Check whether Dash still works, and fix it if it doesn't.

Subject says all.
Needed for messy.

[jackjansen]

There are issues getting the SFU started from the orchestrator. Issue created.

On the Mac, the idea of using the config variable SIGNALS_SMD_PATH no longer works (because it's going to be in Library/ under some unknown pathname. Need to rethink.

[jackjansen]

After manually fixing the SIGNALS_SMD_PATH the uploader still doesn't work. The Unity log file has the following error:

And, indeed, on the Mac there doesn't seem to be a libgpac. Possibly never put into VRTNativeLibraries.

[jackjansen]

To do: check whether there's still a copy somewhere in VR2GNativeLibraries

[jackjansen]

It's not in the repo, and it looks like it's never been in the repo. But there seems to be a full copy of the MS stuff on flauwte in
/Volumes/FlauwteSSD/opt/msprod/sysroot/osx.

(For reference the orchestrator issue is cwi-dis/vr2gather-orchestrator-v2#30)

[jackjansen]

Dash uploader does not work on Windows. When bin2dash.so it tries to load MPEG_DASH.smd, which is its extension module to do mpeg-dash, it fails. Possibly a %PATH% issue.

The file exists, and inspecting the file with DependenciesGui does not show any missing references. But some of those references are in the same directory as where mpeg_dash.smd itself is, so maybe that is the problem?

Here is the Editor log output from a run under the VS debugger. You can see that it tries to load the .smd and then immedeately unloads it again.

On Mac-Intel the dash uploader also doesn't work, but this is a different problem: it can't even load bin2dash itself.

It doesn't appear to look in that nl.cwi.dis.vr2gather.nativelibraries@cd233771f0/Runtime/Plugins/Mac directory.
