/** @page scan_media Scanning URL for embedded media URLs

libquvi may be used to scan an URL for embedded media URLs. Many
websites use embedded URLs to media, one such example are the blogs that
embed YouTube videos.

@code
quvi_scan_t qs = quvi_scan_new(q, URL);
abort_if_error();
{
  char *s = NULL;
  while ((s = quvi_scan_next_media_url(qs)) != NULL)
    puts(s);
}
quvi_scan_free(qs);
qs = NULL;
@endcode

The available @ref scan_script collection determines which
embedded URLs may be found by the scan from the URL.
