NDI 3 years in OB havent used sdi for a long time

These videos have really great production quality and your forum looks great too. Good work! Its amazing to see how far the linux desktop experience has come. The only rub right now is latency for realtime playback. Its fine when running linux native reaper but I have some windows only plugins from Neural. I actually tried the tactic of running Reaper itself in wine since Neural uses the awful iLok DRM. The latency was just bad enough to sound like a really really shallow reverb.

I just got this card for my home media server. All my files are in h.264 so I almost never transcode, but the few times I do, it nearly pegged my CPU at 100%. It’s a 2008 Intel Xeon E5450 @3.0 GHz, 8GB of DDR2-800 memory, an Intel 120GB SSD, 3TB and 8TB storage drives to run PLEX on Ubuntu Server. Yes, I did the LGA-771 mod. I had to update my Kernel and install Mesa like you said, but it works. Transcodes happen on the card and the CPU stays at IDLE! Great little card for video transcoding and keeping power usage on such an old system down. I used console only version of Ubuntu and it runs at about 350MB of memory usage idle. The SSD keeps the whole thing snappy and gives a good spot for transcoding to operate from while the slower drives are more than capable of keeping up with my needs. The 3TB I use as a share drive on my network and the 8TB is solely for media storage for Plex. I haven’t even hit 3Tb used on it yet, though.

Saw this video and literally bought 2 on ebay. Thanks!

How much more powerful is the A310 compared to a typical Xe iGPU for ML? Planning to put it into my NAS for encoding and some ML

Have you tried Benylin?

After this instruction my OBS won't start, I did something wrong somewhere. Otherwise, I don't know anything about Linux, I tried this on LinuxCNC.

There's also DroidCam, but the android app isn't open source. However, the advantage is that it works over USB too (or wifi, if you prefer)

I've been using NDI & OBS but on Windows, when I loaded OBS on Linux on the same computer, OBS complained about the video adapter beeing no good, so I tossed Linux and went back to Linux. At Church we have two PC's one for slides (PowerPoint) the other for cameras and streaming via OBS. We use NDI to ger video of the slide show to superimpose ovee the video stream as needed.

Amazing intro. Amazing video. Amazing voice. You could voice Solid Snake if you wanted. Great job!!

When two computers are involved anyway, those HDMI->USB video capture cards (as shown in last minute) are cheap and work without any proprietary software. Of course for single stream capture, those fancy multi-stream stuff remains exclusive to NDI.

This is cool in theory until you introduce legacy consoles and HDMI devices that don't support it into the mix. Like the Xbox One or Xbox 360 or OG Xbox or Nintendo Wii with HDMI adapters or Nintendo GameCube with HDMI adapter or Nintendo Wii U or Nintendo Switch or Sony PlayStation 3 or above. Simply, if you're going to be recording consoles, or any other device, a capture card is a guaranteed, best bet. However, if you're going to just be recording computers, a computer, this is better.

The reason I would use a capture card is to not put strain on my PC

Do you know if this will compile on ARM? Would like to try it on my Radxa Rock 5B maybe.

I had no idea they had NDI tools for Linux

"Ethernoodle" Thanks for ruining my vocabulary. :')

i recently got some motivation to make music with a friend again hes down this is great news

Thanks man for making this video, have been looking for ages...Easy to understand and even i got it to work :D Much Appreciated. Keep up the good work!

(EDITED) Commented on the wrong video, lol :P

is this NDI6 in general or HX? normal NDI used to be 100mb for a 1080i59.94 signal

too bad it's closed source.

I volunteer for a church and we're working on upgrading from a handicam and an HDMI capture card to something a bit... less janky. They ultimately chose SDI6G as the interface, but the demo I did used NDI and it was crispy :)

NDI basically means... you're not gonna notice the difference...

The bandwidth part is for NDI HX and on OBS, for some reason, does not allow you to change the bitrate. Some ndi sources can eat up to 150Mbps at 1060@60, because they follow the "full" spec.

Just need to find some POE SBC’s with hdmi out to act as NDI receivers for TVs, could save some $$$ vs paying $200+ for HDbaseT stuff

Glad to see NDI still works well

if you're just going between obs instances you might as well just use teleport, it's way less hassle

whoa i never heard abt this. seems super useful for gettig video off modded consoles if someone makes an application for this. like ik the video would be trash off something like a 3ds but this would allow for this to work. and for a switch this is an alternative to usb capture that requires the console to be in handheld mode

why do linux users tend to treat it as a "secret thing" been on linux for years, it feels weird at first, but when 95% is browser based anyways, it makes no difference. also windows sucks hard.

sorry for the unrelated question, I know it's in the bingo card, but is there an easy link to the music used in the video ? I quite like it

Great stuff as always. Thanks Venn!

