• AR Drone 2.0 video streaming whitout SDK on iOS

  10 janvier 2014, par JosephITA

  I'm coding an app for iOS that interact with the AR Drone 2.0 without using the SDK (poor documentation on the iPhone example).
  At the moment I can send command and receive navdata.
  I have no idea in how to receive video streaming. I know that is an H.264 stream and that I can use ffmpeg, but I'm not sure that this solution will pass the Apple revision.
  Any ideas ?

• x264 Encoding use x264_picture_clean crash

  5 mai 2017, par Wong Sam

  When I use iphone encoding CMSampleBufferRef To H264, it offen crash at x264_picture_clean I dont’t know how to deal it

  enter image description here

  x264_picture_t* pPic_in; 

  here is my init about pPic_in

  pPic_in = (x264_picture_t*)malloc(sizeof(x264_picture_t));
  
  pPic_out = (x264_picture_t*)malloc(sizeof(x264_picture_t));
  
  
  
  x264_picture_init(pPic_out);
  
  
  
  x264_picture_init(pPic_in);
  
  x264_picture_alloc(pPic_in, csp, pParam->i_width, pParam->i_height);
  
  
  
  pPic_in->img.i_stride[0] = width;
  
  pPic_in->img.i_stride[1] = width / 2;
  
  pPic_in->img.i_stride[2] = width / 2;
  
  pPic_in->img.i_plane = 3;

  and i set data here

      picture_buf = yuv420_data;
  
      pPic_in->img.plane[0] = picture_buf;
  
      pPic_in->img.plane[1] = picture_buf + y_size;
  
      pPic_in->img.plane[2] = picture_buf + y_size*5/4;

  it looks well , when i run it on my iphone,but sometimes it will crash at

  x264_picture_clean

  here is more detail abuot pPic_in when crash occer
