# kaukosohva

Play games remotely with Linux.

## Current state 

This is proof of concept prototype for technical users. 

# Architecture

![Architecture](https://github.com/raspi/kaukosohva/blob/master/doc/Architecture.png)

# Main problems TODO

* Lower the latency for streaming

  * Minimize streaming buffer(s)

  * Tune h264 parameters for lowest latency

  * Tune RTP parameters for lowest latency

  * Constant or variable bitrate (CBR or VBR)?

# FAQ

* Why h264?

  * Because GPU encoding/decoding hardware acceleration

* Why h264 over RTP?

  * Because it's a standard - https://tools.ietf.org/html/rfc6184

* Why multicast?

  * Eliminates need for extra server software as kernel sends host's stream to everyone connected to the VPN automatically

* Why GStreamer?

  * Lots of tuning options

  * Lots of plugins

  * Debugger - https://gstreamer.freedesktop.org/documentation/tutorials/basic/debugging-tools.html

  * View latency issues in the pipeline - https://www.flathub.org/apps/details/org.freedesktop.GstDebugViewer

* Does it matter who hosts VPN (WireGuard)?

  * Who has the most bandwidth and stable connection is recommended

  

# See 

* [host](host) directory for how to host a game

* [remote-player](remote-player) directory for how to connect to a host as a remote player

# Not tested yet

If h264 over RTP multicast doesn't pan out there's still many things to try with GStreamer:

* Drop multicast and stream to UDP port in a remote player's machine (this limits player count)

* Try h264 inside [MPEG-TS](https://gstreamer.freedesktop.org/documentation/rtp/rtpmp2tpay.html?gi-language=c) container over multicast

* Try GStreamer's [RTSP server](https://github.com/GStreamer/gst-rtsp-server) if the host doesn't have enough upload bandwidth for all players there's RTSP proxies like [rtsp-simple-server](https://github.com/aler9/rtsp-simple-server)

* [RTMP](https://gstreamer.freedesktop.org/documentation/rtmp/index.html?gi-language=c)

* [SRT](https://gstreamer.freedesktop.org/documentation/srt/index.html?gi-language=c)

* and others

# Tested, didn't work

* ffmpeg, mpv, vlc 

  * too many buffers

  * 1000-4000 ms+ latency even locally
