FFmpeg Kit KMP

This is a Kotlin Multiplatform library project targeting Android, Desktop (JVM).

I can't test the macOS and iOS version. Therefore, there is no iOS release. PRs are welcome.

iOS support is planned, but not soon.

NOTICE: This version is subject to GPL-3.0, namely bundle-video_hw-shared-gpl-release.

commonMain.dependencies {
    implementation("io.github.sor2171:ffmpeg-kit-kmp:0.11.4")
}

If you want to replace the FFmpeg libraries, they are located in shared/src/jvmMain/resources / ffmpeg-aar-wrapper/libs.

./gradlew :shared:assemble

The built artifacts will be in shared/build/libs / shared/build/outputs/aar.

To run an FFmpeg command:

fun testFFmpegCreateColorBar() {
    val output = FFmpegRunner.execute(
        "-re",
        "-f lavfi",
        "-i testsrc=duration=10:size=1920x1080:rate=60",
        "-f null -"
    )
    println(output)
}

To run an FFprobe command:

fun ffprobe() {
    val json = FFmpegRunner.ffprobe(
        "-v quiet",
        "-print_format json",
        "-show_format",
        "-show_streams",
        "/path/to/your/video"
    )
    println(json)
}
