I read the ALVR Wikis here and here

Bug reports:

When trying to figure out why I couldn’t connect my headset when it paused on “The stream will begin soon”, I looked into vrserver.txt to find that the following message jumped out at me.

Fri Nov 26 2021 16:43:49.058711 - alvr_server: error in encoder thread: failed to load libavcodec.so.58

As a result, I tried to do several things to try and remedy this.

I tried to install the appropriate libavcodec packages to see if that would solve this. It still couldn’t find the library.
I tried to use the ALVR dashboard to register the drivers and saw that /usr/lib64/alvr was added. It still couldn’t find the library
As a last resort, I added the folder /usr/lib64/alvr to path and ran ldconfig and that still didn’t work.

I can’t seem to figure out why it can’t find it and I don’t really know anything about how plugins interact with Steam.

Running Ubuntu 20.04 LTS, with Oculus Quest 1, NVidia RTX 2060. I found the same error “failed to load libavcodec.so.58”. Digging a bit deeper, I ran: ldd /usr/lib64/alvr/libavcodec.so.58 and noticed libx264.so.160 => not found libx265.so.192 => not found

The libraries included with this Ubuntu release are: libx264.so.155 => /lib/x86_64-linux-gnu/libx264.so.155 (0x00007f1776581000) libx265.so.179 => /lib/x86_64-linux-gnu/libx265.so.179 (0x00007f1775613000)

So that tells me I need newer libraries to work with the libavcodec alvr bundles.

I manually downloaded: http://archive.ubuntu.com/ubuntu/pool/universe/x/x265/libx265-192_3.4-2_amd64.deb http://archive.ubuntu.com/ubuntu/pool/universe/x/x264/libx264-160_0.160.3011+gitcde9a93-2build1_amd64.deb Extracted them with ar x [file.deb] and then tar xvf data.tar.xz Copied libx264.so.160 and libx265.so.192 to /usr/lib/x86_64-linux-gnu Ran ldconfig. Looking back I suppose I could have just used dpkg and installed the packages, but I first tried placing just the library files into /usr/lib64/alvr with the others. That didn’t work so I copied them to the system-wide directory.

Restarted alvr and it worked. Sort of. The h265 codec just looks like smeared blocks of random grey. Using h264 is functional, especially once I switched to a wired USB connection. And I had to turn off foveated rendering because the outside areas were all stretched incorrectly.

@vclayton 's suggestion solved my libavcodec.so.58 can't be found issue. Thank you! However the next problem occurs with [INFO] | failed to create VAAPI encoder.

Anyone any suggestions there?

Guessing you have a Nvidia gpu if so clone the v16 release and follow the build and run instructions, as rn Nvidia GPUs can only use software encoding which is broken on the git / nightly releases. Also that normal again if you have a Nvidia gpu

Just got my Quest today and had the same issue as described here; first the libraries missing and then the VAAPI failing because of NVidia.

Hope the software encoding can be fixed in the build as well as full support for Nvidia

@ColdIce1605 thanks i have indeed a Nvidia GPU. That sucks, will there be support for Nvidia someday, or is the only way getting an AMD card? (Which i’m planning to get anyway.)

Hello @xytovl , same issue here, this is the content of ~/.config/openvr/openvrpaths.vrpath

	],
	"external_drivers" :
