lsl_continuous_resolver failing to find streams that resolve_streams could find.

[cboulay]

After debugging an issue in Slack with users of LSL4Unity, we figured out that the lsl_continuous_resolver was failing to find a marker stream that was easily found with resolve_streams. This only happened when the resolver was trying to find a stream from a different computer on the network and there was no issue when everything was on a local computer.

Edit - After further testing, here's a summary of the findings.

Outlets:

• Macbook running python -m pylsl.examples.SendData
• Win64 running python -m pylsl.examples.SendData , modified to change stream name, type, and id.
• Win64 game in Unity editor - stream out object position
• or Win64 game build

Results:

• Win Python can resolve all outlets whether using resolve_stream() or ContinuousResolver
• Mac Python results are very strange. It always finds the mac-originating stream.
  • resolve_stream()
    • Finds the win python stream, but only if game is running in build (running via Editor is blocking unrelated stream!?)
    • Finds the Unity stream only if it is running from the build
  • ContinuousResolver
    • Always sees the mac python and win python stream, even if game is running in Unity Editor (win python stream not blocked)
    • Finds the Unity stream only if it is running from the build
• Game as inlet...
  • resolve_stream()
    • Finds the Win python stream always (Editor and build)
    • Finds the Mac python stream, but only in build, not from Editor
      • There's some weird interaction where the game will crash if ContinuousResolver isn't created, even if it is never used and ultimately the stream is found with resolve_stream. However, if the win python data stream is stopped first then ContinuousResolver isn't needed for resolve_stream to work. What?!
  • ContinuousResolver
    • Finds the Win python stream always (Editor and game build)
    • Never finds the Mac stream. Not in Editor, not in game build.

Hello! Im trying to run the LSL tutorial with the cube but when im writting the LSLInput script im getting this error: Assets\LSLInput.cs(22,27): error CS0234: The type or namespace name 'resolve_stream' does not exist in the namespace 'LSL' (are you missing an assembly reference?). Am i missing something? Thanks in advance!

Hi @gprapas , this is not the correct place. I assume you're referring to Unity? Please check https://github.com/labstreaminglayer/LSL4Unity
