macOS 64 bit QuickTime plugin?

[ArtOfWarfare]

I have a Python application that can't display a video inside a QTWebView. In the error log I'm getting this message:

Python[38725:1307] Error loading /Library/Internet Plug-Ins/QuickTime Plugin.plugin/Contents/MacOS/QuickTime Plugin:  dlopen(/Library/Internet Plug-Ins/QuickTime Plugin.plugin/Contents/MacOS/QuickTime Plugin, 265): no suitable image found.  Did find:
	/Library/Internet Plug-Ins/QuickTime Plugin.plugin/Contents/MacOS/QuickTime Plugin: mach-o, but wrong architecture

When I checked the architecture of the QuickTime Plugin I found that it was only 32 bit.

I looked into it and QuickTime X was released a few years ago which was 64 bit... has a corresponding 64 bit QuickTime plugin simply never been released or am I running a dated plugin? (I checked the software update section of the MAS and it didn't say any updates were available...)

QTKit on 64-bit launches a subprocess that is 32-bits then acts as a proxy between the process and the app to decode codecs that QTKit (or CoreAudio for audio codecs) doesn't do natively.

However, I wouldn't be surprised if Safari linked directly to QTKit instead of using the QuickTime Internet plugin, or ran the plugin in a similar vein as what QTKit does.
