I want to play a video from my assets or raw folder

Question

I want to play a video from my assets or raw folder in my app in Android using VideoView I am getting the error as video cannot be played please anyone give me a solution.

Here is the code I used

VideoView vd = (VideoView)findViewById(R.id.Video);         
Uri uri = Uri.parse("android.resource:"  + R.raw.video);
MediaController mc = new MediaController(this);
vd.setMediaController(mc);
vd.setVideoURI(uri); 
vd.start();

Answer 1

A few things to note:

1. You must copy the video into your project's res/raw folder.
2. It must be in a supported format (3gp, wmv, mp4 ) and named with lower case, numerics, underscores and dots in its filename: my_video_file.mp4
3. When you work with this resource in code, you will reference through the generated R statics - it will have the file extension removed: R.raw.my_video_file
4. The Activity class has a helper method getPackageName() which can be used by your code when constructing the correct URI to your video.

VideoView vv = (VideoView)this.findViewById(R.id.videoView)
String uri = "android.resource://" + getPackageName() + "/" + R.raw.my_video_file;
vv.setVideoURI(Uri.parse(uri));
vv.start();

There is more information on this here .

Answer 2

You must include the package name in the uri:

  Uri uri = Uri.parse("android.resource://[package]/raw/video")

or

  Uri uri = Uri.parse("android.resource://[package]/"+R.raw.video);

There are so many ways to go wrong with VideoView ! Mainly because the logcat gives you no help, always giving error UNKNOWN.

I found this link was by far the best way to get started... A complete description so you can't go wrong. Thanks go to the author...

Answer 4

When we include a video resource in /resource/raw/ or assets/ , by default, it looks for the .mp4 format, it won't accept .wmv files. If you read video file from external locations(like: /mnt/sdcard/demo.wmv ) then it'll accept them.

Answer 5

Try:

   AssetFileDescriptor afd = getAssets().openFd(fileName);
   player.setDataSource(afd.getFileDescriptor(),afd.getStartOffset(), afd.getLength());

Answer 6

确保写入没有扩展名的文件视频名称。
