when I used rosbag open bag file error "An error occurred when reading from the file."

When I run my experiment on the desktop computer the bag files can be opened in the MATLAB, but when I transfer the experiment to the laptop and get the bag files the error is reported ( "An error occurred when reading from the file." ) .

There is no Chinese in my file save path, and I tried other solutions to no avail.

clc,clear all
camera='Camera1';
type=0; %depth=0 / rgb=1;

filepath=fullfile('F:\ele_ladder\code\librealsense-master\librealsense-master\wrappers\python\examples',[camera,'.bag']);
bag=rosbag(filepath);

Command Window

An error occurred when reading from the file.
 
>> 

Cannot attach this file because:

• File:bag file.zip size exceeds 5 MB. Try compressing the image file in an archive format; for example, a zip file.

I dont konw why I can`t updata the bag file.

I solved this problem in Python because of the bag file. Bag file data collection is not standardized.

Reindex bag file in Python with linux.

$ rosbag reindex Camera1.bag

I have not found a good way to solve this problem in MATLAB.
