【问题描述】:
我有一个带有 VideoView 的应用程序,它正在播放内部存储中的 mp4 文件(我的包 files 目录)
在一些三星 Epic Touch 4g (Galaxy SII) 设备上,而不是正在显示的视频,屏幕是全黑的。我的应用程序中的所有其他内容都正常运行并响应,因此设备根本没有“冻结”,它只是在屏幕上显示黑色而不是视频。
要开始我的视频,我使用 onPreparedListener 回调来调用 start():
mVideoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
@Override
public void onPrepared(MediaPlayer arg0) {
mVideoView.start();
}
});
我将视频设置为在此通话中播放:
//file is the reference to my video File object.
//I am positive that it is correct
mVideoView.setVideoPath(file.getAbsolutePath());
我有一个这样的 onErrorListener 设置:
mVideoView.setOnErrorListener(new OnErrorListener(){
@Override
public boolean onError(MediaPlayer arg0, int arg1, int arg2) {
Log.i(myTag, "MP ERROR: "+ arg1 + " - " + arg2);
/* I have also tried this here, no luck this way either
mVideoView.setVideoPath(file.getAbsolutePath());
return true;
*/
return false;
}
});
经过仔细检查,我意识到我的 onErrorListener 根本没有收到回调。
虽然屏幕上一片漆黑,但日志却一遍又一遍地收到这些消息:
V/PlayerDriver(2579): HandleInformationalEvent: PVMFInfoProcessingFailure
V/PlayerDriver(2579): HandleInformationalEvent: type=16 UNHANDLED
E/MFC_DEC_APP(2579): SsbSipMfcDecExe] IOCTL_MFC_DEC_EXE failed(ret : -2001)
E/PVMFOMXVideoDecNode(2579): Ln 1652 OMX_EventError nData1 -2147479541 nData2 0
并且(有时后面的行会与上述 4 行的垃圾邮件相互穿插。但其他时候,在上述 4 行的多次垃圾邮件迭代后,这两行会自行发送垃圾邮件。)
W/MediaPlayer(30537): info/warning (1, 16)
I/MediaPlayer(30537): Info (1,16)
我不认为这是我的视频 (AVC MP4) 的编码问题,因为完全相同的视频可以在一些 Epic Touch 4g 设备上正常运行(甚至某些在相同版本的操作系统上) )。而且我过去在这台设备上使用过完全相同的视频,当设备升级到操作系统版本 2.3.6 时,这些问题就开始出现了。
谁能解释我看到的 OMX/MFC 错误?或者有没有其他人对 VideoView 只显示黑屏而不是视频有问题?最后,我应该以其他方式启动视频文件的准备/播放,而这可能不会导致这些错误和黑屏吗?
编辑:我在 this file 发现警告 #16 是:
/*
Notification that a processing failure occurred (not fatal error)
*/
const PVMFStatus PVMFInfoProcessingFailure = 16;
这应该是一个非致命错误。我想它没有崩溃,所以它不是“致命的”,但无论发生什么都会导致我的视频无法正常显示。
编辑 2:视频开始时来自设备的更多日志。这些都出现在上述垃圾邮件之前:

【问题讨论】:
-
在有此问题的设备上重新安装您的应用程序有什么不同吗?我想知道视频文件是否以某种方式在内部存储中损坏或类似的东西。
-
不 =/。我已经尝试重新安装,甚至保持安装状态,但删除了视频文件,这样它就可以获取一个新的副本,但也没有运气。
-
以防万一这可能会有所帮助:我怀疑此 SsbSipMfcDecAPI.c 文件中的第 231 行正在生成错误消息。代码 -2001 似乎根据其header file 指定了 MFC_RET_DEC_EXE_TIME_OUT。虽然不知道如何修复:)
-
这种情况仅发生在您创建的特定 mp4 文件,还是 Android 2.3.6 上的所有 mp4 文件类型?
-
我尝试过的每个 mp4 文件都会发生这种情况。 (大约六个,都在具有旧操作系统的同一设备上工作,并且都在具有相同操作系统的同一设备的某些实例上工作。)
