  • Librairies et logiciels spécifiques aux médias

    Pour un fonctionnement correct et optimal, plusieurs choses sont à prendre en considération.

  • No audio encoded with ffmpeg using webm/libvorbis

    15 mars 2013, par Craig Lillard

    Having issues getting audio to encode to webm. Tried many different methods and it just ain't happenin. The commands are printed below before each pass.

    I have tried moving the audio commands around, trying different bitrates, different audio commands and have tried it on a couple of different files as well that both have audio.

    Encoding these files to MP4 using x264 causes no problems and works just fine and the audio plays, so it appears to be an issue just with webm. As you can see below, it is a 2-pass encode.

    Thanks for any help you can provide !

  • FFMPEG overlay issue for 2 videos, sound missing from second input

    7 septembre 2014, par Abhishek Singh

    I’m trying to achive an overlay with ffmpeg wich take the two flv files as input and make a output and both videos playing simultaneously. things are working fine with below ffmpeg command :

    ffmpeg -i input1.flv -vf "[in] scale=359:320, pad=2*iw+6:ih [left]; movie=input2.flv, scale=359:320 [right]; [left][right] overlay=365:0 [out]" -b:v 3600k -y output.flv

    But issue is with the sound of second video and that is missing from the output.flv, only input1 sound is available in the output.flv.

    Console output is :

  • 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 :

    Am I completely missing something ? I'll keep trying, but will be very appreciative of any direction or assistance.
