# What is it?
In this repository collected different pipelines with workarounds for zero latency streaming.
Main idea for now is using of docker container with running Ubuntu 22.04 distro inside, mostly for testing purposes.
We must passthrough in this case GPU and Decklink devices for this purpose it is necessary to have similar driver versions on host and container system, otherwise it just will not work.
Component diagram showing what we want to achieve
```plantuml
``@startuml
node "Host" {
package "Docker" {
interface "UDP socket" as USock
package "Container" {
USock - [Gst Pipeline]
}
}
USock ..> NetworkBridge
[Kernel] -left- GPU
DeckLink -up- [Kernel]
NetworkBridge - [Docker]
NetworkAdapter -left- [Kernel]
[Gst Pipeline] ..> GPU
[Gst Pipeline] ..> DeckLink
NetworkBridge ..> NetworkAdapter
}
node "Router" {
port PhysicalPort1
port PhysicalPort2
NetworkAdapter --> PhysicalPort2
}
node "Oculus" {
interface WiFi
component MedicineApp
MedicineApp <-- WiFi
WiFi --> PhysicalPort1
