  • Script d’installation automatique de MediaSPIP

    25 avril 2011, par

    Afin de palier aux difficultés d’installation dues principalement aux dépendances logicielles coté serveur, un script d’installation "tout en un" en bash a été créé afin de faciliter cette étape sur un serveur doté d’une distribution Linux compatible.
    Vous devez bénéficier d’un accès SSH à votre serveur et d’un compte "root" afin de l’utiliser, ce qui permettra d’installer les dépendances. Contactez votre hébergeur si vous ne disposez pas de cela.

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • DirectShow RTSP SourceFilter with MPEG-4 Video Stream

    20 mars 2021, par Novalis

    I create a simple direct show source filter using FFmpeg.I read rtp packets from RTSP source and give them to decoder. It works for h264 stream.

    



    MyRtspSourceFilter[H264 Stream] ---> h264 Decoder --> Video Renderer


    



    The bad news is that it does not work for MPEG-4. I can able to connect my rtsp source filter with MPEG-Decoder. I got no exception but video renderer does not show anything. Actually just show one frame then nothing [just stop]... Decoders and Renderers are 3rd party so i can not debug them.

    



    MyRtspSourceFilter[MP4 Stream] ---> MPEG-4 Decoder --> Video Renderer


    



    I can able to get rtp packets from MPEG-4 RTSP Source using FFmpeg sucessfully.There is no problem with it.

    



    


    It seems that i have not set something(?) in my Rtsps Source
 Filter which is not necessary for H264 stream but may be important for
 MPEG-4 stream

    


    



    What may cause this h264 stream and MPEG-4 stream difference in a direct show rtsp source filter ? Any ideas.

    



    More Info :

    



    — First i try some other rtsp source filters for MPEG-4 Stream...Although my rtsp source is same i see different subtypes in their pin connections.

    



    — Secondly i realy get suspicious if the source is really MPEG-4 SO i check with FFmpeg...FFmpeg gives the source codec id as "CODEC_ID_MPEG4".

    



    Update : 
[ Hack ]

    



    I just set m_bmpInfo.biCompression = DWORD('xvid') it just worked fine...But it is static. How to dynamically get/determine this value using ffmpeg or other ways...

  • Android : How to record the mobile screen without using USB cable ?

    21 juin 2012, par Rajesh

    I want to build an application which would record my screen activities and would store them in a video file.

    1) I need to take the screenshots of my screen movements at periodic intervals and store them on the SD card.

    2) How can I create the video from the images which are already available on my SD card. I have tried with the FFMPEG. But I have encountered a few problems I don't know how to solve. The truth is I don't know the program to convert them.

    3 ) Is it possible to show the picture in my camera ?? That means if a user opens the camera from my app, it should show the pictures which are available on the SD card. If so, please advice me.

    EDIT : I have made a sample which can capable of taking 7 screen shots per second.

    Thanks,
    Rajesh .
