Trim and Merge issue

[AsynctaskCoffee]

When I trim and merge multiple videos I can see there are some glitches from output video (on video switches).

I am using

` private lateinit var builder: TranscoderOptions.Builder private var mTranscodeVideoStrategy: TrackStrategy? = null

private var mTranscodeOutputFile: File? = null

init {
    mTranscodeVideoStrategy = DefaultVideoStrategy.Builder()
        .addResizer(MyExactResizer(1080, 1920))
        .frameRate(30)
        .build()
}

fun setVideos(
    mTranscodeOutputFile: File?,
    videoList: ArrayList<AnalyzeResult>,
    context: Context,
    musicPath: String?
) {
    this.mTranscodeOutputFile = mTranscodeOutputFile
    builder = Transcoder.into(mTranscodeOutputFile!!.absolutePath)
    videoList.forEach {
        val start: Long = (max(0, it.startMs!!) * 1000).toLong()
        val end: Long = (max(0, it.duration!! + it.startMs!!) * 1000).toLong()
        builder.addDataSource(
            TrackType.VIDEO,
            ClipDataSource(
                UriDataSource(context, Uri.parse(it.mediaPath)),
                start,
                end
            )
        )
    }
    musicPath?.let {
        builder.addDataSource(TrackType.AUDIO, context, Uri.parse(it))
    }
}

fun processVideo(transcoderListener: TranscoderListener) {
    builder
        .setListener(transcoderListener)
        .setVideoTrackStrategy(mTranscodeVideoStrategy)
        .transcode()
}`

Any recommendations ?
