FFMPEG not found error while attempting to implement ffmpeg into discord bot

How to concatenate 3 mp4 files using ffmpeg (facing error in resultant video) ?
5 février 2021, par Mayank ThapliyalI have 3 videos of mp4 format. They have same resolution (640 X 1280) but other properties like frame rate etc are different. I want to join them back to back.So I gave a check on internet and I used the following method


:: Create File List
echo file file1.mp4 > mylist.txt 
echo file file2.mp4 >> mylist.txt
echo file file3.mp4 >> mylist.txt

:: Concatenate Files
ffmpeg -f concat -i mylist.txt -c copy output.mp4


But unfortunately it did not worked.In the resultant video, file1 part got freezed, and audio of whole video shifted (no idea how).And other methods are also not working properly


I just want to join them back to back.Any idea how to do it ?


Edit :- I gave a check on the output of the ffmpeg (using pause command in bat and discovered the following. Maybe it may help regarding the issue)
