Agora API Javascript 中的 Addview 功能不起作用
Agora API Addview function in Javascript doesn't work
我正在尝试使用 Agora API
一切正常,但我的 Javascript 中创建容器以查看我的网络摄像头的 Addview 函数不起作用
我听了"stream-subscribed"事件后调用了,但是没有用
我发现它不听 "stream-added" 事件我不知道为什么>
请注意:
我加了App_ID
我添加了频道名称
我添加了令牌
感谢帮助

您需要将事件回调移到加入频道成功之外。客户端回调需要在与客户端初始化相同的块内发生。
等待 joinChannel 成功,为时已晚,引擎在添加侦听器之前触发了事件。
使用上面的 JS 代码,它应该如下所示:
// rtc object
var rtc = {
client: null,
joined: false,
published: false,
localStream: null,
remoteStreams: [],
params: {}
};
// Options for joining a channel
var option = {
appID: "MY_APP_ID",
channel: "MY_Channel_Name",
uid: null,
token: "Channel_Token"
}
$('#create').click(function() {
// Create a client
rtc.client = AgoraRTC.createClient({
mode: "live",
codec: "h264"
});
// Initialize the client
rtc.client.init(option.appID, function() {
console.log("init success");
// The value of role can be "host" or "audience".
rtc.client.setClientRole("host");
// define callbacks before joining the channel
rtc.client.on("stream-added", function(evt) {
var remoteStream = evt.stream;
var id = remoteStream.getId();
if (id !== rtc.params.uid) {
rtc.client.subscribe(remoteStream, function(err) {
console.log("stream subscribe failed", err);
})
}
console.log('stream-added remote-uid: ', id);
});
rtc.client.on("stream-subscribed", function(evt) {
var remoteStream = evt.stream;
var id = remoteStream.getId();
// Add a view for the remote stream.
addView(id);
// Play the remote stream.
remoteStream.play("remote_video_" + id);
console.log('stream-subscribed remote-uid: ', id);
})
// Join a channel
rtc.client.join(option.token ? option.token : null, option.channel, option.uid ? +option.uid : null, function(uid) {
console.log("join channel: " + option.channel + " success, uid: " + uid);
rtc.params.uid = uid;

rtc.localStream = AgoraRTC.createStream({
