我的代码,
public static Bitmap retriveVideoFrameFromVideo(String videoPath) throws Throwable {
Bitmap bitmap = null;
MediaMetadataRetriever mediaMetadataRetriever = null;
try {
mediaMetadataRetriever = new MediaMetadataRetriever();
if (Build.VERSION.SDK_INT >= 14)
mediaMetadataRetriever.setDataSource(videoPath, new HashMap<String, String>());
else
mediaMetadataRetriever.setDataSource(videoPath);
// mediaMetadataRetriever.setDataSource(videoPath);
bitmap = mediaMetadataRetriever.getFrameAtTime();
} catch (Exception e) {
e.printStackTrace();
throw new Throwable(
"Exception in retriveVideoFrameFromVideo(String videoPath)"
+ e.getMessage());
} finally {
if (mediaMetadataRetriever != null) {
mediaMetadataRetriever.release();
}
}
return bitmap;
}
这是创建缩略图,但我用了很多时间ListView
然后ListView
挂断。
