How to enable "sout" for vlc iOS?

[hsc]

Hello :
Anyone know how to enable vlc "sout" for iOS ?
Someone said to modify
1. vlc -》 extras -》 package -》ios -》build.sh
=> to remove "--disable-sout"
2. "Modules.am" in "vlc -》 modules -》access_output"
=> to modify as this :
SOURCES_access_output_dummy = dummy.c
SOURCES_access_output_file = file.c
SOURCES_access_output_udp = udp.c
SOURCES_access_output_http = http.c bonjour.c bonjour.h
SOURCES_access_output_shout = shout.c

access_output_LTLIBRARIES += \
libaccess_output_dummy_plugin.la \
libaccess_output_file_plugin.la \
libaccess_output_udp_plugin.la \
libaccess_output_http_plugin.la

#libaccess_output_udp_plugin_la_SOURCES = udp.c
#libaccess_output_udp_plugin_la_LIBADD = $(SOCKET_LIBS) $(LIBPTHREAD)
#access_output_LTLIBRARIES += libaccess_output_udp_plugin.la

libaccess_output_livehttp_plugin_la_SOURCES = livehttp.c
libaccess_output_livehttp_plugin_la_CFLAGS = $(AM_CFLAGS) $(GCRYPT_CFLAGS)
libaccess_output_livehttp_plugin_la_LIBADD = $(GCRYPT_LIBS) -lgpg-error
if HAVE_GCRYPT
access_output_LTLIBRARIES += libaccess_output_livehttp_plugin.la
endif

but it not work, because the content is very difference.
Anyone knows how to?
Thanks
