Hi!
From what I read webp supports animation. Given a set of X jpg images
how can I convert them to an animated webp?
-R.

The immediate answer would be to embed a webm video, which webp is
based of. However there may be some interest in a light-weight no-
audio animated variant of webp to replace animated gif. There are huge
compression benefits in doing this, however convincing enough people
to make the switch could be hard.

Hi,
Yes, WebP has a support for animation. You can create animated WebP images using the WebPMux library/binary as follows:
(Make sure you have the 'cwebp' and 'webpmux' binaries).
(1) Convert all the JPEG images to WebP using the 'cwebp' binary. e.g.
for file in *.jpg; do cwebp ${file} -o ${file%.jpg}.webp; done
(2) Now, create an animated WebP image, from multiple WebP images created in step 1, using 'webpmux' binary.
For example, suppose you want to create an animation from 1.webp, 2.webp, 3.webp & 4.webp where
- Duration (in milliseconds) between frames is 100, 200, 300 & 400 respectively.
- Animation loops 1000 times
- Each frame has image offset (0,0) [that is, the top left pixel of each frame is located at (0,0)].
You can use the following command to achieve this:
webpmux -frame 1.webp +0+0+100 -frame 2.webp +0+0+200 -frame 3.webp +0+0+300 -frame 4.webp +0+0+400 -loop 1000 -o animation.webp
Hope this helps.

It does help, and if I get it working hopefully I'll make something
cool.
Question: where can I get WebPMux? I see premade packages only for
cwebp dwebp. Do I need to get the current trunk and compile it?

Yes, you can compile it from source. Download the latest source using: git clone http://git.chromium.org/webm/libwebp.git
Have a look at the README for installation instructions.
P.S. You can also have look at README.mux for more info on 'webpmux' binary and API.

Got it. I have it working, and I built a webp animation. Now, how can
I see it? I tried all builds of chrome (canary too) and it doesn't
seem to animate, it just shows a static image.

Hi Radu,
The library for demuxing animated files (libwebpmux) still need some polishing.
I have this patch sitting around https://gerrit.chromium.org/gerrit/21200
It makes examples/vwebp support animation.
But libwebpmux still has few problems handling transparently the animated (VP8X-based)
and non-animated "raw" bitstreams. I'll finish patch #21200 when libwebpmux
gets better at that.

actually, i submitted https://gerrit.chromium.org/gerrit/#change,22219 instead, that works as is
and doesn't require a libwebpmux update (yet!).
You can compile from HEAD using (dixit the patch description):
how to build and use manually (integration in makefile.unix coming soon)
Unix:
cd libwebp
make -f makefile.unix
cd examples
cc -o vwebp vwebp.c -framework GLUT -framework OpenGL -I../src/ ../src/libwebp.a ../src/mux/libwebpmux.a
Mac + xcode:
cd libwebp
make -f makefile.unix

Hi there,
Is there a tip on how to build this on Mac OS X?
When launching:
ld: library not found for -lglut
Should I port glut?
Thanks,

Hi
I built the animation using the last version from http://git.chromium.org/webm/libwebp.git
which includes the patch already (right?).
But in Chrome (Canary) it does not animate.

Hi David,
Yup, looks like mac/linux were invertered. Correct way to build is:
Mac + xcode:
cd libwebp
make -f makefile.unix
cd examples
cc -o vwebp vwebp.c -framework GLUT -framework OpenGL -I../src/ ../src/libwebp.a ../src/mux/libwebpmux.a
Unix:
cd libwebp
make -f makefile.unix
cd examples
cc -o vwebp vwebp.c -lglut -lGL -lpthread -lm -I../src/ ../src/libwebp.a ../src/mux/libwebpmux.a

Hi
I built the animation using the last version from http://git.chromium.org/webm/libwebp.git
which includes the patch already (right?).
But in Chrome (Canary) it does not animate.
Hi David,
Currently, Chrome uses an old version of libwebp, which doesn't contain advanced features like animation.
Plan is to release the next version of libwebp (v0.1.4) soon, which would support animation, tiling, XMP metadata, color profiles and alpha. After that release, Chrome would be able use the latest library to support animation.
In the meantime, you can preview all webp files (including animated images) using the binary "examples/vwebp". This binary can generated by the commands mentioned in the previous mail.
Try it out, and let me know what you think.

Thanks, I didn't know about WebPMux. Does this only compress inter-

individually?

