| struct GrooveAudioFormat GrooveSink::audio_format |
set this to the audio format you want the sink to output
| int GrooveSink::buffer_sample_count |
If you leave this to its default of 0, frames pulled from the sink will have sample count determined by efficiency.
If you set this to a positive number, frames pulled from the sink will always have this number of samples.
| int GrooveSink::buffer_size |
how big the buffer queue should be, in sample frames.
groove_sink_create defaults this to 8192
| int GrooveSink::bytes_per_sec |
read-only.
automatically computed from audio_format when you call groove_sink_attach
| int GrooveSink::disable_resample |
Set this flag to ignore audio_format.
If you set this flag, the buffers you pull from this sink could have any audio format.
| void(* GrooveSink::flush)(struct GrooveSink *) |
called when the audio queue is flushed.
For example, if you seek to a different location in the song.
| double GrooveSink::gain |
This volume adjustment only applies to this sink.
It is recommended that you leave this at 1.0 and instead adjust the gain of the playlist. If you want to change this value after you have already attached the sink to the playlist, you must use groove_sink_set_gain. float format. Defaults to 1.0
| void(* GrooveSink::pause)(struct GrooveSink *) |
called when the playlist is paused
| void(* GrooveSink::play)(struct GrooveSink *) |
called when the playlist is played
| struct GroovePlaylist* GrooveSink::playlist |
read-only.
set when you call groove_sink_attach. cleared when you call groove_sink_detach
| void(* GrooveSink::purge)(struct GrooveSink *, struct GroovePlaylistItem *) |
called when a playlist item is deleted.
Take this opportunity to remove all your references to the GroovePlaylistItem.
| void* GrooveSink::userdata |
set to whatever you want, defaults to NULL.
