Detailed Description

Definitions for audio capture and encoding.

Function Documentation

get_audio_ctx_ref()

audio_ctx_ref_t audio::get_audio_ctx_ref

(

)

Get the reference to the audio context.

Returns

A shared pointer reference to audio context.

Note

Aside from the configuration purposes, it can be used to extend the audio sink lifetime to capture sink earlier and restore it later.

Examples

audio_ctx_ref_t audio = get_audio_ctx_ref()

is_audio_ctx_sink_available()

bool audio::is_audio_ctx_sink_available

(

const audio_ctx_t &

ctx

)

Check if the audio sink held by audio context is available.

Returns

True if available (and can probably be restored), false otherwise.

Note

Useful for delaying the release of audio context shared pointer (which tries to restore original sink).

Examples

audio_ctx_ref_t audio = get_audio_ctx_ref()
if (audio.get()) {
    return is_audio_ctx_sink_available(*audio.get());
}
return false;
