Hello,

I would like to modify Pixel Streaming plugin to can use it while PIE session. I am just on begin of work. I copied Pixel Streaming code to can modify and when I tried to build it I get multiple LNK2019 errors about some unresolved symbols from WebRTC lib.

This one is just example:


Error LNK2019: unresolved external symbol "public: __thiscall vrpn_Tracker_OSVRHackerDevKit::vrpn_Tracker_OSVRHackerDevKit(char const *,class vrpn_Connection *)" (??0vrpn_Tracker_OSVRHackerDevKit@@QAE@PBDPAVvrpn_Connection@@@Z) referenced in function __catch$?setup_Mouse@vrpn_Generic_Server_Object@@IAEHAAPADPADPAU_iobuf@@@Z$0

I have my first milestone in made PixelStreaming while “PIE”.

What I have done:

  1. Copied PixelStreaming plugin directory from …\Engine…Plugins\Media\ to MyProjectDir\Plugins\
  2. Change all viarables describing paths in PixelStreaming.Build.cs from relative to absolute

PixelStreamingProgramsDirectory



webRTCRevisionDirectory
  1. Add "OpenSSL*"* module in “PrivateDependencyModuleNames”
  2. Delete

namespace UnrealBuildTool.Rules{

and delete last “}” in PixelStreaming.Build.cs
5. Comment all


if (GIsEditor)

statement and


return

statement in previous


if

in PixelStreamingModule.cpp in


void FPixelStreamingModule::InitStreamer()

Summary:

When I go to 127.0.0.1 in my browser (after running server and build and run my project in *DebugGame Editor mode) *I saw editor view and after clicking I had got error “PixelStreaming is not supported in editor, and should have been disabled earlier”

It is all what I have done to now. I will work more on it.

You Need Add OpenSSL to PrivateDependencyModuleNames in PixelStreaming.Build.cs，And OpenSSL error will be fixed.

And then you will find another Error about Opus，and you need add libOpus like OpenSSL.
