void timestampOffset(uint propval) @property

gst.buffer.Buffer allocateOutputBuffer(uint payloadLen, ubyte padLen, ubyte csrcCount)Allocate a new #GstBuffer with enough data to hold an RTP packet with minimum csrccount CSRCs, a payload length of payloadlen and padding of pad_len. If payload has #GstRTPBasePayload:source-info t...

uint getSourceCount(gst.buffer.Buffer buffer)Count the total number of RTP sources found in the meta of buffer, which will be automically added by [gstrtp.rtpbase_payload.RTPBasePayload.allocateOutputBuffer]. If #GstRTPBasePayload:source-info...

bool isFilled(uint size, gst.types.ClockTime duration)Check if the packet with size and duration would exceed the configured maximum size.

bool isSourceInfoEnabled()Queries whether the payloader will add contributing sources (CSRCs) to the RTP header from #GstRTPSourceMeta. Returns: true if source-info is enabled.

gst.types.FlowReturn push(gst.buffer.Buffer buffer)Push buffer to the peer element of the payloader. The SSRC, payload type, seqnum and timestamp of the RTP buffer will be updated first.

gst.types.FlowReturn pushList(gst.buffer_list.BufferList list)Push list to the peer element of the payloader. The SSRC, payload type, seqnum and timestamp of the RTP buffer will be updated first.

void setOptions(string media, bool dynamic, string encodingName, uint clockRate)Set the rtp options of the payloader. These options will be set in the caps of the payloader. Subclasses must call this method before calling [gstrtp.rtpbasepayload.RTPBasePayload.push] or [gstrtp....

bool setOutcapsStructure(gst.structure.Structure s = null)Configure the output caps with the optional fields.

void setSourceInfoEnabled(bool enable)Enable or disable adding contributing sources to RTP packets from #GstRTPSourceMeta.
