Android libVLC - 文件路径而不是URL错误

Question

我正在使用来自here的Gary示例。

唯一的修改是，我打开一个本地视频这样的：

mMediaUrl = "/storage/emulated/0/MyFolder/20161003_1217.mp4"; 

，我得到以下错误：

10-03 12:54:13.588 16681-17397/windylabs.com.vlcplayersample E/VLC-std: Warning: input_item_SetURI("/storage/emulated/0/MyFolder/20161003_1217.mp4"): file path instead of URL. 
10-03 12:54:13.588 16681-17397/windylabs.com.vlcplayersample E/VLC-std: input_SplitMRL("/storage/emulated/0/MyFolder/20161003_1217.mp4") probably not a valid URI! 
10-03 12:54:15.718 16681-17399/windylabs.com.vlcplayersample E/VLC: [dece4214] core input: open of `/storage/emulated/0/MyFolder/20161003_1217.mp4' failed 
10-03 12:54:15.728 16681-17399/windylabs.com.vlcplayersample E/VLC: [dece4214] core input: Your input can't be opened 
10-03 12:54:15.728 16681-17399/windylabs.com.vlcplayersample E/VLC: [dece4214] core input: VLC is unable to open the MRL '/storage/emulated/0/MyFolder/20161003_1217.mp4'. Check the log for details. 

我不知道从哪里上的错误指定的日志是。这个例子中，来自here的视频流正在运行，但是我的SD卡上的视频未播放！

Answer 1

我已经找到了解决方案，可能会帮助某人，某个时候。

你需要下载的文件是这样的：

mMediaUrl = Uri.fromFile(pathToMediaFile).toString(); 

Answer 2

试试这个

mMediaUrl = "/sdcard/MyFolder/20161003_1217.mp4"; 

或在清单检查READ_EXTERNAL_STORAGE许可。
