How can I decode webp image on Java? #18

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
In my opinion, webp is most useful on mobile network application, for the 
wirlesss network speed is so low.

But it seems not easy to implement decoding on Java platform such as j2me for I 
haven't found anything about Java version of VP8 decoder.

Is there anyone know more about it? 

Thank you for your advice in advance.

I wont be using WebP for my projects at least until a Java library is completed.
Also when will Android be getting support?

There is a partially working Java VP8 decoder available at 
http://sourceforge.net/projects/javavp8decoder/ I hope to complete some day. It 
is currently a bit of a mess but it can decode enough to be useful for WebP 
decoding with a little work.

Hi Brooss,I downloaded and viewed your source code before. It seemed far to 
complete. Maybe it's very hard for java's calculation ability is limited. I'm 
not sure how fast the java vp8 decoder can be.
Maybe jni is a better choice. What do you think?

There is now a complete WebP ImageIO plugin available on the javavp8decoder 
project page. Speed isn't too bad for small to medium sized images. Check the 
demo at javavp8decoder.sf.net

HI Brooss,is the demo made by applet? it seems a little slow on IE. Could you 
share the source code?
I want to check the performence on mobile, and maybe I can do something to 
improve its performance.

All the source is available. I Didn't write the demo applet ( 
http://ian.goldby.net/justslides/ ), it's able to load WebP Images just like 
other formats once the ImageIo WebP plugin is loaded. The code for the ImageIo 
plugin is available in sourceforge git.

It would be great if someone could doing some testing on mobile devices.

I think we should close this one as fixed. Broos' solution works well. feel 
free to reopen
