Namespaces:

RTCP

Structs:

Buffer - Note: The API in this module is not yet declared stable.
Packet - Data structure that points to a packet at offset in buffer.

Enums:

FBType - Different types of feedback messages.
SDESType - Different types of SDES content.
Type - Different RTCP packet types.
XRType - Types of RTCP Extended Reports, those are defined in RFC 3611 and other RFCs according to the [IANA registry](https://www.

Constants:

public const int MAX_BYE_SSRC_COUNT
The maximum amount of SSRCs in a BYE packet.
public const int MAX_RB_COUNT
The maximum amount of Receiver report blocks in RR and SR messages.
public const int MAX_SDES
The maximum text length for an SDES item.
public const int MAX_SDES_ITEM_COUNT
The maximum amount of SDES items.
public const int REDUCED_SIZE_VALID_MASK
Mask for version and packet type pair allowing reduced size packets, basically it accepts other types than RR and SR
public const int VALID_MASK
Mask for version, padding bit and packet type pair
public const int VALID_VALUE
Valid value for the first two bytes of an RTCP packet after applying VALID_MASK to them.
public const int VERSION
The supported RTCP version 2.

Methods:

public bool buffer_map (Buffer buffer, MapFlags flags, Buffer rtcp)
public Buffer buffer_new (uint mtu)
public Buffer buffer_new_copy_data (uint8[] data)
public Buffer buffer_new_take_data (uint8[] data)
public bool buffer_validate (Buffer buffer)
public bool buffer_validate_data (uint8[] data)
public bool buffer_validate_data_reduced (uint8[] data)
public bool buffer_validate_reduced (Buffer buffer)
public uint64 ntp_to_unix (uint64 ntptime)
Converts an NTP time to UNIX nanoseconds.
public uint64 unix_to_ntp (uint64 unixtime)
Converts a UNIX timestamp in nanoseconds to an NTP time.

Classes:

BaseAudioPayload - Provides a base class for audio RTP payloaders for frame or sample based audio codecs (constant bitrate)
BaseDepayload - Provides a base class for RTP depayloaders
BasePayload - Provides a base class for RTP payloaders
HeaderExtension - Instance struct for a RTP Audio/Video header extension.

Structs:

Buffer - The GstRTPBuffer helper functions makes it easy to parse and create regular Buffer objects that contain RTP payloads.
PayloadInfo - Structure holding default payload type information.
SourceMeta - Meta describing the source(s) of the buffer.

Enums:

BufferFlags - Additional RTP buffer flags.
BufferMapFlags - Additional mapping flags for map.
HeaderExtensionDirection - Direction to which to apply the RTP Header Extension
HeaderExtensionFlags - Flags that apply to a RTP Audio/Video header extension.
Payload - Standard predefined fixed payload types.
Profile - The transfer profile to use.

public const string HDREXT_ELEMENT_CLASS
Constant string used in element classification to signal that this element is a RTP header extension.
public const string HDREXT_NTP_56
public const int HDREXT_NTP_56_SIZE
public const string HDREXT_NTP_64
public const int HDREXT_NTP_64_SIZE
public const string HEADER_EXTENSION_URI_METADATA_KEY
