SysDVR
Stream/record gameplay to a PC via USB or network.

​

Update: Version 5.0 has been released with low latency streaming, be sure to check it out on github.

This is an experimental sysmodule that allows capturing the running game output on a pc.
As this uses switch's built-in game recording feature it has the same limitations: [email protected] and only works on the games that enable it, but by sending the video to another device there's no time limit to the recording.

There are two modes: USB and Network, both work fine but USB is slightly better, at least compared to wifi, didn't try with a LAN adapter.
Players like mpv or vlc can play the stream directly so you can use any screen recording applications but it's also possible to write the stream directly to a file.
To use the USB version you need the UsbStream program you'll find on the github page, it's built using .NET 5 and works on both windows and linux, haven't tried mac but in theory it should work too.

You can see it in action in the two teasers i posted while working on it:

As you can see it's not meant for remote play, but it can work as a basic capture card, audio output is uncompressed so it can be useful for ripping OSTs .

Is there anything like this but with controller support? I want to use my controller that's on PC on Switch, so I don't have to switch (pun) back and forth.

So, with this sysmodule isn't possible to stream Smash right?
Any alternatives?

For now only a capturecard.

After like one year I finally downloaded this and I got it to work. Nice that it has a builtin player. If I’m correct all I have to do is just download a screen recorder. Unless this is actually recording my gameplay somewhere on my computer. I can’t believe it took me like a year just to try this out. On the bright side I guess, there’s a lot less bugs from the first version of SysDVR.

I haven't used this since release but I'm gonna set it back up, thanks for your hard work!

Yeah its actually very good. Just the patches for being able to record on any game is worth enough.

Anyone got the latest 5.3 working on both latest Atmosphere/Horizon?
It crash my switch with an Atmosphere fatal error code as soon the emunand is loaded.
5.2 was working fine.

For me it works without any problem, my default setting is off, and I only enable streaming when I use it with my sysDVR-Overlay.
Do you have any other system modules installed? Sometimes they can interfere in weird ways, when there are to many, or when some of them are not fully compatible.
You could also try to just delete the config on your sd-card.

And it should have finally been fixed in latest release

is it possible to configure size of buffer manually? i tried 30fps lock and 10mbps bitrate on atmosphere config and holy it's stable... if picture is not static.

No ,currently it's a constant in the code both for the sysmodule and for the expected max size in the client.

So anyone using this in combination with dvr patches for Smash? Does it cause crashes or oddities?

 

[Akumara]

I think this broke in the latest update.

 

[reirahul]

Got it working

Probably dumb question: Is this safe to use this while playing an online game?

SysDVR itself should be perfectly safe. As long as you have no NSPs installed, aren't using an unofficial custom avatar, aren't using cheats in the game etc, you should be good.

Two question here. I started using sysdvr on my switch lite with picofly today. Its possible to mute sound om switch when i stream games from switch over usb? For now i use wire headphones but i dont have them always.
Is my switch charging over USB when i use sysdvr on my Dell Latitude Laptop?
