I have installed Gstreamer on my i.MX6 board. I want to stream the camera connected using RTSP.
The following command displays the camera content on the LVDS screen:
gst-launch tvsrc ! Imxv4vl2sink
Instead of displaying it on the screen, I want to send the content over network RTSP and display it on other device's display
I used the following command to start streaming which works without throwing any error
gst-launch-0.10 -vv imxv4l2src ! video/x-raw-yuv, framerate=30/1, width=1024
, height=768 ! vpuenc codec=avc ! rtph264pay ! udpsink host=127.0.0.1 port=5004
sync=false
On the other device, I executed the following command:
gst-launch rtspsrc location=rtsp://<ip Address>:5004 name=source ! queue ! rtph264depay !
vpudec low-latency=true ! imxv4l2sink
It fails with the following error:
gstrtspsrc.c(5685): gst_rtspsrc_retrieve_sdp (): /GstPipeline:pipeline0/GstRTSPSrc:source:
Failed to connect. (System error: Connection refused)
I can ping from the other device to the streaming device.
What can be the issue?
You are sending RTP over UDP, but do not provide any RTSP protocol. So your receiver which tries to connect via RTSP will fail. You either need to use the GstRTSPServer class and implement some logic as an application on the sender side or receive your data via udpsrc. For the latter you still need a way to transmit SDP data (which usually is one thing an RTSP server does).

I want to stream video from an IP camera TS-WPTCAM.
I can directly stream the video in vlc using rtsp://192.168.100.50:19112/ipcam_h264.sdp but when i try with Gstreamer, it does not play the video.
Below is the output.

The error seems to be the same.
You are depayloading H264 from RTP, but you forgot to parse and decode it before passing it to autovideosink. I also don't know why you need the demux part, because you use only video and only one stream.
Try the following:
gst-launch-1.0 -v rtspsrc location="rtsp://192.168.100.50:19112/ipcam_h264.sdp" ! queue max-size-buffers=2 ! rtph264depay ! h264parse ! decodebin ! autovideosink sync=false
Not sure for your case, but IIRC there may be RTSP authentication problems with some gstreamer versions if plugins-ugly is installed. You may try:
sudo apt-get remove gstreamer1.0-plugins-ugly
If not enough you may share the sdp for further advice.
Using mplayer here:
mplayer rtsp://username:password#IPADDRESS:PORT/your-path-to-stream
I would like to stream with rtsp using GStreamer pipeline elements. First, I checked with gst-inspect-1.0 that rtspclientsink is available:
xilinx-k26-starterkit-2020_2:/# gst-inspect-1.0 | grep rtsp
rtspclientsink: rtspclientsink: RTSP RECORD client
rtsp: rtspsrc: RTSP packet receiver
rtsp: rtpdec: RTP Decoder
Then, wrote simplest pipeline and tested it with videotestsrc as source and kmssink as the sink. Following pipeline works well:
gst-launch-1.0 videotestsrc ! video/x-raw, width=1920, height=1080 ! kmssink bus-id=fd4a0000.zynqmp-display fullscreen-overlay=1 sync=false
Then, changed sink to rtspclientsink:
gst-launch-1.0 videotestsrc ! video/x-raw, width=1920, height=1080 ! rtspclientsink location=rtsp://localhost:554/test
However, even with a simple pipeline, stream could not be started and encountered with the error:
xilinx-k26-starterkit-2020_2:/# gst-launch-1.0 videotestsrc ! video/x-raw, width=1920,height=1080 ! rtspclientsink location=rtsp://localhost:554/test

Could anyone enlighten me about the error and the way I can use rtspclientsink as a sink? I also considered to stream with a script (given below) which uses rtsp server as follows but I wonder is it possible to use rtspclientsink as an pipeline element.Thanks.

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

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

I have tried an example on Ubuntu 19.04
gst-launch-1.0 videotestsrc ! v4l2sink device=/dev/video10
But gstreamer fails

Why it doesn't work? I haven't found this in the documentation, do I need to create /dev/video10 somehow?
I did the same for the default device /dev/video1, but it is an input camera device on my laptop:

Thank in advance.
The title of your questions suggests you would like to write to a virtual video device. v4l2 devices can be both input and output video devices. Your camera is a video input (capture) device. Directing a v4l2sink (so an endpoint of the pipeline) in gstreamer will likely fail.
You can however generate a virtual output device. What you are looking for is something like the v4l2-loopback device. It allows you to generate a virtual /dev/video10 device like this:
modprobe v4l2loopback video_nr=10
Another possible solution for the same error message: recreate the v4l2loopback interface:
sudo rmmod -f v4l2loopback
sudo modprobe v4l2loopback
This might apply to others experiencing the error message from the original question, but who are already aware they need a v4l2loopback device as gstreamer sink.
When trying to stream a video to the existing v4l2loopback device I streamed to using ffmpeg before, I got the same error message
Device '/dev/video0' is not a output device.
Investigation
When comparing the state of a working loopback video device and a non-working one (i.e. after writing to it with ffmpeg) with v4l2-ctl --all -d 0 using diff, I found the following difference :
--- working 2020-11-19 18:03:52.499440518 +0100

Somehow that "Video Output" capability is required for gstreamer to work successfully and taken away by my previous ffmpeg call.
The behaviour only occured when I loaded the v4l2loopback module with the exclusive_caps=1 option, see 1.
The solution was to unload / load the v4l2loopback kernel commands, forcefully removing the v4l2loopback kernel module and adding it again using rmmod / modprobe (see above).
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.
