Streaming on Linux

I don't do a lot of streaming, but I have been streaming some 3D printing on Mixer.

I've taken a break and have decided to redo my internal network and add a lot of new hardware. I picked up a Clevo N240BU and installed Ubuntu on it. Would anyone here have an idea if this laptop would be good enough to handle streaming 2 cams, one on me and a second cam. I would think the only bottleneck should be my internet connection.

 

Well, your chip supports Intel's VAAPI hardware acceleration, and should work just fine with OBS studio.

 

Running OBS (Arch Linux packaged version) on a dual-GPU system. VAAPI is available according to vainfo, but OBS only shows software and NVENC. Any idea about what to check first?

 

What's your hardware setup?

lspci and the graphics switching method you use would suffice.

 

Intel HD 4600 + NV GTX765M on a Clevo W230ST. All drivers on latest stable.

Running OBS through Bumblebee ($ optirun obs) or not makes no difference in terms of hardware encoding support detected, which seems to indicate OBS is looking for the relevant files rather than actually making any calls to test support. If I run OSB through Bumblebee NVENC works as expected.

OSB's console output doesn't mention anything about VAAPI. It does say NVENC being supported.

Some relevant output:

Code:

$ lspci|grep -i 'nvidia\|graphics'

Hmm, you may need to build the package from source, and configure FFmpeg to use VAAPI too.

I wonder if there's an AUR package for that..

You may try using hints from this post, I remember guiding this user on the same, but on CentOS: https://obsproject.com/forum/threads/finally-centos-7-3-intel-mss-obs-vaapi.76577/
