Hello everyone,

The code is like this:

 gst_mini_object_set_qdata( GST_MINI_OBJECT(buffer), 
g_quark_from_static_string("avl_video_display_frame"),  ptr, 0);

   buffer = gst_buffer_make_writable(buffer);

   And then the user_data I set to the buffer is lost.

================================

#define         gst_buffer_is_writable(buf)     gst_mini_object_is_writable
(GST_MINI_OBJECT_CAST (buf))


gst_mini_object_copy-->_gst_buffer_copy-->gst_buffer_copy_into

Should gst_buffer_copy_into copy qdata of gstminiobject ?

Is this a bug?
