Hello.
I'd like to ask how to completely stop playback using alsa synth.
Basically my program initialized output in the following way:
snd_seq_open()
snd_seq_set_client_name()
snd_seq_client_id()
snd_seq_parse_address()
snd_seq_create_simple_port()
snd_seq_connect_to()
snd_seq_alloc_named_queue()
Then I create a new thread that processes events.
It sets tempo and in infinite loop it does:
snd_seq_ev_set_fixed()
snd_seq_event_output()
This all is based on aplaymidi code.
How can I asynchronously immediately stop all the playback? Basicaly it
requires breaking snd_seq_event_output() thats locked on my thread.
I tried everything I could come up with. I know very little about alsa
synth programming and basically thats the only thing i need to do now.
Tried:
snd_seq_ev_set_queue_stop()
snd_seq_stop_queue()
snd_seq_remove_events()
or even closing the seq completely to reopen it on another file playback
with:
snd_seq_stop_queue()
snd_seq_disconnect_to()
snd_seq_delete_simple_port()
snd_seq_close()
All failed, results were very various. I simply run out of ideas. It
doesn't matter if the method would require to close seq or not. I just
need to stop the playback so i can gracefully stop the thread and play
another file (with eventual reopening ports/seq).
Would appreciate any help.
