Hey @fabiohfernandes,
I’ve also seen that video. It’s completely AI generated and if you put “What’s the difference between Pixel Streaming 1 and 2” into ChatGPT you get almost the exact script for that video…
The PixelStreamingInfra repo contains a migration guide for users wanting to move from Pixel Streaming 1 to 2 as well as the actual differences between the two versions.
You’re correct in stating that the official Matchmaker provided by Epic has been discontinued with users now expected to implement their own if they’re wanting to use one. Ideally, the PixelStreamingInfra is backwards compatible so using the 5.4 infra branch (that contains the matchmaker) with UE5.5 and PixelStreaming2 should still work.
Have you got any logs that could show what’s going on?
