/**
 * gst_parse_launchv_full:
 * @argv: (in) (array zero-terminated=1): null-terminated array of arguments
 * @context: (allow-none): a parse context allocated with
 *     [gst_parse_context_new](), or [NULL]()
 * @flags: parsing options, or [GST_PARSE_FLAG_NONE]()
 * @error: pointer to a [GError]() (which must be initialised to [NULL]())
 *
 * Create a new element based on command line syntax.
 * _error_ will contain an error message if an erroneous pipeline is specified.
 * An error does not mean that the pipeline could not be constructed.
 *
 * Returns: (transfer floating): a new element on success; on failure, either [NULL]()
 *   or a partially-constructed bin or element will be returned and _error_ will
 *   be set (unless you passed [GST_PARSE_FLAG_FATAL_ERRORS]() in _flags_, then
 *   [NULL]() will always be returned on failure)
