how to use hw accelerator with FFMpegFrameRecorder

I try to use mobile hardware accelerator with FFMpegFrameRecorder, but software only is used :

private fun initFFMpegRecorder() { ffmpeg_link = File(StorageUtils.createPhoneVideoFileName(context))

    yuvImage = Frame(1920, 1080, Frame.DEPTH_UBYTE, 2)
    Log.i(LOG_FFMPEG, "create yuvImage")

    ffMpegFrameRecorder = FFmpegFrameRecorder(
        ffmpeg_link,
        1920,
        1080,
        1
    )
    ffMpegFrameRecorder?.format = "mkv"

    ffMpegFrameRecorder?.sampleRate = sampleAudioRateInHz
    ffMpegFrameRecorder?.audioBitrate = 128 * 1024
    ffMpegFrameRecorder?.audioCodec = avcodec.AV_CODEC_ID_AAC

    ffMpegFrameRecorder?.setVideoMetadata("rotate", "90")

    ffMpegFrameRecorder?.frameRate = 30.toDouble()
    ffMpegFrameRecorder?.videoBitrate = 6 * 1000 * 1024
    ffMpegFrameRecorder?.gopSize = 30
    ffMpegFrameRecorder?.isInterleaved = true
    ffMpegFrameRecorder?.videoCodec = avcodec.AV_CODEC_ID_H264
    ffMpegFrameRecorder?.pixelFormat = avutil.AV_PIX_FMT_YUV420P

    ffMpegFrameRecorder?.videoCodecName = "h264_mediacodec"

    ffMpegFrameRecorder?.timestamp = 1000 * (System.currentTimeMillis() - startTime)
    ffMpegFrameRecorder?.setVideoOption("preset", "ultrafast")
    ffMpegFrameRecorder?.setVideoOption("tune", "zerolatency")

    Log.i(
        LOG_FFMPEG,
        "recorder video initialize success"
    )

    audioRecordRunnable = AudioRecordRunnable()
    audioThread = Thread(audioRecordRunnable)
    runAudioThread = true
    Log.i(
        LOG_FFMPEG,
        "recorder audio initialize success"
    )
}

fun startRec() { initFFMpegRecorder()

        try {
            val avCodec: AVCodec? = avcodec.avcodec_find_encoder_by_name("h264_mediacodec")
            if (avCodec != null) {
                Log.i(
                    "SUPPORT_ENCODER_TELEPHONE",
                    "avCodec != null, " + avCodec.name().getString()
                        .toString() + "/ " + avCodec.long_name().getString()
                )
            } else {
                Log.i("SUPPORT_ENCODER_TELEPHONE", "avCodec == null")
            }

            ffMpegFrameRecorder?.start()
            startTime = System.currentTimeMillis()
            recording = true
            audioThread?.start()
            isRecordingVideo.set(true)
            Log.d(LOG_FFMPEG, "FFMpeg launched")
        } catch (e: FFmpegFrameRecorder.Exception) {
            e.printStackTrace()
        }

}

i can get rawVideo here (i am using Camera2 API and ImageReader) like this :

imageReader = ImageReader.newInstance(1920, 1080, ImageFormat.YUV_420_888, 1) imageReader?.setOnImageAvailableListener( mOnImageAvailableListener, mBackgroundHandler )

private val mOnImageAvailableListener = OnImageAvailableListener { p0 ->

            val image = p0.acquireNextImage()

            /* get video data */
            if (yuvImage != null && recording) {
                (yuvImage!!.image[0].position(0) as ByteBuffer).put(image!!.planes[0].buffer)

                val bytes = bzyuvUtil?.preHandleYUV420(image, false, 0)
                val newBytes = ByteArray(1920 * 1080 * 3 / 2)
                BZYUVUtil.yuvI420ToNV21(bytes, newBytes, 1920, 1080)
                (yuvImage!!.image[0].position(0) as ByteBuffer).put(newBytes)

                try {
                    Log.v(
                        LOG_FFMPEG,
                        "Writing Frame Telephone"
                    )
                    val t = 1000 * (System.currentTimeMillis() - startTime)
                    if (t > ffMpegFrameRecorder?.getTimestamp()!!) {
                        ffMpegFrameRecorder?.setTimestamp(t)
                    }

                    ffMpegFrameRecorder?.record(yuvImage)
                    isRecordingVideo.set(true)
                } catch (e: FFmpegFrameRecorder.Exception) {
                    Log.v(
                        LOG_FFMPEG,
                        e.message!!
                    )
                    e.printStackTrace()
                }
            }

            image?.close()
        }
    }
}

Any help will be appreciated
