deepstream-test1-app sample is running without showing anything

Hi, I have tried the second suggested option and get the following error after a “deepstream” window is opened for a moment:

(deepstream-app:6839): GLib-GObject-WARNING **: 09:07:09.261: g_object_set_is_valid_property: object class ‘avenc_mpeg4’ has no property named ‘iframeinterval’

(deepstream-app:6839): GLib-GObject-WARNING **: 09:07:09.261: g_object_set_is_valid_property: object class ‘avenc_mpeg4’ has no property named ‘bufapi-version’
libEGL warning: DRI2: failed to authenticate

Runtime commands:
h: Print this help
q: Quit

p: Pause
r: Resume

NOTE: To expand a source in the 2D tiled display and view object details, left-click on the source.
To go back to the tiled display, right-click anywhere on the window.

By the way, If I run with fakesink I get “tQuitting
App run successful”
but don’t see anything
