4 streams 4k simultaneously

[tesara]

Hi I would like to stream from iptv and satellite up to four 4k channels simultaneously to record sports events from various channels. To play properly 4k i need to have hardware acceleration disabled. When playing 3 or 4 4k videos they are choking. I have Intel i3 10105. When i will switch to 12 gen Intel i5 12400f that will help? Thanks.

Have you checked the CPU and GPU usage ?

[tesara]

100% CPU and 28% GPU.

Too much stress for your system.

Intel 12400 will handle this?

Or maybe how to properly set hardware decoding? I have tried multiple settings with all settings and only disabled is working with 4k video's.

I really have no idea, how could I know ?

That's why you are using so much CPU. But TBH streaming four 4k streams simultaneously seems to be overkill to me, especially if your record them (lot of hardware accesses).

How I can play 4k video's with hardware decoding? I have tried several settings with automatic/direct9/direct11 with all output settings and all deblocking filters and I have problem with playing 4k files. They play few frames and then image stop and is only sound. I have up to date graphic driver.

Depends on the codec being used and the abilities of your graphics card.
On Windows 7 and above, Direct3D11 is the best choice.

Tools -> Preferences -> Video
Output = Direct3D11
Tools -> Preferences -> Input/Codecs
Hardware accelerated decoding = D3D11 Video Acceleration

When doing so, image show few frames and then freezes and is only sound. I have GTX 1060.

Please open Tools -> Messages (set Verbosity to 2) before you start the playback, and then paste the full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.

Also upload a short sample of your original problematic file to Zippyshare.com or to WeTransfer.com and then post the link to the file here.

If needed cut it with DGsplit and read here about how to do it:

200 MB max should be enough.

You GTX 1060 should be able to properly handle this file:

Code: Select all

Format : HEVC Format profile : Main 10@L5.1@High Bit rate : 9 559 kb/s Width : 3 840 pixels Height : 2 160 pixels Display aspect ratio : 16:9 Frame rate : 50.000 FPS Color space : YUV Chroma subsampling : 4:2:0 (Type 0) Bit depth : 10 bits Color range : Limited Color primaries : BT.2020 Transfer characteristics : HLG Matrix coefficients : BT.2020 non-constant

You should create a new report ticket on the VLC Trac with your above report, the links to your files and the link to this thread:

One issue that 3 4K HEVC streams might be using too much memory from the GPU. In 4.0 we use less memory for hardware decoding. In 3.0 you might reduce that amount by using a single decoding thread (instead of 3 you seem to set).
