I want to use the webcam on my laptop as video device on my pc to use it for video conferencing etc.
So I not just want to stream the video. I actually want to "stream" the entire device over network.
So, two computers, one streams its webcam, the other picks it up as video device.
Both computes run normal Ubuntu 18.04 however I will soon upgrade to 20.04
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/video1
$ v4l2-ctl --list-formats
ioctl: VIDIOC_ENUM_FMT
Index : 0
Type : Video Capture
Pixel Format: 'YUYV'

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

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 am trying to play screen in a VLC window. (To share-screen on chrome) When I try to capture screen with "Desktop" option it says:
Your input can't be opened: VLC is unable to open the MRL 'screen://'. Check the log for details.
In the popup window. I have tried enabling verbose logs, but nothing gets generated in the logs either. I am using KDE. If it helps, the same used to work when I was running mint+cinnamon on this same machine.
I'm looking for a way to stream to YouTube Live on my computer. I know there are various tools available for Windows, but I haven't found anything for Linux. I prefer not to use G+ Hangouts, but go right to actual streaming. Does anybody know of any tools for Linux that will stream to YouTube Live, or is there a Windows tool that works without any issues under WINE?
Is there a way to stream audio or video to an Apple Airplay device?
I have an Aiprort Express that can play audio, but the same question applies to the Apple TV or any other Airplay device.
It is really easy to do this in iTunes and I was wondering if there is a way to do it on ubuntu?
