如何使用 Video Uri 在 Android 上压缩视频

如何解决如何使用 Video Uri 在 Android 上压缩视频

我想压缩我的视频，然后将其上传到 firebase。但是如何使用 Uri 压缩视频，这里是我的上传活动代码，在这里我制作了一种将视频上传到 firebase 存储的方法，但我希望首先压缩视频，然后上传到 firebase。这里的任何人都请帮助我。

public class Upload_reels extends AppCompatActivity {
    private ImageView plus;
    private VideoView reelvideo;
    private EditText captiontxt;
    private Button uploadbtn;
    private RelativeLayout picktbtn;
    public static final int CODE = 12;
    private DatabaseReference reference;
    private FirebaseDatabase database;
    private FirebaseAuth firebaseAuth;
    private StorageReference storageReference;
    private FirebaseStorage firebaseStorage;
    private Uri videoUri;
    String profileUrl,tick,username,captionst,timestamp;
    private ProgressDialog progressDialog;
    String videoUrl,compressedUri;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_upload_reels);

        getSupportActionBar().hide();

        plus = findViewById(R.id.plusicon);
        reelvideo  = findViewById(R.id.reelPlay);
        captiontxt = findViewById(R.id.caption);
