Therefore, you are going to lose data. End of story. Note that - in this case - RTP-over-TCP streaming will not save you. If you try to stream over a too-low-bandwidth network using TCP, you'll still get data loss, but it'll occur at the sender (because of its OS buffer overflowing), rather than at the receiver.<div><br></div><div>This is the important distinction between live media streaming, and on-demand streaming (e.g., using the World-Wide Web). If you use our software, it's important to understand this distinction.</div><br><br><div apple-content-edited="true">
