how to export frames from multiple video files

[Vano333]

while I just came up with such a design with export to different folders
therefore export to one folder deletes previous files
and the asterisk substitution command does not work
--input-file "%WORKSPACE%\data_src*.*

png and jpg only for test

file 2) extract images from ALL video data_src.bat

@echo off
call _internal\setenv.bat

"%PYTHON_EXECUTABLE%" "%DFL_ROOT%\main.py" videoed extract-video ^
--input-file "%WORKSPACE%\data_src_1.mp4" ^
--output-dir "%WORKSPACE%\data_src_video_export1" ^
--output-ext "jpg" ^
--fps 0

"%PYTHON_EXECUTABLE%" "%DFL_ROOT%\main.py" videoed extract-video ^
--input-file "%WORKSPACE%\data_src_2.mp4" ^
--output-dir "%WORKSPACE%\data_src_video_export2" ^
--output-ext "png" ^
--fps 0
pause
