• How to convert all new mp4 to a directory using ffmpeg ?

  11 août 2018, par Antonio Maycon

  What bash script can use to accomplish this task through ffmpeg ?

  I want my script to run as a loop and check if there are new mp4 videos in the directory.

  Afterwards, move the new files to another folder, if the file doesn’t exist there yet.

  If possible, I want to add a watermark to the video.

  I have the code to add more files. I want to include it next to the script that does the conversion of the new files.

  I created a bash file with the following data :

  #! /bin/bash
  
  
  
  srcExt=$1
  
  destExt=$2
  
  
  
  srcDir=$3
  
  destDir=$4
  
  
  
  opts=$5
  
  
  
  for filename in "$srcDir"/*.$srcExt; do
  
  
  
          basePath=${filename%.*}
  
          baseName=${basePath##*/}
  
  
  
  
  
          ffmpeg -i "$filename" $opts "$destDir"/"$baseName"."$destExt" -i logo.png -filter_complex overlay
  
  
  
  done
  
  
  
  echo "Conversion from ${srcExt} to ${destExt} complete!"

  Later i then run the file :

  ./ffmpeg-batch.sh mp4 mp4 /folder-source-file/ /folder-output-files/ '-ab 128k' 

• generate mpeg dash segments in specific directory using FFMPEG

  30 novembre 2023, par hegazy

  I need to generate mpeg dash mpd file and m4s chunks files for streaming which is working perfectly.

  


  The issue is the segments parts (.m4s files) generated in the app directory (ignoring the output .mpd file location) which restricted by the server, and any generated file should be generated only in specific location.

  


  so is there a way to specify the segments location using ffmpeg ?

  


• ffmpeg android, no such file or directory

  7 janvier 2014, par G.T.

  I have a problem using ffmpeg on android which I can't figure out what's the problem. I build a static ffmpeg, which I use as command line in android. Now my problem is that my code works fine and all for quite a few device, but for some reason on some device(like Nivo) it just fails.

  To be more precise it only fails when I use image as an input. My command has two -i input defined with a complex filter overlaying one on another. Now if I use two video it works like a charm. If I use an image as the second input then it fails saying :

  /mnt/sdcard/Pictures/picture_1389105356533.png : No such file or directory

  The file exists I checked it

  And to make it even more interesting this only happens on some device like the bloody Nivo, generally it works great ( Samsung s2, samsung s4, nexus 7, nexus 4 etc)

  Any idea ?
