Please share knowledge about how to call that will run the command like
String cmd = "-y -i " + inputVideoPath
+ " -crf 22 -preset fast -c:a aac -c:v libx264 -movflags +faststart"
+ " -f mp4 -brand mp42 "
+ outputVideoPath ;

First compile ffmpeg with enable programms, and after that you will get ffmpeg executable along with .so libraries put them in your jnilibs folder and at appstartup copy executable to your apps cache directory or private files directory Open the executable file like this function

 private fun extractFFmpeg(): File {
    val outFile = File(filesDir, "ffmpeg")
    if (!outFile.exists()) {
        assets.open("ffmpeg").use { input ->
            FileOutputStream(outFile).use { output ->
                input.copyTo(output)
            }
        }
        outFile.setExecutable(true)
    }
    return outFile
}

And then you can use it like this to execute your command.

val ffmpegPath = extractFFmpeg().absolutePath

val process = Runtime.getRuntime().exec(arrayOf(
    ffmpegPath,
    "-i", "/sdcard/in.mp4",
    "/sdcard/out.mp4"
))

val output = process.inputStream.bufferedReader().readText()
val error = process.errorStream.bufferedReader().readText()
val exitCode = process.waitFor()
