Does this show anything? And, I did try webm and it worked fine. IDK which is the smaller file, webm or mp4. I usually watch this stuff with vlc on windows or an OS using vlc.

This is still your original problem which I explained to you then. That is a hardware encoder and you don't have whatever hardware it's looking for. You have to use "-vcodec" to select a different encoder.
Try "-vcodec libopenh264" since you're still using ffmpeg from the Fedora repo.
