FFmpeg does not convert file through command line

[Vidikon]

Hello, I have an issue where ffmpeg does not convert an appropriate file for a webserver.

Here's the setup: we are running a video webserver via xampp hosting a file that is continuously renewed by a command line loop.

1. The loop takes from an old TVT-CMS software that continously makes .dat files.
2. The loop moves them to the "hova" folder and moves around other files (deleting old files) before finally moving them to a "konvert" folder.
3. Here ffmpeg is ran to convert the file into a widely-compatible .mp4 file. This is where my problem is.
4. Once the .mp4 file is converted, it is done. The webserver refers to it and the video is accessible.

Sample file:
https://drive.google.com/open?id=1GmKw4usndKt4QLxPMU7amY9WmfLCqf2n

Here are the command lines:

The initiator and looping command:

rem @echo off
set konyvtar=C:\RecData79fc08a97cef4cb781f20b515debcac 7\
set kam1=0018ae3f302400
set kam1_dat=@
set hova=c:\xampp\htdocs\kamera\vid\honnan
set tid=
set kam1_time=0

call torol.bat %konyvtar%%kam1%
rem töröljük a nem szükséges videókat
for /f "skip=3" %%G IN ('dir /b /a-d /o-d "%konyvtar%%kam1%"') DO del %konyvtar%%kam1%\%%G

for /F "tokens=2 delims= " %%A IN ('tasklist /FI ^"imagename eq cmd.exe^" /NH ') DO (
set tid=%%A
goto again
)

rem timeout /t 30
:again
set /A cou=1
:loop
echo %cou%
ping 1.1.1.1 -n 1 -w 6000 > nul
rem timeout /t %kam1_time%
del /F %hova%\*.dat
set line=
for /f "skip=1" %%G IN ('dir /b /a-d /o-d "%konyvtar%%kam1%"') DO if not defined line set "line=%%G"
rem pause
if %kam1_dat% neq %line% (
set "kam1_dat=%line%"
start konvert-576p.bat %konyvtar%%kam1%\%line% %hova% %line% kam1
set kam1_time=6
)
timeout /t 30
if %cou%==300 (
call taskkill /F /IM cmd.exe /FI ^"PID ne %tid%^" /T
timeout /t 12
for /R "c:\xampp\htdocs\kamera\vid\VirtualDub\" %%I IN ("vdsub.zip") DO (
"c:\Program Files\7-Zip\7z.exe" x -y -o"%%~dpI" "%%~fI"
)
for /f "skip=3" %%G IN ('dir /b /a-d /o-d "%konyvtar%%kam1%"') DO del %konyvtar%%kam1%\%%G
goto again
) ELSE (
set /A cou+=1
goto loop
)
timeout /t 30

The converter file:

copy /Y %1 %2
set gg=%3
set mit=%gg:~0,14%
vid\ff\bin\ffmpeg -f h264 -y -t 00:01:00 -i vid\honnan\%mit%.dat -s 1280x720 -fs 50000000 -preset ultrafast -report %2\%4.mp4
move %2\%4.mp4 vid\konvert
del /F vid\honnan\%mit%.*
rem pause
exit

This is the ffmpeg report:

Bolding is mine.

In the past, this command line worked. Then the server machine died and has been replaced. I have managed to restore the original conditions as much as possible.

I am also open to using another program that could monitor an IPC camera and make a continuously refreshed .mp4 file through other methods. Ideally, it should be winXP compatible but I am willing to upgrade to windows 7 if it gurantees that it works.

Insert these lines after the call to FFmpeg in the converter script.

echo ****************
dir %mit%
echo ****************
exit /b

If it says "File not found" (in Hungarian, I presume), then you have to figure out why the input file is not being created.

Yes, it writes out that the file is not found. Which is strange because the batch file starts out by telling me that it has successfully copied out the necessary file. Then the two set commands (gg and mit) then ffmpeg starts. Then the file somehow disappears for ffmpeg and the echo commands you told me to add tells me that the files are not found. The file even disappears if I manually copy it to the "honnan" directory.

What am I doing wrong?
