Bug#726912: libsdl-mixer1.2: Music with TiMidity backend plays too fast

[Sylvain Beucler]

Package: libsdl-mixer1.2
Version: 1.2.12-9
Severity: normal

Hi,

I noticed that the new SDL-Mixer has fluidsynth support, but it
doesn't play all midi files properly. Note: this is a limitation in
fluidsynth afaics, e.g. with 'freedink-data',
  fluidsynth -a alsa -l -i /usr/share/sounds/sf2/FluidR3_GM.sf2 /usr/share/games/dink/dink/Sound/104.mid
just fails.

So I tried falling back to the TiMidity backend, but with:
  /usr/src/sdl-mixer1.2-1.2.12/build$ SDL_FORCE_SOUNDFONTS=1 SDL_SOUNDFONTS= ./playmus /usr/share/games/dink/dink/Sound/104.mid
the music files are played way faster than normal.
Same issue when played from within the 'freedink' game.

You can compare with timidity+freepats:
  timidity /usr/share/games/dink/dink/Sound/104.mid
or more importantly with an upstream build of SDL 1.2.12:
  /usr/src/SDL_mixer-1.2.12/build$ ./playmus /usr/share/games/dink/dink/Sound/104.mid

So it looks like a Debian-patch messed with the TiMidity backend.

Cheers!
Sylvain
