    Supported AVIF Image format

    Is anyone aware if AVIF support is in the works?
    I searched the forum here but didn't see any posts about it.

    There's a bunch of test images from Netflix here
    Firefox and Chromium both have open issues for adding support, and with the interest in the format I thought there should be at least one request here for the time being

    Update: I am mildly dumb, but not that dumb.

    Irfanview appears to be able to load some avif images using the Microsoft av1 extension
    however it doesn't work with the `ftypavif` header, if you edit the header to `ftypmif1` it is able to load the image just fine

    So uhh change the feature request to supporting the other header I guess

      Have you sent the feature request to Irfan Skiljan yet?
      See the IrfanView Help menu, About IrfanView for his address.

      AVIF seems to be an OpenSource format.

        I'd like to bump this up. As far as I can test, there's no functional support for AVIF reading (not to speak of writing) in IrfanView. For example this suite of test images: http://https://github.com/link-u/avif-sample-images -- none of these will be correctly opened by the most recent IrfanView version.

        The implementation should not be very difficult as reference codec library libavif is available from AOMedia.

          The plug-in (https://www.irfanview.com/plugins.htm) page says:
          • TOOLS - (version 4.56): contains some additional functions/features for IrfanView
            (and some special formats, like: HEIC, AVIF; with installed codecs/extensions)
          But cannot see AVIF in the Open or Save dialogbox.??

            In the file open dialog it lists HEIC/AVIF. You can also select All Files or All supported Graphic Files.

            IrfanView does not support the saving of all file formats; just open. It only saves common image formats.
