I have a video in MKV format that I wanted to convert to MP4, so I used ffmpeg to convert it. The command I used was pretty simple:
ffmpeg -i <path_and_name_of_file>.mkv <path_and_name_of_file>.mp4
I don't really know how to use ffmpeg and since this is probably the only time I plan to use it I looked up how to do it online and it said I can just use that simple command if all I'm doing is changing the file format.
So I did that, and it did the process like normal (it took about 10 hours because it's a 1080p 3+ hours video) but when I tried playing the file it didn't work. I tried Movies & TV and Windows Media Player and they both open the file and show how long it is, but when I hit play nothing happens, not even an error message. But it did play when opening it with VLC Media Player or Chrome.
The problem is, both Movies & TV and WMP play the original MKV file just fine, so I must have done something wrong with FFmpeg. Is it that I have to add more stuff to the command or something?
Update: Sorry it took me so long to come back to this. I'm guessing this bit is what grawity was asking for. The original MKV video:
