How can I fix Invalid data found when processing input error?

Before we start, make sure you have the latest version of FFmpeg installed. If you’re software that uses FFmpeg, update it to the latest version.

Make sure that you’re using the right command

1. If you need to use a text file, use the conact command like this: ffmpeg -f concat -i input.txt output.mp4
    
2. In case you don’t want to use concat, list the files in the command, like this: ffmpeg -i 1.mp4 -i 2.mp4
   
3. Add input options before input file, like this: ffmpeg -ar 48000 -ac 1 -f s16le -i step2.pcm step3.wav
   
4. Don’t forget to use the file keyword before the filename: file ./index9.ts
5. Also, try using  the following parameter as a workaround: --stop-at-time 3
