1.1.41.3-beta JPEGView AVIF support (beta)

Experimental AVIF image format support - BETA

• Add experimental AVIF image format support.
  • Note: there's a new avif.dll you need to add to your installation.
  • Can view animated AVIF - you may try the attached sample animated AVIF image.
    • Bug fix: read correct animated AVIF frame interval.
  • Can now save as AVIF
    • Can now save animated image as animated AVIF too.
    • Lossy (quality:60) or lossless - select via file extension filter.
  • Tested on more sample images from link-u/avif-sample-images
    • Fixed viewing of higher bpp (e.g. 10bpp) AVIF images. Via downgrade to 8bpp.
    • Fixed opening of AVIF image with unicode filenames (standalone JPEGView.exe only for testing).
    • known issues:
      • fail to load 'crop' images. Likely owing to BMFF parse failure.
      • sometimes switching images rapidly to a AVIF causes load failure of the image.

Download

• JPEGView.exe - latest EXE able to open AVIF image with unicode filenames, save as animated AVIF. This EXE is newer than the ones in the ZIP files.
• JPEGView.zip - full, portable package, you may unzip and run from.
• JPEGView-less-config.zip - for updating existing installation; just unzip and replace EXE & DLLs.
  • Merge any new config option(s) yourself.

PS: binaries are from newer codes than the tagged source
