How to convert tencent video download format to mp3 format?

First, qlv is a special format for tencent video, other players can't decode and play it

Second, qlv is video, mp3 is audio, so we need to convert qlv to a common video decoder that can accept it, such as mp4

Third, to convert qlv to mp4 or any other decodable formats, you can use editing software (pr, ed, acoustic video, fnc) to separate the output video and audio. But there is a simpler way to convert audio separately in a transcoder, you can download and use beaver, format factory, or magic shadow transcoder
