英文:
How to load metadata directly from chromecast receiver?
问题
我尝试使用以下代码从发送方发送元数据到接收方，代码正常运行。
const mediaInfo = new chrome.cast.media.MediaInfo(url, type);
/* --------------------------------------------- */
mediaInfo.metadata = new chrome.cast.media.GenericMediaMetadata();
mediaInfo.metadata.metadataType = chrome.cast.media.MetadataType.GENERIC;
mediaInfo.metadata.title = title;
/* --------------------------------------------- */
const request = new chrome.cast.media.LoadRequest(mediaInfo);
但现在我尝试在接收方内部进行API调用，并尝试直接从接收方加载元数据。
是否有方法可以这样做？
如果可以，如何操作？我查阅了很多Chromecast接收方设置页面，但没有找到这样做的方法。
非常感谢您的帮助。谢谢。
英文:
I tried sending metadata from the sender to the receiver using the following code which is working fine.
const mediaInfo = new chrome.cast.media.MediaInfo(url, type);
/* --------------------------------------------- */
mediaInfo.metadata = new chrome.cast.media.GenericMediaMetadata();
mediaInfo.metadata.metadataType = chrome.cast.media.MetadataType.GENERIC;
mediaInfo.metadata.title = title;
/* --------------------------------------------- */
const request = new chrome.cast.media.LoadRequest(mediaInfo);
But now I am trying to make an api call inside the receiver itself and trying to load metadata directly right from the receiver itself.
Is there a way to do that?
If so how to do that? I went through so many pages of chromecast receiver setup and couldn't find a way to do that.
Your help is largely appreciated. Thanks.

你需要在加载时使用 setMessageInterceptor，调用 API 并将数据设置到 metaData 中，然后添加到 loadRequestData 中。
最后返回 loadRequestData。
const context = cast.framework.CastReceiverContext.getInstance();
const MediaMetadata = new cast.framework.messages.MediaMetadata();
const playerManager = context.getPlayerManager();
playerManager.setMessageInterceptor(
cast.framework.messages.MessageType.LOAD, loadRequestData => {
return fetch('thirdpartyapi')
.then(response => response.json())
.then(data => {
MediaMetadata.title = '你的标题'
MediaMetadata.subtitle = '你的副标题'
loadRequestData.media.metadata = MediaMetadata
return loadRequestData;
})
});
英文:
You need to use setMessageInterceptor on load and call the api and set the data on metaData and add to loadRequestData
last return the loadRequestData
const context = cast.framework.CastReceiverContext.getInstance();
const MediaMetadata = new cast.framework.messages.MediaMetadata()
const playerManager = context.getPlayerManager();
/* --------------------------------------------- */
playerManager.setMessageInterceptor(
cast.framework.messages.MessageType.LOAD, loadRequestData => {
return fetch('thirdpartyapi')
.then(response => response.json())
.then(data => {
MediaMetadata.title = 'your.Title'
MediaMetadata.subtitle = 'your.Subtitle'
/* --------------------------------------------- */
loadRequestData.media.metadata = MediaMetadata
/* --------------------------------------------- */
return loadRequestData;
})
});
