Questions[rtsp](ubuntu)

I can ping 192.168.15.20 just fine and the camera's online and I can connect to it with the android app I've tried opening rtsp://admin:[email protected]:554/live/ch00_1 and this is the result from my vlc log file:

I am required to run some video processing algorithms on IP camera stream. I don't have an IP Camera so my idea is to use a webcam as an IP cam for RTSP streaming, which the client machines can acquire and run the algorithms on. I learned that VLC can perform streaming from a webcam. I attached an old webcam to an Ubuntu machine. Here is the information.

$ v4l2-ctl --list-devices
SAMSUNG (SPC-A30M): SAMSUNG (SP (usb-0000:00:14.0-7):
    /dev/video0
    /dev/video1

$ v4l2-ctl --list-formats
ioctl: VIDIOC_ENUM_FMT
    Index       : 0
    Type        : Video Capture
    Pixel Format: 'YUYV'
    Name        : YUYV 4:2:2

Here is the driver info.

When i open MediaStream, do all the steps correctly, I get this error:

Your input can't be opened:
VLC is unable to open the MRL 'v4l2:///dev/video0'. Check the log for detail.

The log file contains:

-- logger module started --
main: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.
main: playlist is empty
v4l2 error: cannot open device '/dev/video0': Operation not permitted
v4l2 error: cannot open device '/dev/video0': Operation not permitted
v4l2 error: cannot open device '/dev/video0': Operation not permitted
v4l2 error: cannot open device '/dev/video0': Operation not permitted

When i open Cheese, the camera is working fine and i can see the video.

For testing purpose, i set the /dev/video0 permissions to 777, still i get the same error.

This Post suggested to add the user to video group, i did that using sudo usermod -aG video ${USER} but no joy.

I also tried Motion in this post, but i couldn't get it working.

I also tried FFmpeg in this post, but i couldn't get that working as well.

I studied and tried this post, this post, this post, and many others, but nothing seems to help.

In the Driver Info section (above), i see not using libv4l2, could it be the cause of the problem? If so, how to solve this issue?

What am i doing wrong? My objective to to provide an RTSP stream form the USB Webcam attached to the Ubuntu Machine, to the client machines for processing in Java or Python. I am not bound to VLC, so i can use anything that gets the job done.

Can anyone suggest a working solution to the VLC problem or suggest any other tool that can do the job?

I tried many posts/solutions but none helped.

I have a camera which gives output in form of RTSP. However we want to run it on a browser inside HTML tag. For which we need HTTP url using terminal. I saw few posts which uses cvlc but I was not able to get the correct output. Is there any way I can achieve it?

Even though both of the applications are built using same opencv backend, why does the vlc player take lesser load (almost half the load) than a python opencv application to stream the same rtsp video from server

I am trying to make a rtsp server that can catch a rtsp feed from a onvif camera and then redistribute this stream to everyone that connects to my server.

I created a new Ubuntu 64-bit vm on VMware Workstation using this iso: https://www.ubuntu.com/download/desktop/thank-you?version=18.04.1&architecture=amd64

I then installed ubuntu-desktop:

$ sudo apt-get update
$ sudo apt-get install ubuntu-desktop
$ reboot

I cloned the gst-rtsp-server from its github repository to a folder on my desktop:

$ cd Desktop
$ mkdir camSrv
$ cd camSrv
$ git clone https://github.com/GStreamer/gst-rtsp-server.git

I then installed the dependency referenced by this post:

$ sudo apt-get install autoconf -y
$ sudo apt-get install automake -y
$ sudo apt-get install autopoint -y
$ sudo apt-get install libtool -y

but when i try to build the gst-rtsp-server project, I keep getting errors...

I installed a bunch of other dependencies, but now I'm stuck at the error:

configure: No package 'gstreamer-1.0' found
configure: error: no gstreamer-1.0 >= 1.15.0.1 (GSTreamer) found

I can't find what i'm missing... all i want is to make the example mentioned in this post work for me...
