  • ffmpeg : Pipe input error

    1er septembre 2012, par Amit Khanna

    I'm facing an issue while working with ffmpeg when input and output are pipes. Though Output pipe is working fine, piping the input is causing some error.

    I tried to convert mp4 video to flv using the following command and it worked fine :

    $ ffmpeg  -i video-2012-04-26-19-48-40.mp4 -ar 44100 -ab 96 -f flv pipe:1 | cat> videoname.flv

    It worked fine and gave the following output :

  • Perl FFMpeg print output

    31 janvier 2012, par user346443

    Hi im using the following perl command to convert files with ffmpeg :

    system ("/usr/local/bin/ffmpeg -i $inputFile $outputFile");

    I would like to know if its possible to print the ffmpeg output ?

    Cheers

    UPDATE

    The solution was to use backticks

    my $output = qx{/usr/local/bin/ffmpeg -i $inputFile $outputFile 2>&1};
    
print $output

    This prints out the following :

  • Unable to execute CLI commands through PHP

    13 janvier 2012, par user940154

    OS : ubuntu 11.10
    Webserver : Apache
    Code : PHP
    I am trying to display the output of command "ffmpeg -i " on the webpage using php.
    Required : The webpage should show the information about video (text).
    Whats happening : The webpage shows no text output on running the php code.
    If I was however doing system("ls") the code runs fine and outputs the list of files.
    Here's my code

    <?php
    
 echo "Details of video file:";
    
 system('ffmpeg -i /home/atish/Videos/T2V0040006_Angled_ride_720x576i_FLDCMB.avi');
    
?>

    The same command works fine on my shell, and my system has ffmpeg installed. Here's a snapshot of executing this command directly on shell :

    I have tried appending "DISPLAY=:0" to my command and also done "xhost +" before running php code, but nothing is helping me out.

    Thanks.
