Поток Android RTSP в формате MJPG: ⇐ Android

[Anonymous]

Я использую libvlc для доступа к потоку RTSP (формат MJPEG) с сетевой камеры в локальной сети (rtsp://192.168.0.51:8554/MCDE3000).
Приведенный ниже код отлично работает для Интернет-RTSP. Потоки (формат H.264).
Мой код Kotlin:
class VLCStreamActivity : AppCompatActivity() {

private lateinit var vlcVideoLayout: VLCVideoLayout
private var libVLC: LibVLC? = null
private var mediaPlayer: MediaPlayer? = null

override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)

setContentView(R.layout.activity_vlcstream)

// Initialize VLCVideoLayout
vlcVideoLayout = findViewById(R.id.vlc_video_layout)

// Initialize LibVLC
val options = arrayListOf(
"-vv", // Enable verbose logging
"--rtsp-frame-buffer-size=2000", // Adjust buffer size if necessary
"--network-caching=1500"
)
libVLC = LibVLC(this, options)

// Initialize MediaPlayer
mediaPlayer = MediaPlayer(libVLC).apply {
attachViews(
vlcVideoLayout,
null,
false,
false
)
}

// Play RTSP Stream
val media = Media(libVLC, Uri.parse("rtsp://192.168.0.51:8554/MCDE3000")).apply {
setHWDecoderEnabled(true, false) // Enable hardware decoding
addOption(":network-caching=3000") // Increase network caching to 3 seconds
addOption(":rtsp-tcp") // Force RTSP over TCP
addOption(":rtsp-timeout=60") // Extend the RTSP timeout to 60 seconds
addOption(":live-caching=3000") // Additional caching for live streams
addOption(":rtsp-frame-buffer-size=5000") // Increase buffer size
addOption(":demux=mjpeg") // Specify MJPEG as the demuxer

}
mediaPlayer?.media = media
media.release()

try {
mediaPlayer?.play()
} catch (e: Exception) {
Log.e("RTSPStreamActivity", "Error playing RTSP stream", e)
Toast.makeText(this, "Unable to play the stream.", Toast.LENGTH_SHORT).show()
}
}
}

Разумеется, разрешение ИНТЕРНЕТ было включено и IP-адрес был добавлен в network_security_config.xml.
В журнале видно, что камера успешно подключена: ввод: rtsp://192.168.0.51:8554/MCDE3000' успешно открыт
Однако через 10 секунд я получил сообщение об ошибке: доступ к libvlc: данные не получены. 10 секунд, прерывание
