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
