Compress Bad Quality

[devluckman]

I followed the sample project for query compress video, but the video result is bad, I want to change the query setup so that the video can be better, but I don't understand the query setup, is there any documentation for the query or example of query setup so that the video is better

I used the query from the sample project in Class FFmpegQueryExtension

fun compressor(inputVideo: String, width: Int?, height: Int?, outputVideo: String): Array<String> {
        Common.getFrameRate(inputVideo)
        val inputs: ArrayList<String> = ArrayList()
        inputs.apply {
            add("-y")
            add("-i")
            add(inputVideo)
            add("-s")
            add("${width}x${height}")
            add("-r")
            add("${if (FRAME_RATE >= 10) FRAME_RATE - 5 else FRAME_RATE}")
            add("-vcodec")
            add("mpeg4")
            add("-b:v")
            add("150k")
            add("-b:a")
            add("48000")
            add("-ac")
            add("2")
            add("-ar")
            add("22050")
            add("-preset")
            add("ultrafast")
            add(outputVideo)
        }
        return inputs.toArray(arrayOfNulls<String>(inputs.size))
    }

Thanks
