It is posible to cast or stream (Android-Chromecast) a local File?

Question

I am developing a little music Player and I am trying to cast the current song to Chromecast. My app is based on Folders, so I manage mp3 or flac Files as songs.

I am following this Google Developers tutorial and I have written my Android Sender with the Media Chanel. If I do this, a song uploaded to dropbox plays succesfully on my TV.

    MediaMetadata mediaMetadata = new MediaMetadata(MediaMetadata.MEDIA_TYPE_MUSIC_TRACK);

    MediaInfo mediaInfo = new MediaInfo.Builder(
    "https://dl.dropboxusercontent.com/u/56292608/MySong.mp3")
    .setContentType("audio/mp3")
    .setStreamType(MediaInfo.STREAM_TYPE_BUFFERED)
    .setMetadata(mediaMetadata)
    .build()

mRemoteMediaPlayer.load(mApiClient, mediaInfo, true)

Is any way to cast or stream a File in order to set an URL?

I try with:

Uri.fromFile(myFile).toString()

but i can't send the file. Is any way to build the MediaInfo object reference from a local File path? If not, is any easy way to create a stream from a local path and send this stream to Chromecast?

In other case, it would be better transfering directly the multimedia sound from device with another approach?

Thanks for all

Answer 1

It is possible. Most ways that I have encountered involve:

1. Create a barebones HTTP web server on the Android device.
2. Direct Chromecast to stream from your phone using the web server.
3. The web server then streams the file to the Chromecast.
