  • Librairies et binaires spécifiques au traitement vidéo et sonore

    31 janvier 2010, par

    Les logiciels et librairies suivantes sont utilisées par SPIPmotion d’une manière ou d’une autre.
    Binaires obligatoires FFMpeg : encodeur principal, permet de transcoder presque tous les types de fichiers vidéo et sonores dans les formats lisibles sur Internet. CF ce tutoriel pour son installation ; Oggz-tools : outils d’inspection de fichiers ogg ; Mediainfo : récupération d’informations depuis la plupart des formats vidéos et sonores ;

  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • FFMPEG - Zoompan image overlay keep ratio

    4 mai 2018, par Pier Giorgio Misley

    With zoompan I can zoom in and out an image overlayed over a video. My problem is that the image ratio is not respected and the image is stretched in something like 16:9

    The image in the center is a phone vertical picture, but It result like this : this

    Looks like zoompan is trying to stretch to full width and the height to.. something. How can I keep the ratio while zooming ? I tried using sar but it doesn’t work

    Note : I read this post and I probably should set the size, but how can I set it to keep the original one ?

    Edit :

    -i "vid.mov" -loop 1 -t 1 -i "1.png" -filter_complex "[1:v]format=rgba,scale=1440x2560,setsar=1/1,zoompan=z='min(zoom+0.0015,1.5)':s=720x1280:d=7250:x='iw/2-(iw/zoom/2)':y='ih/2-(ih/zoom/2)',fade=in:st=20:d=1:alpha=1,fade=out:st=77:d=1:alpha=1[im];[0][im]overlay=(main_w-overlay_w)/2:(main_h - overlay_h)/2:shortest=1" -pix_fmt yuv420p -c:a copy output_0.mp4

    With this, in some video format/resolutions it works, in others not

    ie : with .mp4 it works, with .mov it doesn’t

  • FFMPEG : RTSP re-stream dies randomly

    14 mai 2018, par stevendesu

    I have a security camera streaming RTSP, and I wish to re-stream this to an RTMP ingest server. For now I’m using my laptop as an ffmpeg proxy, but eventually I’ll use a raspberry pi or something similar (cheap/small)

    Here’s the command I’m using (pretty simple) :

    ffmpeg -i rtsp://@10.0.0.16:554/1/h264major -c:v libx264 -c:a none -f flv rtmp://output/camera_stream

    This works but after a minute or two the stream dies. Here’s the output :

    The camera is pretty cheap (from China) so it’s likely I’m getting bad data from it or it’s cutting out for a few seconds at a time. Ideally I would need ffmpeg to handle this well (ignore bad data, wait as long as necessary for good data to resume encoding)

    Using ffplay to check out the RTSP stream, I get output like the following :

    Then eventually the video just freezes. The first time it froze after around 5 minutes, but I wasn’t able to say definitively if it froze the instant 44 packets were dropped or if it froze randomly later. So the second time I stared intently.... for 21 minutes. Then I got bored of it not freezing, turned to pet my cat, and when I looked back 15 seconds later it was frozen. I think it only breaks when no one is watching it.

    What I can say definitively is :

    • While running normally, M-V hovers around 0 (anywhere between -0.01 and +0.01)
    • Once frozen, M-V begins to count down into negative numbers without stopping - although at a rate slower than -1 per second
    • While running normally, aq is 0KB and vq is a positive number (I think it was 30KB or so ?)
    • Once frozen, vq is also 0KB

    It’s a really cheap camera with a crummy power supply that goes out if you breathe on it, so it’s likely the camera is going temporarily offline during this time — but I’d like ffmpeg to wait out a timeout and resume streaming when it sees the camera again.
