Nexus 7 2nd tablet Users always encounter this or that problem when they play MKV videos, though the media players they use promised to support MKV videos playback, but, the process wasn’t smooth. A series of problems have appeared. Such as no audio, no video, audio and video are not synchronized, or even an error message pop up, said that “unsupported media files”.
Why would this be? MKV is short for Matroska Video format. Matroska is a container format file that stores multiple streams (video, audio and subtitles). The streams are likely compressed and have been produced with an encoder. In order to play these streams a codec is required. Codec, as a word is an abbreviation of Coder / Decoder. The video stream located in the MKV file has been “coded” by the source and now it must be “decoded” by the end user who wishes to play it. For this situation, we can summarize Google Nexus 7 2 built-in media player lacks powerful decoder to decode all the MKV videos, even if the additional downloaded android players.
