I have a Xiaomi 4k 55'' Android TV. It can't play HEVC files but most of the 4k movies I download are HEVC x265. So is there any way I can play HEVC x265 Movies & TV Shows on my TV ? And I have some other questions also-
-Is there any TV which supports HEVC Codec ?
-How people play 70-80GB Blu-Ray files ? (I am not asking about official Blu-Ray DVD , I am asking about Downloaded Blu-Ray Movies )
If you want to know what your tv is capable of, please try a film from https://jell.yfish.us/
At least you'll know what video codec and bitrate your tv can handle. My suspicion is that it can all files just fine up until 160~180 mbit if you are using a usb stick.
