  • PHP - Problems running ffmpeg.exe with shell_exec on Windows

    30 septembre 2012, par King

    I am trying to encode an FLV file to MP4 with ffmpeg.exe, its all working fine when running the code on the commandprompt (I have tried simply echoing the command and pasting it into the cmdline)

    Note : Using windows.

    Here is the code :
    it does not return anything, and does not encode anything, there are no errors, nothing happens :(, system($cmd, $returnval) returns 1 that's all
    running commands like dir works fine, so I have the required access.

    <?php
    
$title = $_GET['file'];
    
// encoding command > , below shows info "flv/'.$title.'.flv" "mp4/'.$title.'.mp4"
    
$cmd = ('cd C:/inetpub/wwwroot/run/ && ffmpeg.exe -i "flv/'.$title.'.flv"');
    
$ll = system($cmd, $fv);
    
echo "CMD: $cmd \nFull output: $fv \nLL = $ll";
    
?>

    ffmpeg.exe -h will return the help text, I am starting to wonder if it could have something to do with the other outputs having colours in them ?

    Any ideas ? :O

    (The cd is not the problem because $cmd = ('cd C:/inetpub/wwwroot/run/ && ffmpeg.exe -h'); works fine, its actually already in that directory)

  • Using ffmpeg to play file on windows, should use directshow to render the decoded frame [on hold]

    22 juillet 2013, par Terry

    I want to write a video file player using ffmpeg(support many format).

    However ffmpeg(/ffplay.exe) using SDL to render the video frame and play the audio sound. I only want to support windows platform. I think the default windows technology/api is more suitalbe for me to render the decoded frame. Do you think so ?

    If so, should I use direct show, or just using direct draw for video frame and direct sound for audio frame.

    If using direct show, I think I need to wrapper a direct show source filter(/splitter), then pass down the decoded video/audio frame data to render filter.

    Please help me which is the best choice ?
