[FFmpeg-devel] [RFC] webp decoding

Hi

some people use webp apparently, and we have no decoder

There are 2 patchsets
Thilos v13 (native decoder)
Peters libwebp based one

I tested both and thilos code decodes the files from the 4709 ticket
i was not able to decode anything with peters patch. Iam not sure it
needs some demuxer changes that are missing it also didnt work with
the demuxer chanegs from thilos pacthset.

What i suggest is ... can we just apply thilos patchset ?

what do people think about that idea ?

It does have a review comment about use of nested decoders and direct
rendering not working. But honestly. That decoder (maybe marked as
experimental?) seems better than having no decoder

Do we have someone willing to work on webp ?
(Iam pretty sure we can fund that work someehow if interrest is conditional on US$)
Or is someone even already working on it ?

thx

libavcodec/webp.c is a decoder.