I used to use something called teleporter for obs not sure if still supported did about the same thing. Still cool

3:40 This is not megabits per second, It's megabytes per second. So you can carry about three 4k streams before the typical gigabit ethernet starts to sweat. Fast ethernet is hopeless even for full HD.

That is a really cool technology that I didn't know existed but wanted to try for quite some time

In the NDI bandwidth requirements section you say "megabits", but the sysinfo is displaying "mebibytes". 30 megabits is ~3.8MB/s. But 30 mebibytes is 31.45MB. This might cause confusion.

I bought one if these a310's.. and now I've ordered an adaptor cable so I can plug its fan into a 4pin mobo fan header and control it myself. will reply here how well that works when it arrives.

The installation is a bit roundabout but consider giving NDI a look. It's a cheap way to expand your current setup.

I hope it's okay to ask as a linux nooB: I had a gen 1 8i6. I saw there were no linux drivers for the GUI for it, and I want to use it with Reaper. So I went and bought a gen4 2i2. I tried following what directions I could find (I'm on Nobara, which I understand is related to Fedora) and ran into a problem where a popup says it needs a firmware update to work. I went to the link that popup provided and saw some files I am unfamiliar with how to run, such as .deb and tar.gz. I read somewhere else to place a file in a folder as usr/lib/firmware/scarlett2, but no such folder exists on my setup even though I tried installing the main linux/scarlett2 a couple of different ways. I followed the github install directions as best I could understand, typing in various commands but still ran into the same popup/warning. I can't find any more clear instructions on what to do at this point, and the scarlett2 folder still doesn't exist where it is supposed to. Thanks to anyone for any possible help. I really want to get linux working to get away from windows if possible.

friend, I don't know if it's some ardour bang, although all the procedures were completed successfully, on mine the cursor isn't stopping, I usually press the home key to go back to the beginning and it starts on its own, even with the mouse it does this, could anyone to help?

this thing is a BEAST it's cheap and fast, got one for a mini NAS Project

I'm going to try this out. For the money, I think the AVerMedia BU113 Live Streamer Cap 4K is a WAY better deal and you don't have to buy it USED. Goes for $80-$100 new. The AVermedia capture card also supports up 4k resolution and uses USB C instead of USB A. This Magewell maxes out at 2048x2160p? What the hell kind of resultion is that? I don't think they advertise it but, the AVerMedia is Linux compatible. Mine works with Fedora, Mac and PC. Yes, the software is only available for windows but, I haven't needed any software to get it to capture my camera's HDMI in OBS on Windows, Linux or Mac. They do provide a list of compatible cameras and even my unlisted Canon works. Only little idiosyncracy on in OBS on Linux is when you try and select a resultion 4k isn't listed but, it still captures if you set it to default. It will let you select 4k in windows. Case is plastic and I've def stepped on mine but didn't hear it crack so we're looking good.

Those are great news. I've been using Linux Mint 22 (since the Beta) using pipewire/FFADO and jack (not emulation) by installing Ubuntu Studio Audio configuration from the Mint Repo. It works just fine. Both Ubuntu Studio and Linux Mint 22 work fine with FFADO and Pipewire. Latency is better than pulse audio but not that of a huge but at least is working. For those who love mint and ubuntu. It is a great flavor to add. A hello from Brasil. P.S. I tried to do all these steps you showed with Debian and did not work.

🤣 Poor LTT Linus

cool 👍

Open Source FTW, and Pipewire is looking better and better! Kudos for this channel, this is GREAT content.

This was an interesting experiment. It's good to know the FFADO drivers will be alive and kicking for future generations. 00:00 Intro 00:11 PipeWire / FFADO history 01:08 Setup 01:21 Check PipeWire version 01:31 Install packages 01:44 Configure rtprio, niceness, and memlock 01:53 Add user to pipewire group 01:58 Disable ALSA drivers 02:18 Configure PipeWire FFADO module 02:36 Testing 02:39 Round-trip latency 02:56 Desktop audio 03:17 Digital audio workstations 03:32 Verdict
