When exiting a level, music.init() gets called again, and every time it
gets called after the first time it gets called, it will free all music
tracks.
To do so, it calls Mix_FreeMusic(). Unfortunately, if there is music
fading, Mix_FreeMusic() will call SDL_Delay(), which will result in
annoying no-draw frames. Meaning, the screen freezes and doesn't draw
anything, and has to wait a bit before continuing.
Here's the relevant piece of code from SDL2_mixer's music.c:
if (music == music_playing) {
/* Wait for any fade out to finish */
while (music->fading == MIX_FADING_OUT) {
Mix_UnlockAudio();
SDL_Delay(100);
Mix_LockAudio();
}
if (music == music_playing) {
music_internal_halt();
}
}
This is especially annoying if you're a TASer, because no-draw frames in
a libTAS movie aren't guaranteed to last for a consistent number of
frames when you change your inputs around.
After this patch, as long as your computer can unmount and re-mount
assets fast enough (it doesn't seem like mine can, unfortunately), then
you won't get any freezes when exiting a level that has custom assets.
(This freeze didn't happen when loading a level because the title screen
music fadeout upon pressing ACTION had enough time to fully complete
before the level got loaded.)
