Linux client hardware decoding

[optimistaescarmentado]

Hi,

first congratulations for this great program.

I have one Windows server and one Linux client, everything works ok but Linux can’t decode in hardware.

Linux is Ubuntu.

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 18.04.3 LTS
Release:        18.04
Codename:       bionic

Anyone has a solution?

Thanks

The problems seems to be in libva1, these lines are in the client logs:

So please try this:

cd /usr/lib/x86_64-linux-gnu/
sudo ln -s libva.so.2 libva.so
sudo ln -s libva-drm.so.2 libva-drm.so
sudo ln -s libva-x11.so.2 libva-x11.so

Thx, that was it.

I thought ldconfig make always those links.

Now hardware decoding is working, although my cpu is 135%, a little worse than with software decoding.

If you want me to make more tests just tell me.

Thanks a lot

Normally hardware decoding offloads the CPU, but this could not happen with particular combinations of hardware and drivers. Unfortunately this is not something that our software can have control over.
