Sometimes when recording videos, file size is 0kb (windows 10).

use subprocess by python, loop recording video with a 5-second interval in between，but some file size is 0kb. Has anyone meet this problem before？

file format: mkv

command：
start_record_command = f"scrcpy -s {device_id} --record={filepath} --record-format=mkv --time-limit={time_limit} --no-playback --no-window"

version: scrcpy 3.1

Reproduce on Windows 10 with scrcpy 3.1 using the supplied Python subprocess command, MKV output, and repeated 5-second recordings. Compare zero-byte files with successful recordings and trace the recording behavior to identify the failure; done means repeated recordings consistently produce valid non-empty files or the issue is clearly characterized.
