From 74617389c88ccf630b8cce4b54d9e2fa5afb2259 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Fri, 16 Sep 2011 23:31:48 +0200 Subject: output_plugin: the plugin allocates the audio_output object Pass audio_output objects around instead of void pointers. This will give some more control to the plugin, and prepares for non-blocking audio outputs. --- src/output/openal_output_plugin.c | 36 +++++++++++++++++++++--------------- 1 file changed, 21 insertions(+), 15 deletions(-) (limited to 'src/output/openal_output_plugin.c') diff --git a/src/output/openal_output_plugin.c b/src/output/openal_output_plugin.c index 56afc4463..1473659f0 100644 --- a/src/output/openal_output_plugin.c +++ b/src/output/openal_output_plugin.c @@ -39,6 +39,8 @@ #define NUM_BUFFERS 16 struct openal_data { + struct audio_output base; + const char *device_name; ALCdevice *device; ALCcontext *context; @@ -126,10 +128,8 @@ openal_unqueue_buffers(struct openal_data *od) } } -static void * -openal_init(G_GNUC_UNUSED const struct audio_format *audio_format, - const struct config_param *param, - G_GNUC_UNUSED GError **error) +static struct audio_output * +openal_init(const struct config_param *param, GError **error_r) { const char *device_name = config_get_block_string(param, "device", NULL); struct openal_data *od; @@ -139,24 +139,30 @@ openal_init(G_GNUC_UNUSED const struct audio_format *audio_format, } od = g_new(struct openal_data, 1); + if (!ao_base_init(&od->base, &openal_output_plugin, param, error_r)) { + g_free(od); + return NULL; + } + od->device_name = device_name; - return od; + return &od->base; } static void -openal_finish(void *data) +openal_finish(struct audio_output *ao) { - struct openal_data *od = data; + struct openal_data *od = (struct openal_data *)ao; + ao_base_finish(&od->base); g_free(od); } static bool -openal_open(void *data, struct audio_format *audio_format, +openal_open(struct audio_output *ao, struct audio_format *audio_format, GError **error) { - struct openal_data *od = data; + struct openal_data *od = (struct openal_data *)ao; od->format = openal_audio_format(audio_format); @@ -198,9 +204,9 @@ openal_open(void *data, struct audio_format *audio_format, } static void -openal_close(void *data) +openal_close(struct audio_output *ao) { - struct openal_data *od = data; + struct openal_data *od = (struct openal_data *)ao; timer_free(od->timer); alcMakeContextCurrent(od->context); @@ -211,10 +217,10 @@ openal_close(void *data) } static size_t -openal_play(void *data, const void *chunk, size_t size, +openal_play(struct audio_output *ao, const void *chunk, size_t size, G_GNUC_UNUSED GError **error) { - struct openal_data *od = data; + struct openal_data *od = (struct openal_data *)ao; ALuint buffer; ALint num, state; @@ -257,9 +263,9 @@ openal_play(void *data, const void *chunk, size_t size, } static void -openal_cancel(void *data) +openal_cancel(struct audio_output *ao) { - struct openal_data *od = data; + struct openal_data *od = (struct openal_data *)ao; od->filled = 0; alcMakeContextCurrent(od->context); -- cgit v1.2.3
