RIFF is a container format used for various Microsoft multimedia formats like WAV and AVI with various other uses and derivatives. The magic number is "RIFF" encoded using US-ASCII at the beginning of a file. Making "WebP", Google felt that using RIFF as container format is a good idea. http://lists.w3.org/Archives/Public/www-archive/2011Mar/0002.html As far as I am aware, Google failed to understand and implement RIFF as specified and you cannot actually parse and generate "WebP" images as if they were RIFF containers. This kind of screw-up (if it is indeed one, my analysis may well be incorrect) is perfectly normal and expected, and it's not hard to come up with all sorts of similar problems, like people re-using GUIDs when they should not, in all sorts of contexts. -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Am Badedeich 7 · Telefon: +49(0)160/4415681 · http://www.bjoernsworld.de 25899 Dagebüll · PGP Pub.
