  • MediaSPIP 0.1 Beta version

    25 avril 2011, par

    MediaSPIP 0.1 beta is the first version of MediaSPIP proclaimed as "usable".
    The zip file provided here only contains the sources of MediaSPIP in its standalone version.
    To get a working installation, you must manually install all-software dependencies on the server.
    If you want to use this archive for an installation in "farm mode", you will also need to proceed to other manual (...)

  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Using ffmpeg avcodec_decode_video2 got_picture_ptr returns 0

    3 septembre 2014, par kaiken

    I’m trying to playback the gopro live feed which consists of a series of very short .ts files encoded using H264. I tested it on videos with different containers (mkv,avi,mp4) and different codecs (MPEG4, H264, MSVIDEO1). However, the files from the gopro always returns got_picture_ptr as 0 from avcodec_decode_video2 while the function returns the packet’s size. If I use ffplay or vlc it play the file without problem. I’m not sure what I’m doing wrong. I’m not very experienced with ffmpeg or video in general.

    Here is my test code. I based it off of this tutorial which is out of date but I was able to update the depreciated functions.

    AVFormatContext *pFormatCtx = NULL;
    
AVCodecContext *pCodecCtx;
    
AVStream *pStream = NULL;
    
int videoStream;

   return -1;
    
//av_dump_format(pFormatCtx, 0, path, 0);
    

    
// Find the first video stream
    
for(int i=0; inb_streams; i++)
    
   if(pFormatCtx->streams[i]->codec->codec_type==AVMEDIA_TYPE_VIDEO)
    
   {
    
      pStream=pFormatCtx->streams[i];
    
      videoStream = i;
    
      break;
    
   }

   return -1; // Didn't find a video stream
    

    
// Get a pointer to the codec context for the video stream
    
pCodecCtx=pStream->codec;
    

    
// Find the decoder for the video stream
    
pCodec=avcodec_find_decoder(pCodecCtx->codec_id);

   fprintf(stderr, "Unsupported codec!\n");

}

if(pFrameRGB==NULL)
    
   return -1;
    

    
MakeBitmap(*params->memdc,membmp,(void**)&membits,pCodecCtx->width,pCodecCtx->height);
    
// Assign appropriate parts of buffer to image planes in pFrameRGB
    
// Note that pFrameRGB is an AVFrame, but AVFrame is a superset
    
// of AVPicture
    
avpicture_fill((AVPicture *)pFrameRGB, membits, PIX_FMT_RGB24,
    
               pCodecCtx->width, pCodecCtx->height);
    

    
while (av_read_frame(pFormatCtx, &packet) >= 0)
    
{
    
    // Is this a packet from the video stream?
    
    if (packet.stream_index == videoStream)
    
    {
    
        // Decode video frame
    
        int bytesUsed = avcodec_decode_video2(pCodecCtx, pFrame, &frameFinished, &packet);
    
        // Did we get a video frame?
    
        if(frameFinished)
    
        {
    
           //Do stuff with frame

  • lavd/v4l2 : do not fail when VIDIOC_ENUMSTD returns ENODATA

    18 août 2014, par Andre Wolokita
    lavd/v4l2 : do not fail when VIDIOC_ENUMSTD returns ENODATA

    As of September 14 2012, v4l_enumstd() will return ENODATA
    
when a device’s std field is set to 0. That is, the device
    
does not have a standard format. In order to properly
    
handle this case, v4l2_set_parameters should catch the
    
ENODATA code and break instead of failing.
    

    Below is the v4l2-core commit describing this change.

  • Demultiplex UDP live stream to multiple single live stream outputs using FFMPEG & FFSERVE

    17 février 2017, par tiras muturi

    i have a problem with ffmpeg. i have an input live stream that has 8 inputs and i want to use ffmpeg to convert it from udp live steram to tcp livestream and then extract each of the 8 input stream differently.

    i have been reading about the ffmpeg documentation at they havent provided a clear way of solving my problem.

    am running

    ffmpeg version 3.2.4-1~16.04.york0 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.1 (Ubuntu 5.4.1-5ubuntu2~16.04.york1) 20170210 configuration: --prefix=/usr --extra-version='1~16.04.york0' --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --enable-gpl --disable-stripping --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libebur128 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libopencv --enable-libx264 --enable-shared libavutil 55. 34.101 / 55. 34.101 libavcodec 57. 64.101 / 57. 64.101 libavformat 57. 56.101 / 57. 56.101 libavdevice 57. 1.100 / 57. 1.100 libavfilter 6. 65.100 / 6. 65.100 libavresample 3. 1. 0 / 3. 1. 0 libswscale 4. 2.100 / 4. 2.100 libswresample 2. 3.100 / 2. 3.100 libpostproc 54. 1.100 / 54. 1.100

    am running this command to help me split my input into multiple output that can be accessed differently.
