嘗試在視頻視圖中播放來自網址的視頻時，我收到一個FileNotFoundException：某些手機上沒有內容提供商錯誤

Question

我在服務器上有一個視頻，我想在視頻中播放。

在我的LG G專業版（4.1.2）上，它就像一個魅力，但它不適用於舊的nexus（4.1.2）和HTC Desire X（android 4.0.4）

這是我的代碼：

videoUrl = video.getUrl();
Uri videoUri = Uri.parse(videoUrl);
vvVideoFullscreen.setVideoURI(videoUri);

video.getUrl（）返回以下字符串：

http://sdf.mysite.com/upload/video/456456.mp4

非常直截了當。 我該怎么辦？

我被告知視頻文件具有正確的mp4壓縮格式：h.264基線，如http://developer.android.com/guide/appendix/media-formats.html所述

這是錯誤日志：

 D/MediaPlayer(3963): setDataSource(Context context,  http://sdf.mysite.com/upload/video/456456.mp4, Map<String, String> headers) in
 E/MediaPlayer(3963): java.io.FileNotFoundException: No content provider:  http://sdf.mysite.com/upload/video/456456.mp4
 V/MediaPlayer(3963): network type=wifi

此外，我嘗試通過這種方式播放視頻：

    Uri videoUri = Uri.parse(videoUrl);

    Intent intent = new Intent(Intent.ACTION_VIEW, videoUri);
    intent.setDataAndType(videoUri, "video/mp4");
    startActivity(intent);

但是我得到了以下日志消息（視頻沒有播放）

嘗試從原始文件夾播放視頻，但仍然無法這樣做：

Answer 1

MediaPlayer類實際上是android中子系統的前端，稱為媒體播放器服務。 這種失敗的設備很可能缺乏對h264的供應商支持。 例如，根據我使用各種機頂盒設備的經驗，該系統在其供應商實現方面有所不同。

另外，chrome for android通過一系列生成的Jni綁定使用MediaPlayer類，所以如果你的設備支持h264，它應該在chrome中工作。 不幸的是，我不認為有一個簡單的解決方案，因為h264支持無處不在。 如果您可以控制媒體本身，則可以嘗試切換到webm。

Answer 2

你應該嘗試mediacontroller

try {
        // Start the MediaController
        MediaController mediacontroller = new MediaController(
                videoscrnplay.this);
        mediacontroller.setAnchorView(vdov);

        // Get the URL from String VideoURL
        Uri video = Uri.parse(VideoURL);
        vdov.setMediaController(mediacontroller);
        vdov.setVideoURI(video);

    } catch (Exception e) {
        Log.e("Error", e.getMessage());
        e.printStackTrace();
    }
