How to add glib-networking GIO/GnuTLS modules while building for Android?

[saepia]

Hello,

I am building an app for Android, and when I create custom TLS Database, I get the error that " TLS support is not available".

That typically happens when GIO/GnuTLS modules are not available.

I am aware I can add it using standard methods for using prebuilt libraries, but is there any preferred way to add them to the gstreamer_android.so bundle?

My current GSTREAMER_EXTRA_DEPS are glib-2.0 gio-2.0

I am using 1.8.0.

Thanks,

Marcin

Use
  G_IO_MODULES := gnutls
in Android.mk

That's then also adding GST_G_IO_MODULE_DECLARE(gnutls)
and GST_G_IO_MODULE_LOAD(gnutls) to gstreamer_android.c.

Thank you!

I've found out that additionally I have to call gst_android_load_gio_modules() in my JNI code.

gst_android_init() from gstreamer_android.c should do that for you
already. It doesn't?

The error are as seen in the attachments. Error message is 'TLS support is
not available'. So obviously I am somehow not linking against gnutls in
xcode.

Ok for Gstreamer 1.1.6 I found out that the following paragraph in release
notes

The way that GIO modules are named has changed due to upstream GLib natively
adding support for loading static GIO modules. This means that any GStreamer
application using gnutls for SSL/TLS on the Android or iOS platforms (or any
other setup using static libraries) will fail to link looking for the
g_io_module_gnutls_load_static() function. The new function name is now
g_io_gnutls_load(gpointer data). data can be NULL for a static library. Look
at [this commit][gio-gnutls-static-link-example] for the necessary change in
the examples.


So I made the following change in the code in gst_ios_init.h but I think I
am not using API correctly

//For g_io_module_gnutls_load_static

//#define GST_G_IO_MODULE_DECLARE(name) \
//extern void G_PASTE(g_io_module_, G_PASTE(name, _load_static)) (void)

//#define GST_G_IO_MODULE_LOAD(name) \
//G_PASTE(g_io_module_, G_PASTE(name, _load_static)) ()

//For g_io_gnutls_load

#define GST_G_IO_MODULE_DECLARE(name) \
extern void G_PASTE(g_io_, G_PASTE(name, _load)) (void)

#define GST_G_IO_MODULE_LOAD(name) \
G_PASTE(g_io_, G_PASTE(name, _load)) ()

You are getting a link error vs x86_64, are you trying to compile towards that target od to ARM?

the problem disappears when I use Gstreamer binaries 1.14 instead of 1.16 for
iphone 8 plus...strange?

Seems related to this change:

https://gitlab.freedesktop.org/gstreamer/gst-examples/commit/ef7abd54a85990b95438b0d075d6e625dc5fade0

We have moved from our own hack to support static glib-networking
modules to what was decided upstream. This will be added to the release
notes.

p.s. It's better to say that you are using 1.15.1 binary, which clearly
indicates that this is pre-release material, otherwise it's confusing
for mailing list readers, and even for people supporting.

ok will do. BTW where can I find the example gio-gnutls-static-link-example?
