    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • How to play multiple video on top of each other with ffmpeg c programming

    13 septembre 2016, par Tom Goldberg

    I’m trying to develop a code which can plays multiple videos simultaneously with ffmpeg.
    I need to play a video on a 2x2 matrix background and another video in the top left corner of it.
    Problem : The top left corner video is flicking and not stable enough.
    top-left video is flicking while playing
    code :

    SDL_Surface *screen = SDL_SetVideoMode(640, 480, 24, 0);
    
void video_display(VideoState *is) {
    
  SDL_Rect rect;
    
  VideoPicture *vp;
    
  int w, h, x, y;
    
  h = screen->h;
    
  w = ((int)rint(h * aspect_ratio)) ;
    
  if(w > screen->w) {
    
    w = screen->w;
    
    h = ((int)rint(w / aspect_ratio)) ;
    
  }
    

    
  rect.x = (screen->w - w) / 2;
    
  rect.y = (screen->h - h) / 2;
    

    
  if(  is->video_id == 0 ){
    
     rect.w = w;
    
     rect.h = h;
    
     SDL_DisplayYUVOverlay(vp->bmp, &rect); // i think the problem is over here
    
  }
    
  else if( is->video_id == 1 ){
    
     rect.w = w/2;
    
     rect.h = h/2;
    
     SDL_DisplayYUVOverlay(vp->bmp, &rect);
    
  }  

    When i choose 0/1, i move between audio only.
    My question is : What should i code in order to make the top-left video stable to view ?

  • How to play a part of the MP4 video stream ?

    14 novembre 2014, par AgentFire

    I have a URL (<ip>/ipcam/mpeg4.cgi</ip>) which points to my IP camera which is connected via Ethernet.
    Accessing the URL resuls in a infinite stream of video (possibly with audio) data.

    I would like to store this data into a video file and play it later with a video player (HTML5’s video tag is preferred as the player).

    However, a straightforward approach, which is simple saving the stream data into .mp4 file, didn’t work.

    I have looked into the file and here is what I saw (click to enlarge) :

    It turned out, there are some HTML headers, which I further on manually excluded using the binary editing tool, and yet no player could play the rest of the file.

    The HTML headers are :

    --myboundary
    
Content-Type: image/mpeg4
    
Content-Length: 76241
    
X-Status: 0
    
X-Tag: 1693923
    
X-Flags: 0
    
X-Alarm: 0
    
X-Frametype: I
    
X-Framerate: 30
    
X-Resolution: 1920*1080
    
X-Audio: 1
    
X-Time: 2000-02-03 02:46:31
    
alarm: 0000

    My question is pretty clear now, and I would like any help or suggestion. I suspect, I have to manually create some MP4 headers myself based on those values above, however, I fail to understand format descriptions such as these.

    I have the following video stream settings on my IP camera (click to enlarge) :

    I could also use the ffmpeg tool, but no matter how I try and mix the arguments to the program, it keeps telling me this error :
