Extremely slow video selection with MOV format on iOS devices and Simulator

Description

Video selection is extremely slow (10-30+ seconds) when picking MOV format videos on iOS (both physical devices and Simulator) using image_picker. The same videos load instantly with file_picker. This issue does not occur on Android devices.

Steps to Reproduce

1. Use image_picker to pick a video from gallery on iOS (device or Simulator)
2. Select a video in MOV format (typically recorded with iPhone camera)
3. Observe the loading time

Code sample:

import 'package:image_picker/image_picker.dart';

final ImagePicker picker = ImagePicker();
final XFile? video = await picker.pickVideo(
  source: ImageSource.gallery,
);
// Takes 10-30+ seconds to return on iOS with MOV files

Expected results

• Video selection should complete within 1-2 seconds
• User should be able to select MOV format videos without noticeable delay
• Performance should be consistent across platforms
• The behavior should match file_picker package performance with the same MOV files

Actual results

• Video selection takes 10-30+ seconds when picking MOV format videos on iOS
• The app appears frozen/unresponsive during this time with no loading indicator
• iOS Simulator: Same delay issue (10-30+ seconds)
• Physical iOS devices: Same delay issue (10-30+ seconds)
• Android devices: Works fine, no delay
• Same MOV files with file_picker: Loads instantly (under 1 second)

Code sample

import 'package:image_picker/image_picker.dart';

final ImagePicker picker = ImagePicker();
final XFile? video = await picker.pickVideo(
  source: ImageSource.gallery,
);
// Takes 10-30+ seconds to return on iOS with MOV files

Comparison with file_picker

The same MOV files can be selected instantly (< 1 second) using the file_picker package, suggesting this might be related to how image_picker processes or validates video files on iOS.
