Describe the bug
I changed AddTextOnVideo feature to add text on Image.
Here are queries. but when I run this command, I can see error ffmpeg error initializing filter 'drawtext' with args
Please help me

This is my sample code.

private fun addTextProcess(imagePath: String) {
        val outputPath = Common.getFilePath(this, Common.IMAGE)
        val dateString = Date().dateToString("yyyy-MM-dd HH:mm:ss.SSS")
        val fontPath = Common.getFileFromAssets(this, "roboto_regular.ttf").absolutePath
        val query = ffmpegQueryExtension.addTextOnVideo(imagePath, dateString,
            0.0f,
            0.0f,
            fontPath = fontPath,
            isTextBackgroundDisplay = false,
            fontSize = 30,
            fontcolor = "red",
            output = outputPath
        )
        CallBackOfQuery().callQuery(query, object : FFmpegCallBack {
            override fun process(logMessage: LogMessage) {
                Log.d("Dalibor", logMessage.text)
            }

            override fun success() {
               Log.d("Dalibor", "Sucess")
            }

            override fun cancel() {
                addTimeStampToPhotos()
            }

            override fun failed() {
                addTimeStampToPhotos()
            }
        })
    }

@daliborristic883
Issue is here, "drawtext=............:x=0.0:y=0.0:..........."
Please give value of X and Y
for the calculation of X and Y value, get height and width of Image and convert into percentage form
ex. Image have height = 100% and width = 100%
and I want to display text in center then give value X=50.0% and Y=50.0%
