[Live-devel] Live555 Buffer Latency

Hello,

My name is Jon Anderson. I am working on an application using Live555 to stream L16 data for real-time audio playback at the lowest latency possible. I have stripped down many buffers on the OS side and have gotten my stream to playback with a latency of about 60 - 70 ms. My attention is now focused on Live555. I have notice several buffers built into Live555, but the only one that I am expecting to cause latency is the ReorderingPacketBuffer. For now, my plan is to get the latency down to as low as possible and then work it up for the sake of audio quality. With that in mind, I set the ReoderingPacketBuffer threshold time to 0ms. What other buffers might be causing audio playback delay?
