked for me as well, thank you. I sent an email to bugs@pixelmator.com as @zmwangx suggested, so hopefully that ticket will get some attention.

[mattstein]

FWIW I got a fairly quick response from Pixelmator:

Thanks for getting in touch and giving us a heads up about this – this is still on our radar. :)
