WebP support (2 issues)

Post by DOS386 » Mon May 02, 2016 3:49 pm

- WeBP support could be native rather than depend from a DLL

- attached WebP file can't be decoded anymore, while 2 other WebP files I have still do work, and IIRC I've seen this file displayed in XN some time ago (XN version cca 2.0xx (??) + plugin version ?? used to work)

DELETED attachment 2016-Aug-09 , see below

There is indeed no WinZIP under my rock.

Classic 2.36 with the MP 0.79 webp.dll hates it, the Babelsoft Media Preview hates it (based on a vintage 2014 FFMpeg libav), and WebP 0.5.0 dwebp.exe also hates it:

Code: Select all

Decoding of DSCN2350.WEbP failed.
Status: 7(NOT_ENOUGH_DATA)
It appears to be seriously broken.

Well, XN 1.98 + WEBP.DLL 201'728 is happy with it. And I have one more file with same problem. Later WEBP library versions do no longer accept early WEBP's.

http://samples.mplayerhq.hu/image-samples/webp (<- also evil)

webp2000.zip (10 MiO , 7 WEBP's , 2 of them evil)

It's not a bug of NC/XN, but a problem of the WEBP library.

Even with lastest Webp dll, the 3 files can't be readed. I'll check
