Hi,
Thanks for reporting this.
I cannot access your stream unfortunately.
This error typically means that the LG fairplay implementation might fail to handle your particular stream. To validate this, I recommend running the following test :

  • Open the stream URL in a new tab of Safari (either iOS or macOS)
  • Start Airplaying
  • Check whether the behaviour is the same

Also, please feel free to share your test stream. It might not be possible to get detailed errors from the LG Airplay implementation, but looking into your stream might give us some leads.

Thanks in advance for your feedback.

The share link can’t play on Safari. I tested it using the BitmovinPlayerSamples.BasicPlayback demo(iOS project).

Hi @qiang.zhou,

Unfortunately, we have seen many issues with third-party AirPlay receivers, such as TVs. Because we do not have any control or insights into the AirPlay implementation on these receivers, we do not officially support them.

As you also found out, everything works fine when AirPlaying to an AppleTV, so we can assume it’s an issue on the LG TV.
