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.
My OS is Ubuntu 14.04 LTS, OpenCV 2.4.11, CMake 3.5 ./video_input ./ flandmark_model.xml cam 0 10:01:06 It's OK. But when I want save the result. ./video_input ./ flandmark_model.xml cam 0 output.avi 10:02:01 HIGHGUI ERROR: V4L2: Unable to get property(5) - Invalid argument
