I’m having the same issue - my understaning is that it should work with some more commands (found in <link>)
Blockquote
PixelStreaming.Capturer.UseBackBufferSize false
PixelStreaming.WebRTC.DisableResolutionChange false
Then, when you want to update the resolution later, use
PixelStreaming.Capturer.CaptureSize 1920x1080
And, if you also want the render resolution to match, use
render.SetRes 1920x1080
as well.
However… this solution appears to be broken as of 4.27.1. Right now I’m making a bug report for this. Hopefully it’s fixable soon because Pixel Streaming is losing a lot of appeal if it’s impossible to change resolution.
