Please fix this error!

I love this app, but Ive noticed that I cannot crop any of my videos anymore because it says it "Cannot Decode". I use an .MP4 file, which had always worked before and should work, so I dont know why it doesnt work anymore. Please fix this issue soon! I cannot use this app anymore and it makes me really annoyed.
