[abcfy2]

Will xviewer plan to support webp image?

[artik]

Any news about support of webp format?

Please! add the support for Webp files {as gThumb that apparently uses 'libwebp' librarie}

[navin09]

+1 Pretty please? With sugar on top?

[raniesantos]

The use of webp is slowly spreading, it would be good to have this feature now.

[thunderamur]

I need this feature. Vote for this feature request!

[Arinelle]

Yes please, this is becoming very handicapping!

[cptX]

4 years since the first request? Are you planning to implement this soon? Webp format is used more and more nowadays!

[craigs100]

Please get webp sorted. There are web developers needing this. webp is now supported by the majority of browsers.

I just built from source and installed libwebp6 and it seems to be working.. 🤔

[cptX]

Have you build xviewer from source you mean? When is this going to be streamed to the repositories?

[iSWORD]

Yeah I built xviewer from source then installed libwebp from repos.

It seems the support for webp is really basic though. Navigating with left and right keys doesn't show any other images than the one you opened initially and some webp images still fail to load.

I then updated to 20.1 and realized it is in the repos, but then I uninstalled xviewer and started using gthumb instead :(

[picarica]

is it supported? i am using newest 20.1 focal and yet i cant open .webp images even with libwebp6 installed

[craigs100]

I've given up and just use gThumb for svg's

This is upstream from us, it's not something we can fix in xviewer itself. The picture isn't loaded by xviewer directly but by GdkPixbufLoader.

See:

• https://bugzilla.gnome.org/show_bug.cgi?id=700751
• /usr/bin/gdk-pixbuf-query-loaders is no more available in debian and ubuntu aruiz/webp-pixbuf-loader#9
• https://bugs.launchpad.net/ubuntu/+source/gdk-pixbuf/+bug/1864215
• https://gitlab.gnome.org/GNOME/eog/-/issues/45

Once this is fixed upstream xviewer will be able to load webp pictures without any code changes. What we'll need to do though, when that happens, and depending on how it's done, is make xviewer accept the mimetype (that's really easy though) so that you can double-click the file to open xviewer.

In the meantime you can associate pix to webp images, it supports it well.

@iSWORD if you can shed more light on how you got this to work... I've got libweb 0.6.1-2 here and xviewer still fails to load that format, recompiling it doesn't help.

[iSWORD]

@clefebvre I have no idea how I got it to work. I've been trying to reproduce it in a VM for two hours to no avail.

I still have my installation that got it to work, I'm not sure what to dump to help. My package list is HUGE and I have no clue what to leave out.

[cptX]

Mine is version 2.4.3 and doesn't open it

Which linux version do you have?

[Hordeking]

I'm on Mint 20.1, xviewer 2.8.3. libwebp6 is installed, I'm getting nothing. Is this an issue with the package maintainer not building against the libwebp library possibly? I don't know who that is or I would ping them to loop them in.

pqiv https://github.com/phillipberndt/pqiv seems to use gtk3 and gdk-pixbuf and is able to display webp images (with libwep installed). May they have found a working solution?

[tudo75]

I tried this and seems to work
https://github.com/aruiz/webp-pixbuf-loader

[joka42]

@tudo75 what do you have to do in order to get it to work? (after building and installing as said in the readme?)

[tudo75]

@joka42 I followed the build instruction for ubuntu (I'm on linux mint 20.2 xfce) and installed. you can check after install if file exist
/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-webp.so
and
there are these lines

"/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders/libpixbufloader-webp.so"
"webp" 5 "gdk-pixbuf" "The WebP image format" "LGPL"
"image/webp" "audio/x-riff" ""
"webp" ""
"RIFFsizeWEBP" "    xxxx    " 100

in
/usr/lib/x86_64-linux-gnu/gdk-pixbuf-2.0/2.10.0/loaders.cache

PS: I also compiled it under MSYS2 on windows without any problem

[joka42]

@tudo75 I am in Manjaro (Cinnamon) and I could find the libs in /usr/lib/gdk-pixbuf-2.0/... also the loaders.cache files contained the lines you mentioned, but still get the following error in xviewer:

Edit:
(also after a reboot)
Edit 2:
Ok, I got it, it only works with non-animated .webp images. That does only solve 5% of my problem. Thanks anyway! :-)

[tudo75]

@joka42
there is a pull request for the webp-pixbuf-loader that add animated webp support
you can find it here
https://github.com/alanhaw/webp-pixbuf-loader
And here, there is the discussion
aruiz/webp-pixbuf-loader#30
I installed and tested it and worked with some animated images found after a rapid search

[haggen88]

@clefebvre @JosephMcc @mtwebster
.
I followed the steps in this guide and webp-pixbuf-loader worked for me (Mint 20.2):

[danielp96]

The guide haggen88 mentioned worked for me on Mint 20.3 and xviewer 3.2.4.
Webp files now show thumbnails on nemo and can be viewed on xviewer.

[artik]

It worked for me also, thanks @haggen88
Having it packaged in mint would be a good thing as this format starts to be quite spreaded

[joka42]

Thanks @tudo75 I built the repo from source and it works well with animated webp images in mint 20.3.

[joka42]

The open MR has been merged to also support animated webp images. Here is the latest release: https://github.com/aruiz/webp-pixbuf-loader/releases/tag/0.0.4

how to

install dependencies:
sudo apt install libwebp-dev libgdk-pixbuf2.0-dev libgtk-3-dev meson build-essential

build from source and install as described in the readme.md.

[haggen88]

There are good news. It is part of the roadmap:
