Not working on Windows Docker

[My-Name-Is-Adam]

Hi, new to Docker, so maybe just me not setting this up properly.

So I've installed Docker on my Windows 10 device.

In cmd, I ran the following two commands separately:

docker pull erdnaxeli/castblock:latest
docker run --rm --network host erdnaxeli/castblock

When casting from the YouTube app to my phone, the sponsors still show.
Same when casting from the Android app.

Command prompt is showing the following:
C:\Users\adam_>docker run --rm --network host erdnaxeli/castblock
2021-08-15T05:50:46.211781Z INFO - castblock.chromecast: Found go-chromecast at /usr/bin/go-chromecast.
2021-08-15T05:50:46.211838Z INFO - castblock.chromecast: Starting the go-chromecast server.
2021-08-15T05:50:46.716203Z INFO - castblock.chromecast: The go-chromecast server is up

Any ideas on how to get this to work, please? SponsorBlock works fine in the browser but doesn't skip the sponsored segments on Chromecast, which I thought this should be doing.

Thank you.

To add I have allowed the port just in case, and also ran it via an elevated command prompt window but it didn't solve it.

I ran it with the --debug flag and I'm not seeing any errors.

Hi, sorry for the wait.

I don't know how docker works on windows, but I bet the "host" network is not available. As the windows kernel does not support docker, it must run in a vm, and I guess the network always goes through a NAT. Sadly this makes go-chromecast (the tools castblock use to talk to the chromecast) unable to work as it needs to be able to broadcast packets on the same network as the chromecast :/

[erdnaxeli]

Yeah :/. From the official documentation : https://docs.docker.com/network/host/

The host networking driver only works on Linux hosts, and is not supported on Docker Desktop for Mac, Docker Desktop for Windows, or Docker EE for Windows Server.

You would need to run go-chromecast and castblock on windows directly. Sadly Crystal (the language used to write this project) does not currently support windows : crystal-lang/crystal#5430.

I will keep this issue opened, if anybody also wants a windows support please put a thumb up on the first message.

Hey, thank you for letting me know.

That's such a shame. I've had a look at not really sure how to use go-chromecast and castblock on Windows without the tool. I can't really find any decent documentation. If you're able to offer any advice I would really appreciate it. Thank you very much. :)

Not to sidetrack but this project doesn't work on Windows or Mac either? It would be nice to have this mentioned in docs that it doesn't work on standard operating systems as I've spent a few hours trying to get it to work. :(

@dustinbolton It looks like crystal works on mac, so I don't see why it wouldn't. The other component is go-chromecast which, written in go, should compile on mac just fine.

As for windows, would running the castblock / go-chromecast binaries in WSL work? It seems like the major limitation here is just if you're set on using Docker on windows/mac.

[erdnaxeli]

You need to have access to the same LAN as the chromecast in order to be able to listen for the broadcast packets emitted by it. The network inside WSL is not bridged with the one of the host, instead it seems to uses a NAT, so I don't think it will work either.

[erdnaxeli]

The windows support by Crystal has increased, we could try to compile castblock for windows (and run it natively without Docker).

Bumping to show my interest and seeing if there have been any updates on this 🌿
