Obs problems on Ubuntu

[vertifor922]

Here's what the terminal returns before and after connecting the camera, I think I've located the camera and indicated it with a white arrow.
Below everything that is returned by the LIBGL_ALWAYS_SOFTWARE=1 obs command that I use to start Obs

[AaronD]

That Vendor ID (VID) comes up as several different kinds of toy cameras, but that Product ID (PID) isn't listed.

http://www.linux-usb.org/usb.ids

USB ID Database

Database of USB devices and their Vendor and Product ID's

the-sz.com

That's not too concerning though, as a vendor is only assigned a VID, and they can do what they want with the PID.

But because the PID's that do exist are listed as toys, what do you *actually* have? Was the seller or manufacturer dishonest? It's not a brand that I recognize, either from your original Amazon link or the USB report.

Given that, it's entirely possible that that camera just doesn't do audio over USB. The Advanced Linux Sound Architecture (ALSA) doesn't see it, so OBS almost certainly won't.

It might be interesting to see the result of lsusb -d 0979:0278 -v. (while it's plugged in of course) That'll show everything that that USB device is set up for, as reported by the device itself. (it'll be long)

I don't see audio in there. So I don't think the camera does it at all. You might be able to record audio, internal to the camera, but it won't do audio on USB.

 

[vertifor922]

So even if you connect a microphone to the socket for an external microphone that the camcorder is equipped with, also in this case it won't be seen by the PC?

 

[AaronD]

I think that's true. It's weird, but I don't see audio in the USB descriptors that you posted.

 

[vertifor922]

Thats what I got from the command you give told me to insert.
At this point I thought one thing, can you tell me if it can work?
In practice I would record the video via Obs and the video camera while for the audio I would add another audio source to Obs, ie an external microphone.
I just think you need a sound card, in practice you enter a nice sound card with the microphone and then exit the card via USB and enter the PC, so can it work?
Otherwise I have this multitrack recorder

MR-16HD : 16 Track Digital Multitracker

Could I use this as an external sound card?
This device has USB port but in USB mode it only transfers the data saved on it to PC but it doesn't work for other purposes.
But I see that behind it has a socket for the digital output with an optical cable, could I use an optical cable to take the output from this socket and bring it to the PC?
In practice, with the microphone I would enter the Fostex MR16, then I would take the audio from the digital output of the MR16 via optical cable and take it to the PC, so it would work as an external sound card?
Only the PC doesn't have an optical cable input, are there optical to USB adapters?

Sounds to me like you've been buying a bunch of cheap single-purpose gear for something else, and then trying to make it do this. If you're buying more gear to do this anyway, look for gear that can do this, instead of single-purpose something else.

There are adapters from practically everything to everything else, but I think you need to step back first and redesign everything for what you're actually doing. You still haven't said what that is.

I have to make simple videos, to be uploaded to the network so I only need to be able to acquire video and audio, I can acquire the video by adding the video camera as a video source to Obs, I lack the audio because my video camera does not send it via USB, so I have to add another audio source to Obs, the fostex I had there for some time and I wanted to try to reuse it, but only as a sound card to make Obs see a microphone connected to the Fostex as an audio source, that's all.
In short, I'm just trying to have an audio source to add to Obs (other than the one from the PC microphone) as the video camera audio is not recognized.

 

[AaronD]

So you're effectively doing "live to tape", using OBS as the producer and recorder. One camera so far, and one mic. Good so far?

It's worth a shot, to see if the multitrack recorder is also a sound card, but I wouldn't count on it. It may also be a recorder only, to its own storage, and then a flash drive to the PC.
Or it might be a multitrack sound card. OBS doesn't do well with those either. It mixes down everything it can find and then presents that mix as a single source. Not good if you have a bunch of individual things on other channels, in addition to the stereo mix that you want on a specific two. I found that out the hard way, and it took me forever to figure out that that's what it was doing.

If you're never going to need anything beyond that one camera and mic - no intro graphics or other pre-done videos, no overlays, etc. - then you probably don't need OBS at all. Just that camera with a mic plugged directly into it (assuming that it does work that way), and record in the camera. Either upload that directly, or run it through a video editor to add the other stuff in post-production.
Either way, set the camera for the highest possible quality, at the expense of file size, and give it a big enough card to make that work. If there's a super-high-quality format that is supposed to be only for the camera, that can still be okay. My camera does that, with a weird file extension and in a different folder from everything else, but I know where it is and my editor is perfectly okay with it.

 

[vertifor922]

I saw that the Fostex has a USB mode but it only works to transfer data from the Fostex to the PC, everything else doesn't work.
It also has a Toslink socket for optical cable though, it's a digital audio socket, I was thinking of trying to bring that audio to the PC but I can't find a Toslink to USB adapter.
Or you could take the audio jack output from the Fostex and bring it to the PC but here too a sound card would be needed, so I would have to buy it and connect it to the Fostex, maybe I'll buy a microphone like this first, which already has its own sound card

https://www.amazon.it/dp/B07WKM5ZCS/?coliid=I1XJUUTQV6TSOO&colid=1NY13V2K07LIC&psc=1&ref_=lv_ov_lig_dp_it

and add it as an audio source to Obs, so I would take the audio from this microphone and the video from my external camera.

Depending on what you're actually doing (not how, but what - that question is personal, not technical), that might be enough, or it might be too noisy.

That noise comes mostly from a dirt cheap, "works and that's all," analog to digital converter and circuitry to drive it. Probably 16 bits, and technically better isolated from the PC's noise than an internal converter would be, but still not designed *well*. Leaving enough headroom to avoid clipping, on something like that, results in a fairly low signal-to-noise ratio.

