• 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
