vlc does not run video extension with AMD RX 550 Driver

[pr0m3th3us]

I use Ubuntu 18.04 64 bit, and I'm having a small problem, where I can not make videos through Vlc after installing the Video Drive of the AMD Rx 550.
The Vlc will run, but without running any video extensions.
A dream is one test to remove the drive for so really even this, then I noticed that is this same.
The video drive I downloaded on the AMD website and being a technical version for the architecture of my Ubuntu that is [amdgpu-pro-18.20-606296].

I was able to check the system logs for the error that appears.
With the AMD rx 550 Drive installed I can not play the videos. so can you solve this problem without removing the video drive?

Hello!

Please use the default font size.

Also, please do not assume that everyone here is a male.

Your post doesn't make sense to me. You say you've installed amdgpu-pro, but glxinfo shows the default open-source amdgpu driver.
I would recommend sticking with the open-source driver unless you need a feature that the Pro driver offers.

There are Qt5 segfaults in your logs. There is no indication it is related to the video driver. Maybe if you gave a log from VLC with each driver (and clearly labelled which one was which), it would make more sense.

I'm also wondering how you installed VLC (.deb package or Snap?)

[pr0m3th3us]

greetings everyone.
My vlc is give version of ubuntu 18.04, it came installed by default was an apt-get package, it was running until I install this drive from AMD. but now it does not run the video extensions, but if I just run vlc without opening any extension it opens without opening any files.

I apologize, it was not my intention to want to offend anyone.
I'm really sorry.
