~1s steaming latency on V3+VLC #22

Hey there, thank you for this wonderful work!

While testing this out with VLC, it appears to have about 1s latency from camera to VLC.

Do you happen to know the cause of this? The IMP_Encoder_GetStream -> crb_tcp_hook path seems reasonable to me and I don't see any buffers there (and it seems to run off the encoder thread?). I am suspicious that this is VLC buffering things too aggressively, as the app-based streaming seems faster.

Yeah it's all in VLC.

As you observed, there's no buffering in the server code. I don't know about buffering in or before IMP_Encoder_GetStream though. You might try other players and see if it's better or worse than VLC.
