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: 720p@30fps 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 .

wireless works, but i'm trying wired for the first time and i'm getting this error
Unhandled exception. LibUsbDotNet.LibUsb.UsbException: Entity not found
at LibUsbDotNet.LibUsb.ErrorExtensions.ThrowOnError(Error error)

EDIT: updated the 2 drivers with zadig and it works now

4.0.1 doesnt work on lite, 5.0 work and more simple than before

Recently started using this.
Usecase: Stream to my Coreelec-box, thus being able to use hyperion with my switch. Latency is great with cache disabled.
Just to be clear. I dont play watching the stream - it`s "only" used to generate ambilight while the TV uses the switch as source.
works fantastic! Thank you!

Hello, this is absolutely fantastic! Really easy to setup, I had it running in about 10 minutes, streaming via usb it looks great with little to no latency even with both channels enabled, amazing work!
I just have a little question. I have noticed that some games stream with a watermark at the bottom of the screen, not a big deal but for example in Hyrule Warriors AoC the text is so large it covers part of the UI, is there a way to remove it through modding or some other method?

 

[NEVERxTHAT]

Hi any help would be amazing. I've got sxos on latest firm, downloaded and put the sysdvr on as suggested changing atmosphere folder to Sxos, goto sysdvr settings and get stuck on this screen. I've restarted the switch also.

Thanks guys/girls

someone should make a 3d printed dock for an rasberry pie setup wich fits an switch lite :>

Is USB streaming for long sessions let's say 1 or 1 and a half hours safe? I tried a little and works fine but you know,the switch is delicate with that part on specific

Software-wise I don't see how it could cause any damage. Hardware-wise, as long as you're not yanking the console/cable around I don't see how it could be a problem, I've played hundreds of hours handheld with the charging cable plugged into that socket and it's fine.

Could an option to record on the Switch itself be added? Like how the other consoles do. Or could be added an option to connect to Android like the Switch being detected as a UVC Camera or via WiFi too but on Android. For those without PC or Laptop.

 

[hotsuma2002]

Hello, did someone try USB streaming with SysDVR & it prompts the "Warning: winusb error Timeout while requesting data"?
May I know how to fix it?
My device is a switch lite with sxos. I tried to re-install the WINUSB driver many times. It only works if I checked "Force Libusb backend", but the graphics are choppy & laggy.
Thanks a lot!

Currently i'm not planning recording on the console itself, at some point i may work on android client but it's not a priority. You can stream to android using the simple RTSP mode and a player like vlc or mpv but quality heavily depends on the connection strength.

I don't know, maybe you connected switch to an usb hub and that slows everything down ? or it could be a bad usb wire. Now that i think of it there's this issue which can affect usb performances but it seems to only affect people on linux, you may want to try the workaround provided in the thread but idk if it will help you.

Hi Exelix11,
Thanks for your reply. Your SysDVR is really awesome.
I found out it is not my PC/laptop/switch lite problem. That is because SysDVR cannot stream all the games smoothly neither with the default player or MPV. I tried with usb mode & bridge mode. The result are same. Some games may be choppy or full of noise on the screen. E.g. Curse of the Moon 2, labyrinth of refrain.
others were fine like Mario, Zelda, Katana Zero, ...

Hopefully it will be fixed later. Thanks a lot.

I know, it happens on 2d games or scenes with a mostly static screen, it's being tracked here: https://github.com/exelix11/SysDVR/issues/91 currently there's no fix but i'm looking into it.

And it should have finally been fixed in latest release

I have the same problem. Did you manage to solve it? If so, what did you do?

 

[Juicex3]

anybody knows how to make the best upscaling for 1080p.

I mean if I recorded it and after that.
i tried online converter tools but the quality is not good.

can i make the quality better when i use a Nvidia GPU ?

Hi dear exelix11, I guess there is still no support for OFW 12.0.0 / AMS 0.19.1?..

There's no need for an update, version 5.1 works fine on latest firmware and atmosphere versions.
