Chromecast WebVTT captions on a default receiver












0















So I am trying to setup closed captions for chromecast using the default chrome sender app, according to the docs this should be possible, as seen here.
I can't figure out why my code does not work. It is almost identical to the provided sample code.


The snipper probably does not work because it's too sandboxed, see it here in a normal html page:
Click!

One first should connect their chromecast using the top button, and then click on "load video".



My code:




var suburl = 'https://cors-anywhere.herokuapp.com/brenopolanski.com/html5-video-webvtt-example/MIB2-subtitles-pt-BR.vtt';

var mediaurl = 'https://cors-anywhere.herokuapp.com/www.w3schools.com/html/mov_bbb.mp4';

var mediaInfo;

window['__onGCastApiAvailable'] = function(isAvailable) {

  if (isAvailable) {

    initializeCastApi();

  }

};

initializeCastApi = function() {

  cast.framework.CastContext.getInstance().setOptions({

    receiverApplicationId:

      chrome.cast.media.DEFAULT_MEDIA_RECEIVER_APP_ID

  });

  var englishSubtitle = new chrome.cast.media.Track(1, // track ID

  chrome.cast.media.TrackType.TEXT);

  englishSubtitle.trackContentId = suburl;

  englishSubtitle.trackContentType = 'text/vtt';

  englishSubtitle.subtype = chrome.cast.media.TextTrackType.SUBTITLES;

  englishSubtitle.name = 'English Subtitles';

  englishSubtitle.language = 'en-US';

  englishSubtitle.customData = null;



  mediaInfo = new chrome.cast.media.MediaInfo(mediaurl);

  var textTrackStyle = new chrome.cast.media.TextTrackStyle();

  textTrackStyle.foregroundColor = '#80FF0000';



  mediaInfo.contentType = 'video/mp4';

  mediaInfo.metadata = new chrome.cast.media.GenericMediaMetadata();

  mediaInfo.customData = null;

  mediaInfo.streamType = chrome.cast.media.StreamType.BUFFERED;

  mediaInfo.textTrackStyle = textTrackStyle

  mediaInfo.duration = null;

  mediaInfo.tracks = [englishSubtitle];

  mediaInfo.activeTrackIds = [1];

};



function loadVideo() {

  var castSession = cast.framework.CastContext.getInstance().getCurrentSession();

  var request = new chrome.cast.media.LoadRequest(mediaInfo);

  castSession.loadMedia(request).then(

  function() { console.log('Load succeed'); },

  function(errorCode) { console.log('Error code: ' + errorCode); });

}

.cast-button, .load-button {

  max-width: 50px;

  max-height: 50px;

}

          After a lot of searching around I still cannot pinpoint the exact issue. I however stumbled on this amazing wrapper for the ChromeCast SDK which supports subtitles: https://github.com/Fenny/ChromecastJS/



          Including this demo: https://fenny.github.io/ChromecastJS/demo/index.html



          Hope this can help someone else!

          • Works for a simple scenario: files from the save server; CORS headers on each source. subtitles are in a separate WebVTT stream. Doesn't do any of the very heavy lifting required to go beyond that.

          After a lot of searching around I still cannot pinpoint the exact issue. I however stumbled on this amazing wrapper for the ChromeCast SDK which supports subtitles: https://github.com/Fenny/ChromecastJS/



          Including this demo: https://fenny.github.io/ChromecastJS/demo/index.html



          Hope this can help someone else!

          • Works for a simple scenario: files from the save server; CORS headers on each source. subtitles are in a separate WebVTT stream. Doesn't do any of the very heavy lifting required to go beyond that.

          A CLEAN and SIMPLE way to add appendices to Table of Contents and bookmarks

          Image
          0 I found a lot of questions abount appendices and ToC. Many users want appendices to be grouped in an Appendix part, however some problems arise with ToC, hyperref, PDF viewer bookmarks, and so on. There are different solutions which require extra packages, command patching and other extra code, however none of them satisfies me. I almost found an easy way to accomplish a good result, where appendices are added to bookmarks in the right way and hyperref links point to the right page. However, the number of the "Appendix" part page is wrong (it's the number of appendix A). Is there any EASY way to fix that? This is a MWE: documentclass{book} usepackage[nottoc,notlot,notlof]{tocbibind} usepackage{hyperref} begin{document} frontmatter tableofcontents mainmatter part{First} chapter{...

          Calculate evaluation metrics using cross_val_predict sklearn

          Image
          1 In the sklearn.model_selection.cross_val_predict page it is stated: Generate cross-validated estimates for each input data point. It is not appropriate to pass these predictions into an evaluation metric. Can someone explain what does it mean? If this gives estimate of Y (y prediction) for every Y (true Y), why can't I calculate metrics such as RMSE or coefficient of determination using these results? python scikit-learn cross-validation share | improve this question edited Nov 28 '18 at 17:52 desertnaut 20.3k 7 43 79 ...
