AAC is not set by K-Lite Mega Codec Pack
Hello Guys,
I'm reporting here in hope that some Administrator from K-Lite Mega Codec Pack see this.
At the installation of K-Lite Mega Codec Pack (in Unattended mode, not tested in "normal mode", but probably the same problem happens) is that AAC is not set to FFDShow when it is marked. (It uses LAV, even when we select FFDShow in installation).
It happens because the key HKLM\Software\LAV\Audio\Formats (In 64-bit OSes: HKLM\Software\Wow6432Node\LAV\Audio\Formats) the value aac (REG_DWORD) is set as "1". It should be "0" when FFDShow is selected by default in installation.
As an Workaround, I added the following lines into kclp_mega_unnatended.bat:
It detects if OS is 32 or 64-bit, then edit aac key to "0" to use FFDShow to this format.
It also overrides HKCU value from actual user.
It could edit every user file from computer using https://github.com/MicksMix/RegUpdateAllUsers/blob/master/RegUpdateAllHkcuHkcr
But I did not developed it any further. It is an workaround and I do not pretend use it in a production environment.
Hopping anyone could reproduce this and apply the required fix at the K-Lite Mega Codec Pack installation logic.
Thanks.

Re: AAC is not set by K-Lite Mega Codec Pack
ffdshow has a higher filter merit than LAV. So if a format is enabled in ffdshow it will be used even when it also is enabled in LAV. It is not a bug that AAC is enabled in LAV. It is done intentionally.

I didn't know that, thanks for the info!
But the problem is that LAV is being used EVEN when I set it to explicity set it to FFDshow. Only when I disable it in LAV or disable LAV Audio completely (unregister it through Codec Tweak interface) it uses FFDshow filter.
The problem is that FFDshow is not being set to aac in installation when this option is marked (it uses LAV by default, I want to use ffdshow for it). It is using LAV when it should not!

Are you using Windows Media Player? In that case:
Codec Tweak Tool > Preferred Decoders
