@brief Create a frame object based on an externally created buffer.

@attention The buffer is owned by the user and will not be destroyed by the frame object. The user should ensure that the buffer is valid and not modified. @attention The frame object is created with a reference count of 1, and the reference count should be decreased by calling @ref ob_delete_frame() when it is no longer needed.

@param[in] frame_type Frame object type. @param[in] format Frame object format. @param[in] buffer Frame object buffer. @param[in] buffer_size Frame object buffer size. @param[in] buffer_destroy_cb Destroy callback, will be called when the frame object is destroyed. @param[in] buffer_destroy_context Destroy context, user-defined context to be passed to the destroy callback. @param[out] error Pointer to an error object that will be set if an error occurs. @return ob_frame* Return the frame object.
