  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Ffmpeg 2 Input cameras in single ouput

    1er juin 2020, par Expressingx

    I have app where it streams from a camera to a file with Preview using liabv. 
Now there is requirement to be able to stream from 2 cameras simultaneously and output to a single file. The Preview will be like a CCTV camera and written to single output. Is this possible with libav ?
Before doing anything I've tried with ffmpeg.exe directly and found this :

    



    ffmpeg -f dshow -i video="Camera1" -i video="Camera2" -filter_complex "nullsrc=size=640x480 [base];[0:v] setpts=PTS-STARTPTS, scale=640x480 [upperleft];[1:v] setpts=PTS-STARTPTS, scale=640x480 [upperright];[base][upperleft] overlay=shortest=1 [tmp1];[tmp1][upperright] overlay=shortest=1:x=640:y=480 [tmp2];"-c:v libx264 output.mp4


    



    But every time throws error 'No such file or directory' for the second camera, while I've verified the camera is working if I use it as single input. Do I miss something ?

    



    Overall is it possible to achieve that ?

  • FFMPEG avcodec_find_decoder(2) (CODEC_ID_MPEG2VIDEO) always returns incomplete AVCodec ?

    22 octobre 2012, par Passer

    I got a problem with FFMPEG (avcodec-54.dll)
    1) I wrote a .NET wrapper. As far as I can see it works well.
    2) I try to decode something... and thats were the problem is :

    ...
    
  FFmpeg.avcodec_register_all();
    

    
  pAVCodec = FFmpeg.avcodec_find_decoder(CodecID.CODEC_ID_MPEG2VIDEO); //which is in int 2
    
  Console.WriteLine("CodecID " + (*pAVCodec).id);
    
  Console.WriteLine("CodecType " + (*pAVCodec).type);
    
  Console.WriteLine("CodecName " + (*pAVCodec).name);
    
....

    No EXC was thrown and the following output came :

    CodecID CODEC_ID_NONE
    
CodecType 1790854254
    
CodecName mpeg2video

    What confuses me the most is that the name is correct, but the id and type are wrong.
    In the previous Version if the DLL everything works fine. This behaviour came up with the new version.
    Any guesses or debugging tips ?
