php 8.1 avif error (docker): No codec available

I have php 8.1 via docker and avif functions not working.

Warning: imageavif(): avif error - Could not encode image: No codec available in /var/www/test.php on line 5

Dockerfile:

FROM php:8.1-fpm

    git \

My test.php:

<?php

ini_set('display_errors', 1);

var_dump(imageavif(imagecreatetruecolor(8, 8), "/tmp/test")); // true
var_dump(file_get_contents("/tmp/test")); // empty string
die();
Solution

  • Rewrote Dockerfile like this:

    FROM php:8.1-fpm

ADD https://github.com/mlocati/docker-php-extension-installer/releases/latest/download/install-php-extensions /usr/local/bin/
RUN chmod +x /usr/local/bin/install-php-extensions && \
    install-php-extensions gd
