-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
