-Subject: [PATCH 1/4] basetextoverlay: make memory copy when video buffer's
- memory is ready only
-
-1. since gst_buffer_make_writable just lookup the refcount to determine if
-   a buffer is writable, and it will use _gst_buffer_copy() which don't
-   perform a deep memory copy even if the flag of a memory is set to
-   GST_MEMORY_FLAG_READONLY. So, we detect the memory flag and use
-   gst_buffer_copy_region with GST_BUFFER_COPY_DEEP parameter to perform
-   deep memory copy. if the allocator of a memory don't support mem_copy
-   interface, the it will return NULL, if this case, we can use
-   gst_buffer_make_writable() to get a shared memory buffer or the orignal
-   buffer if the buffer's refcount is 1.
-2.  new feature is no added if caps has no feature during caps negotiation
