[Buildroot] Installed external gstreamer, enabled WebRTC and installed external libnice plugins to buildroot, however, libnice is missing

[Vered Kalef]

Hi all,
I'm working with buildroot 18.02.
I've installed External gstreamer version 14.0.
I've managed to update the plugins-bad, to hold webrtc option.
For the webrtc I had to update libnice version, so I've installed it as
external libnice 0.1.14.
Now -
gst-inspect-1.0 webrtc
shows that webrtc exists!

Should it work as well:
gst-inspect-1.0 libnice

Is the installation of libnice as external is problematic?
I've called the external plugin CUSTOM_LIBNICE and referred to it from
custom-gst1-plugins-bad.mk -

ifeq ($(BR2_PACKAGE_CUSTOM_GST1_PLUGINS_BAD_PLUGIN_WEBRTC),y)
CUSTOM_GST1_PLUGINS_BAD_CONF_OPTS += --enable-webrtc
CUSTOM_GST1_PLUGINS_BAD_DEPENDENCIES += custom-gst1-plugins-base
CUSTOM_LIBNICE
else
CUSTOM_GST1_PLUGINS_BAD_CONF_OPTS += --disable-webrtc
endif

 I don't think libnice itself is a gstreamer plugin, so this wouldn't work. I
might be wrong though.

 I guess it is custom-libnice here, not CUSTOM_LIBNICE?

 Can you check what the build log says about libnice?

 Can you check if libnice is installed on your target?

 Arnout

[Buildroot] Installed external gstreamer, enabled WebRTC and installed external libnice plugins to buildroot, however, libnice is missing

[Vered Kalef]

Hi
upgraded buildroot version to 2018.05.3, so, I'll have libnice 1.14 built
in .
I enabled it.
Restored the connection between webrtc and original libnice.
I saw that I should have the plugins nicesrc and nicesink (the plugins are
part of libnice associated with gstreamer).
Still I get that libnice is missing in the installation - libnice elements
are not available
I'm still missing an installation.
Regards,
Vered

As already said in [1] you need the following patches (not included in 2018.5,
but on master or 2019.05):

	# libnice: add gstreamer support [2]
	$ git cherry-pick 689c083f571e0c88463a451cb4e64c1470b67afb

	# package/gst1-plugins-bad: add webrtc option [3]
	$ git cherry-pick baffecda1678d68ab6d16514ae1903d2d4dc1e5d
