Rendering to WEBP with Loop set to 0 doesn't loop infinitely

    I wanted to render a small inifinitely looping animation into a WEBP but when setting "loop" to 0 it is not ending up looping infinitely.
    I'm not sure if this is an ffmpeg bug and it'd need a new build or if something isn't being passed correctly.

    Trying to convert an e.g. WEBM to an animated WEBP via. the command line in ffmpeg it works fine
    Example arguments:

    Code
    ffmpeg -i video.webm -loop 0 output.webp

    (Alternatively even

    Code
    "C:\Program Files\FFmpeg\ffmpeg.exe" -i video.webm -loop 0 output.webp

    As an extra test I even tried using `LIBWEBP`instead of `LIBWEBP_ANIM` but the result is the same, it doesn't want to loop infinitely
