Unable to build pipeline error.

[AHMET FURKAN AKSOY]

I am trying to run GStreamer android example 5. It compiles and runs but instead of transferring video I am getting an error on the screen.

Unable to build pipeline: no element "avdec_h264"

How can I solve this.

You need to add the libav plugin to your build, by adding it to the
GSTREAMER_PLUGINS variable in jni/Android.mk

Either by adding libav specifically, or
$(GSTREAMER_PLUGINS_CODECS_RESTRICTED) which also comes with other
plugins.

I added GSTREAMER_PLUGINS_CODECS_RESTRICTED and now ı get a new error:

I get this error when ı use default pipeline(playbin) and also a buffering error on the phone. When I use my custom pipeline I get:
