• ffmpeg and php does not end the conversion

  23 juin 2016, par Fernand Royale

  I’m going crazy with it and do not think the solution.

  I use this code to convert videos, but the conversion did not terminate. I tried several times and stops at different points.

  echo "Starting ffmpeg...\n\n".'';
  
  echo shell_exec('/usr/src/ffmpeg/ffmpeg/ffmpeg -y -i movie.mp4 -i logo.png -filter_complex "overlay=10:10" -b:v 1500k -vcodec libx264 movie2.mp4 2> out.txt').'';  
  
  echo "Done.\n";

  Output from ffmpeg :

• ffmpeg throw a silent video output when trying to merge video and audio

  31 janvier 2023, par porororo

  I tried to combine mp4 format video and wav format audio.
The video is shorter than the audio and start second is same as 00:00.

  


  I used command as bellows :

  


  ffmpeg -i video.mp4 -i audio.wav  -filter_complex "[0:a]volume=0.2[A];[1:a][A]amerge[Aout]" -map 0:v -map [Aout] -y -shortest output_video.mp4


  


  The problem is the output_video.mp4 is a silent video without the sound.

  


  How can I get the output_video.mp4 with sound from audio.wav ?

  


  ffmpeg output is :

• Create 1 video using image with length of audio

  19 septembre 2017, par Vishnu

  I am trying to create video with the length of an audio file , and 1 single image as the background for whole video.

  I use following code

  'ffmpeg -y -loop 1 -f image2 -r 24 -i subtitle.jpg  -i audio.mp3 -c:v libx264 -c:a copy -shortest video.flv';

  But problem is processing time is too slow , and sometime video length is not same as audio length.Can some one suggest me alternative ideas.

  p.s : audio length is just 3 to 8 seconds.

  Below is my output
