type BitArray struct {
	// contains filtered or unexported fields
}

BitArray provides support for bitmask manipulations.

func NewBitArray(sizeBits uint32) BitArray

NewBitArray returns a new BitArray. It takes sizeBits as parameter which represents the size of the underlying bitmask.

func (b *BitArray) GetBit(bitIndex uint32) uint8

GetBit returns the bit value at a specified index of the bitmask.

func (b *BitArray) GetBitValue(i int, j int) uint64

GetBitValue returns a subsection of the bitmask.

func (b *BitArray) Marshal() []byte

Marshal returns the underlying bitmask.

func (b *BitArray) SetBit(bitIndex uint32, bitValue uint32)

SetBit sets a bit to the specified bit value on the bitmask.

type MediaPacketIterator struct {
	// contains filtered or unexported fields
}

MediaPacketIterator supports iterating through a list of media packets protected by a specific Fec packet.

func NewMediaPacketIterator(mediaPackets []rtp.Packet, coveredIndices []uint32) *MediaPacketIterator

NewMediaPacketIterator returns a new MediaPacketIterator.

func (m *MediaPacketIterator) First() *rtp.Packet

First returns the first media packet to iterate through.

func (m *MediaPacketIterator) HasNext() bool

HasNext indicates whether or not there are more media packets that can be iterated through.

func (m *MediaPacketIterator) Next() *rtp.Packet

Next returns the next media packet to iterate through.

func (m *MediaPacketIterator) Reset() *MediaPacketIterator

Reset sets the starting iterating index back to 0.
