Blank screen with Hardware Decoding in Linux with Nvidia

Hello,

It says it all in the title. The client OS is Linux (OpenSuSE Tumbleweed) while the server is Windows. I try to run a game and it simply loads a blank screen where I can hear the audio of the game but the 'Performance Information' shows that it is capturing 0x0 size screen.

I have tried 'STEAM_RUNTIME_PREFER_HOST_LIBRARIES=0' and 'STEAM_RUNTIME=0'. Of course, this can cause Steam to ignore libva all together and use software decoding. I also tried running steam as root to see if there was some permissions issue. I have tried disabling hardware encoding on Windows (just for kicks that would not be a true solution), and that still doesn't work. This only works when using software decoding.

OS: OpenSUSE Tumbleweed
uname: Linux linux-zc2m 4.16.7-1-default #1 SMP PREEMPT Wed May 2 19:21:16 UTC 2018 (938738d) x86_64 x86_64 x86_64 GNU/Linux

steam console output that appears to show there issue:

....

ffmpeg verbose: Opened VA display via X11 display :0. ffmpeg verbose: Initialised VAAPI connection: version 1.1 ffmpeg verbose: Matched "Splitted-Desktop Systems VDPAU backend for VA-API - 0.7.4" as known driver "VDPAU wrapper". VAAPI hardware decoding ffmpeg verbose: Reinit context to 2560x1088, pix_fmt: vaapi_vld ffmpeg error: Failed to upload decode parameters: 15 (the requested VABufferType is not supported). ffmpeg error: hardware accelerator failed to decode picture Marking frame 0 complete with status k_EStreamFrameResultDroppedDecodeCorrupt client/streamdecoderh264avcodec.cpp (481) : Assertion Failed: Unexpected frame format -1

So the two main things I see of interest is:
1) Assert( Assertion Failed: Unexpected frame format -1 ):client/streamdecoderh264avcodec.cpp:481

2) ffmpeg error: Failed to upload decode parameters: 15 (the requested VABufferType is not supported).

The only thing I can think of now is to compile libva and ffmpeg manually and see if I can get them to be happy. But I am not sure that will do it because of the 'Unexpected frame format -1 ' coming from the steam code.

So yeah. Does anyone else have issues with hardware decoding in Linux? Any help would be appreciated.
