无法在我的Android应用程序播放MP4视频 [英] Can't play mp4 video in my Android app
本文介绍了无法在我的Android应用程序播放MP4视频的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我很想在我的Android应用程序中播放mp4视频。我甚至写了一点code吧：
I very want to play mp4 video in my android app. I even wrote a bit of code for it:
String sourceUrl = "http://tvstream.cn.ru/storage/1kanal/20120530/"
+ "1kanal-20120530-01-14-00-20120530-03-16-00.mp4";
final VideoView videoView = (VideoView) findViewById(R.id.videoView);
getWindow().setFormat(PixelFormat.TRANSLUCENT);
final MediaController mediaController = new MediaController(this);
mediaController.setMediaPlayer(videoView);
videoView.setMediaController(mediaController);
videoView.setVideoURI(Uri.parse(sourceUrl));
videoView.setOnPreparedListener(new OnPreparedListener() {
public void onPrepared(MediaPlayer mp) {
videoView.requestFocus();
videoView.start();
mediaController.show();
}
});
但是，没有什么工作:(当我启动我的应用程序在仿真器（安卓2.3.3）我有奇怪的堆栈跟踪的一些常见的错误codeS：
But nothing works :( When I launch my app in emulator (Android 2.3.3) I've got weird stacktrace with some common error codes:
几个小时关闭谷歌搜索和实验后，我决定尝试推出我的应用程序在真实的设备，看logcat的：

我试图找到一些有关OMX.qcom.video.de coder.avc]错误（0x8000100a，0），但没有发现什么有趣的。关于在客户端无法打开文件，试图服务器端计算器的问题有很多答案，但没有人帮助。
I try to find something about "OMX.qcom.video.decoder.avc] ERROR(0x8000100a, 0)", but didn't find nothing interesting. About "Couldn't open file on client side, trying server side" problem stackoverflow has many answers, but no one helped.
当我发动对ICS这个应用程序（在模拟器），我有类似的错误：

据我所知，Android支持具有H264播放的视频去codeD（http://developer.android.com/guide/appendix/media-formats.html）。所以，任何人都可以告诉我，我做错了。
As I know, Android supports playback of video decoded with h264 (http://developer.android.com/guide/appendix/media-formats.html). So, can anyone tell me what I do wrong.
推荐答案
可能是你的文件使用了不支持配置文件，请注意官方的媒体格式页面只列出的 Baseline Profile的的作为支持H.264 AVC。
Probably your file is using an unsupported profile, notice that official media formats page only lists Baseline Profile as supported for H.264 AVC.
尝试转码的视频指定的Baseline Profile在<一个建议href="http://superuser.com/questions/371460/command-encoding-h264-baseline-profile-level-1-with-ffmpeg-and-libx264">this计算器问题，也就是说，如果你的容器是MP4运行：
Try transcoding the video specifying Baseline Profile as suggested in this stackoverflow question, i.e. if your container is MP4 run:
ffmpeg -i yourfile.mp4 -c:v libx264 -profile:v baseline -level 1 yourfile_BaselineProfile.mp4
如果这个工作是不是在你的code一个问题，你只需要使用支持的格式。
If this works it's not a issue in your code, you just have to use supported formats.
