Is there an existing issue for this?

  • I have searched the existing issues

Current Behavior

Client does not connect - you can spam "Streaming" button , but no stream is started

Expected Behavior

  1. Load a game in Steam Container on Server
  2. Start a Steam client on a Client
  3. Try to start game session via streaming on a client
  4. Game launches in container
  5. Stream starts on a container

Steps To Reproduce

  1. Load a game in Steam Container on Server
  2. Start a Steam client on a Client
  3. Try to start game session via streaming on a client
  4. Game launches in container
  5. Client does not connect - you can spam "Connect" button , but no stream is started, but it indicates that server correctly starts a game and reports that it is ready for streaming

    This image is only made to access and play games via a web browser, it is not meant to do what you are doing I would highly recommend using Games on Whales for your usecase and leveraging Sunshine/Moonlight.

    I mean it is technically possible, but it breaks from the purpose of this image, stuff like GOW locks the resolution and uses gamescope to specifically create a compatible env while the target here for this image is to actually play the games using your web browser.

    The userspace gamepad interposer could definitely be messing with it, I know steam remote play needs udev and such to properly setup its remote controllers.

    I agree, but yours image have some advantages:

    • No need for dummy plug (like with steam-headless)
    • Single image app
    • Installable on TrueNAS like systems

    Also i dont think problem is in gamepad interposer, i added some logs to the post above

    Problem was in my setup - hardware accelerated streaming does not work, but if i disable it in advanced settings in steam container - it works (partially - there is known limitation around steam input which makes using steamdeck impossible with that and also perfomance drasticaly worsens when browser windows is closed)

    Hey, btw, i made a docker-mod for this here https://github.com/Joly0/docker-mods/tree/steam-remoteplay that works on my setup, not sure if it works for others aswell.
