WebP Image Support
#1
Hi,

i converted my whole image libraries to WebP some month ago to save space and it would be nice to get them watchable using Kodi. However, even if i add .webp to pictureextensions in advancedsettings.xml all i get is a black screen.

Tried on 14.2 Windows and OpenELEC.

Thank you,
Hawk

How much space did you save?

most likely around 30%.

But webp isn't supported . However, adding decoding support should be easy. Probably only activating it's extension since the needed dependencies already support webp for a long time.

I just tried that. They are listed by the file browser then but aren't decoded.

Never assume a change is easy without knowing the codebase inside out, it's not helpful to the conversation and it can trigger a bit of hostility sometimes.

AFAIK we have our own imagelib and I haven't seen any webp support in it, adding support would likely require a fair bit of work.

What dependencies are you referring to that already has the support needed?

I think he was referring to ffmpeg.

How big is this "fair bit of work". Has it a real chance? Can i support in any way?

the way to do this is to add a ffmpeg based image loader. you then get webp and a shitload of image formats. and cximage can then die in a horrible fire.

it's simple. Why do you suggest otherwise?
pr for webp is there: https://github.com/xbmc/xbmc/pull/8370
but will not be commited before Jarvis is branched.

there could be an estimated speed improvement due to ~30% smaller files. But that's if decoder has the same speed to read all data into memory.
