    9 août 2013, par Winnie Oldright

    Trying to convert f4v to mp4 with ffmpeg

    This file

    FFmpeg :

    ffmpeg -i input.f4v -vcodec copy -acodec copy output.mp4

    In output i have black screen in video and no sound but track seconds are incrementing properly.

    What i'm doing wrong ? Or maybe i need mpg or some other file type in out put (output file type should supports in android).

  • How to use (django-celery,RQ) worker to execute a video filetype conversion (ffmpeg) in django on heroku (My code works locally)

    15 janvier 2013, par GetItDone

    One part of my website includes a form that allows users to upload video. I use ffmpeg to convert the video to flv. My media and static files are stored on Amazon S3. I can get everything to work perfectly locally, however I can't seem to figure out how to use a worker to run the video conversion subprocess in production. I have dj-celery and rq installed in my app. The code in my view that I was able to get to work locally is :

    #views.py
    
def upload_broadcast(request):
    
    if request.method == 'POST':
    
        form = VideoUploadForm(request.POST, request.FILES)
    
        if form.is_valid():
    
            new_video=form.save()
    
            def convert_to_flv(video):
    
                filename = video.video_upload
    
                sourcefile = "%s%s" % (settings.MEDIA_ROOT, filename)
    
                flvfilename = "%s.flv" % video.id
    
                imagefilename = "%s.png" % video.id
    
                thumbnailfilename = "%svideos/flv/%s" % (settings.MEDIA_ROOT, imagefilename)
    
                targetfile = "%svideos/flv/%s" % (settings.MEDIA_ROOT, flvfilename)
    
                ffmpeg = "ffmpeg -i %s -acodec mp3 -ar 22050 -f flv -s 320x240 %s" % (sourcefile, targetfile)
    
                grabimage = "ffmpeg -y -i %s -vframes 1 -ss 00:00:02 -an -vcodec png -f rawvideo -s 320x240 %s" % (sourcefile, thumbnailfilename)
    
                print ("SOURCE: %s" % sourcefile)
    
                print ("TARGET: %s" % targetfile)
    
                print ("TARGET IMAGE: %s" % thumbnailfilename)
    
                print ("FFMPEG TASK CODE: %s" % ffmpeg)
    
                print ("IMAGE TASK CODE: %s" % grabimage)
    
                try:
    
                    ffmpegresult = subprocess.call(ffmpeg)
    
                    print "---------------FFMPEG---------------"
    
                    print ffmpegresult
    
                except:
    
                    print "Not working."
    
                try:
    
                    videothumbnail = subprocess.call(grabimage)
    
                    print "---------------IMAGE---------------"
    
                    print videothumbnail
    
                except:
    
                    print "Not working."
    
                video.flvfilename = flvfilename
    
                video.videothumbnail = imagefilename
    
                video.save()
    

    
            convert_to_flv(new_video)
    

    
            return HttpResponseRedirect('/video_list/')
    
    else:
    
...

    This is my first time trying to use a worker (or ever pushing a project to production), so even with the documentation it is still unclear to me what I need to do. I have tried several different things but nothing seems to work. Is there just a simple way to tell celery to run the ffmpegresult = subprocess.call(ffmpeg) ? Thanks in advance for any help or insight.

    NEWER EDIT

    I tried adding a tasks.py and added the task :

    celery = Celery('tasks', broker='redis://guest@localhost//')
    

    
@celery.task
    
def ffmpeg_task(video):
    
    converted_file = subprocess.call(video)
    
    return converted_file

    then I changed the relevant section of my view to :

    ...
    
try:
    
    ffmpeg_task.delay(ffmpeg)
    
    print "---------------FFMPEG---------------"
    
    print ffmpegresult
    
except:
    
    print "Not working."
    
...

    My new logs are :

  • 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))
    

    
                $i = 0;
    
                foreach($images as $image){
    

    
                    // REMOVE THE BACKGROUND IMAGE
    
                    if($behind){
    
                        $m->remove($behind);
    
                    }
    
                    // # REMOVE
    

    
                    // LOAD NEW IMAGE
    
                    $img = new SWFBitmap(fopen($image,"rb"));

                        $m->nextFrame();
    
                    }
    
                    $m->remove($pic);
    
                    // # 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);
