◆ HasAvailablePacket()
| bool PacketBuffer::HasAvailablePacket | ( | void | ) | const |
Returns true if there are ordered packets ready for processing.

◆ PopDataPacket()
| UDPPacket PacketBuffer::PopDataPacket | ( | void | ) |
Fetches a data packet for processing.
Call FreePacket() when done with the packet.

◆ GetEmptyPacket()
| UDPPacket PacketBuffer::GetEmptyPacket | ( | void | ) |
Gets a packet for use in PushDataPacket/PushFECPacket.

◆ FreePacket()
| void PacketBuffer::FreePacket | ( | const UDPPacket & | packet | ) |
Frees an RTPDataPacket returned by PopDataPacket.
- Note
- Since we return UDPPackets and not pointers to packets we don't leak if this isn't called, but by preventing the reference count on the QByteArrays from going to 0 we can reuse the byte array and avoid mallocs.
