Dynamically Adaptive Video using RTP/RTCP

[arnav dhamija]

Hi

I am working on an application which requires video streaming from a 
V4L2 webcam on a drone to a laptop. In this project, I need the H.264 
encoded video to adaptively modify its bitrate according to the 
available bandwidth of the WiFi link between the drone and the laptop. 
The sender in this case is a computer mounted on the drone, and the 
receiver is the laptop.

I plan on using RTCP packets for relaying the QoS information from the 
laptop to the drone. However, I am not sure how to change the encoder's 
settings during streaming based on the QoS report. Is using Dynamically 
Controllable Parameters 
(https://gstreamer.freedesktop.org/documentation/application-development/advanced/dparams.html) 
the way to implement this?

I have also gone through the QoS tutorial documentation 
(https://gstreamer.freedesktop.org/documentation/plugin-development/advanced/qos.html). 
Since this doesn't discuss receiving QoS information the receiver, is 
this only for measuring the intra-pipeline QoS due to bottlenecks in the 
pipeline?

Lastly, how can I configure GstRTSPServer to accept and process RTCP 
packets?

Thanks!
