using output from mediainfo as variable in another command

So I'm trying to setup an easy way of starting videos with a bat file, and having that run Mediainfo first to get the length of the video so it can then stop vlc or whatever else when it's done playing. 

Complete name                            : C:\Users\Tyler\Desktop\Psych s05e11.mp4
Format                                   : MPEG-4
Format profile                           : Base Media
Codec ID                                 : isom (isom/iso2/avc1/mp41)
File size                                : 116 MiB
Duration                                 : 42 min 36 s
Overall bit rate                         : 382 kb/s
Writing application                      : Lavf55.13.102

That's the output from mediainfo I got in a txt file, I'm trying to just pull the 42 and the 36 from the duration bit and use it in another command. I should also add that these numbers have to be used separately. Thanks!

Edit: Thanks for replying everyone love the help; Here's what I'm trying to run now:

mediainfo.lnk --Language=raw --Output=General;%Duration% "C:\Users\Tyler\Desktop\Psych s05e11.mp4"

and the output is:

2556249

Now I need a way to take the first four digits and use them in a another command, somehow make 2556 a variable?

Using FOR /F

@echo off
for /f "delims=" %%a in ('mediainfo "--Output=General;%%Duration%%" "C:\Users\Tyler\Desktop\Psych\s05e11.mp4"') do set $Duration=%%a

Echo %$Duration%

Using a temporary file

@echo off
mediainfo.exe --Language=raw --Output=General;%%Duration%% "C:\Users\Tyler\Desktop\Psych s05e11.mp4" >out.txt  
set /p $Duration= <out.txt
set $Duration=%$Duration:~0,4%

echo Result = %$Duration%
del out.txt

Another way using @Jérôme Martinez [raw -output] idea. Without temporary file, using findstr :

@echo off
for /f "tokens=2 delims=:" %%a in ('mediainfo -f --Language=raw  "C:\Users\Tyler\Desktop\Psych s05e11.mp4" ^| findstr /i "duration"') do (
    set $Duration=%%a
    goto:next
)

:next
set $Duration=%$Duration:~1,4%
echo %$Duration%

Okay here's what I did finally, thanks for all the help!

C:\mediainfo\MediaInfo.exe --Language=raw --Output=General;%%Duration%% "C:\Users\Tyler\Desktop\Psych_s05e11.mp4" >out.txt  
set /p $Duration= <out.txt
set $Duration=%$Duration:~0,4%

echo Result = %$Duration%
del out.txt
pause

and the output is:

C:\mediainfo\MediaInfo.exe --Language=raw --Output=General;%Duration%    "C:\Users\Tyler\Desktop\Psych_s05e11.mp4" >out.txt 
set /p $Duration=  <out.txt 
set $Duration=2556 
echo Result = 2556 
Result = 2556
del out.txt 
pause
Press any key to continue . . .

took @echo off outta there so you could see it all

If you need the duration, use e.g. this command:

mediainfo "--Output=General;%Duration%" YourFileName.ext

In a general way, when you think to some automation, prefer to use e.g.:

mediainfo -f --Language=raw  YourFileName.ext

and select the lines which better fits your need, avoid fields with "/String" because they are intended only for display (not for automation).
