It depends. If video editing was simple, it wouldn't require complex
tools. ;-)

In your case, my guess is that ffmpeg is unable to mux all the data
streams. If you use "map 0 -sn", ffmpeg should omit them.

They may or may not carry usefuk information for you, but if you
yourself don't knwo what they're good for, then just drop them.

Generic is difficult with ungeneric input.

See my guess above.

Do read all of your warnings please. (I'm too lazy to check:
"-profile:v" should do the trick for you.)
