GL: external-oes shader places precision qualifier before #extension (was: androidmedia amcviddec fail after 1.15.90 1.16.0 update)

After updating to 1.15.90 or 1.16.0 Video streaming decoding no longer works on Android. I use libgstreamer_android my config is: GSTREAMER_NDK_BUILD_PATH := $(GSTREAMER_ROOT)/share/gst-android/ndk-build

include $(GSTREAMER_NDK_BUILD_PATH)/plugins.mk GSTREAMER_PLUGINS := coreelements udp rtsp rtpmanager rtp webrtc videoparsersbad openh264 videoconvert opengl androidmedia

GSTREAMER_EXTRA_LIBS := -liconv

G_IO_MODULES := gnutls

GSTREAMER_EXTRA_DEPS := gstreamer-video-1.0

include $(GSTREAMER_NDK_BUILD_PATH)/gstreamer-1.0.mk

and stream config is :

rtspsrc location=%1$s " + "tls-validation-flags=generic-error " + "latency=1000 ! "
                + "rtph264depay ! " + "h264parse ! " + "amcviddec-(hw decoder found on Android with MediaCodecList) !" + "videoconvert ! "
                + "glimagesink queue2

with 1.15.2 Gstreamer stream playback is working fine, however after update to 1.15.90 or 1.16.0 stream is failing with such error:

can somebody please help? is this a GStreamer lib error or I'm missing some config?
