Is Pixel Streaming broken?

Development Getting Started & Setup

It seems that Pixel Streaming is crashing Unreal, both in build applications and then playing standalone in the Editor.

It crashes with versions 4.24, 4.25, 4.26, even with applications that were built months ago and have worked fine many many times since… It crashes the moment you log in to the application with the browser (for example just localhost but also custom like localhost/streaming.htm with some html)

So far I’ve deducted that it affects only Chromium browsers, version 89+ (more or less).

More precisely:

Crashes with:

  • Edge (89.0.774.48),
  • Brave (Version 1.21.74 Chromium: 89.0.4389.72),
  • Chrome on Android (89.0.4389.86),
  • Chrome on Desktop (89.0.4389.82)

But does not crash with

  • older Chrome on Desktop (88.0.4324.190).
  • Firefox (although that’s always had performance issues).

Can anyone reproduce the issue?

I’ve just finished filing a bug report… but it would be great to hear confirmation that others have the same problem…

All my pixel streaming projects are broken with the new update (new WebRTC) fatal crash, this needs to be fixed to work with updated browsers.
Works with old Chrome version.

So I found the solution in the forums <here>

…it’s a bit of a workaround but it will get your project going if needed. Apparently the root cause is this:

The version of libwebrtc used by pixel streaming is pretty old and there’s now an incompatibility.

Still hope it will be fixed soon…
