Installation

Step 1 — Add JitPack

dependencyResolutionManagement {
    repositories {
        maven { url "https://jitpack.io" }
    }
}

Step 2 — Add Dependency

// Version 1.12: Media only (audio/video features)
implementation("com.github.media6666:FFmpeg:1.16")

// Version 1.14: Media + AI Sound features
implementation("com.github.media6666:FFmpeg:1.14")

Step 3 — Init FFmpeg

FFmpegMedia.getInstance().initLib { loaded ->
    Log.e("LIB loaded", "$loaded")
}

Usage

1. FFmpegMedia.getInstance().setCancelFlag(0) // ← Reset once before running FFmpeg

2. FFmpegMedia.getInstance().run(
    command = commandArray,
    durationTotal = 10000L,
    progressCallBack = progressCallBack
)

3. FFmpegMedia.getInstance().setCancelFlag() // when destroy Activity or Done task

Video → MP3

val cmd = "-i ${videoPath} -vn -ar 44100 -ac 2 -b:a 192k ${outputPath}"
val commandArray = cmd.split(" ").toTypedArray()
FFmpegMedia.getInstance().run(
    command = commandArray,
    durationTotal = 10,
    progressCallBack = progressCallBack
)

Audio Cutter

val cmd = "-i $input -ss 00:00:05 -to 00:00:12 -c copy $output"
val commandArray = cmd.split(" ").toTypedArray()
FFmpegMedia.getInstance().run(
    command = commandArray,
    durationTotal = 10,
    progressCallBack = progressCallBack
)

Merge 2 Audio Files

val cmd = "-i $input1 -i $input2 -filter_complex amix=inputs=2:duration=longest $output"
val commandArray = cmd.split(" ").toTypedArray()
FFmpegMedia.getInstance().run(
    command = commandArray,
    durationTotal = 10,
    progressCallBack = progressCallBack
)

Change Speed / Volume

val cmd = "-i $input -filter:a "atempo=1.25,volume=1.5" $output"
val commandArray = cmd.split(" ").toTypedArray()
FFmpegMedia.getInstance().run(
    command = commandArray,
    durationTotal = 10,
    progressCallBack = progressCallBack
)
