codecs-php

In-process AVIF and JPEG-XL image decoding, encoding, and header probing for PHP 8.3+, backed by statically linked builds of libavif and libjxl.

• Self-contained single .so — vendored codec libraries linked with a symbol version script that exports only get_module; no system libavif/libjxl packages or ImageMagick/GD delegates required.
• In-process — no shell_exec to CLI binaries, no temporary files, and no FFI runtime requirement.
• Multi-ABI — targets PHP 8.3, 8.4, and 8.5 (PIE type: php-ext).

Requirements

• PHP 8.3, 8.4, or 8.5 (NTS or ZTS)
• Linux x86_64 / aarch64
