Will graphic card help with streaming using a weak cpu?

[John Sam]

Hi

I have a nas using this cpu
Intel® Atom® Processor C3758

On this board
https://www.supermicro.com/en/products/ ... i-8c-hln4f

Streaming using vlc is working for 1080p however it is slow when zapping between 5 mp4 files that I stream

The question is. Will a graphic card help to make streaming work smoother?

I want to buy this
Gigabyte GeForce GTX 1660 Ti OC 6G’?

This graphic card support encoding..

By the way. I am using debian . Vlc command line. No Ui

Video cards have h264 HW Accelerated Encoder & Decoder...
Intel 4th gen does Not work well,
needs VDPAU drivers to convert VAAPI to OpenGL,
some apps dont work well with OpenGL like Telegram Desktop,
others work Ok, Like Firefox,

it depends on the software how well is implemented...
Nvidia has several drivers for Kubuntu, Propietary and Open source X.org
propietary work best for GT 740.

Usually HW accelerated h264 video Encoder & Decoder is similar in HighEnd and Lowend GT 1030,
you need to test.
Later gens also have h265,
h265 in older HW does Not decode accelerated, and requires high cpu.

Test the codec, different versions... some work, some dont.

Anyway... that CPU does Not have Inegrated Graphics

ASPEED AST2400 BMC
is very basic, more basic than intel iHD gpu.

Hi

I use debian server only with vlc. No other software
And i need only h264 video codec
And only 1080p max
Do you think graphical card will improve performance?

Will vlc offload encoding to graphical card and and not to cpu?

Please note that i am using vlc command line only without a gui. Will command line by default use graphical card or is there some argument i need to pass to vlc command line?

If the hardware encoder has OS drivers and the corresponding VLC support plugin enabled, yes, otherwise no.

Hi

I guess with hardware your mean the graphic card

I want to buy this.

Gigabyte GeForce GTX 1660 Ti OC 6G’

How to find out if this has the necessary drivers?


I am new to building an own server

[Rémi Denis-Courmont]

If you install the NVENC drivers and VLC plugin, it should be possible. Don't ask me how though.

[John Sam]

Hi

do you mean with vlc plugin this package "vlc-plugin-qt" ?

I have followed this istructions.
https://www.linuxcapable.com/how-to-ins ... -bullseye/

but I don't think it is working yet.
root@pve:~# nvidia-smi
NVIDIA-SMI has failed because it couldn't communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

this is weired because driver are installed.

I did a reboot
and secure boot is disabled in the BIOS

any idea how to make VLC command line, use by graphic card ?

No, I don't mean Qt when I write NVENC.

[John Sam]

hi,

thanks. as you maybe have noticed, I am new. and it is not easy

I read this : If you install the 2) NVENC drivers and 2) VLC plugin, it should be possible. Don't ask me how though.
I am talking about point 2. VLC plugin . what is this ?is this kind of another binary that you need to run next to vlc.
I have installed only VLC using this command :

root@pve:~# apt install vlc
Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
vlc is already the newest version (3.0.17.4-0+deb11u1).

By the way. I think drivers now installed
i downloaded from here:
https://www.nvidia.com/content/DriverDo ... type=TITAN

running this command: bash NVIDIA-Linux-x86_64-515.48.07.run --kernel-source-path /usr/src/linux-headers-5.11.22-5-pve/ --glvnd-egl-config-path /usr/include/glvnd/
(from here https://forum.proxmox.com/threads/vgpu- ... nel.63255/)

I can see now ouput.

Only thing left is VLC not using this GPU. how to make VLC use GPU ?

[unidan]

Hi, we don't have an nvenc encoder upstream yet unfortunately so VLC cannot use it for encoding. It can use it for decoding though.

[John Sam]

hi,

thanks I see

it is only GPU decoding. https://wiki.videolan.org/VLC_GPU_Decoding/
Not encodinig.
I will try to use the graphic card for gaming and stream to my living room. Hopefullly NAS can handle.
