I have installed gstreamer-1.0 on my target board.
When I run the below command:
gst-launch-1.0 filesrc location="/home/test.mp4" ! decodebin ! videoconvert ! xvimagesink
I am getting the following output:
Setting pipeline to PAUSED ...
ERROR: Pipeline doesn't want to pause.
ERROR: from element /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0: Could not initialise Xv output
Additional debug info:
xvimagesink.c(1765): gst_xvimagesink_open (): /GstPipeline:pipeline0/GstXvImageSink:xvimagesink0:
Could not open display (null)
Setting pipeline to NULL ...

Please suggest some solution to make the pipeline work.

Hm do you have libxv somewhere?
Find
what happens when you check gst-inspect-1.0 xvimagesink ?
Also there is library path mentioned (| grep Filename).. you can ldd it:
ldd /usr/local/lib/gstreamer-1.0/libgstxvimagesink.so
I had some problems with this as well.. try to install libxv-dev or libxv1.. maybe dev is safer.

My system main OS is Windows-10 OS and installed WSL2 in subsystem.
Openvino is installed in Linux under WSL2. The reason is dlstreamer-gst is supported only in linux.
When I test the following test app, it works only for fps and display is not working.
If I run app as
./vehicle_pedestrian_tracking.sh person-bicycle-car-detection.mp4 10 CPU fps
I can see the output as
FpsCounter(1sec): total=346.54 fps, number-streams=1, per-stream=346.54 fps
FPSCounter(average): total=340.06 fps, number-streams=1, per-stream=340.06 fps

When I run for display,
./vehicle_pedestrian_tracking.sh person-bicycle-car-detection.mp4 10 CPU dispaly
I have error as

Is it display is not available in WSL subsystem?
Use MobaXTerm with WSL2 and change the command of xvimagesink to ximagesink in vehicle_pedestrian_tracking.sh.
My solution is I can't display but I can save to file as
gst-launch-1.0 filesrc location=video1.avi ! decodebin ! video/x-raw ! queue ! gvadetect model=/home/nyan/intel/dl_streamer/models/intel/vehicle-detection/FP16/model_fp16.xml model-proc=./model_proc/vehicle-detection.json inference-interval=10 threshold=0.6 device=CPU ! queue ! gvafpscounter ! filesink location=output.avi
I'm following a guide in https://tsn.readthedocs.io/avb.html#gstreamer-plugin to create a TSN talker, I've followed the guide BUT croscompiling inside a raspberry pi CM4, this has an ARM64 BCM2711.
Once I have all prepared and execute the last step:
sudo gst-launch-1.0 clockselect. \( clock-id=realtime filesrc location=sintel_trailer_720p_TOVERLAY.mp4 ! qtdemux ! h264parse config-interval=-1 ! avtpcvfpay processing-deadline=20000000 mtt=2000000 tu=125000 streamid=0xAABBCCDDEEFF000A ! avtpsink ifname=eth1.5 priority=3 processing-deadline=20000000 \)
I get the following error:

How can I include or replace the qtdemux plugin?
Where is supposed included this in the gstreamer repositories?
Thank in advance for your help.
I am not sure why this pipeline is breaking, I have gstreamer installed on linux from the websites exact instructions, any ideas?

If I change it to:
gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert! videoscale ! video/x-raw, width=2592, height=600 ! autovideosink -v
it will work but why will it not work the other way?
Your webcam transmits raw video output to whoever is listening to it. Adding videoconvert encodes the raw video to a codec that can be manipulated by the videoscale element and the end product of the manipulation to be understood by the autovideosink element.
So gst-launch-1.0 v4l2src device=/dev/video0 ! videoconvert! videoscale ! video/x-raw, width=2592, height=600 ! autovideosink is telling gstreamer to get the raw video from the camera, encode it into something that we understand, alter the video, and display it.
I really recommend that when you have doubts about an element, call gst-inspect-1.0 <element name> to see it's description and properties.
I installed a fresh version of Ubuntu 18.04 and I am trying to demux a single channel from a Matroska file by running the exact command from the Gstreamer documentation ( https://gstreamer.freedesktop.org/documentation/tutorials/basic/gstreamer-tools.html ).
Gstreamer is current:
gst-launch-1.0 --version
gst-launch-1.0 version 1.14.1
GStreamer 1.14.1
https://launchpad.net/distros/ubuntu/+source/gstreamer1.0
The problem is that Gstreamer keeps complaining that:
GstMatroskaDemux:d: Delayed linking failed

How can I get this to work?
I actually remembered that webm is doing matroska file format. The example is actually faulty/out of date. The pad naming is wrong. Instead of 00 use 0:
gst-launch-1.0 souphttpsrc location=https://www.freedesktop.org/software/gstreamer-sdk/data/media/sintel_trailer-480p.webm ! matroskademux name=d d.video_0 ! matroskamux ! filesink location=sintel_video.mkv
I'm trying to use Gstreamer to create a seekable (indexed) video file in Linux. My pipelines work for recording and saving the data, but I can't figure out how to index the data so I can seek using gst_element_seek_simple() [http://docs.gstreamer.com/display/GstSDK/Basic+tutorial+4%3A+Time+management]
I have seen this post: Gstreamer video output position tracking and seeking and validated I am sending an EOS on the pipeline with -e.
Here is my pipeline and output. I'm teeing it to display both to my embedded system's screen and save to the M4V file.

You need to store the result in a seekable/indexed format. For that you can put the mpeg4 video inside a container such as mp4 or matroska. Use "! mp4mux ! filesink" or "! matroskamux ! filesink" to have it inside those formats that should make it seekable.
Side notes: gstreamer 0.10 is over 2 years obsolete and unmantained, please upgrade to 1.0.
