On computer 2:

  1. Start Unity Hub
  2. Click the New button pulldown and select version 2019.3.2 or higher
  3. Make sure the 3D template is selected, choose a name for your project and click the Create button
  4. Bring up the Unity Asset Store Window/tab and download/import the VLC for Unity Asset. Wait for the import to complete.
  5. From the menu, select Assets -> Import Package -> Custom Package and select the VLC4Unity - rtsplooping.unitypackage file (attached)
  6. When prompted, click the Import button
  7. In the projects folder, navigate to Assets -> VLC-Unity-Windows -> Scripts and select the main scene
  8. For the VLC screen in the hierarchy, scroll down to the Use Rendering Plugin script and change the IP address in the URL to that of computer 1.
  9. Press the Play button and the videos should start streaming from computer 1. It may be necessary to disable the firewall on computer 2.

What is the current bug behavior?

The video loops several times and then the Unity editor crashes. If it doesn't crash after 5 plays, just give it more time. It will crash.

What is the expected correct behavior?

The video should continue looping and the Unity editor should not crash.

Does it work on other platforms? Does it work with the official VLC apps?

Only tested on Windows 10. Looping works using the official VLC application.
