Gstreamer Pipeline Not working as expected?

[Ish]

Need help with Zed Gstreamer Pipeline with zedsrc (source element ) !! @Honey_Patouceul

Hi,
We would suggest check if the pipeline works in gst-launch-1.0 commands. And then apply to C code. May try to construct the pipelines one-by-one:

gst-launch-1.0 zedsrc ! fakesink

gst-launch-1.0 zedsrc ! clockoverlay ! fakesink

gst-launch-1.0 zedsrc ! clockoverlay ! autovideoconvert ! fakesink

...
