v4.8.2

Bug Fix

• APP photos play video error.
• Correct MaixCAM-Pro pin image in photos APP.
• Fix set auto start APP failed in second time.
• Fix time sync script stuck when no network.
• Fix zbar can't decode Chinese issue.
• Fix open big file error in APP http file browser.

Optimization

Attention

Burning the system image, the following files in the assets folder:

• maixcam_*.img.xz: For the MaixCAM device.
• maixcam-pro_*.img.xz: For the MaixCAM-Pro device.
  Be careful not to burn the wrong image, as burning the wrong one may cause screen burn-in (it usually recovers slowly after being left for a period of time).
