Video scaling issue on Android 7.0 in Media3 (version 1.4.0)

Hello AndroidX.media3 team,

I've encountered an issue related to video scaling on a device running Android 7.0, using the Media3 library version 1.4.0.

In the demo application, I've added two buttons that scale the PlayerView to specific dimensions:

- scale(187, 684, 384, 216) – scaling to custom dimensions

scale(0, 0, 0, 0)– returning to fullscreen Here is the code used for scaling:

`void scale(int x, int y, int w, int h) {
  Log.d("TEST", "scale to following coordinates[" + x + ", " + y + ", " + w + ", " + h + "].");
  if (playerView == null) {
    Log.d("TEST", "surfaceView is null, cannot scale the player.");
  } else {
    final ViewGroup.LayoutParams params = playerView.getLayoutParams();
    if (params == null) {
      Log.d("TEST", "surfaceView has no layoutParams, cannot scale the player.");
    } else {
      params.width = w == 0 ? ViewGroup.LayoutParams.MATCH_PARENT : w;
      params.height = h == 0 ? ViewGroup.LayoutParams.MATCH_PARENT : h;
      playerView.setX(x);
      playerView.setY(y);
      this.runOnUiThread(() -> {
        playerView.setLayoutParams(params);
      `});`
    }
  }
}`

The issue is as follows: while the PlayerView correctly changes its size and position, the video continues to play at its initial size (fullscreen) without adapting to the new layout. This problem occurs only on Android 7.0. On newer versions of Android (8.0, 11, 12), the scaling works as expected.

I also tried manually switching the video tracks to a lower resolution. This worked only if the player was not paused (i.e., exoPlayer.setPlayWhenReady(true); was set).

I've attached a log from the application and two video recordings to illustrate the issue:
