The HD button does not work with local video.
I've tried using the youtube video and it works fine.

Dear customer,

Which upload type have you selected when uploading the video?

I've select urlHD.
I attach a .png file.
I've try with a 1280x720 video format.
The player check the hd format of file first ti play?
