[PATCH 0/5] Support fluidsynth and opus in sdl(2)-mixer, and other tweaks |
|

Hi,
these patches improve sdl- and sdl2-mixer: fix dependencies and
configure flags that changed between the two versions, and enable
support for fluidsynth and opus libraries. I tested several dependent
packages, and everything seems to work OK.
The MIDI backends need additional runtime configuration. Fluidsynth
requires a soundfont to be installed and specified when running a
program that uses sdl-mixer, e.g.:
SDL_SOUNDFONTS=/gnu/store/…-fluid-3-2.1/share/soundfonts/FluidR3Mono_GM.sf3
If this is not set, the bundled timidity backend is used, which can use
the freepats samples. Configuration must be specified since only files
under /etc are checked by default, e.g.:
TIMIDITY_CFG=/gnu/store/…-freepats-20060219/share/freepats/freepats.cfg
I’m not sure if and how default values for these vars can be specified
for all programs using sdl-mixer, and I would prefer to leave the choice
of backend to the user anyway. However, we should probably document them
somewhere. Would a comment be enough? Dependent packages can then wrap
binaries to set required paths if needed.
Alternatively we can add freepats and/or fluid as inputs to sdl(2)-mixer
and patch the source to look for them in the store.
Thanks!
