Initializing PipeWire and loading SPA modules.
◆ pw_init()
void pw_init |
( |
int * |
argc, |
|
|
char ** |
argv[] |
|
) |
| |
Initialize PipeWire.
- Parameters
-
argc | pointer to argc |
argv | pointer to argv |
Initialize the PipeWire system, parse and modify any parameters given by argc and argv and set up debugging.
This function can be called multiple times.
- Examples
- audio-capture.c, audio-dsp-filter.c, audio-dsp-src.c, audio-src.c, bluez-session.c, export-sink.c, export-source.c, export-spa-device.c, export-spa.c, internal.c, local-v4l2.c, tutorial1.c, tutorial2.c, tutorial3.c, tutorial4.c, tutorial5.c, tutorial6.c, video-dsp-play.c, video-play-fixate.c, video-play-pull.c, video-play-reneg.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.
◆ pw_deinit()
Deinitialize PipeWire.
Deinitialize the PipeWire system and free up all resources allocated by pw_init().
Before 0.3.49 this function can only be called once after which the pipewire library can not be used again. This is usually called by test programs to check for memory leaks.
Since 0.3.49 this function must be paired with an equal amount of pw_init() calls to deinitialize the PipeWire library. The PipeWire library can be used again after being deinitialized with a new pw_init() call.
- Examples
- audio-capture.c, audio-dsp-filter.c, audio-dsp-src.c, audio-src.c, internal.c, local-v4l2.c, video-play-fixate.c, video-play-pull.c, video-play-reneg.c, video-play.c, video-src-alloc.c, video-src-fixate.c, video-src-reneg.c, and video-src.c.
◆ pw_debug_is_category_enabled()
bool pw_debug_is_category_enabled |
( |
const char * |
name | ) |
|
Check if a debug category is enabled.
- Parameters
-
name | the name of the category to check |
- Returns
- true if enabled
Debugging categories can be enabled by using the PIPEWIRE_DEBUG environment variable
◆ pw_get_application_name()

( |
void |
| ) |
|
Get the client name.
