Re: [Ccrtp-devel] Packet Size - HELP

   Ummm, the change

   means that you will read 65534, but only the first 8192 (returned
by getNextDataPacketSize) are actual payload received in an RTP
packet. If you use IPv4, you won't be able to send more than 64k bytes
in a packet, and in principle ccRTP is able to send/receive packets
that long. That's a huge packet size for a normal RTP application
anyway. What codec are you using?
