Video Compression Using Sili Compressor in Android Kotlin

var des="/storage/emulated/0/Android/data/"
var newpath= SiliCompressor.with(this).compressVideo(filepath,"newmovies")
I'm compressing a video of 14 mb and it reduces to just 324kb. Video compression using sili compressor in Android kotlin reduces video quality too much.
If I do compression with custom resolution:
var newpath= SiliCompressor.with(this).compressVideo(filepath,"newmovies",1080,1920,30)
it decreases video quality too much.
How can I compress a video in android other than through FFMEG?
I have try media codec but it didn't work.
here is the image of code
public String compressVideo(String videoFilePath, String destinationDir, int outWidth, int outHeight, int bitrate) throws URISyntaxException {

MediaCodec Video Create Too Fast

I am trying to create Video frames camera frames using Camera1.Even when I take long Video from camera Video Plays it Too Fast.I tried changing bitrates and frame rates.
image byte[] from camera frames is being queued and fed to this class so that we could create video from bitmaps or byte[]
What we have done.
Opened up camera.Took camera frame from onNextFrame method using Camera1.We could have used MediaRecorder for Recording the video but simultaneous frame rendering to surfaceView and video recording using camera1 cannot be done.So we have used MediaCodec to create mp4 video from frames so that frame rendering and recording a video can be done.

MediaMuxer does't record video. Help me to solve the trouble

I record a video from byte array using MediaCodec and MediaMuxer. But the result is that the video cannot be recorded. The system says: "File incorrect". You can see the code example below. I need to get a video file in mp4 format. Please tell me what the problem it is.
