Not streaming on macos

[RWOverdijk]

I've installed obs on mac os using this release but it won't start streaming.

It says:

Starting the output failed. Please check the log for details.

Note: If you are using the NVENC or AMD encoders, make sure your video drivers are up to date.

I've changed the encoders for streaming and recording but it had no effect.

I've also checked the logs:

How can I get this to work, and keep it working in the future? Updating OBS seems to remove the agora plugin so I don't know what the best approach is.

[plutoless]

i will take a look

@plutoless Mac plugin for OBS is not working for me on multiple devices. Can you guide what should be the approach to run it until the permanent fix will be available.

[RWOverdijk]

fwiw I am now using standard obs and virtual webcam. That way I can use a webclient to stream.

Ideally this project would offer an obs plugin, that way it's easier to update and work with. But that's just my opinion 😄

[Reinhartdelille]

I second that ! For our live streams a tool like OBS or VMIX is just too powerful to ignore and to much hussle to build ourselves, either directly from SDK or by compiling the Agora OBS Plugin. BTW @RWOverdijk do you use VCable to pipe the audio in standard OBS?

[plutoless]

we are planning to offer a windows plugin but macos is still planning.

[Reinhartdelille]

Amazing, Volunteering to test extensively here! Will we be able to set audio and video profile parameters for the agora engine? That will be very important for us.

[RWOverdijk]

@Reinhartdelille yes, I am. Meanwhile I'm working on a plugin to replace this project with in my workflow. Slowly. 😅
