  • FFMPEG - Not finding codec parameters

    26 février 2016, par Tanner Smith

    I’m trying to convert a sequence of images into a mpeg movie via FFMPEG, although I keep getting an error saying that it could not find the code parameters (Video : mjpeg). A Google search did not bring much up that was useful.

  • php ming flash swf slideshow to mp4/avi

    19 août 2013, par Stefan

    After hours of searching and trying i finally got a nice script together that generates a good looking Flash .swf file with a nice transaction in between de images.
    It works great if you access the swf file directly in a browser, depending on the amount of images the flash created takes anywhere between 10 and 60 seconds.
    But when uploading to Youtube the movie created flashed by in one second.
    Because swf isnt really a accepted fileformat for Youtube we decided to convert the flash file to mp4 or avi using ffmpeg.
    Unfortunally that didnt work, it had the same effect as the youtube movie.
    We had a old version of ffmpeg and updated that to a recent version and tried to convert again with the same result.
    The main thing i see is that ffmpeg cant see the swf file duration and bitrate, they are both 'N/A' while were do set them in the php script.
    I thought it looked like the Metadata doesnt get written and i cant find anything on that regarding Ming.
    But i downloaded a phpclass that extracts the metadata from the swf and that tells me the framerate etc is getting set.

    Now i have to admit i havent really tested with the new version because the commandline options are a little different but ill work on that after i post this.
    In the previous version we tried setting the framerate of the source swf file, but that didnt work either.

    Anyone here that can has a idea ? it would be greatly appriciated.

    PHP Ming Script :

          $fps = 30;
    
         foreach($objects as $objectId => $images){
    
                // START FLASH MOVIE
    
                $m = new SWFMovie();
    
                $m->setDimension($width, $height);
    
                $m->setBackground(0, 0, 0);
    
                $m->setRate($fps);
    
                $m->setFrames(count($images)*202); //count(images)* 2 breaks *($fps*$breakTime)+22(fadeOut))

                    if($behind){

                    // # BREAK
    

    
                    // LOAD THE NEXT IMAGE AS BACKGROUND, IF LAST IMAGE, LOAD FIRST
    
                    $nextBackgrondImage =($images[$i+1]) ? $images[$i+1] : $images[0] ;
    
                    $img = new SWFBitmap(fopen($nextBackgrondImage,"rb"));
    
                    $behind = $m->add($img);
    
                    $behind->setdepth(2);
    
                    // # LOAD
    

    
                    // AND FADE OUT AGAIN
    
                    $img = fadeOut($image, $width, $height);
    
                    $pic = $m->add($img);
    
                    $pic->setdepth(3);
