Installation from Source
mt uses depends on ffmpeg's libraries, so you'll need those installed and then run:
go get github.com/mutschler/mt
go install github.com/mutschler/mt
if you'll have ffmpeg installed in a non standart directory you'll may have to use PKG_CONFIG_PATH variable like this:
LD_LIBRARY_PATH=/path/to/ffmpeg/lib/ PKG_CONFIG_PATH=/path/to//ffmpeg/lib/pkgconfig/ go build
Settings
Default Settings can be alternated via config files in JSON format, there are 3 directories in which the config can be saved:
/etc/mt/, $HOME/.mt/ and the current working directory
just create a file called mt.json in any of this locations to change the settings
to change settings on runtime you can either use the provided pflags (use mt --help for more info) or set environment Variables with the MT_ prefix:
mt --numcaps=20 myvideo.mkv will change the numcaps settings to 20 for this run only, so will MT_NUMCAPS=20 mt myvideo.mkv
since v 1.0.3-dev there is an option to save the current settings to a specified config file:
mt --save-config=/path/to/config.json
and load a custom config on runtime:
mt --config-file=/path/to/config.json
