[FFmpeg-devel] [PATCH v2 0/5] webp: add support for animated WebP decoding

[Thilo Borgmann]

Now includes the demuxer again. Absence of the demuxer caused wrong
framerate detection. We are promised a review of the demuxer code as
well so it shall not rotten again with the remaining patches. Also adds
loop control suggested in v1.

This makes it feasable again to move some definitions into a shared
header which was nak'd in v1.

Patch 4/5 is still there for making changes in lavc/webp reviewable but
shall be stashed when pushing.

The remaining rendering issue is still worked on though we are not yet
sure how to fix it because of missing reference. The good news is that this
patchset already does a better rendering than libwebp v1.3.1 on the
problematic file. Haven't lost hope that this can yet be improved,
though.