Better S/N would be the same mic (or almost any mic) feeding something like a Behringer UMC202, which has 24-bit converters, intentional circuit design, and a gain control to put your signal at exactly the right level for the converter. It's a bit more expensive than what you linked, but MUCH better!

But if you or your audience are not going to appreciate better, then what you linked will work.

 

[vertifor922]

I have a Shure SM57 microphone, oit would be fineP I could use that but you need a sound card, can you recommend one with good value for money?

 

[AaronD]

Great! Old standard, bulletproof, and still sounds good even today...for most things. That and the SM58 vocal mic are the same thing with different grilles. If you're studio-mic'ing a band, you probably wouldn't use one, but anyway...

The Behringer that I linked to last time is probably your best bet. Same preamp and converter as in their digital live consoles, and standards-compliant USB, so it really does work with everything. (unlike the cheaper ones that roll their own and is only guaranteed on the exact serial number of PC that they tested it with) I have one; not a problem whatsoever.

Of course, you'll need an XLR -> XLR cord from that mic to the interface, but if you have the mic, I assume you have the cord too?

 

[vertifor922]

YES I have a "Cannon" type cable they are cables that have 3 pins inside, I took a look at the Behringer you indicated, inputs 1 and 2 are Cannon inputs where can I connect my microphone? Shouldn't they have 3 holes to accommodate the 3 pins? Canno and XLR are the same thing? I have the Canno cable which would fit into the input of this one https://www.amazon.it/Focusrite-Int..._1_19?__mk_it_IT=%C3%85M%C3%85%C5%BD%C3%95%C3 that it seems to be made more for recording the guitar, would the vocals be recorded badly?

The Behringer has combo jacks, that will take both XLR and 1/4" (6mm) TRS. (one at a time, of course) That's handy too.

What makes a guitar input special is "high impedance", or Hi-Z, which means it doesn't load down an "artsy" circuit that is sensitive to that sort of thing. But the drawback is that it's also easier for noise to get into it when there's nothing at the other end of the cord. When you plug in a guitar, the guitar's impedance reduces the noise so something that's...okay (you still don't want excessively long guitar cords), and the XLR mode is low enough impedance to kill that noise regardless. A DI box has a 10:1 step-down transformer in it, that does the conversion to Lo-Z that can drive a long cable run (100m snake, for example, from stage to the mixing position in the audience), as well as isolating grounds to get rid of a power-line buzz. None of that has anything to do with the content of the signal.

The combo jack has switches built into it, so it's only Hi-Z with a TRS, not XLR or empty.

I have two mics in mine: a Behringer XM8500 (SM58 clone), and a cheap "shotgun" mic, which has a long barrel and is even more directional. Different gain settings for each because of their different sensitivities, and phantom power turned on because the shotgun mic needs it (the other one doesn't care). Perfectly fine.

 

[vertifor922]

So if I understand correctly, you advise me against the Focusrite for guitar and instead you recommend the Behringer by connecting my Shure SM57 to the Behringer.
I currently have a cable like this
https://www.amazon.it/XLR20MM-Cannon-Audio-Casse-Effetti/dp/B01AARW7O4/ref=sr_1_9?__mk_it_IT=ÅMÅŽÕÑ&crid
What cable exactly should I buy to get my Shure SM57 into the Berhinger?
I can't find any compatible with that connector, looking for XLR I always find Cannon cables like the one I already have, the ones with 3 pins.

If you already have the Focusrite, and it really is what the picture shows, then that'll work just fine. Put the guitar and mic in their respective jacks, and it should "just work". If you don't have anything yet, I'd recommend the Behringer as a more flexible thing.

Either way, it'll come into the PC as a single stereo signal, with one source hard left and the other hard right. OBS will take that as a single stereo signal, which is not what you want. However, you can set up two copies of that stereo source in OBS, use the Advanced Audio Properties to Balance each one hard to one side or the other, and then Mono that to give you independent controls for each. OBS's Filters will probably not work as you expect though, because all of them see and respond to both signals.

If you really need separate control of each, look at a DAW (Digital Audio Workstation) of some kind that will take a single stereo input and treat it as two mono's, then process and mix them in the DAW, and bring the final signal into OBS as an unchanged passthrough.

DAW's are all over the place in terms of price and functionality. There's a pretty good chance you'll find a free one that may not be professional-recording-studio quality, but does what you need. Shop around a bit.

I don't have the Focusrite, but would the Focusrite also be good for recording vocals?
I'm sorry but I didn't understand which cables go from my Shure SM57 to the Berhinger, you said they are XLR, but if I look for XLR cables on the net I find the Cannons, the ones with 3 pins like mine that I already have, but it's different from the inputs of the Berhinger, this I cannot figure out.

Different things may be advertised for one thing or another, but the signals don't care. They're just trying to appeal to a specific market. And if they end up confusing people into buying one for each use, then they make more money that way too. If you get one that's designed and built well, regardless of how it's advertised, it'll be great for everything.

As you can see in my video (direct from phone-on-a-tripod to YT), the Behringer is quite flexible in what it can do. My gain controls are all the way up because the mic is far away for this demo and I wanted the signal lights to come on. (you're listening to the phone mic, not the pro one) You'll probably have them lower than that, and maybe the pad button too, if your guitar or voice is that hot.

Do some practice takes, watch the meters, and adjust accordingly. Leave enough headroom that you don't have to think about not-clipping while you're performing, and let someone else set up a decent mix in whatever software you end up with...or do that yourself too, by recording raw (after the gains are set), and playing that back through the processing that you're eventually going to use live.
(That's called a "virtual sound check", to use a pro term, and it can also be done with a full band, recorded raw as individual tracks and played back through the live processing and PA. That way the band can show up later, jump on stage in front of an audience, and just go.)
