Original GitHub issue: https://github.com/games-on-whales/wolf/issues/383

Hi, I have an old processor (i5-3350P) and GPU (AMD Radeon 290X) and cannot get Wolf to work. Not sure if to post here or in gst-wayland-display repo

OS is Ubuntu 24.04.4 LTS

I get a few warnings that seem relevant:

Before an error:

wolf-1 | 15:09:44.795752483 ERROR | [GSTREAMER] Pipeline error: Internal data stream error.

It's an issue with gstreamer I think, and I can get Wolf UI to work when I use the following environment flag:

WOLF_USE_ZERO_COPY=FALSE

However, it is too slow to use.

I have installed Sunshine separately for reference / testing and that works perfectly and fast.

Has anyone encountered this before? I'm using the docker image ( image: ghcr.io/games-on-whales/wolf:stable )

Here is the full log:

Originally created by @BlackFoxController on GitHub (Apr 3, 2026). Original GitHub issue: https://github.com/games-on-whales/wolf/issues/383 Hi, I have an old processor (i5-3350P) and GPU (AMD Radeon 290X) and cannot get Wolf to work. Not sure if to post here or in gst-wayland-display repo OS is Ubuntu 24.04.4 LTS I get a few warnings that seem relevant: ``` wolf-1 | 15:09:33.946338938 INFO | Using h264 encoder: va wolf-1 | 0:00:00.465298948 1 0x61b412713030 WARN GST_ELEMENT_FACTORY gstelementfactory.c:713:gst_element_factory_make_with_properties: no such element factory "vah265enc"! wolf-1 | 0:00:00.465353986 1 0x61b412713030 WARN GST_ELEMENT_FACTORY gstelementfactory.c:713:gst_element_factory_make_with_properties: no such element factory "vah265lpenc"! wolf-1 | 15:09:33.947637323 INFO | Using h265 encoder: x265 wolf-1 | 15:09:33.947660719 WARN | Software h265 encoder detected wolf-1 | 0:00:00.466578032 1 0x61b412713030 WARN GST_ELEMENT_FACTORY gstelementfactory.c:713:gst_element_factory_make_with_properties: no such element factory "vaav1enc"! wolf-1 | 0:00:00.466607442 1 0x61b412713030 WARN GST_ELEMENT_FACTORY gstelementfactory.c:713:gst_element_factory_make_with_properties: no such element factory "vaav1lpenc"! ... wolf-1 | Failed to create GsDmaBuf ... wolf-1 | 0:00:11.307070920 1 0x7613200012d0 WARN basetransform gstbasetransform.c:1371:gst_base_transform_setcaps:<videorate0> transform could not transform video/x-raw(memory:DMABuf), format=(string)DMA_DRM, width=(int)1920, height=(int)1080, framerate=(fraction)60/1, drm-format=(string)NV12 in anything we support ``` Before an error: `wolf-1 | 15:09:44.795752483 ERROR | [GSTREAMER] Pipeline error: Internal data stream error.` It's an issue with gstreamer I think, and I can get Wolf UI to work when I use the following environment flag: `WOLF_USE_ZERO_COPY=FALSE` However, it is too slow to use. I have installed Sunshine separately for reference / testing and that works perfectly and fast. Has anyone encountered this before? I'm using the docker image ( image: ghcr.io/games-on-whales/wolf:stable ) Here is the full log: ``` wolf-1 | [2026-04-03 15:56:47] wolf-1 | [2026-04-03 15:56:47] [ /etc/cont-init.d/10-setup_user.sh: executing... ] wolf-1 | [2026-04-03 15:56:47] **** Configure default user **** wolf-1 | [2026-04-03 15:56:47] Container running as root.

Have you tried forcing H264 from the encoder settings in your moonlight client?

Hi, just tried it. It doesn't make a difference.

It does because your GPU doesn't support anything else than H264 and in the logs you've posted above the client was asking for HEVC. Can you run it again and post the logs with added env variable WOLF_LOG_LEVEL=DEBUG?

Thank you, here is another log with the WOLF_LOG_LEVEL=DEBUG config

Note/ added: I am on Xubuntu, using xfce, maybe the issue is there. It does not have Wayland (but x11 should be available).

I guess your HW really is too old to support our zero copy pipeline, have you tried using WOLF_USE_ZERO_COPY=FALSEwith the H264 encoder though? It should be good enough for some light gaming.

I haven't tried any games, but when I enable it that way (h264 with WOLF_USE_ZERO_COPY=FALSE) it's very slow. The cursor moves with crazy lag, and using the keyboard to select apps is also very slow. Same when entering the desktop app. Very low framerate.

It's not the case with Sunshine (very fast). But I'm guessing the architecture is very different (here the hardware is meant to split / distribute the frames to each session), where in Sunshine it's only one render.

Quick update: I switched to Arch Linux with KDE Plasma and Wayland, installed the docker container and it worked out of the box. Using the automatic hardware encoding was still very slow, but forcing it to h264 and it works perfectly. No .env flags are set.
