• How to QUICKLY batch scan video files to check for integrity (corrupt / valid)

  9 juillet 2024, par nhershy

  This question has been asked several times on this forum, with the accepted answer using ffmpeg to assess the integrity of the file with these example commands :

  


  # scan a single file
ffmpeg.exe -v error -i C:\to\path\file.avi -f null - >error.log 2>&1

# batch scan
find C:\to\path\ -name "*.mp4" -exec sh -c "ffmpeg -v error -i '{}' -map 0:1 -f null - 2>'{}.log'" \;


  


  The Problem :

  


  The above commands work without issue, taking anywhere between 2-20 mins to assess a single video file. But when running the above batch command on a large number of video files (1000+) (assuming an average of 5 minutes per file), the process could take over a week to finish.

  


  The Objective :

  


  Looking for a faster solution to verify integrity of my files. Either to modify the ffmpeg command, or to use as a different binary entirely. Anything is accepted as long as I can run the new command in the terminal/bash. Would like to get the processing time down from a few days, to a few hours.

  Update

  


  I never did find a "quick" way of scanning the video files. I just accepted that for the sake of thoroughness it will take some time. However, I made a GUI Python program that may benefit others :

  Il n’a pas de saut de ligne entre chaque description de champ, et du coup, la preg_match() de l’échappement des textes entre guillemets obtenait un résultat différent (par défaut preg_match s’arrête à chaque saut de ligne mais là il n’y en a pas). L’échappement ne créait qu’un élément dans cet exemple (...)

• How to Write .ts file using AVAssetWriter in Swift Package Manager (Executable)

  26 décembre 2022, par Saravana

  I will able to record the screen in Mac-OS using AVAssetWriter with mp4 format. But that mp4 file is not playing the HLS player.

  


  As per my research HLS player supports only .ts, so i tired to convert .mp4 to .ts file using ffmpeg, but that ffmpge framework is not working in Package.Swift Executable export. Is there any way to write .ts file format without using any framework or any other file type that would support HLS player.
