How to reproduce?

1. Implement manage_photo to select a video.
2. Use video_player to playback selected video.

Note: Green color tint issue not present using image_picker. Results were the same even after trying filterQuality and gaplessplayback settings. I disabled all theming in my app and still had the tint issue.

Logs

Example code (optional)

final PermissionState ps = await PhotoManager.requestPermissionExtend();
      if (!ps.isAuth) {
        if (!mounted) return;
        ScaffoldMessenger.of(
          context,
        ).showSnackBar(const SnackBar(content: Text('Gallery access denied')));
        return;
      }

      // Fetch all video assets
      final List<AssetPathEntity> albums = await PhotoManager.getAssetPathList(
        onlyAll: true,
        type: RequestType.video,
      );

      if (albums.isEmpty) return;

      final List<AssetEntity> videos = await albums.first.getAssetListPaged(
        page: 0,
        size: 100, // Fetch first 100 videos
      );

      if (videos.isEmpty) return;

      // Present a simple selection dialog
      AssetEntity? selectedVideo = await showDialog<AssetEntity>(
        context: context,
        builder: (context) {
          return SimpleDialog(
            title: const Text('Select a Video'),
            children: videos.map((v) {
              return SimpleDialogOption(
                onPressed: () => Navigator.pop(context, v),
                child: FutureBuilder<Uint8List?>(

                            fit: BoxFit.cover,
                          )
                        else
                          Container(width: 64, height: 64, color: Colors.grey),
                        const SizedBox(width: 8),
                        Expanded(child: Text(v.title ?? 'Video')),
                      ],
                    );
                  },
                ),
              );
            }).toList(),
          );
        },
      );

      if (selectedVideo == null) return;

      final file = await selectedVideo.file;
      if (file == null || !await file.exists()) {
        ScaffoldMessenger.of(context).showSnackBar(
          const SnackBar(content: Text('Selected file not found.')),
        );
        return;
      }

      print('[DEBUG] _pickVideoFromGallery: file path ${file.path}');

      await _handleSelectedVideo(file);

// _handleSelectedVideo method pseudocode:

1) navigates user to video screen with file
2) video player plays video (no re-encoding)

AI Summary: The user reports a green color tint issue when playing videos selected using photo_manager with video_player on iOS, but not with image_picker.

This should be a problem with the video_player regarding decoding.
