Description

Follow up from #53653.

Looking at https://developers.google.com/speed/webp/docs/riff_container, the "extended" WebP file format VP8X may include a lossy or lossless "bitstream" chunk (VP8 or VP8L) and few optional chunks: ALPH, EXIF, ICCP, ANIM, etc.

Ideally the wp_get_webp_info() function should be extended to detect these features.

With 5.8.1 RC in less than 24 hours and no patch, I'm going to punt to 5.8.2.

Thankyou @sourovroy

A couple of questions
Are these royalty free images?

and what is the extra info that each image has?

We are looking for images with extra chunks of image data

I wanted to bring this to your attention:

  • Will this feature here ensure all 3 criteria as proposed in #57238 ?
  • Feel free to copy/merge the sample files and comments from there to here if appropriate.
