Steam streaming issues ffmpeg

as the title says, i'm having issues getting steam game streams to work.

by running it from the command line, i've obtained the following log:

Code: Select all

the only contributor to the stream failing i can think of is this:

I've tried to get ffmpeg to work, but no luck.

trying with a random video file i had lying around and regular ffmpeg (following command):

Code: Select all

ffmpeg -threads 1 -i random.mkv -vaapi_device /dev/dri/renderD128 -vcodec h264_vaapi -vf format='nv12|vaapi,hwupload' output.mp4

i get the following:

as seen above it segfaults.

Are you running it as root?
Maybe you shouldnt.
In ~/.bashrc
include a line like

Code: Select all

export  LIBVA_DRIVER_NAME="i965"

Then

Code: Select all

source ~/.bashrc

substituting i965 with your driver.
You can check them in

Code: Select all

/usr/lib64/va/drivers

Plz try

Code: Select all

USE="vainfo" emerge -1av libva-utils
then as ordinary user
vainfo

Is
libva
installed?

No, it's running as a regular user

the error from steam would indicate that it can't find the correct driver.

it's the same error i got from standalone ffmpeg when i mistyped the driver name.

still doesn't explain why ffmpeg is segfaulting though

libva is installed, as well as libva-compat
