Are there any existing plug-ins for virtual microphone? I want to use OBS'S realtime noise suppression and noise gating in another app (mainly online lecture platform Echo360). I got it working using VoiceMeeter in what seems like a hacky way, but only with high latency so far.

I think there should be software that provides virtual audio devices, so you could configure it as the output for OBS and the input for you other application - something like this: https://www.vb-audio.com/Cable/

Yes, that's what VoiceMeeter does (same author).

I randomly learned OBS a while ago for doing some twitch streams in the evenings. I'm so glad I did. I run a 6,000 people company during the day and have OBS setup to push into Google Meet. I've done townhall with live on-screen Q/A voting, hosted podcast discussions, done PIP product reviews. I use its video record feature to react to figma prototypes and post the MP4s in the respective channel for discussion. OBS i…

On Mac I use Soundflower to redirect audio between apps.

There'a also AULab which can be used for some effects in realtime (e.g. adding reverb and redirecting to built-in audio out).

Can you recommend any resources for learning OBS? My daughter wanted to record some videos of her playing a web-based game. I found the interface to OBS unintuitive. I managed to figure out how to capture a specific area on the desktop, but it was unexpectedly difficult to resize the output to match the input. I found some way of doing it that I can't remember. A few months later I had to do it again and that time I…

Osiris, there are a lot of tutorials around learning OBS. One of the best ones that I've come across is EposVox's OBS Studo Master Class 2018. It helps you figure out what you want to learn and covers a large swath of the various OBS functionalities.

I'm aware of wlroots. But KDE, GNOME, Enlightenment, etc. don't use it, so each of those have to implement things separately. Concerning the desktop portal API. It's basically just a wrapper around the native custom API's of the underlying compositor. And it is pretty limited in functionality. For example, the screenshot API just has a way to request a screenshot, it doesn't have a way to specify that you would like…

I'm actually more concerned about the fact that wlroots has/had to duplicate work done by Gnome and KDE (wlroots is more recent than much of gnome and kde's wayland support).

> Yes, that's on purpose. What's supposed to happen is that the portal daemon (NOT the application) pops up a dialog asking the user to choose which one they want. Unfortunately the wlr portal is still not done yet and doesn't implement this.

Yeah, the problem is that each compositor has to implement it's own screenshot dialog, and you _have_ to go through that dialog for that compositor. So on wlroots, currently, an app can only get a full screen screenshot. And a tool like flameshot becomes awkward if the compositor opens it's own dialog. In X, if you don't like Gnome's screenshto tool, you have a handful of other options. With wayland, tough luck, the most you can get is a better editor/annotation tool.

> with per-compositor "solutions" Didn't every one agree to use Pipewire for that? Or it's still bikeshedded to death? Somehow for input, everyone settled on libinput and this didn't become a problem.

That's mostly the case now, but that's a much more recent development than Wayland on the desktop becoming popular. Also, pipedrive gives you the plumbing, but you still need the portal API. My understanding is everyone more or less agrees that's the way forward, but it's still not stable and ubiquitously implemented. Even then, that resolves capture but not control: if you want something closer to ssh -X you need wa…

May be libinput should also implement remote features?

If you're running a modern Linux desktop you're probably running Wayland, and screencasts on that have long since been a complete pain in the neck with per-compositor "solutions" that mostly don't work quite right. Fortunately someone who works on Gnome wrote the obs-xdg-portal plugin that should fix this, at least for Gnome and hopefully soon for wlroots and KDE once they fully support the underlying portal API. Unt…

Does Wayland do anything better than Xorg? Every time I see it mentioned, it is about how it does not support this or that core feature of Xorg (e.g multiple displays with custom pixel densities/scaling, screen sharing apps being broken, etc...). What is Wayland's reason for existing?

I had to turn on X11 for screen recording once (the screen recording was done by a windows only app running under wine). It didn't take a minute to see extreme tearing. I seriously don't understand how anyone can use X11 other than as a fallback.

I'm kinda new to Linux as a desktop, and thus went straight to Wayland, so these kinds of comments from ol'-timers are super interesting to me. I run a Wayland desktop, and I start it by typing it's executable from the TTY after I log in. No fuss, no muss. Everything works great, except there was this one game I wanted to try out that's a Windows .exe and needs to run in Wine and I couldn't quite get it to run in Way…

The screen tearing isn't caused by X. It's a faulty video driver.

You had decades to fix the faulty video drivers for X11.... Meanwhile they work on Wayland since day one.

Love OBS.

I have a Sony A6000 going into it via a Elgato HD60 S. A Rode NT-USB microphone and a green screen my brother made me (big, solid, wooden... it's awesome.)

OBS has enabled me to create super high quality training videos and also provide excellent remote working video conferencing capabilities. I can basically do remote pair programming with this thing... it's amazing.

I've been using OBS for a couple months for live streams on YouTube (see https://www.jeffgeerling.com/blog/2020/ansible-101-jeff-geer... ), and I have had rock-solid reliability, using an external mic interface, an external camera (displayed PIP), and sharing one of two displays during some instructional sessions. One thing to keep in mind, though—unless you have a dedicated video card, and it's supported by OBS (the…

Thanks for all of your contributions to the ansible ecosystem! My team and I greatly appreciate the work you do.

I love OBS, just started using it a couple weeks ago. I am using the v4l2loopback plugin on Linux to output the video to Zoom. Is there a way for it to output the sound similarly to be used as an input in Zoom for Linux? I'm using a blackmagic decklink mini recorder as input, and Zoom won't accept it as a mic, but OBS does. I've tried a bunch of hacks with pavucontrol, but nothing will let me accept the OBS output as an input into Zoom. Does anyone have any ideas?
