  Fixes out of array access

• Weird commandline behaviour when running a batch script. Script will only work if another script is being run first [closed]

  31 décembre 2022, par Macster

  TLDR ;
  
In cmd.exe
  &#xA;makedir.bat only <= Not working
  &#xA;new.bat then makedir.bat <= Working

  &#xA;

  I'm new to batch and noticed a weird behaviour when running a scrip.

  &#xA;

  It basically takes the last entry(Video file path) from a textfile and uses the path inside a ffmpeg command to get the file duration. But it's not working. makedir.bat

  &#xA;

  What I know is that the part which gets the path is working on it's own, and so does the part that gets the duration.

  &#xA;

  Now, if I run a second script, new.bat, which is actually just the part that gets the files duration and outputs the right duration(22 Seconds), before running makedir.bat, suddenly makedir.bat starts working as intended, even though set /a duration=2*3600*60+*1 in the output is wrong. But thats only for cmd.exe. It wont work for PowerShell.&#xA;Whats going on ? Is the script faulty or is there some kind of caching in the cmd.exe ?

  &#xA;

  EDIT : Oh, and if I run makedir.bat first and then new.bat, new.bat wont work anymore.

  &#xA;

  makedir.bat

  &#xA;

  ::Get last entry from "mylist.txt"
for /f "delims=" %%a in ('type mylist.txt ^| findstr /b /c:"file"') do set path=%%a

::Trim path for file name
set video_path=%path:~32,-1%

echo %video_path%

::Get the video duration
for /f "tokens=1* delims=:" %%a in ('ffmpeg -i %video_path% 2^>^&1 ^| findstr "Duration"') do set duration=%%b

set duration=%duration:~0,12%
set /a duration=%duration:~1,2%*3600+%duration:~4,2%*60+%duration:~7,2%*1
echo %duration%


  &#xA;

  new.bat

  &#xA;

  for /F "tokens=1* delims=:" %%a in ('ffmpeg -i pipshort1.webm 2^>^&1 ^| findstr "Duration"') do set duration=%%b
set duration=%duration:~0,12%
set /a duration=%duration:~1,2%*3600+%duration:~4,2%*60+%duration:~7,2%*1


  &#xA;

  Ouput makedir.bat

  &#xA;

  >for /F "delims=" %a in ('type mylist.txt | findstr /b /c:"file"') do set path=%a

>set path=file '/webapp/stream/videos/pip/transparent_short.webm'

>set path=file '/webapp/stream/videos/pip/transparent_short.webm'

>set path=file '/webapp/stream/videos/pip/transparent_short.webm'

>set path=file '/webapp/stream/videos/pip/pipshort1.webm'

>set video_path=pipshort1.webm

>echo pipshort1.webm
pipshort1.webm

>for /F "tokens=1* delims=:" %a in ('ffmpeg -i pipshort1.webm 2>&1 | findstr "Duration"') do set duration=%b

>set duration=~0,12

>set /a duration=0,*3600+2*60+*1
Missing operator

>echo 0
0


  &#xA;

  Output new.bat + makedir.bat

  &#xA;

  >new.bat

>for /F "tokens=1* delims=:" %a in ('ffmpeg -i pipshort1.webm 2>&1 | findstr "Duration"') do set duration=%b

>set duration= 00:00:22.02, start: 0.000000, bitrate: 2337 kb/s

>set duration= 00:00:22.02

>set /a duration=00*3600+00*60+22*1

>echo 22
22

>makedir.bat

>for /F "delims=" %a in ('type mylist.txt | findstr /b /c:"file"') do set path=%a

>set path=file '/webapp/stream/videos/pip/transparent_short.webm'

>echo pipshort1.webm
pipshort1.webm

>for /F "tokens=1* delims=:" %a in ('ffmpeg -i pipshort1.webm 2>&1 | findstr "Duration"') do set duration=%b

  MAINTAINERS : some random updating
  Adding level to some of my entries
  
  Adding level to some random entries of other people who i have seen actively maintaining their code
  
  removing some people who have not been active where others where active
  For most we will need to contact people and ask if they are still available as maintainers
  
  (but for cases where patches are ignored for many months even with pings sent to the maintainer
  
   entries should be set to unmaintained)
