• Batch file runs on one folder and not the next [closed]

  9 novembre 2020, par user1738673

  Who Closed this question before it was resolved ?!? How can I get it reopened ?

  


  After all of the suggestions, here is the code to run in the folder of flac files :

  


  cd /D "%~dp0."

FOR %%# IN ("*.flac") DO (Title %~nx0 Processing: %%~nx#
                ffmpeg -i "%%~nx#" -ab 192k -map_metadata 0 -id3v2_version 3 "%%~n#.mp3")
                    
ECHO Completed %~nx0
PAUSE


  


  Here are my current troubleshooting steps as completed :

  


  I renamed the files in one of the folders in which it does not run to "a.flac", "b.flac", "c.flac", etc. That is to make sure it is not a filename related problem. It did not run.

  


  I renamed the folder itself to a single letter to make sure it was not a folder name issue (F :\MUSIC\j). It did not run.

  


  I copied the entire folder and gave it a new single-letter name (F :\MUSIC\y). It did not run.

  


  I copied the files to a newly-created single-letter named folder at the same directory level (F :\MUSIC\d). It did not work.

  


  I copied the flac files and bat file from the single-letter folder to a newly created single-letter folder. It did not run.

  


  So, I went back the original folder and RENAMED MY .bat FILE from single folder - flac to 192.bat to 192.bat. It ran perfectly.

  


  I went back and renamed the .bat file in all folders described above. They all ran perfectly.

  


  Next, I renamed my master .bat file to single_folder_flac_to_192.bat. I ran it in the original file folder with all of the original names for folder and files. It ran perfectly.

  


  I then copied it into each of the folder described above. It ran perfectly.

  


  I then went back to my original code and renamed it to 192a.bat. This still did not run in the original folder, but ran perfectly in the others I created.

  


  So, I renamed my original folder from 'F :\MUSIC\Yanni - Live At The Acropolis (1994) [FLAC]toylata`. It did not run.

  


  That is all I have time for before needing to go to work. More at lunch time.

  


  Original Post Starts Here :

  


  I am using Windows 10 Pro on my home PC.

  


  I have a batch file which uses ffmpeg to create mp3 from flac and then delete the flac. It runs perfectly in most folders of music. The code is here :

  


  FOR %%a IN ("*.flac") DO (Title %~0 Processing: %%~na.flac
            ffmpeg -i "%%~na.flac" -ab 192k -map_metadata 0 -id3v2_version 3 "%%~na.mp3"
            if not errorlevel 1 if exist "%%~pna.flac" del /q "%%~pna.flac")
ECHO Completed %~n0
PAUSE
                 


  


  In some folders, when I run the batch, it just blinks and goes away. Yes- there are flac files in the folders.

  


  I have checked the different music folders for their properties (read only, access, etc.) and they look identical. The file names are "normal". It doesn't matter which drive I copy the folder into, the results are the same.

  


  I have run the file as Administrator and get the same result.

  


  What else should I be looking into ?

  


• configure : improve non-pkgconfig Vulkan version check

  configure : improve non-pkgconfig Vulkan version check
  Check for the patch version as well as the major+minor version.
  The VK_API_VERSION macros are not usable in preprocessor code due
  
  to casts.
  
  The patch (header) version is meant to linearly increment and
  
  not be reset, however it's better to trust, but verify.

• Write empty packets into avi file ffmpeg

  26 avril 2022, par hagor

  A task :
I have a trusted video event detector. I trust to my event detector for 100% and I want to write an uncompressed frame to my avi containter only if my event detector produces "true" result.
For frames, when my event detector is producing "false" I would like to write an empty packet because I want to know that there was a frame without event happening.
Is it possible to keep AVI file alive ? Or do I need to write my own player in this case ?

  


  Another option is to calculate timestamps manually and set dts/pts to that calculated time.
Drawback : I will need to recalculate timestamps to understand how many frames were between events.

  


  I am using :

  


  


  av_write_frame(AVFormatContext, AVPacket) ;

  


  


  and

  


  


  av_interleaved_write_frame(AVFormatContext, AVPacket) ;

  


  


  What is your suggestion/idea ?
Thank you in advance.
