Original GitHub issue: https://github.com/games-on-whales/wolf/issues/320

After setting up wolf on my host device whenever I try to connect to the wolfui or the test ball containers I only see a black screen. I read in the troubleshooting guide and thought this was just wolf taking a while to download all of the docker images, but the image never showed up. Additionally when I click on the test ball I still see a black screen, but I hear the sound being played.

After playing around with some moonlight settings I was able to get a video output from wolf only when I switch the video codec to H.264 instead of having it be automatic.

I'm using NixOS and the GPU I'm using is just the integrated iGPU which is an Intel HD 530. From what I read online the iGPU should be able to support HEVC and, if it can't, then I'm curious as to why Moonlight isn't requesting the H.264 codec which seems to work.

Thanks for any help!

From the logs it seems that Wolf is able to detect HEVC in your card but then fails to actually encode a frame using it. This could be either an option in our encoding pipeline that isn't supported or something to do with the zero copy pipeline where the input DMA buffer can't be used for some reason.

You can play with the encoding options in your config.toml by editing this block https://github.com/games-on-whales/wolf/blob/stable/src%2Fmoonlight-server%2Fstate%2Fdefault%2Fconfig.v6.toml#L382-L389

Or you can try disabling the zero copy pipeline by adding the env variable WOLF_USE_ZERO_COPY=FALSE

Okay, so I did a bit more testing and I was able to get HEVC encoding to work. I first tried adding the env variable WOLF_USE_ZERO_COPY=FALSE but that didn't change anything.

After that I removed that line and decided to see if commenting out the va HEVC encoder plugin section that you linked would change anything and it worked, so it would seem like the intel HD 530 doesn't want to play nicely with the va plugin on my system for some reason.

I did have one other question regarding the config.toml file. I noticed that in the file you linked that the gstreamer definitions are at the end of the toml file after the profiles, but in my config file they come right after the uuid before the paired clients. my config file also is missing the explanatory comments. Is this typical behavior or did I pull an older image where the default config file is different?

Nice, commenting out the VAAPI encoder made it fallback to QuickSync and that seems to work for you. I've recently changed that default after some users were affected by the opposite: qsv wasn't working whilst va whilst using the new-ish discrete Intel GPUs.

I noticed that in the file you linked that the gstreamer definitions are at the end of the toml file after the profiles, but in my config file they come right after the uuid before the paired clients.

The order in which the top level keys are defined doesn't matter in TOML, you can move them freely in the file, also...

my config file also is missing the explanatory comments

... the library that Wolf uses for writing the TOML config file doesn't properly support them. The file has been written by Wolf when you pair a Moonlight client (for persistence) and that's what caused the difference with the default one in our repo. All good and normal 😉
