[package] ffmpeg/7.0.1: MSYS2 MinGW-w64: OpenH264 and dav1d compilation failure (nasm)

[olekolek1000]

Description

Installing ffmpeg with with_openh264=True or with_libdav1d=True causes nasm-related compilation failure.

Interestingly, nasm is properly detected by Meson: Program nasm found: YES.

Package and Environment Details

• Package Name/Version: ffmpeg/7.0.1
• Operating System+version: Windows 11, MSYS2 MinGW-w64
• Compiler+version: GCC 14.2.0
• Conan version: conan 2.6.0
• Python version: Python 3.11.9

Conan profile

Host profile: [settings] arch=x86_64 build_type=Release compiler=gcc compiler.cppstd=gnu17 compiler.libcxx=libstdc++11 compiler.version=14 os=Windows

Build profile: [settings] arch=x86_64 build_type=Release compiler=gcc compiler.cppstd=gnu17 compiler.libcxx=libstdc++11 compiler.version=14 os=Windows

QUICK UPDATE: Can be temporarily fixed by copying nasm.exe to nasm in C:\Users\user\.conan2\p\nasm82fc2c9a305c1\p\bin.

Further configuration steps are failing anyways, like not finding openh264 via pkg-config.
