  • 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 :
