-map 0:a:1 – will put the second audio stream of the first input file as first audio stream.

-map 0:v:0 – will put the first video stream of the first input file as first video stream.

The ‘map’ parameters will have to be used as following: If you have a more complex stream situation in your input file you can also use the alternative syntax to achieve the same. -disposition:a:0 0 – will erase any previous disposition settings (in this example removing default and forced setting).-disposition:a:0 default – will define the first audio stream as default.-map 0:m:language:ger – will put the German stream as second audio stream.-map 0:m:language:eng – will put the English stream as first audio stream.-c copy – will just copy the streams without re-encoding.mkv - c copy - map 0 : v : 0 - map 0 : a : 1 - map 0 : a : 0 output. To do that we can use the following command:įfmpeg - i input. Stream 2: audio stream, German language.Stream 1: audio stream, English language, default stream.In the above example file we only have one input file, and therefore the first number will always be 0. The second number y represents the stream within the input file. The first number x represents the number of the input file. Note on the enumartion ‘#x:y’: Counting starts with 0. If you defined English as your preferred audio language in your video player, with this example file the player would play the German language nevertheless. Stream 2: audio stream, English languageĪ forced audio stream will override the settings in your video player.Stream 1: audio stream, German language, set as default audio stream, forced audio stream.

The multimedia file contains three streams (see highlighted lines in yellow): In this example you can see the following. _STATISTICS_TAGS - eng : BPS DURATION NUMBER_OF_FRAMES NUMBER_OF_BYTES _STATISTICS_TAGS-eng: BPS DURATION NUMBER_OF_FRAMES NUMBER_OF_BYTES
