SVT-AV1 for real time transmission

[Habor]

Hi,
I have following Client-Server Situation:

Server:

• maintains multiple CEF (Chromium Embedded Framework) frames (like a background webbrowser)
• those CEF frames deliver image data in irregular intervals - varying between 0-30fps
  if a video is played or a lot user interaction is going on it's 30fps - very rarely(!)
  usually no image data is delivered if nothing is happening - most of the time
• sending this data to the client as is puts too much weight on the network connection
• thus I use or would like to use SVT-AV1 encoding

Client:

• receives SVT-AV1 data, decodes and presents it (yes, SVT-AV1 contains a decoder)
• user interaction (mouse, keyboard) is transmitted to server CEF frames via another connection

Problems

1. SVT-AV1 seems to require a steady(!) stream of input frames.
2. It also seems to spit out encoded frames (packages) after long time intervals but I can only wait a few milliseconds or the lag makes it unusable.

Questions

1. Can anyone tell me how I have to tweak those SVT-AV1 encoder parameters so I reliably get an encoded packet after inserting new frame image data? (1 for 1)
   Packets do not need to be/contain keyframes (except the first one of course).
2. Can anyone tell me how I have to tweak those SVT-AV1 decoder parameters so I reliably get a decoded frame after inserting a packet (1 for 1)
3. Otherwise where/whom could I ask those questions?

Notes

• I use the SVT-AV1 library, not the executable.
