  • Amélioration de la version de base

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Menus personnalisés

    14 novembre 2010, par

    MediaSPIP utilise le plugin Menus pour gérer plusieurs menus configurables pour la navigation.
    Cela permet de laisser aux administrateurs de canaux la possibilité de configurer finement ces menus.
    Menus créés à l’initialisation du site
    Par défaut trois menus sont créés automatiquement à l’initialisation du site : Le menu principal ; Identifiant : barrenav ; Ce menu s’insère en général en haut de la page après le bloc d’entête, son identifiant le rend compatible avec les squelettes basés sur Zpip ; (...)

  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • FFmpeg avcodec_decode_video2 decode RTSP H264 HD-video packet to video picture with error

    29 mai 2018, par Nguyen Ba Thi

    I used FFmpeg library version 4.0 to have simple C++ program, in witch is a thread to receive RTSP H264 video data from IP-camera and display it in program window.

    Code of this thread is follow :

    DWORD WINAPI GrabbProcess(LPVOID lpParam)
    // Grabbing thread
    {
     DWORD i;
     int ret = 0, nPacket=0;

    When program receive RTSP H264 video data with resolution 704x576 then decoded video pictures are OK. When receive RTSP H264 HD-video data with resolution 1280x720 it look like that first video picture is decoded OK and then video pictures are decoded but always with some error.

    Please help me to fix this problem !

    Here is problems brief :
    I have an IP camera model HI3518E_50H10L_S39 (product of China).
    Camera can provide H264 video stream both at resolution 704x576 (with RTSP URI "rtsp ://192.168.1.18:554/user=admin_password=tlJwpbo6_channel=1_stream=1.sdp ?real_stream") or 1280x720 (with RTSP URI "rtsp ://192.168.1.18:554/user=admin_password=tlJwpbo6_channel=1_stream=0.sdp ?real_stream").
    Using FFplay utility I can access and display them with good picture quality.
    For testing of grabbing from this camera, I have a simple (above mentioned) program in VC-2005. In "Grabbing thread" program use FFmpeg library version 4.0 for opening camera RTSP stream, retrieve stream information, find the first video stream... and prepare some variables.
    Center of this thread is loop : Grab a frame (function av_read_frame) - Decode it if it’s video (function avcodec_decode_video2) - Convert to RGB format (function sws_scale) - Display to program window (GDI function SetDIBitsToDevice).
    When proram run with camera RTSP stream at resolution 704x576, I have good video picture. Here is a sample :
    704x576 sample
    When program run with camera RTSP stream at resolution 1280x720, first video picture is good :
    First good at res.1280x720
    but then not good :
    not good at res.1280x720
    Its seem to be my FFmpeg function call to avcodec_decode_video2 can’t fully decode certain packet for some reasons.

  • How to use ffmpeg to copy streams and preserve format and metadata ?

    24 septembre 2023, par dzeek

    I have two files with multiple streams in each.

    



    Output.mp4 has 2 streams : video and audio (streams 0,1)

    



    Input.mp4 has 3 streams : video, audio and data (streams 0,1,2)

    



    I need to add stream 2 from Input.mp4 to Output.mp4 yielding Final.mov.

    



    I tried using this command but it does seem to preserve the format and metadata for the stream that is added :

    



    ffmpeg -y -i Output.mp4 -i Input.mp4 -c copy -map 0:0 -map 0:1 -map 1:2 Final.mov


    



    The output from ffmpeg seems to show that it is working but the format and metadata for the streams in the Final.mov is not correct.

    



    I would appreciate any help with how to change the command to make it work.

    



    Thank you !

    



    Here is the command output :

    



    ffmpeg -y -i Output.mp4 -i Input.mp4 -c copy -map 0:0 -map 0:1 -map 1:2 Final.mov

  • How to keep transparency when scale webm file with ffmpeg

    5 octobre 2022, par Sonia Kidman

    I'm using ffmpeg to scale my WEBM file, by using below command : 
ffmpeg -i in.webm -c:v libvpx -vf scale=100:100 out.webm
The output has correct resolution as I expected but the problem is transparency become black background.

    



    Could someone give me a solution for this.

    



    Thank you so much.

    



    Below is the log of the operation :
