通过ContentResolver删除MediaLibrary文件引用：如何获取文件的ID？

Question

from this question I understand that if I want to remove a reference for a (video) file from the media library, I can do this:

Uri videoUri = MediaStore.Video.Media.EXTERNAL_CONTENT_URI;
Uri itemUri = ContentUris.withAppendedId(videoUri, mediaId);
getContentResolver().delete(itemUri, null, null);

what I miss is how to retrieve the mediaId .

For this file I have its path, filename, size, etc.

Any idea?
