Sure, you can do that, but at that point you're already on the other side of
the airtight hatchway. If you have control of the player, you don't need
detours at all; you can just read the data directly from the source.

Subject: [wdmaudiodev] Capturing protected audio using MS Detours
I just did a POC which captures audio data using MS detours. All I did was to
detour GetBuffer() and ReleaseBuffer() calls and dump audio data in a file. I
have tested it out and it seem to be working fine.
I was wondering how this POC will behave with protected content (HBR audio data
usually available with BDs). Will it be able to capture protected data?
I have no intention of capturing protected content. It's just that I don't see
anything preventing someone from ripping protected audio content using MS
detours and was wondering if Microsoft puts in some sort of checks to prevent
it. (e.g. restriction on protected audio playback if detour.dll is loaded in
process).
Thanks and regards,
Ambrish
