• Batch process audio files and image files to create movie files by matching multiple wildcard values

  29 septembre 2022, par psychaudio

  I'm attempting to batch-process audio and image files to create video files using a Shell script with FFmpeg.

  


  

  1. The ffmpeg script works in Terminal :

  


  


  ffmpeg -loop 1 -i image.png -i audio.wav -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest output.mp4


  


  

  2. A nested for loop with wildcards works as a batch script :

  


  


  #!/bin/sh
for img in *.png; do
    for wav in *.wav; do
        ffmpeg -loop 1 -i $img -i $wav -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest ../mb/$img.mp4
    done
done


  


  The only problem here is that it creates more combinations than I need. I'd like to be able to match wildcard values and only mix those together. I'd like to be able to prepare the filenames to match in advance to make this easier : For example, only match 1.png with 1.wav to make 1.mp4, 2.png with 2.wav to make 2.mp4 and so on. I'm able to modify the script to match the wildcards in a Regex, but I'm not sure if there is a way to then execute the logic above. Here is what I am attempting :

  


  #!/bin/sh
img=*.png
wav=*.wav

if [[ ${img%.*} == ${wav%.*} ]];
    then
        ffmpeg -loop 1 -i $img -i $wav -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest $img.mp4;
    else
        echo "Failure"
    fi


  


  This begins by overwriting the image files, so it does not appear to work as planned. Is there a simpler way to do this ? Perhaps looping through images 1..5 in one folder and audio files 1..5 in another ?

  


  Thanks for any insights, and happy to provide more context (very new to this, so still learning).

  


• ffmpeg dont work in php shell_exec("ffmpeg -i $movie $pic &")

  26 septembre 2016, par josef

  I’m running the following script without any problems :

  <?php
  
  echo $video  = dirname(__FILE__)."\\MOVIES\\1.mp4";
  
  echo "<br />";
  
  echo $pic  = dirname(__FILE__)."\\PICTURES\\1.jpg";
  
  echo shell_exec("ffmpeg -i  $video  $pic &amp;");

  But when I run this one i get nothing :

  echo shell_exec("ffmpeg -i  C:\xampp\htdocs\Video-share-script\MOVIES\1.mp4  C:\xampp\htdocs\Video-share-script\PICTURES\1.jpg &");

  the value of $video is C :\xampp\htdocs\Video-share-script\MOVIES\1.mp4
  and $pic is C :\xampp\htdocs\Video-share-script\PICTURES\1.jpg
  thank you

• mobileFlash.check() for handling HTC Android + Flash 10.1, where flash does not load until on-screen (ie., in view.) If off-screen, positioned at left/top 0px in order to load (including scroll/resize if needed), then events released and movie moved off-screen. If in DOM already, flashLoadTimeout is set to 0 to allow infinite wait (eg., will not timeout and will load when scrolled into view.)
