You may come across this method on the Internet more than once, however, it’s always forgotten to note that it is among the outdated ones. We are talking about using plugins for QuickTime to make it open not only MKV files but also other QuickTime non-compatible formats. One of the popular plugins is called Perian.

Nowadays, it is available for QuickTime version 7, but even if you somehow manage to download and install this version of the player on your Mac, you will face the “QuickTime player not working” issue, as this version of the video player was compiled for 32-bit OS.

Streaming MKV files to Smart TVs with Elmedia

What Is an MKV File?

MKV (stands for Matroska Video) is a multimedia container format created in 2002. A file with the .mkv extension can include audio, video, and subtitle tracks in the same file, even if those elements use a different codec. An MKV file can also store images and file metadata.

This file type is commonly used for high definition videos. However, not all media players and programs can play MKV correctly. To open it, users need to install additional applications or codecs.
