How to use OBS-studio for streaming audio-video on FreeBSD.

Hello to everyone.

I would like to configure OBS studio on FreeBSD to stream the audio video from my home using the Kinect 2 embedded audio-video chipsets,but I'm realizing that the "OBS Studio Plugin: Output as Video4Linux2 device" does not work under FreeBSD,even if the port can be installed. Do you know if there is a workaround ?

I would probably try getting a cheap webcam to work first. Geezer on these forums seems to have found some success with that. My thinking goes, if you get that to work, then OBS Studio will work, too. Good luck! :)

I want to stream on a web site what my camera is seeing inside my room (me and my ugly face) :

I think that I have installed the required libs,but the error below persists. First of all I tried to configure my very very old web cam :

Creative LabsWebcam Plus (CT6840)
should work​
0x05a9​
0xa511​
OV511+​

to make it work directly on FreeBSD. This is how I have configured it :

Code:
nano /etc/rc.conf

kld_list="cuse4bsd"
webcamd_enable="YES"

and then with the tool pwcview I have displayed on my desktop what the camera was seeing, like this :

Code:
pwcview -s uxga -f 30

and it worked. But unfortunately it didn't with obs-studio. Infact as soon I've launched it,I've seen the error below :

Code:

obs-studio worked despite this error,but it is not able to recognize my webcam,so I can't add it as source.

Thank you astyle.

I did install OBS Studio and V4L. The webcam worked. I did not use it for streaming. You possibly could. The webcam I used is a standard USB Logitech.

Really, I did not like OBS Studio, it is not intuitive and the layout is difficult (IMO only). I have since uninstalled it.

I am sure you can get streaming working. There are may packages around. You could look at multimedia/cheese.

In general, multimedia under Freebsd can work quite easily, often surprisingly out of the box. Sometimes, you may have to build a port with different configuration options. But broadly, in the latest version of Freebsd (13.0-RELEASE-p6) and with quarterly ports, you can do an awful lot.

One thing you must make sure, ziomario : Keep it simple.

KEEP IT SIMPLE !

Don't use convoluted towering piles of unrelated, unsupported stuff, as is your want. You will just get frustrated and not learn anything.

If you only want to talk and share video with one other party (or a very few), then don't stream. It is fairly simple to get skype for web working in chrome browser and zoom meeting working in firefox.

there is no native chrome browser on FreeBSD,only Chromium. I ran chrome with the linuxulator inside the chroot and it didn't work as normal user and as root :

the person I want to talk to does not use Zoom. She can't. I could stream my face on the web using cheese and some other streaming tool that at the moment I can't figure out.

Yes. So use chromium. It works a treat.

and it didn't work as normal user and as root :

Do it the hard way if you want.

the video call does not work in chromium using skype. And Im using an old webcam (not the kinect,that seems to be harder to use even in Linux). Hear me : can u suggest a nice streaming tool ? I want to stream my face on the web to port 80 capturing my face with :

Code:
pwcview -s uxga -f 30

,before all.

I believe OpenCV still works well on FreeBSD to capture webcam footage.

I have some random code here to stream to a webpage:

https://github.com/osen/tstream

If you are a bit handy with simple programming, you should be able to get it to work. It is very rough but is the only thing I have public at the moment that I am also somewhat familiar with. I am sure there are better all over GitHub, especially with the popularity of the Raspberry Pi these days.

ziomario does listen, but root has become like carpet slippers: <https://old.reddit.com/r/freebsd/comments/s3be9y/-/hsm4smz/?context=1> :)



I can't complain. I'll probably never learn to use the right control key (see †) after years of making things uncomfortable for myself. Back-tabbing with one hand is, if you like, my worn-out carpet slipper that I'll never shake off :)

you are right,I should not use root,even if at home I want to relax myself from the outside millions of dangers. But its only a psychological thing,not a lack of knowledge or swagger.

I believe OpenCV still works well on FreeBSD to capture webcam footage.

I have some random code here to stream to a webpage:

If you are a bit handy with simple programming, you should be able to get it to work. It is very rough but is the only thing I have public at the moment that I am also somewhat familiar with. I am sure there are better all over GitHub, especially with the popularity of the Raspberry Pi these days.

who knows if in this case @Geezer,reading that,would have said what he said to me :

One thing you must make sure, @kpedersen : Keep it simple.

KEEP IT SIMPLE !
