Hi @KeeganRen,

I think I had similar error once and it was solved by upgrading the codecs. Unfortunately, I do not remember what versions I had and which versions solved the problem eventually.

However, this is a problem related to OpenCV and not to CLandmark, so I recommend to ask on OpenCV sites.
