Function Documentation

decode_rtp_packet()

size_t decode_rtp_packet	(	rtp_packet_t *	rp,
		SAMPLE **	out_buff,
		GHashTable *	decoders_hash,
		unsigned *	channels_ptr,
		unsigned *	sample_rate_ptr
	)

Decode an RTP packet

Parameters

rp	Wrapper for per-packet RTP tap data.
out_buff	Output audio samples.
decoders_hash	Hash table created with rtp_decoder_hash_table_new.
channels_ptr	If non-NULL, receives the number of channels in the sample.
sample_rate_ptr	If non-NULL, receives the sample rate.

Returns

The number of decoded bytes on success, 0 on failure.

rtp_decoder_hash_table_new()

GHashTable * rtp_decoder_hash_table_new

(

void

)

Create a new hash table.

Returns

A new hash table suitable for passing to decode_rtp_packet.
