Data Fields
gint	rid_ext_id
	RTP Stream extension ID, if any.
janus_av1_svc_context	av1_context [3]
	Dependency Descriptors contexts, if any.
int	substream
	Which simulcast substream we should forward back.

	As above, but to handle transitions (e.g., wait for keyframe)
guint32	drop_trigger
	How much time (in us, default 250000) without receiving packets will make us drop to the substream below.

	When we relayed the last packet (used to detect when substreams become unavailable)
gboolean	changed_substream
	Whether the substream has changed after processing a packet.
gboolean	changed_temporal

Field Documentation

av1_context

janus_av1_svc_context janus_rtp_simulcasting_context::av1_context[3]

Dependency Descriptors contexts, if any.

changed_substream

gboolean janus_rtp_simulcasting_context::changed_substream

Whether the substream has changed after processing a packet.

changed_temporal

gboolean janus_rtp_simulcasting_context::changed_temporal

Whether the temporal layer has changed after processing a packet.

drop_trigger

guint32 janus_rtp_simulcasting_context::drop_trigger

How much time (in us, default 250000) without receiving packets will make us drop to the substream below.

last_relayed

gint64 janus_rtp_simulcasting_context::last_relayed

When we relayed the last packet (used to detect when substreams become unavailable)

need_pli

gboolean janus_rtp_simulcasting_context::need_pli

substream

int janus_rtp_simulcasting_context::substream

Which simulcast substream we should forward back.

substream_target

int janus_rtp_simulcasting_context::substream_target

templayer

int janus_rtp_simulcasting_context::templayer
