Invalid data found when processing input. No start code is found

I am trying to concat video from many files. But sometimes I receive an error: "Invalid data found when processing input".

So, I am trying to iterate over files with ffprobe and find invalid files. Here is the error.

ffprobe started on 2020-06-28 at 16:06:39

Rec496_20200423123337_A_1.avi: Invalid data found when processing input

Questions:

  1. How can this be fixed, so I don't need to iterate with ffprobe and just use concat (command line: f:\prog\ffmpeg\bin\ffmpeg.exe -f concat -safe 0 -i mylist.txt -c copy output-xx.avi)?
  2. If not, how can I receive an error in my .bat file and move "invalid" file to "Error" folder?

Ok, here is the solution for .bat file. It moves file to "Err" folder, if found word "Invalid" in log.

set FFREPORT=file=ffreport.log:level=32

IF NOT EXIST "err" md err

for %%i in (*.avi) do (
f:\prog\ffmpeg\bin\ffprobe.exe -i %%i 
echo 'errlevel:' + %ERRORLEVEL% >> err.txt  

find /c "Invalid" ffreport.log && ( move %%i err )

type ffreport.log >> err.txt  
)
