[FFmpeg-user] How can I Convert mpeg-dash files to mp4/mkv using FFMPEG?

[Saif Ullah]

Recently I tried downloading a video file via a program called "video cache
view", it created two video files instead of one numbered as
mpegdashtmp1.mp4 which are i guess in some mpeg-dash format. I searched
about it and came to know that out of these two files one should contain
the audio and the other will be the video part. How can I convert those
files to mp4/mkv via FFMPEG.
