WebP Encoding

Warning: in recent versions, the cython webp module has been disabled because of a conflict between the library we link against and the library that pillow is build against, see #1064

This Encoding has 2 encoders and decoders:

• a Cython based one, which uses the ​Advanced Encoding API which is faster
• fallback to wiki/Encodings/Pillow

Versions

As of xpra version 2.2, we no longer support older version of libwebp, you must have version 0.5 or later.
