我有一个使用H.264基线编码的Mandbrake转换的MP4文件。这流在浏览器中正常。
我创建了一个可以在视频中流式传输此视频的应用程序。我已经在4.0.1和4.3中进行了测试，而且效果很好。该视频播放很好。
使用2.3.3 Android模拟器，我可以听到声音，但没有视频。当我在实际的2.3.3设备（HTC EVO）中尝试它时，它根本无法播放视频。我得到了一个"无法播放的视频"错误。我不太确定是否在姜饼中得到支持，但是似乎是如此，因为仿真器至少可以播放音频。
我在logcat中看到了一些HDMI权限信息，但我不确定这是什么意思。感谢任何反馈。谢谢！
这是logcat：

快速查看developer.android.com上支持的媒体格式页面页面显示，在Android的所有版本上都支持H.264（.mp4）播放（假设我正在阅读图表正确地），因此视频中的播放应该有效。但是，在Android 3.0之前不支持从HTTPS URL流式传输，如果您确实尝试从HTTPS URL进行流式传输，这将导致错误。
