  • Mediabox : ouvrir les images dans l’espace maximal pour l’utilisateur

    8 février 2011, par

    La visualisation des images est restreinte par la largeur accordée par le design du site (dépendant du thème utilisé). Elles sont donc visibles sous un format réduit. Afin de profiter de l’ensemble de la place disponible sur l’écran de l’utilisateur, il est possible d’ajouter une fonctionnalité d’affichage de l’image dans une boite multimedia apparaissant au dessus du reste du contenu.
    Pour ce faire il est nécessaire d’installer le plugin "Mediabox".

  • video after ffmpeg command conversion is not playing on windows

    10 décembre 2015, par Hemant Kumar

    I am stuck at a very weird and complex problem, hoping if anyone know the solution :

    I am converting user uploaded video using ffmpeg command on server and it was working fine as well. Today I found that if a video is recorded by a webcam from windows, is playing well in linux as well as on windows where as if user is creating a video by webcam from linux, is playing only on linux (any browser). On window it’s screen either show loading icon or black screen while audio is working fine.

    I am using following codec :

    ['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']

    I work on linux and using html5 player on my website. I am converting video in mp4 format.

    Input :

    ffmpeg -i /<server path="path">/stream_FE2AF05B-E630-1F7B-390B-37325B31B362.flv -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /<server path="path">/testing.mp4
    
</server></server>

  • Using ffmpeg for stream encryption by srtp in windows

    11 avril 2015, par user3248865

    I have been trying to make encrypted stream via ffmpeg and I´ve found srtp support in this library (ffmpeg documentation). Unfortunately, it seems that encryption doesn´t work at all. I´m using the following command to send stream :

    ffmpeg -re -i "output.mpg" -vcodec libx264 -f flv "srtp://192.168.0.100:7777?srtp_out_suite=AES_CM_128_HMAC_SHA1_80&amp;srtp_out_params=00108310518720928b30d38f41149351559761969b71d79f8218a39259a7"

    and this one for stream receiving :

    ffplay "srtp://192.168.0.100:7777?srtp_in_suite=AES_CM_128_HMAC_SHA1_80&amp;srtp_in_params=00108310518720928b30d38f41149351559761969b71d79f8218a39259a7"

    They work good.
    But, If I change the command for ffplay to this one :

    ffplay udp://192.168.0.100:7777

    it works too and I can watch the video. So, it means that encryption for srtp doesn´t work ?

    1. Is the stream encryption by using ffmpeg possible (not only srtp) ?
    2. If so, What am I doing wrong ?

    Thanks in advance.
