# How to merge video stream and two Stereo audio streams in 5.1 with a terminal command?

(Asked by: username_0 on 2013-09-05)

What I want as result: a video with the English stream on the front lineout of my soundcard and a German audio stream on the rear lineout of my soundcard.

So far, I extracted the streams with:

`mkvextract tracks video.mkv 1:video.h264 2:audio.ac3`

...to get the single streams from an .mkv.

Is there a way to merge the two audio streams to the video the way I want to have it?

**Tags:** video, mkv

That depends on your video file format and possibly if you have a surround encoder. Some file formats provide multiple audio channels that can be configured for different speakers, others rely on a Dolby encoding or similar to provide the speaker information in one audio stream.

Either use a file format that supports multiple independent audio tracks per speaker or use a Dolby (or some other system like MPEG Surround) surround encoder to encode the audio in to a single Dolby (or similar) stream that can be processed by a Dolby (or similar) receiver.
