K-Lite bug with pyqt

If I use QMediaPlayer, I'll have the problem of :DirectShowPlayerService::doRender: Unknown error 0x80040266.

If I install the K-lite, the problem can be fixed when I directly run the py file.
However, after I use Pyinstaller or Nuitka to change my .py program into .exe file, I meet the problem again: DirectShowPlayerService::doRender: Unknown error 0x80040266.

Note: If I install the LAVfilter directly, both .py and .exe file can be executed.

Is there any way to fix the K-lite? Thank you very much~

"main.exe" is currently a blacklisted name causing the filters to not load. I need to investigate if that particular name should be removed from the default blacklist. Is this the default filename used by these Python tools?

Quick solution would be to simply change the filename of the generated .exe

You can also remove it from blacklist:
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\LAV\Video\Blacklist

Got it~
The problem is solved perfectly.
"main.exe" is a default name for both Pyinstaller and Nuitka output if your .py file is 'main.py'. I recommend you to remove it from the default blacklist.

It will be removed in next version.
