ios - Chromecast 无法播放已保存的视频
<p><p>好的，我正在为 IOS 上的 chrome cast 开发一个应用程序。我的应用程序将执行的功能之一是从您的设备播放本地视频。为此，我使用了在 github 上找到的名为 <a href="https://github.com/robbiehanson/CocoaHTTPServer" rel="noreferrer noopener nofollow">CocoaHttpServer.</a> 的外部源。这个 Http 服务器允许我将文件上传到 localhost 服务。为此，我使用以下代码启动我的服务器:</p>
<pre><code>- (void)viewDidLoad
{
;
// Do any additional setup after loading the view from its nib.
// Configure our logging framework.
// To keep things simple and fast, we're just going to log to the Xcode console.
];
// Create server using our custom MyHTTPServer class
httpServer = [ init];
// Tell the server to broadcast its presence via Bonjour.
// This allows browsers such as Safari to automatically discover our service.
;
// Normally there's no need to run our server on any specific port.
// Technologies like Bonjour allow clients to dynamically discover the server's port at runtime.
// However, for easy testing you may want force a certain port so you can just hit the refresh button.
// ;
// Serve files from our embedded Web folder
NSString *webPath = [[ resourcePath] stringByAppendingPathComponent:@"Web"];
DDLogInfo(@"Setting document root: %@", webPath);
;
;
gblvb = ;
self.mediaControlChannel = [ init];
self.mediaControlChannel.delegate = self;
;
;
}
</code></pre>
<p>然后此代码设置我的 http 服务器并将其指向导入到我的主包中的 web 文件夹并包含我从谷歌下载用于测试目的的测试视频(谷歌在他们的流式传输示例中使用此视频通过网络转换的 Chrome )。我从 <a href="http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4" rel="noreferrer noopener nofollow">http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/BigBuckBunny.mp4</a> 获得了这个视频.除此之外，代码还设置了一个新的媒体 channel ，准备好让 chrome cast 转换到...</p>
<p>接下来我有我的 void 函数 <code>startServer</code> 真正建立连接并发布服务器...</p>
<pre><code>- (void)startServer
{
// Start the server (and check for problems)
NSError *error;
if()
{
DDLogInfo(@"Started HTTP Server on port %hu", );
}
else
{
DDLogError(@"Error starting HTTP Server: %@", error);
}
}
</code></pre>
<p>最后，下面的代码将路径设置为与 localhost url 相同，并将视频转换到 chrome cast:</p>
<pre><code>-(void)viewDidAppear:(BOOL)animated
{
path = , @"/", @"BigBuckBunny.mp4"];
// Do any additional setup after loading the view from its nib.
gblvb = [ GlobalVariables singleobj];
deviceScanner = [ init];
;
;
NSString *image;
NSString *type;
GCKMediaMetadata *metadata = [ init];
image = @"Folder-Video-icon.png";
[metadata setString:@"The MP4 file format defined some extensions over the ISO Base Media File Format to support MPEG-4 visual/audio codecs and various MPEG-4 Systems features such as object descriptors and scene descriptions."
forKey:kGCKMetadataKeySubtitle];
type = @"video/mp4";
forKey:kGCKMetadataKeyTitle];
initWithURL:[ initWithString:image]
width:480
height:360]];
//define Media information
sleep(2);
GCKMediaInformation *mediaInformation =
[ initWithContentID:path
streamType:GCKMediaStreamTypeNone
contentType:type
metadata:metadata
streamDuration:0
customData:nil];
//cast video
;
NSLog(@"Full Path : %@", path);
}
</code></pre>
<p>现在我的问题是，当此 http 服务器已发布并准备转换时，即使当我实际导航到 safari 上的路径时，chrome cast 也不会播放它，视频显示完美。除此之外，我知道 chrome cast 可以正常播放，因为它可以播放 google 的在线示例视频。</p>
<p><strong>编辑</strong>
这是我的调试日志，来自 chrome cast:</p>

<p>任何帮助将不胜感激。</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我解决了这个问题，而不是在模拟器上使用 localhost 进行测试，而是编写了一个函数来获取当前设备的 IP 地址以及 localhost 部分在这一行中的位置 <code>path = , @"/", @"BigBuckBunny.mp4"];</code>替换成设备ip地址。</p></p>
