Function Documentation

parse_encoding()

bool roc::rtp::parse_encoding	(	const char *	str,
		Encoding &	result
	)

Parse RTP encoding from string.

Remarks

The input string should have the form:

• "<id>:<spec>"

Where:

• "<id>" is payload id, a positive integer
• "<spec>" is sample spec, in form "<format>/<rate>/<channel>"

See audio::parse_sample_spec() for details on "<spec>" format.

Examples:

• "55:s16/44100/stereo"
• "77:f32/96000/20-30"

Returns

false if string can't be parsed.
