I've just started messing around with the latest JM 18.4 tool for a bit but after I encode a sample yuv file the video comes out poor.(Everything is on default, I did a clean compile just to make sure I didn't change anything by accident) It turns gray at some frames and looks distorted. I know this isn't the program for encoding videos but I'm using it for my project because of other factors.
I tried playing the .264 file directly with ffplay and tried using ffmpeg to convert it into an .mp4 format video, both resulted in the same quality. If anyone could enlighten my carelessness I would be greatly appreciative.
