Hi Everybody. 
I'm trying to get a better understanding of how the Video encoding latency gets down to 15ms with Doodle Labs integration? I recognize these are two separate statements that are in the same paragraph so it may not be possible. 
Has there been any improvements to Doodle Labs Mini OEM getting a lower latency below 100ms? I'd love to test this out myself.

@Demarconius Yes, we can achieve ~50ms glass to glass using our VRX and voxl-vtx software service on the UAS-side.

@Moderator

Thanks for the clarification on the ~50 ms glass-to-glass number.

Trying to get a better understanding  the performance envelope:
	1.	Does the 50 ms include RF transport over Doodle, decode, and HDMI output latency, or is that measured only within the VOXL + VRX software stack?
	2.	Was this measured in point-to-point mode or mesh routing mode?
	3.	Can you expand on  bitrate, resolution, and encoder settings were used (GOP structure, B-frames disabled, UDP vs RTSP)?
	4.	Is MAVLink or other traffic running on the same link during that measurement?
	5.	Do you have a latency breakdown per stage (encode / RF / decode / display)?

Appreciate any information you can provide. I just want to make sure I can test and validate this effectively.
