如何设置/更改专辑封面？ [英] How to set/change album art?

问题描述

我正在构建一个具有chromecast支持的Cordova icecast应用程序。到目前为止，我得到了它的工作，感谢一个插件，模仿官方的Chrome api非常密切。

I'm building a Cordova icecast app that has chromecast support. So far I got it working thanks to a plugin that mimmicks the official Chrome api quite closely.

事情是：我想设置Styled Media Receiver的专辑封面但我无法让它工作.. anybode有这样的例子吗？

The thing is: I want to set the album art of the Styled Media Receiver but I can't get it to work.. Does anybode have an example of this?

我当前的代码（片段）

var mediaInfo = new chrome.cast.media.MediaInfo(station.station_url);
mediaInfo.contentType = "audio/mpeg";
mediaInfo.metadata = new chrome.cast.media.MusicTrackMediaMetadata();
mediaInfo.metadata.title = station.station_name;
mediaInfo.metadata.images = [
    new chrome.cast.Image(station.station_icon), // ex: http://www.thestation.com/icon.png
    new chrome.cast.Image("img/web_hi_res_512_001.png") // fallback
];

编辑1：在chrome.cast.Image（）之前添加'new'，而不是它有帮助但是这是应该如何完成的：）

EDIT 1: added 'new' before chrome.cast.Image(), not that it helps but this is how it's supposed to be done :)

编辑2：现在我们讨论使用Chrome API设置图像的问题：我可以在世界上如何更新没有调用loadMedia的图像？我认为我需要使用sendMessage但我不知道如何格式化消息。有一个页面讨论发送消息并提及图像，但它没有举例 - 这基本上使它无用： https://developers.google.com/cast/docs/reference/messages

EDIT 2: now we're on the subject of setting images using the Chrome API: how in the world can I update the image without calling loadMedia? I think that I need to use sendMessage but I don't know how to format the message. There is a page that talks about sending messages and it mentions images, but it doesn't give an example - which basically makes it useless: https://developers.google.com/cast/docs/reference/messages

推荐答案

事实证明我使用的cordova插件实际上并没有对我存储在mediaInfo对象中的元数据做任何事情。它可能有点令人困惑，因为它很好地模仿Chrome API，以至于你忘记它实际上是使用Android API与chromecast进行通信。

Turns out that the cordova plugin I use doesn't actually do anything with the metadata I stored in the mediaInfo object. It can be a bit confusing that it mimics the Chrome API so well that you forget it's actually using the Android API to communicate with the chromecast.

所以我想我会fork那个项目并尝试自己修复它。感谢所有回复等。

So I guess I'll fork that project and try to fix it myself. Thanks for all the replies and such.
