How to change the default audio track of an MKV file

audiomatroskavideo

I have an MKV video file that has two audio tracks, a Hindi-language track and an English-language track. I guess the Hindi track is set as the default track. I have a video player that doesn't allow you to select different audio tracks, so it only plays the Hindi one.

So my question is, how can I change the default audio track to the English one? I found this tool that allows you to do it, but it's a command-line tool. Are there any GUI tools that achieve the same thing?

its not only CLI. here you can download GUI: https://www.fosshub.com/MKVToolNix.html
and this is how you use it:

select tracks
set desired tracks as deafult
mux it all

btw, you should consider to have new media player: https://potplayer.daum.net/

stream selection

Default stream selection behavior is to select one stream type per input. For example, as in your input, if it contains two audio streams, then only the stream with the most number of channels will be selected.

You can tell ffmpeg to include all streams with the -map option.

Because the -map option begins counting at 0, the 0 in this example refers to the first input (input.avi: your only input in this case). If you had additional inputs then -map 1 would refer to the second input.

set language metadata

To set the language of the first and second audio streams use the -metadata option with stream specifiers:

ffmpeg -i input.avi -map 0 -codec copy -metadata:s:a:0 language=eng -metadata:s:a:1 language=rus output.avi

See the documentation for more info.
