NAME
al_play_audio_stream - Allegro 5 API
SYNOPSIS
#include <allegro5/allegro_audio.h>
ALLEGRO_AUDIO_STREAM *al_play_audio_stream(const char *filename)
DESCRIPTION
Loads and plays an audio file, streaming from disk as it is needed. This API can only play one audio
stream at a time. This requires a default mixer to be set, which is typically done via
al_reserve_samples(3alleg5), but can also be done via al_set_default_mixer(3alleg5).
Returns the stream on success, NULL on failure. You must not destroy the returned stream, it will be
automatically destroyed when the addon is shut down.
Note: the allegro_audio library does not support any audio file formats by default. You must use
the allegro_acodec addon, or register your own format handler.
