推荐答案

首先，不要使用模拟器进行测试的视频播放。它能够处理视频播放效果十分有限。用一个实际的Andr​​oid设备。

First, do not use the emulator for testing video playback. Its ability to handle video playback is very limited. Use an actual Android device.

其次，经常检查LogCat中（亚行logcat ，DDMS或DDMS透视图在Eclipse）的警告，当你遇到多媒体问题。的OpenCore - 使用Android的多媒体引擎 - 有一种倾向，记录错误级别的条件警告

Second, always check LogCat (adb logcat, DDMS, or DDMS perspective in Eclipse) for warnings when you run into multimedia problems. OpenCORE -- the multimedia engine used by Android -- has a tendency to log error-level conditions as warnings.

例如，您的视频文件可能不会被设置为渐进式下载，这是需要的HTTP流。在Linux上，您可以通过安装MP4Box和运行修补MP4视频的渐进式下载 MP4Box -hint＆LT;文件＆gt;

For example, your video file may not be set up for progressive download, which is required for HTTP streaming. On Linux, you can patch up MP4 videos for progressive download by installing MP4Box and running MP4Box -hint <file>.
