• Apostrophe issue with FFmpeg

  1er mars 2024, par Rohan Molinillo

  I'm working on a company's project which is vue.js.
There are also code parts in php.
It uses FFmpeg to create a video from multiple videos.
On each video, there is a text type subtitle.
Each text is retrieved from a .txt file
But I have a problem with apostrophes.

  


  If in the subtitle is stored like this ( I'm here ) in the txt file, on the video there will be written ( Im ).
The apostrophe is removed and the rest of the text too ( here ) will not be displayed.

  


  I'm new to php and ffmpeg, I've been on this problem for almost 3 weeks.

  


  I share the php code with you.

  


  <?php

  I tried many things but each time there were errors.
I think I didn't implement the code properly.

  


  I share you the error

• ffmpeg conversion executable file output ".MOD : no files in such directory"

  11 octobre 2023, par Zezaps

  I installed ffmpeg using Homebrew in macOS 12.2. I have a folder of MOD files from an old camera that I need to convert to MOV or MP4 to edit them, I have a .bat file in my Windows machine that I can run on a folder that has MOD files to batch convert them to MP4 or MOV that I can easily tweak but I'm kinda clueless with how to do this on my new (and first) Mac, I came across this script that I managed to use once through the terminal but tried putting it in a executable file so I can easily run it and copy it in every folder that I need to for new projects. When I created the exec file I'm not sure if I did it correctly though.

  


  for i in *.MOD;
  do name=`echo "$i" | cut -d'.' -f1`
  echo "$name"
  ffmpeg -i "$i" "${name}.MOV"
done


  


  This script is inside an exec file that I edited using TextEdit, it works sometimes if I go to the directory through the terminal and run it but if I run it double clicking it I get a ".MOD : Not such file or directory" even though I placed the exec on a folder that has multiple .MOD files.

  


  Here is the full terminal output
