Google Cast：加載元數據錯誤並且不存在Access-Control-Allow-Origin標頭

Question

我嘗試使用我的Android應用程序投射視頻流。 流來自我自己的網絡中的衛星接收器。 我通過http鏈接訪問流，例如：

http://192.168.188.23:8001/1:0:19:283D:3FB:1:C00000:0

當我在VLC中打開流時，我得到以下編解碼器信息：

類型：視頻/編解碼器：H264-MPEG-4 AVC（第10部分）（h264）

在我的應用中，我構建了此MediInfo：

private static MediaInfo buildMediaInfo(String title, String subTitle, String studio, String url, String imgUrl, String bigImageUrl, List<MediaTrack> tracks) {
    MediaMetadata movieMetadata = new MediaMetadata(MediaMetadata.MEDIA_TYPE_MOVIE);
    movieMetadata.putString(MediaMetadata.KEY_SUBTITLE, subTitle);
    movieMetadata.putString(MediaMetadata.KEY_TITLE, title);
    movieMetadata.putString(MediaMetadata.KEY_STUDIO, studio);
    return new MediaInfo.Builder(url)
            .setStreamType(MediaInfo.STREAM_TYPE_LIVE)
            .setContentType("video/mp4")
            .setMetadata(movieMetadata)
            .setMediaTracks(tracks)
            .build();
}

來自我的Chromecast的錯誤日志：

我無法在信息流本身上更改某些內容。

這是我的代碼中的問題還是來自Sat-Receiver（流）的問題？當它來自我的Sat-Receiver時是否有解決方案？

編輯2：來自流的標頭看起來像這樣（用php捕獲）：

[0] => HTTP/1.0 200 OK
[1] => Date: Sat, 04 Oct 2014 18:38:23 GMT
[2] => Server: Apache/2.2.22 (Debian)
[3] => X-Powered-By: PHP/5.4.4-14+deb7u9
[4] => Connection: Close
[5] => Access-Control-Allow-Origin: *
[6] => Content-Type: video/mpeg

當我在VLC中打開流時，我得到以下編解碼器信息：

類型：視頻/編解碼器：H264-MPEG-4 AVC（第10部分）（h264）

Android代碼與上述相同。

使用自定義樣式的適配器和優化的代碼：

我在您的帖子中沒有看到任何問題，因此不確定您要問的是什么。 您提到的錯誤表明您遇到了chromecast所需的CORS問題（基於W3C要求），而Cast SDK方面您無能為力。
