  • 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".

  • Convert images into video

    24 septembre 2017, par Disha Shukla

    I have some images in the folder. I want to convert all images into videos. But the problem is that when the resolution is different it shows the error. I don’t want to stretch the images in the video. I just want to keep image size as it is. But it shows this error.

    My Command :

    ffmpeg -framerate 1/3 -pattern_type glob -i "images/*.jpg" -i trinity.MP3 -shortest -c:v libx264 -r 30 -vf "scale=iw*sar:ih , pad=max(iw\,ih*(16/9)):ow/(16/9):(ow-iw)/2:(oh-ih)/2" -aspect 16:9 -pix_fmt yuv420p out.mp4 -y

  • 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&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&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.

    I have tried the above ffmpeg command with srtp_out_suite=NmcxMmQ2ZjVnYjEyNmRmMTV2czY1YWR2ZjFhc2Rm, but udp stream is still playing well.
