  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • RTSP Client for H264 Audio/Video Stream

    9 février, par Jean-Philippe Encausse

    I'm looking for a simple way to get data of an IP Camera RTSP Stream (using H264 Audio/Video) and get on the other side

    



      

    • a frame by frame byte[]
    • 


    • a stream of the audio
    • 


    



    After many research

    



      

    • EmguCV Capture seems hanging forever (no answer from forum)
    • 


    • There is many (too big) RTSP Server few decode H264
    • 


    • There is "slow" ffmpeg wrapper
    • 


    • There is some managed DirectShow wrapper
    • 


    



    So I don't know where to go ? And how to do this ?

    



    It seems iSpyCamera is doing the job but it's a big project not a little library to query ip cameras.

    


  • Script for muxing audio and video files with same name using FFmpeg

    26 juillet 2024, par Madamadam

    I have a folder that contains audio and video files named like file001.wav and file001.mp4 and i want them to be muxed automatically. I've found a script for windows, but do not know how to alter it for OS X/Linux. Could someone help ?
Here's the windows script :

    



    for %%a in ("*.mp4") do ffmpeg -i "%%~na.wav" -i "%%~na.mp4" -acodec copy -vcodec copy "newfiles\%%~na.mp4"


    


  • Recording video in C#

    31 juillet 2014, par pfedotovsky

    I have to do the following : record video from camera using C#. Camera I use produces video frames (framerate is not fixed) and I have to somehow put all the frames together and create video file. Also I need to use different codecs such as AVI or MPEG4 (these codecs are required, others are optional).

    The main problem I faced is how to create video in which framerate is not fixed. I have a stream of frames, for example I can recive the first frame after 1ms, then after 20ms, then 36ms and so on. If I create video with 25 frames/second the result will be wrong because it means that frames are added after 40ms.

    I tried to use Aforge.Video library, it has a method http://www.aforgenet.com/framework/docs/html/84a560df-bfd5-e0d6-2812-f810b56a254d.htm which adds a frame according to timespan. But this method has problems with setting bitrate - the bitrate value I pass to the method simply ignored (http://www.aforgenet.com/forum/viewtopic.php?f=2&t=2665).

    So my questions is : is there some C# library which I can use to video recording ? I have to support AVI and MPEG4, also possibility to set bitrate and the last but not the least - record video with variable framerate.

    Thanks in advance. Any suggestions would be very helpful.

    UPD1 : I can’t connect to camera directly - all I have is a stream of frames and I need to convert this stream to video at run-time.

    UPD2 : A library I’m looking for should satisfy the following properties. It has to contain a method (or some way how to do the same) to add next frame with a timestamp just like in Aforge.Video.FFMPEG :

    public void WriteVideoFrame(Bitmap frame, TimeSpan timestamp)

    And it should be possible to choose different codecs (at least AVI and MPEG4) and also to set bitrate.
    Is there some alternatives to Aforge.Video.FFMPEG ? Because Aforge doesn’t work properly - the bitrate value is ignored, also some codecs are not supported (MPEG2 for example).

    UPD3 : One more questions about codec license. If I use open source library, should I worry about the codec license ?
