Empty service name in consul info!

emassey · 2018-05-18 14:36:12 UTC

In my ue4 project, I’m getting an error where the streamer is not able to start. Do you know what I need to do to fix this?

Thank you!

Eugene

These are the errors in the web console:

Failed to load http://127.0.0.1:49630/streams/program.mp4: No ‘Access-Control-Allow-Origin’ header is present on the requested resource. Origin ‘http://127.0.0.1:39073’ is therefore not allowed access. The response had HTTP status code 404. If an opaque response serves your needs, set the request’s mode to ‘no-cors’ to fetch the resource with CORS disabled.

Hi Eugene,

I’m checking with the team and will get back to you shortly.

Thanks,
Sophie

emassey · 2018-05-18 14:58:28 UTC

Great. Thank you!

From the cluster ui, I can see that the services and web are running but the game seems to not be registering. It mainly stays in the “starting” state and occasionally goes into running for just a couple seconds. Maybe this is an issue with not pointing to the game correctly? I’m trying to run from the editor and I’m setting my path in the game.hcl to the UE4Editor.exe.

slibert · 2018-05-18 15:09:55 UTC

Hi Eugene,

Maybe your executable path is not set correctly.

In your game.hcl, you should have:

path = “{{env UTROOT | js}}\\Engine\\Binaries\\Win64\\UE4Editor.exe”

where UTROOT = C:\Workspace\UT4\UnrealTournament for example.

like:

path = "C:\\Workspace\\UT4\\UnrealTournament\\Engine\\Binaries\\Win64\\UE4Editor.exe"

emassey · 2018-05-18 15:17:43 UTC

Yes, the path seems to be set up correctly. I tested it by putting in some bad values and when I do that, the game doesn’t register at all - It shows up as dead in the cluster UI.

emassey · 2018-05-18 15:19:44 UTC

I’ll try hard-coding the whole path as you suggest and see if that helps!

emassey · 2018-05-18 15:22:19 UTC

Unfortunately, after trying it with the hard-coded path, I get the same results.

slibert · 2018-05-18 15:28:14 UTC

Ok,

As you start from the editor, you should have some log in the Output.log window in UE4 Editor.
Go to Menu Window > Developer Tools > Output.log to show the logs.

You should have logs like this one:

If I try running it a second time, I get this and can’t proceed:

slibert · 2018-05-18 16:10:13 UTC

Ok, it seems that there is an error:

LogOutputDevice: Error: Ensure condition failed: Component->HasBegunPlay() [File:C:\GitHub\Greed\UnrealEngine\Engine\Source\Runtime\Engine\Private\Actor.cpp] [Line: 3141]

Where did you Initialize the GenvidSessionManager?

Do you have a PlayerController with GenvidStreams and/or GenvidEvents and/or Genvid Commands components like this?

emassey · 2018-05-18 16:16:42 UTC

I can look into that error and see what is going on.

I have the player controller set up with the three genvid components.

I’m trying to initialize the GenvidSessionManager from the game mode rather than the gameinstance. Could that be causing issues?

slibert · 2018-05-18 16:31:40 UTC

Yes, it can cause some issues because the GameMode is only available on the server part.
Genvid is only needed on the client part.

The plugin has some code that checks if you’re running on the client or server side.

GameInstance is a good place to place GenvidSessionManager. (client/server agnostic)
GameState should work too.

emassey · 2018-05-18 19:01:10 UTC

I fixed the error we were getting in actor.cpp and moved the initialization of the GenvidSessionManager into the gamestate. I’m still getting the same set of errors and behaviors. Anything else I can try?

Thanks,
Eugene

In case it is relevant, I am getting some genvid errors when I stop the game related to destroying the streams. It looks like the streams never get created possibly?

Maybe this issue then leads to the error related to startvideocapture on subsequent attempts to start the game.

It’s really strange.
You have several call with the same Stream Id “MyStream”

LogGenvid: Error: DestroyStream(MyStream) failed: UnknownError (3).

Do you have only one game instance?
Do you run in hybrid mode (client/server) or in client / server mode?

emassey · 2018-05-18 22:14:12 UTC

After looking into what was going on, we found a couple things leading to the issues but the main problem was the order in which things were loading. Ended up using the game instance to initialize the session manager and loading the components on the game state and everything worked. Thanks for all the help with this today!
