• Findstr for multiple string patterns matching text batch or bash output in ffmpeg [duplicate]

  24 novembre 2020, par code0001

  I have a single audio only file for example “green_yellow_red.mp3”.
I have also various mp4 videos without audio with different names for example red_blue_green.mp4 pink_yellow_red.mp4 blue_red.mp4
  
The number of color strings can vary from 1 to 10. I want to output a list of videos that match at least one color string of the mp3 file and output it on a text. I want to do this for one mp3 among all the videos…And also for all mp3 against all mp4s for batch processing. I can only make list of all videos like this for now. (for %%i in (*.mp4) do @echo file '%%i') > mylist.txt
Please help me. Thank you.
P.S the color code is for description only. You can use your own naming method if the scripting would be easier in another naming system.

  lavf/url : fix relative url parsing when the query string or fragment has a colon
  This disallows the usage of ? and # in libavformat specific scheme options
  
  (e.g. subfile,,start,32815239,end,0,,:video.ts) but this change was considered
  
  acceptable.

• Subtract a specific string from a variable in a for loop

  14 octobre 2020, par Filip

  I am making a file converter with batch using FFMPEG.

  


  I have encountered a problem when trying to subtract the name of a file from the complete link to the file to get the directory of the folder it is in so after the file is converted it can be put into that directory.

  


  Can someone advise me on how I could subtract the string from the filename variable from the string in the directory

  


  My code :

  


  @echo off
SETLOCAL ENABLEDELAYEDEXPANSION
set filetype=.flac
for /R %%a in ("*%filetype%*") do (
    set directory=%%a
    set filename=%%~na%filetype%
    set convdir=!directory:%filename%=!
    echo !convdir!
    pause
    ffmpeg -i "%%a" "convdir%%~na.wav"
    echo Converted %%a
)
echo Convertion Done!
pause
