Functions

func Keyframe

func Keyframe(codec string, packet *rtp.Packet) (bool, bool)

Keyframe determines if packet is the start of a keyframe. It returns (true, true) if that is the case, (false, true) if that is definitely not the case, and (false, false) if the information cannot be determined.

func KeyframeDimensions

func KeyframeDimensions(codec string, packet *rtp.Packet) (uint32, uint32)

func RewritePacket

func RewritePacket(codec string, data []byte, setMarker bool, seqno uint16, delta uint16) error
