-Subject: [PATCH] build: fix dynamic generation of mpv.desktop file protocols
-
-Running cross-compiled binaries may be possible, but the runtime
-environment must be configured correctly. In some configurations, an
-exe_wrapper needs to be used, and in all cases, the library path must be
-set correctly for the given binary. Fortunately, Meson handles all of
-this if cross-compilation is configured correctly.
-
-Fix this by having Meson run the mpv binary directly, instead of as a
-subprocess of a Python script. This ensures that the environment is
-properly set for running host binaries, if possible.
-
-Fixes: #15075
-Fixes: 056b03f9ed05607786427da8f336e3ef819b3a1e
