Why has Gallery changed so you can not choose which video player to open which video. (Samsung S5)

AC Question

I have loads of videos all of which can only run with certain players. So now if I want to play them from gallery, I have to keep changing the player what a load of rubbish.
Why do they keep doing stuff like this? Last time they made it so you couldn't turn off the volume and vibrate. I mean do these people every ask anybody before just jumping in a destroying a perfectly good app.
There is too much time spent on pushing unwanted adverts and bloatware and not enough time spent on getting the fundamentals right. If they carry on like this I am going to bite the bullet and move over to apple. I am really getting fed up with all this. You pay hundreds of pounds for these phones and then they **** on you without even the courtesy of calling it rain.
Any ideas about the gallery would be welcome.
If anybody is using MX Player mine has started playing the same file in gallery no matter which one I click on, what is that all about ?
