<div dir="ltr">Hi, I am writing an application using Gstreamer SDK. I am facing following two issues. I have missed something or these are issues in Gstreamer SDK ? no element "vp8enc": Included following plugins and used vp8enc in pipeline. GSTREAMER_PLUGINS := $(GSTREAMER_PLUGINS_CORE) $(GSTREAMER_PLUGINS_PLAYBACK) $(GSTREAMER_PLUGINS_CODECS) $(GSTREAMER_PLUGINS_CODECS_RESTRICTED) $(GSTREAMER_PLUGINS_NET) $(GSTREAMER_PLUGINS_SYS) It seems that Gstreamer is unable to find vp8enc, although vp8 plugin entry is in gstreamer_android.c.
