Presumably most people are quite familiar with the video filetype with .flv extension. As a Flash video format, in the past two decade, it can be said to have been in the limelight for a while and even once used as a de-facto standard for many web-based video streaming websites. However, since Adobe has officially ended support for Flash on December 31, 2020, the use of FLV format is doomed to decline.
Instead, Matroska is a free and open container format that can encapsulate an unlimited number of video, audio and subtitle tracks in one .mkv file, and is commonly accepted by a large range of media players, editors, game consoles and other devices. Therefore, many people are increasingly inclined to convert FLV to MKV. No worries, that's the main reason why I've compiled this guide below.
