Looking through the code it looks like RTSP url’s cannot work for 2 reasons:

  • The code checks if the url is valid by using java’s HTTPUrlConnection in the “URL exists” call, the HTTPURLConnection object does not support RTSP stream
  • Furthermore, even if you were to remove that check and recompile the engine, the url is passed to Android’s MediaExtractor. This class does not support RTSP streams.

In conclusion, I don’t believe RTSP is supported through the AndroidMediaPlayer

For details, here are logs from a UE 4.27.2 app running on the Oculus Quest 2 showing the errors.

I’m using a Quest 2, do you know what can cause the mute stream playback on Android ?

I’m using m3u8 stream format, the video works great in HD, but I get no sound

I only have one m3u8 URL that works with audio+video but it’s not a live stream
Maybe audio codec issue ?

Thank you
