android调用本地录制程序获取录制文件路径的问题(摘)
I use the MediaStore.ACTION_VIDEO_CAPTURE intent class to capture the video, the video stored in default location(gallery),i want to store the video in specific location with specific name.
I use MediaStore.EXTRA_MEDIA_TITLE and MediaStore.EXTRA_MEDIA_OUTPUT but I don`t get the video at correct location, at least I need the path of recorded video.
方案一:
Trick is to insert media into database before recording:
String fileName = "captureTemp.mp4";
ContentValues values = new ContentValues();
values.put(MediaStore.Video.Media.TITLE, fileName);
cameraVideoURI = getContentResolver().insert(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, cameraVideoURI);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 0);
intent.putExtra(MediaStore.EXTRA_SIZE_LIMIT, MAXIMUM_VIDEO_SIZE);
startActivityForResult(intent, CAPTURE_VIDEO_INTENT);
and then onActivityResult() use saved cameraVideoUri to reference recorded video:
String[] projection = { MediaStore.Video.Media.DATA, MediaStore.Video.Media.SIZE };
Cursor cursor = managedQuery(cameraVideoURI, projection, null, null, null);
int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA);
int column_index_size = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.SIZE);
cursor.moveToFirst();
String recordedVideoFilePath = cursor.getString(column_index_data);
int recordedVideoFileSize = cursor.getInt(column_index_size);
方案二:
The solution from Zelimir doesn't work in my case (the videos were at the right location but had a size of zero bytes). So i've found another solution:
protected void onActivityResult(int requestCode, int resultCode, Intent intent) {
super.onActivityResult(requestCode, resultCode, intent);
if (resultCode != RESULT_OK) return;
try {
AssetFileDescriptor videoAsset = getContentResolver().openAssetFileDescriptor(intent.getData(), "r");
FileInputStream fis = videoAsset.createInputStream();
File tmpFile = new File(Environment.getExternalStorageDirectory(),"VideoFile.3gp");
FileOutputStream fos = new FileOutputStream(tmpFile);
byte[] buf = new byte[1024];
int len;
while ((len = fis.read(buf)) > 0) {
fos.write(buf, 0, len);
}
fis.close();
fos.close();
} catch (IOException io_e) {
// TODO: handle error
}
}
The MediaStore.EXTRA_OUTPUT and the Uri aren't necessary in this case.
