Internal`$VideoEncodings to check available video codecs on my pc, Mathematica_11.3 gives a message:
ImportExport`RegisterFormat::noexe: Could not install QuickTime.exe.
and the output is not a list but:
I have installed QuickTime 7.7.9 from Apple, but it does not solve the problem.
I am using Windows 10 and Mathematica 11.3.
Is there anyone having the same problem?
I checked the same code with Mathematica 10.4.1 and it worked well!
Then I checked the installation directories of these two versions of Mathematica and searched for the file "QuickTime.exe". It turns out that this file exists in 10.4.1 but not in 11.3.0. I think this may causing this problem.
