The.3gp file is generated on the xiaomi phone.

What is the reason for the.3gp file generated when I use xiaomi android phone?
Here is my code:

Thank you very much !

The issue mentions a Xiaomi Android phone and includes an image of the code, but names no repository file, test, or entry point. Start by reproducing the media operation on the reported device and inspect the Android media path; done would require identifying why the .3gp file is created and documenting or correcting that behavior.
