Can Chromecast play HLS stream with H264 video codec and without audio stream in it?

When I have created HLS stream without audio in it with supported H264 Baseline profile, I am able to play same stream on my vlc player with m3u8 file but same video I am not able to play on chromecast default receiver.

I had the same problem. It seems ChromeCast does not support HLS without audio.

The interesting thing is that if we want to play a simple video (e.g. mp4) without audio, ChromeCast is able to play it.

To cope with that issue I suggest to add a silent audio track to your TS files. Using FFMPEG you can add a silent audio track adding -f lavfi -i anullsrc parameters into your command line to create m3u8 files.

You can find more information about anullsrc here: https://trac.ffmpeg.org/wiki/Null

  • AES-128 encryption
  • Raw MP3 segments can be part of an HLS media playlist
