Load artwork from URI in StyledPlayerView

Hello, i would like be able to add covers for mp3 streams , i tried this:

```
mediaItem = new MediaItem.Builder().setUri("https:// STREAM mp3").setMediaMetadata(
new com.google.android.exoplayer2.MediaMetadata.Builder()
.setTitle(" My Stream ")
.setArtworkUri(Uri.parse("https:// COVER .jpg"))
.build())
.build();
MediaSource mediaSource = mediaSourceFactory.createMediaSource(mediaItem);
return new ProgressiveMediaSource.Factory(HttpDataSourceFactory).createMediaSource(mediaItem);
```

I also tried after playing the stream:
```
player.setPlaylistMetadata( new com.google.android.exoplayer2.MediaMetadata.Builder()
.setTitle(" My Stream ")
.setArtworkUrii(Uri.parse("https:// COVER .jpg"))
.build());
```

None of these work but visulation still blank

Thanks for your help
