Streamer

Description

Wrapper for media streaming functionality (audio via GStreamer).

Collaboration diagram for Streamer:

Enumerations
enum	EStreamerState { strOff = 0 , strError , strBusy , strOn }
	State of the streamer. More...

Functions
static bool	StreamerStateIsActive (EStreamerState s)
	Active states are those requiring eventual calls to 'StreamerIterate'. 'StreamerStop' reliably switches to an inactive state.
const char *	StreamerGetError (CString *s)
	Return readable error message and reset the text internally.
int	StreamerGetDbLevel ()
	Return the current level in DB (<= 0, 0 = maximum) or STREAMER_LEVEL_UNKNOWN (= -INT_MAX / very, very silent), if the level is unknown. More...

Function Documentation

StreamerGetDbLevel()

int StreamerGetDbLevel

(

)

Return the current level in DB (<= 0, 0 = maximum) or STREAMER_LEVEL_UNKNOWN (= -INT_MAX / very, very silent), if the level is unknown.

Level measurement is activated by the first call to this function, and deactivated again in 'StreamerStop ()'. The first call will most probably return STREAMER_LEVEL_UNKNOWN. When activated, additional CPU load and power consumption may occur.
