[Buildroot] How do I enable webrtc as part of external gstreamer, in buildroot

[Vered Kalef]

Hi all,
I'm trying to install external gstreamer with webrtc enabled on buildroot.
It seems this option is missing within the buildroot.
I've configured the mk file and the Config.in file.
After installation when I check gst-inspect webrtcbin, I get -

No such element or plugin ?webrtcbin'
What am I missing?
gst1-plugins-bad/Config.in config
BR2_PACKAGE_GST1_PLUGINS_BAD_PLUGIN_WEBRTC bool "webrtc" depends on
!BR2_STATIC_LIBS # libnice -> gnutls select BR2_PACKAGE_GST1_PLUGINS_BASE #
libgstsdp select BR2_PACKAGE_LIBNICE help WebRTC plugins (webrtcbin - a bin
for webrtc connections comment "webrtc needs a toolchain w/ dynamic
library" depends on BR2_STATIC_LIBS gst1-plugins-bad/gst1-plugins-bad.mk
ifeq ($(BR2_PACKAGE_GST1_PLUGINS_BAD_PLUGIN_WEBRTC),y)
GST1_PLUGINS_BAD_CONF_OPTS += --enable-webrtc GST1_PLUGINS_BAD_DEPENDENCIES
+= libnice GST1_PLUGINS_BAD_DEPENDENCIES += gst1-plugins-base libnice else
GST1_PLUGINS_BAD_CONF_OPTS += --disable-webrtc endif

What do your mean with 'external'? Why 'external'?

Which option? There is definitely an GStreamer webrtc option (since
2019.05), see [1]...

Which Buildroot version do you use?

Take a look at the gst1-plugins-bad configure output (or
build/gst1-plugins-bad-<version>/config.log for a hint
what is missing (look for webrtc entries)....

Mind to share your config and/or defconfig file?

Hello Vered,

please keep buildroot at busybox.net in CC

14.0 does not make sense, the buildroot versions are <year>.<month>.<release>,
did you mean 2014.02, 2014.05, 2014.8 or 2014.11?

Please take a look at the build/gst1-plugins-bad-<version>/config.log, is webrtc enabled
e.g.:

configure:91279: *** checking feature: WebRTC ***
configure:91283: *** for plug-ins: webrtc ***
configure:91327: checking for NICE
configure:91335: $PKG_CONFIG --exists --print-errors "nice >= 0.1.14"
configure:91338: $? = 0
configure:91353: $PKG_CONFIG --exists --print-errors "nice >= 0.1.14"
configure:91356: $? = 0
configure:91396: result: yes
configure:91412: *** These plugins will be built: webrtc

Nothing new, gstreamer is unable to find an element named webrtcbin,
make sure the plugin libgstwebrtc.so is build and installed (at the right
location and with the right dependencies) at the target...

This file made the difference. It seems the problem is an old version of
libnice, it should be greater than 0.1.14, so, I think I'll upgrade to
buildroot 2018.11, which holds libnice 0.1.14
and create the external gstreamer with webrtc enabled as you've done in
version 2019.5.
In your opinion will it do the work?

Maybe, you have to try it on your own ;-)

Alternative is to cherry-pick/back-port some patches to your buildroot
version, e.g. (untested):

	$ git clone git://git.busybox.net/buildroot
	$ cd buildroot
	$ git checkout 2018.02.9
	$ git checkout -b 2018.02.9-patched

	# libnice: bump to version 0.1.14
	$ git cherry-pick 16012f56cade49e7ca5d33ecdd6226c1b19fc4ac

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

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

 If you can anyway upgrade buildroot as a whole (which is the safer option),
then it's better to upgrade to either 2019.05 (which already contains gst-webrtc
support) or to 2019.02 (because that's an LTS release).

[Buildroot] How do I enable webrtc as part of external gstreamer, in buildroot

[Vered Kalef]

Hi All
Thank you very much for your help!!
I managed to install webrtc with libnice 0.1.14, both as gstreamer external
components on buildroot!!
I still don't see video because I fail with exception
on g_signal_emit_by_name(webrtc, "get-transceivers", &transceivers).
But I think it is better to open a new mailing list on that, right?
although I remember I read something about it, so I'll first google it.
Much appreciated!
Vered
