This isn't necessary (false is the default value above).

I added the #else to prevent the CommandLine switch check setting the
use_accelerated_video_decode flag back to true below.

Did you miss that there's an &= in there?

[ananta, 2012/08/13 19:52:12]

Removed the #elif OS_WIN check here. The &= expression below is enough.
