<p>Hi Akmal,</p>
<p>That pipeline indicates that there is no link between filesink
and nvcamerasrc. So, filesink is the end of a line and
nvcamerasrc is the start of a new line.</p>
<p>The same thing happens after h264parse ! mux.video_0</p>

I'm on Jetson TX2, I tried the pipeline with '<b>nvcamerasrc</b>'
as the video source element and it works! I also
modified the pipeline for video recording and for
sending stream over network by TCP only without the
preview queue. So, it goes like this :</p>

to this guide, I managed to launch this on command line.
I'm used to transform gstreamer pipeline into C/C++
programming code but I'm still a beginner. However, this
is my first time I saw this form of pipeline where it
starts with the muxer and then the "<b>filesink</b>" and
"<b>nvcamerasrc</b>" elements are bordered in the same
"! ...!" like this "<b>! filesink
location=/media/nvidia/SSDJetson/test.mp4 nvcamerasrc
fpsRange="30.0 30.0" !</b>". I'm not familiar at all
with this form of pipeline but I wanted to transform
this into code.</p>

have two problems, I don't know how to create the "<b>filesink</b>"

Plus, I don't know how to transform "<b>mux.video_0
