The GstRTPCBuffer helper functions makes it easy to parse and create regular
#GstBuffer objects that contain compound RTCP packets. These buffers are typically
of 'application/x-rtcp' #GstCaps.

An RTCP buffer consists of 1 or more #GstRTCPPacket structures that you can
retrieve with gst_rtcp_buffer_get_first_packet(). #GstRTCPPacket acts as a pointer
into the RTCP buffer; you can move to the next packet with
gst_rtcp_packet_move_to_next().</doc>

      <doc xml:space="preserve">Provides a base class for audio RTP payloaders for frame or sample based
audio codecs (constant bitrate)

This class derives from GstRTPBasePayload. It can be used for payloading
audio codecs. It will only work with constant bitrate codecs. It supports
both frame based and sample based codecs. It takes care of packing up the
audio data into RTP packets and filling up the headers accordingly. The
payloading is done based on the maximum MTU (mtu) and the maximum time per
packet (max-ptime). The general idea is to divide large data buffers into
smaller RTP packets. The RTP packet size is the minimum of either the MTU,
max-ptime (if set) or available data. The RTP packet size is always larger or
equal to min-ptime (if set). If min-ptime is not set, any residual data is
sent in a last RTP packet. In the case of frame based codecs, the resulting
RTP packets always contain full frames.

## Usage

To use this base class, your child element needs to call either
gst_rtp_base_audio_payload_set_frame_based() or
gst_rtp_base_audio_payload_set_sample_based(). This is usually done in the
element's `_init()` function. Then, the child element must call either
gst_rtp_base_audio_payload_set_frame_options(),
gst_rtp_base_audio_payload_set_sample_options() or
gst_rtp_base_audio_payload_set_samplebits_options. Since
GstRTPBaseAudioPayload derives from GstRTPBasePayload, the child element
must set any variables or call/override any functions required by that base
class. The child element does not need to override any other functions
specific to GstRTPBaseAudioPayload.</doc>

with the amount of data in each input buffer, consider e.g. the case where
the buffer arrives from a network which means that the PTS is unrelated to
the amount of data. Because the RTP timestamps are generated from
GST_BUFFER_PTS this can result in RTP timestamps that also don't increment
with the amount of data in the payloaded packet. To circumvent this it is
possible to set the perfect rtptime option enabled. When this option is
enabled the payloader will increment the RTP timestamps based on
GST_BUFFER_OFFSET which relates to the amount of data in each packet
rather than the GST_BUFFER_PTS of each buffer and therefore the RTP
timestamps will more closely correlate with the amount of data in each
buffer. Currently GstRTPBasePayload is limited to handling perfect RTP
timestamps for audio streams.</doc>