WebPMux operates on compressed webp files, it packs them into an animation file. So the answer to your question is that they're stand-alone images. If the frame count or size was very high you could always move to <video>.

great!
'vwebp' is only a viewer for animated WebP files.
To create animations, you can use webpmux to assemble already-compiled WebP files.
For instance, if you already compressed 'frame1.webp', 'frame2.webp', 'frame3.webp', you can use:
webpmux -frame frame1.webp +40 \
-frame frame2.webp +40 \
-frame frame3.webp +40 \
-loop 10 -o anim.webp
And then view it with 'vwebp anim.webp'.
Here, "+40" is the duration in ms. 40ms corresponds to 25 frames/sec.
You can also directly convert a GIF to WebP using 'gif2webp anim.gif -o anim.webp'
but it's better to start from the original frames if possible, instead of the color-quantized GIF.

Hi,
It's not part of the source tree in the repository (but not yet in any of the official archive till 0.2.1. Hopefully in the next one!).
It's built by default, so you should have it available as 'examples/webpmux' if you use the HEAD tree.

You can download the binaries here:

You can use the 'gif2webp' tool from there to convert a GIF to WebP, and then use 'vwebp' tool to view it.

Oh I see. To mux multiple WebP images into an animated WebP image, you can use the 'webpmux' tool. This is also part of v0.3.0 release binaries (check here as noted earlier: https://code.google.com/p/webp/downloads/list).

And yes, this supports each frame of the animation to be of a different size, as well as each frame having different offsets.
You can run "webpmux -h" for help on using the tool.

Hi,
As noted by "webpmux -h", the syntax for this is as follows:
webpmux -frame FRAME_OPTIONS [-frame...] [-loop LOOP_COUNT] [-bgcolor BACKGROUND_COLOR] -o OUTPUT
Where each 'FRAME_OPTIONS' is of the form:
file_i +di[+xi+yi[+mi]]
where: 'file_i' is the i'th animation frame (WebP format),
'di' is the pause duration before next frame.
'xi','yi' specify the image offset for this frame.
'mi' is the dispose method for this frame (0 or 1).
And the arguments shown in the square brackets are optional.
An example command-line would be:
webpmux -frame 01.webp +100 -frame 02.webp +200 -frame 03.webp +300+10+20 -o test.webpThis would create an animation with 3 frames:
- 1st frame has a duration of 100 ms and other options are default
- 2nd frame has a duration of 200 ms and other options are default.
- 3rd frame has a duration of 300 ms, X-offset of 10 pixels and Y-offset of 20 pixels.

That's a good suggestion, thanks for the reminder.
Actually, these _is_ a test-suite repository libwebp-test-data.
It is listed here http://www.webmproject.org/code/.
(browse: )
I recently added some lossy + lossless cases, but i agree it's quite incomplete for now.
I've just sent a patch with a lot of new test vector for lossless format:
that contain all lossless's spec feature combinations.
I'll add some more with metadata, animation, etc. soon.

(2) Now, create an animated WebP image, from multiple WebP images created in step 1, using 'webpmux' binary.For example, suppose you want to create an animation from 1.webp, 2.webp, 3.webp & 4.webp where- Duration (in milliseconds) between frames is 100, 200, 300 & 400 respectively.- Animation loops 1000 times- Each frame has image offset (0,0) [that is, the top left pixel of each frame is located at (0,0)].You can use the following command to achieve this:
webpmux -frame 1.webp +0+0+100 -frame 2.webp +0+0+200 -frame 3.webp +0+0+300 -frame 4.webp +0+0+400 -loop 1000 -o animation.webp
Hope this helps.-Urvang

Hi!
From what I read webp supports animation. Given a set of X jpg images
how can I convert them to an animated webp?

Hi, Is there a way to make an animated .webp from thousands of files? I made a python script that uses the command line tools but the command line gets very long (I am trying to make a 1800 frame animation) and I always get a long command line error.
This use case is exactly why most of the webp tools can take a single text file as sole argument!
For instance, you can put the arguments into a single text file and pass this file's name to webpmux.
Here's what 'webpmux -h' has to say:
[...]
Note: if a single file name is passed as the argument, the arguments will be
tokenized from this file. The file name must not start with the character '-'.
tokenized from this file. The file name must not start with the character '-'.
And same for 'img2webp' tool:
[...]
img2webp compresses a sequence of images using the animated WebP format. Input images can either be PNG, JPEG, TIFF or WebP. If a
single file name (not starting with the character '-') is supplied as the argument, the command line argument are actually tokenized
from this file. This allows for easy scripting or using large number of arguments.
