mkvtoolnix-wrapper

An easy to use light kotlin-jvm wrapper for most common mkvmerge and mkvpropedit CLI commands.

The library is published on maven central:

compile 'com.github.mmauro94:mkvtoolnix-wrapper:1.0.0'

WARNING This library is not feature complete: there are quite a few advanced options that are not currently supported. You can achieve them adding custom args to the command.

Usage

To identify a file:

MkvToolnix.identify(File("input.mkv"))

To edit properties:

MkvPropEditCommand(File("input.mkv"))
    .editTrackPropertiesByNumber(2) {
        set("prop", "val")
        delete("anotherprop")
    }
    .executeAndPrint()

To merge files:

MkvMergeCommand(File("output.mkv"))
    .globalOptions { 
        title = "Title"
    }
    .addInputFile(File("inputA.mkv")) {
        videoTracks.include {
            addById(0)
        }
    }
    .addInputFile(File("inputB.mkv")) {
        videoTracks.excludeAll()
        subtitleTracks.excludeAll()
    }
    .executeAndPrint()

You can find more complete examples here.

The commands will use mkvmerge and mkvpropedit from the PATH environment. To change that, you can set the location of the binaries with:

//Set custom path
MkvToolnix.mkvToolnixPath = File("custom/path/to/binaries")

//Reset to using PATH environment
MkvToolnix.mkvToolnixPath = null

Methods and classes are thoroughly documented and linked to official doc when possible, so you can read more there.
