I put it on the media gallery, then try to open from the media player and say "invalid format" (not exactly like that but that's basically the error).

If i looked in the folder then try to open, say exactly the same.

I put it first on a folder in my sd card and say the same error.

I guess i doesn`t matter the quality of the video i put (i have it on 480p) or that`s the problem?
