| const GstRTPPayloadInfo * | gst_rtp_payload_info_for_pt () | 
The GstRTPPayloads helper functions makes it easy to deal with static and dynamic payloads. Its main purpose is to retrieve properties such as the default clock-rate and get session bandwidth information.
#define GST_RTP_PAYLOAD_IS_DYNAMIC(pt) ((pt) >= 96 && (pt) <= 127)
Check if pt
 is a dynamic payload type.
const GstRTPPayloadInfo * gst_rtp_payload_info_for_name (const gchar *media,const gchar *encoding_name);
Get the GstRTPPayloadInfo for media
 and encoding_name
. This function is
mostly used to get the default clock-rate and bandwidth for dynamic payload
types specified with media
 and encoding
 name.
The search for encoding_name
 will be performed in a case insensitve way.
const GstRTPPayloadInfo *
gst_rtp_payload_info_for_pt (guint8 payload_type);
Get the GstRTPPayloadInfo for payload_type
. This function is
mostly used to get the default clock-rate and bandwidth for static payload
types specified with payload_type
.
Standard predefined fixed payload types.
