NullPointerException

Hi! Here's an exception I got from couple of random files I have with me.

Sample: tv-test-10.zip

I cut the sample using this command: ffmpeg -i tv.avi -t 10 -c copy tv-test-10.avi Both the original as well as the sample are playable using apps like MX Player, VLC, mpv.

Thank you!

Yeah, it's an unsupported FOURCC (DX50) and that caused a crash. I added it and fixed it so it logs a warning instead of crashing. The clip is now playing.

That fixed it. Thanks!
