  • FFmpeg "Could not open file" error message when processing with PHP

    26 octobre 2015, par FlyingCat

    I am using ffmpeg to get the image from several video files. I got my ffmpeg codes ready but I got the following error when I exec my codes.

    ffmpeg version 0.8.6-4:0.8.6-0ubuntu0.12.04.1, Copyright (c) 2000-2013 the Libav developers

av_interleaved_write_frame(): Input/output error

    I only show the error messages that have color highlighted.
    My code :

     $ffmpeg ="/usr/bin/ffmpeg";
    

    
 $image_source_path = '/test/project/test.mp4';
    
 $ALL_PLACE_WIDTH = 300;
    
 $ALL_PLACE_HEIGHT = 300;
    

    
 $image_cmd = " -r 1 -ss 00:00:10 -t 00:00:01 -s ".$ALL_PLACE_WIDTH."x".$ALL_PLACE_HEIGHT."   -f image2 " ;
    

    
 $dest_image_path = '/test/project';
    

    
 $str_command= $ffmpeg  ." -i " . $image_source_path . $image_cmd .$dest_image_path;
    
 shell_exec($str_command);

    It seems my Linux wants to me to switch to avconv. I am not sure how to fix these errors. Can someone give me a hint about it ?
