Animated WEBP image format support?
Posted: Thu Jun 04, 2020 2:58 pm
Hello!
Recently i found that XnView MP cannot show me animated images with WEBPVP8X ANIM ANMF headers. This format is quite popular on, ahem, very interesting sites.
I have decided to go deeper and converted one GIF to Animated WebP format using the first site i found https://ezgif.com/webp-maker and here are my results.
So far i tested these settings, and XnView MP cannot show none of these WEBP animations, not even a single frame:
https://ezgif.com/gif-to-webp lossy-flag-off (VP8L - lossless)
RIFFBWEBPVP8X
ANIMLRUÿANMF¢,VP8L
https://ezgif.com/gif-to-webp lossy-flag-on (VP8 - PNG-like format?)
RIFF0WEBPVP8X
ANIMLRUÿANMF4,VP8
https://ezgif.com/gif-to-webp mixed-flag-on (i dont know why, but it produces files that are binary identical to lossy-flag-off)
https://ezgif.com/webp-maker/ webp-maker-no-flags (VP8 - JPEG-like format?)
RIFF8JWEBPVP8X
ANIMÿÿÿÿANMFB,VP8
You can download these WEBP sample files in Attachments section, since this forum does not allow me to upload them
Also you can open all of these WEBP samples in the latest stable versions of Mozilla Firefox and Google Chrome browsers. So it must be related some kind of image library, right?
Please, can you change/update that image library in XnView MP to support animated WEBP image format(s)?
