Detailed Description

RTP payload type operations.

This structures contains the callbacks provided by an RTP payload type (vlc_rtp_pt).

Field Documentation

decode

void(* vlc_rtp_pt_operations::decode) (struct vlc_rtp_pt *pt, void *data, block_t *block, const struct vlc_rtp_pktinfo *restrict info)

Processes a data payload.

Parameters

pt	RTP payload type of the payload
data	data pointer returned by init()
block	payload of a received RTP packet
info	RTP packet header infos

Referenced by vlc_rtp_pt_decode().

destroy

void(* vlc_rtp_pt_operations::destroy) (struct vlc_rtp_pt *pt, void *data)

Stops using a payload type.

This optional callback deinitialises per-source resources.

Parameters

pt	RTP payload type to relinquish
data	data pointer returned by init()

Referenced by vlc_rtp_pt_end().

init

void *(* vlc_rtp_pt_operations::init) (struct vlc_rtp_pt *pt)

Starts using a payload type.

This required callback initialises per-source resources for the payload type, such as an elementary stream output.

Note

There may be multiple RTP sources using the same payload type concurrently within single given RTP session. This callback is invoked for each source.

Parameters

pt	RTP payload type being taken into use

Returns

a data pointer for decode() and destroy() callbacks

Referenced by vlc_rtp_pt_begin().

release

void(* vlc_rtp_pt_operations::release) (struct vlc_rtp_pt *pt)

Releases the payload type.

This optional callback releases any resources associated with the payload format, such as copies of the payload format parameters.

Parameters

pt	RTP payload type that is being released
