Where can I grab the Qt MSVC package for Visual Studio 2019, in order to build OBS from source, as mentioned in the Wiki:

"Requirements for building OBS on Windows

I'm not seeing a download for this on the Qt site.

Thanks,

Thanks! I finally did see that (those) links buried at the bottom of the open source page late last night.

Downloading now. Do I assume there is a folder of DLLs, Libs, etc., that I drop into a folder for the OBS build (i.e., QTDIR=). Hoping there is a readme.... ;)

I'm confused. This installer installs the full QT development environment. In order to build OBS, I assume I need to link with specific libraries and DLLs from QT - but where do these get installed? Which ones do I need to include?

There MUST be some documentation on this somewhere... I've wasted a full day trying to figure out how to get hold of QT components so I can build OBS (need this for a project i'm working on).

Can someone please provide direction on this? Why is there not a package of the DLLs & Libs from QT for this purpose????????

Per the text you quoted in your first post:

> Grab the MSVC package for your version of Visual Studio

Like so:

Then you point to it in CMake like so:

OBS does the rest (it turns into this)

Thanks again. Got it basically working today - but used a set of binaries (open source) downloaded from Qt's site - I was having trouble finding the MSVC package... but I like this approach a bit better. Will look into this.

Compile results in just one error: 'iscursorcaptureenabled': is not a member of 'winrt::windows::graphics::capture::graphicscapturesession

Looks like a Windows SDK mismatch.... (?) investigating...

Yep that required 19041 SDK. Once installed you will need to reboot and it should be auto-detected by CMake.

Thanks - with this, everything is building beautifully. However...

While I can run the generated Obs64.exe from ~\obs-studio\build\rundir\Debug\bin\64bit from Exporer and the command line, it doesn't run from the Visual Studio 2019 debugger. I get this:

==== Startup complete ===============================================
Output ID 'ffmpeg_muxer' not found
Failed to create output 'adv_file_output'!
output 'adv_file_output' (ffmpeg_muxer) created

...

Any ideas on what I might be missing?
