Data Fields
struct janus_av1_svc_context	dd_context
	Dependency Descriptor context, in case it's needed.
int	spatial
	Which SVC spatial layer we should forward back.
int	spatial_target
	As above, but to handle transitions (e.g., wait for keyframe, or get this if available)
int	temporal
	Which SVC temporal layer we should forward back.
int	temporal_target
	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.
gint64	last_spatial_layer [3]
	When we relayed the last packet (used to detect when layers become unavailable)
gboolean	changed_spatial
	Whether the spatial layer has changed after processing a packet.
gboolean	changed_temporal
	Whether the temporal layer has changed after processing a packet.
gboolean	need_pli
	Whether we need to send the user a keyframe request (PLI)

Detailed Description

Helper struct for processing and tracking VP9-SVC streams.

Field Documentation

changed_spatial

gboolean janus_rtp_svc_context::changed_spatial

Whether the spatial layer has changed after processing a packet.

changed_temporal

gboolean janus_rtp_svc_context::changed_temporal

Whether the temporal layer has changed after processing a packet.

dd_context

struct janus_av1_svc_context janus_rtp_svc_context::dd_context

Dependency Descriptor context, in case it's needed.

drop_trigger

guint32 janus_rtp_svc_context::drop_trigger
