Chromecast Player #

Due to Google Chromecast limitations, Chromecast does not support audio and video delivered separately. To avoid potential issues with playback, we recommend using DASH, instead of HLS, which is a Chromecast supported use case.

This code snippet added to the receiver app will allow the player to use either the HLS or DASH manifest as needed on the web, but force a Chromecast to swap to the DASH manifest on the fly.

// In Chromecast Receiver App, always swap to DASH
const playerManager = context.getPlayerManager();

playerManager.setMessageInterceptor(
  cast.framework.messages.MessageType.LOAD,
  (loadRequestData) => {
    if (loadRequestData.media.contentId) {
      loadRequestData.media.contentId = loadRequestData.media.contentId.replace(
        "m3u8",
        "mpd"
      );
    } else {
      loadRequestData.media.contentUrl =
        loadRequestData.media.contentUrl.replace("m3u8", "mpd");
    }
    loadRequestData.media.contentType = "application/dash+xml";

    return loadRequestData;
  }
);
