  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • 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 : audio + image to video : reduce time and space it takes

    9 septembre 2019, par Yashasvi

    I am using FFMPEG to convert an image and an audio to a video.

    I am able to achieve the final video using the following command (Attaching the output of the command too) :

    time ffmpeg -loop 1 -i inputImage.jpg -i inputAudio.mp3 -c:v libx264 -
    
c:a copy -shortest output1.mp4

    Here are the respected sizes of inputs and output :

    inputImage.jpg : 160kb

    inputAudio.mp3 : 380.3kb

    output1.mp4 : 1.3MB

    The size of output video is pretty large as compared to the input audio. This is my first issue.

    Secondly, as you can see, this process takes 30sec, which is too much I think.

    How do I solve this two problems ?

    • reducing the output video file size

    • reducing the time this process takes.

    I’ve gone through numerous online links, including a lot of questions on this forum for the past several hours but still not able to solve this.
    Tried playing with framerate but disturbs the duration of the output video.

    Can someone please help here. Let me know if any other information is needed.

    1 thing that helped me reduce the size of final video from 3MB to 1.2MB was to compress the image that I am using.

  • ffmpeg error : Too large number of skipped frames xxxxx > 60000

    16 septembre 2019, par Fulkron

    I try to record on RasperryPI from usb Cam (/dev/video0) using segments to obtain sliced video.
    The command I’m using is :

    ffmpeg -input_format mjpeg -video_size 640x480 -i /dev/video0 -y -y -f v4l2 -an -pix_fmt yuv420p -codec copy -f segment -segment_time 60 -segment_wrap 10 -t 180 stream/looper%02d.avi

    I got an error after 2 minutes about skipped frames (see later for detail).
    Is I run the same command without segmentation is working.

    I tested on different HW, with different segment parameters, with different usb cam but the situation still the same.

    Here there is the output :
