Types ¶
type H264Packet ¶
type H264Packet struct { IsAVC bool // contains filtered or unexported fields }
H264Packet represents the H264 header that is stored in the payload of an RTP Packet
func (*H264Packet) IsDetectedFinalPacketInSequence ¶
func (p *H264Packet) IsDetectedFinalPacketInSequence(rtpPacketMarketBit bool) bool
IsDetectedFinalPacketInSequence returns true of the packet passed in has the marker bit set indicated the end of a packet sequence
type H264PartitionHeadChecker ¶
type H264PartitionHeadChecker struct{}
H264PartitionHeadChecker checks H264 partition head
func (*H264PartitionHeadChecker) IsPartitionHead ¶
func (*H264PartitionHeadChecker) IsPartitionHead(packet []byte) bool
IsPartitionHead checks if this is the head of a packetized nalu stream.
type OpusPacket ¶
type OpusPacket struct {
Payload []byte
}
OpusPacket represents the Opus header that is stored in the payload of an RTP Packet
func (*OpusPacket) IsDetectedFinalPacketInSequence ¶
func (p *OpusPacket) IsDetectedFinalPacketInSequence(rtpPacketMarketBit bool) bool
IsDetectedFinalPacketInSequence returns true as all opus packets are always final in a sequence
type OpusPartitionHeadChecker ¶
type OpusPartitionHeadChecker struct{}
OpusPartitionHeadChecker checks Opus partition head
func (*OpusPartitionHeadChecker) IsPartitionHead ¶
func (*OpusPartitionHeadChecker) IsPartitionHead(packet []byte) bool
IsPartitionHead checks whether if this is a head of the Opus partition
type VP8Packet ¶
type VP8Packet struct { // Required Header X uint8 /* extended control bits present */ N uint8 /* when set to 1 this frame can be discarded */ S uint8 /* start of VP8 partition */ PID uint8 /* partition index */ // Extended control bits I uint8 /* 1 if PictureID is present */ L uint8 /* 1 if TL0PICIDX is present */ T uint8 /* 1 if TID is present */ K uint8 /* 1 if KEYIDX is present */ // Optional extension PictureID uint16 /* 8 or 16 bits, picture ID */ TL0PICIDX uint8 /* 8 bits temporal level zero index */ TID uint8 /* 2 bits temporal layer index */ Y uint8 /* 1 bit layer sync bit */ KEYIDX uint8 /* 5 bits temporal key frame index */ Payload []byte }
VP8Packet represents the VP8 header that is stored in the payload of an RTP Packet
func (*VP8Packet) IsDetectedFinalPacketInSequence ¶
IsDetectedFinalPacketInSequence returns true of the packet passed in has the marker bit set indicated the end of a packet sequence
type VP8PartitionHeadChecker ¶
type VP8PartitionHeadChecker struct{}
VP8PartitionHeadChecker checks VP8 partition head
func (*VP8PartitionHeadChecker) IsPartitionHead ¶
func (*VP8PartitionHeadChecker) IsPartitionHead(packet []byte) bool
IsPartitionHead checks whether if this is a head of the VP8 partition
type VP8Payloader ¶
type VP8Payloader struct { EnablePictureID bool // contains filtered or unexported fields }
VP8Payloader payloads VP8 packets
type VP9Packet ¶
type VP9Packet struct { // Required header I bool // PictureID is present P bool // Inter-picture predicted frame L bool // Layer indices is present F bool // Flexible mode B bool // Start of a frame E bool // End of a frame V bool // Scalability structure (SS) data present // Recommended headers PictureID uint16 // 7 or 16 bits, picture ID // Conditionally recommended headers TID uint8 // Temporal layer ID U bool // Switching up point SID uint8 // Spatial layer ID D bool // Inter-layer dependency used // Conditionally required headers PDiff []uint8 // Reference index (F=1) TL0PICIDX uint8 // Temporal layer zero index (F=0) // Scalability structure headers NS uint8 // N_S + 1 indicates the number of spatial layers present in the VP9 stream Y bool // Each spatial layer's frame resolution present G bool // PG description present flag. NG uint8 // N_G indicates the number of pictures in a Picture Group (PG) Width []uint16 Height []uint16 PGTID []uint8 // Temporal layer ID of pictures in a Picture Group PGU []bool // Switching up point of pictures in a Picture Group PGPDiff [][]uint8 // Reference indecies of pictures in a Picture Group Payload []byte }
VP9Packet represents the VP9 header that is stored in the payload of an RTP Packet
func (*VP9Packet) IsDetectedFinalPacketInSequence ¶
IsDetectedFinalPacketInSequence returns true of the packet passed in has the marker bit set indicated the end of a packet sequence
type VP9PartitionHeadChecker ¶
