How to determine video width and height on Android

问题:

I have a video file and I want to get width and height of video. I don't want to play it, just to get size. I've tried to use MediaPlayer:

MediaPlayer mp = new MediaPlayer();
mp.setDataSource(uriString);
mp.prepare();
int width = mp.getVideoWidth();
int height = mp.getVideoHeight();

but it returns 0 for width and height, because VideoSizeChangedEvent didn't fire yet. How can I get width and height of video?

UPD: I need API version 7

回答1:

This works in API level 10 and up:

MediaMetadataRetriever retriever = new MediaMetadataRetriever();
retriever.setDataSource("/path/to/video.mp4");
int width = Integer.valueOf(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_WIDTH));
int height = Integer.valueOf(retriever.extractMetadata(MediaMetadataRetriever.METADATA_KEY_VIDEO_HEIGHT));
retriever.release();

try with this code and let me know if any issues..

MediaMetadataRetriever retriever = new  MediaMetadataRetriever();
Bitmap bmp = null;      

try 
{
    retriever.setDataSource("...location of your video file");
    bmp = retriever.getFrameAtTime();
    videoHeight=bmp.getHeight();
    videoWidth=bmp.getWidth();
}

This worked for me

videoView.setOnPreparedListener(new MediaPlayer.OnPreparedListener() {
            @Override
            public void onPrepared(final MediaPlayer mp) {
                int width = mp.getVideoWidth();
                int height = mp.getVideoHeight();
            }
        });

API level 7 solution:

// get video dimensions
MediaPlayer mp = new MediaPlayer();
        try {
            mp.setDataSource(filename);
            mp.prepare();
            mp.setOnVideoSizeChangedListener(new OnVideoSizeChangedListener() {
                @Override
                public void onVideoSizeChanged(MediaPlayer mp, int width, int height) {

                    int orient = -1;

                    if(width < height)
                        orient = 1;
                    else
                        orient = 0;

                }
            });
        } catch (IllegalArgumentException e) {
            e.printStackTrace();
        } catch (SecurityException e) {
            e.printStackTrace();
        } catch (IllegalStateException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }

private static final Uri MOVIE_URI = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
private static final String[] MOVIE_PJT = new String[] {
        MediaStore.Video.Media._ID, MediaStore.Video.Media.DATA,
        MediaStore.Video.Media.TITLE, MediaStore.Video.Media.DATE_TAKEN,
        MediaStore.Video.Media.MIME_TYPE, MediaStore.Video.Media.DURATION,
        MediaStore.Video.Media.SIZE, MediaStore.Video.Media.RESOLUTION };

try this to query from system content provider. It will return some useful info of the Videos(local files)

This set of utilities to work with the Size abstraction in Android.

It contains an class SizeFromVideoFile.java You can use it like this:

ISize size = new SizeFromVideoFile(videoFilePath);
size.width();
size.hight();
