Properties

aggregate-mode

“aggregate-mode” Rtp-h264aggregate-mode *

Bundle suitable SPS/PPS NAL units into STAP-A aggregate packets.

This can potentially reduce RTP packetization overhead but not all RTP implementations handle it correctly.

For best compatibility, it is recommended to set this to "none" (the default) for RTSP and for WebRTC to "zero-latency".

Flags : Read / Write

Default value : none (0)

Since : 1.18


config-interval

“config-interval” gint

Send SPS and PPS Insertion Interval in seconds (sprop parameter sets will be multiplexed in the data stream when detected.) (0 = disabled, -1 = send with every IDR frame)

Flags : Read / Write

Default value : 0


sprop-parameter-sets

“sprop-parameter-sets” gchararray

The base64 sprop-parameter-sets to set in out caps (set to NULL to extract from stream)

Flags : Read / Write

Default value : NULL


Named constants

Rtp-h264aggregate-mode

Members

none (0) – Do not aggregate NAL units
zero-latency (1) – Aggregate NAL units until a VCL unit is included
max-stap (2) – Aggregate all NAL units with the same timestamp (adds one frame of latency)
