A couple of years I used Zoom Player. I had th pro and liked it, because you could indeed zoom in the scene while movie was running.
I do not know why I stopped using it.
YOu have done a good research, because VLC player an Gomplayer are the best players at the moment.
Both are free and both can play all file types, without having to download other codec packs. like K-Lite Codec Pack
I use the Gomplayer, because I found it easier to use.
