When come to media player, there are tvbox, media player and bluray player.

The most popular bluray players is oppo, which is using MTK solution. It can play most of the file format, but may incompatible with some movie files (MKV, depend on the encoding). This is meant for playback discs.

The very popular true media players are Dune 4k and Popcorn A500 Pro (this was developed in Penang). They are provided by Sigma solution. They can play most of the file format including MKV and encoding. It can even play the becoming popular H265 encoding.

Himedia, xiaomi blah blah blah are android tvbox. They are ARM solution running android, their purpose is to use IPTV to stream movies/tv to the box and normally use H264 encoding.

Technically among these, firmware based like MTK and Sigma offer the best PQ, But some do like android based TV box quality.

You have 2 options for HEVC, VLC on your PC or Dune 4k or Popcore a500.

Are you saying that those himedia are technological advanced than the hardware decoder dune and popcorn?

All android boxes SQ and PQ not on par than those bd player and media players.
