  • Send SDL frame to another process and display it

    18 septembre 2016, par Amit_sh

    I am trying to send a frame to another process in order to display it. I’m using dranger tutorial02.

    I was thinking to serialize the SDL_Overlay struct to bytes after the call to sws_scale, send it to the other process, deserialize it and call SDL_DisplayYUVOverlay to display it.

    Do you think this is my best choice ?

    If so, I’m having hard time serializing this struct.. here’s the code :

    size_t size_of_Overlay(SDL_Overlay *bmp) {
    
    /*
    
     * typedef struct  {
    
     *
    
     *  Uint32 format;
    
     *  int w, h;
    
     *  int planes;
    
     *  Uint16 *pitches;
    
     *  Uint8  **pixels;
    
     *  Uint32 hw_overlay:1; <- can I ignore it? cant point to a bit-field..
    
     *  
    
     *  } SDL_Overlay;
    
     */ 
    
     //      w,h,planes      format             pitches                pixels
    
    return sizeof(int)*3 + sizeof(Uint32) + sizeof(Uint16)*bmp->w + sizeof(Uint8)*bmp->h*3;
    
}
    

    
void overlay_to_buf(SDL_Overlay* bmp, char* buf) {
    

    
    if(!bmp || !buf) {
    
        perror("overlay_to_buf");
    
        exit(1);
    
    }
    

    
    memcpy(buf, &bmp->format, sizeof(Uint32));
    
    buf += sizeof(Uint32);
    

    
    memcpy(buf, &bmp->w, sizeof(int));
    
    buf += sizeof(int);
    

    
    memcpy(buf, &bmp->h, sizeof(int));
    
    buf += sizeof(int);
    

    
    memcpy(buf, &bmp->planes, sizeof(int));
    
    buf += sizeof(int);
    

    
    memcpy(buf, bmp->pitches, sizeof(Uint16)*bmp->w);
    
    buf += sizeof(Uint16)*bmp->w;
    

    
    memcpy(buf, bmp->pixels[0], sizeof(Uint8)*bmp->h);  
    
    buf += sizeof(Uint8)*bmp->h;
    

    
    memcpy(buf, bmp->pixels[1], sizeof(Uint8)*bmp->h);  
    
    buf += sizeof(Uint8)*bmp->h;
    

    
    memcpy(buf, bmp->pixels[2], sizeof(Uint8)*bmp->h);  
    
    buf += sizeof(Uint8)*bmp->h;
    
}
    

    

    
void buf_to_overlay(SDL_Overlay *bmp, char* buf) {
    

    
    if(!bmp || !buf) {
    
        perror("buf_to_overlay");
    
        exit(1);
    
    }
    

    
    memcpy(&bmp->format, buf, sizeof(Uint32));
    
    buf += sizeof(Uint32);
    

    
    memcpy(&bmp->w, buf, sizeof(int));
    
    buf += sizeof(int);
    

    
    memcpy(&bmp->h, buf, sizeof(int));
    
    buf += sizeof(int);
    

    
    memcpy(&bmp->planes, buf, sizeof(int));
    
    buf += sizeof(int);
    

    
    bmp->pitches = (Uint16*)malloc(sizeof(Uint16)*bmp->w);

  • avformat/mov : don't abort on duplicate Mastering Display Metadata boxes

    avformat/mov : don't abort on duplicate Mastering Display Metadata boxes

    The VP9 spec defines a SmDm box for this information, and the ISOBMFF spec defines a
    
mdvc one. If both are present, just ignore one of them.
    
This is in line with clli and CoLL boxes.
    

    Fixes ticket #10711.
