Feature: v1_16

Additional RTP buffer flags. These flags can potentially be used on any buffers carrying RTP packets.

Note that these are only valid for gst::Caps of type: application/x-rtp (x-rtcp). They can conflict with other extended buffer flags.

The gst::Buffer was once wrapped in a retransmitted packet as specified by RFC 4588.

The packet represents redundant RTP packet. The flag is used in gstrtpstorage to be able to hold the packetback and use it only for recovery from packet loss. Since: 1.14

Offset to define more flags.

Feature: v1_10

Additional mapping flags for RTPBuffer::map.

Skip mapping and validation of RTP padding and RTP pad count when present. Useful for buffers where the padding may be encrypted.

Standard predefined fixed payload types.
