[MX Player] CHEchenyu:
I am using HTC E8 and as snapdragon 801 supports HEVC playback on HW decoder, it is perfectly playable for mp4 videos. However, if the same video is encoded into a MKV format with all the encoding settings the same what so ever or just remuxed into a MKV, mx player just says HW decoder is not supported, forced to use the sluggish SW decoder. Below are the media info for the videos to refer:

This the mp4 version, which is playable through the HW decoder smoothly.
