I have setup OBS on Ubuntu. I have virtual webcam working on OBS with Streamyard.
However, I am not able direct audio from OBS into Streamyard/Chrome browser. I need a software/virtual microphone. Has anybody found a straight forward solution?
Thank you in Advance.

I create web app with Ruby on Rails using WebRTC for video connections (with SimpleWebRTC: https://simplewebrtc.com/). It works on remote server, and use signalmaster (https://github.com/andyet/signalmaster). Everything works good on most networks, but sometimes there is no remote video. I have callback from videoAdded, but there is completely no video from other peers. I think it might be something with that network configuration, but have no idea what. Does anyone have idea what's wrong?
I am trying out VOD streaming with latest VLC as described in this wiki:
https://wiki.videolan.org/Documentation:Streaming_HowTo/VLM/ and trying to stream an HD movie file with extension mp4.
i am able to open the stream in VLC running on the same machine, but it takes lot of time to even start playing back. (minutes). The test is run in Fedora 20.
My machine is capable enough to play HD video.
I have tried with and with trans-coding and results are same.
Help is appreciated.
Found the issue and it is strange.
I had the streaming server and client in the same machine. The streaming was always extremely slow. However, disconnecting from the network made it work fast.. It did not matter whether the network connection was wifi or ethernet.
However, if you were to run the client in a different machine, it work properly.
First of all you have to understand a bit about my background. I have never worked with IP cameras before, but I will have to access multiple IP cameras simultaneously with OpenCV very soon. Apart from that, my network knowledge is not that much good.
Now the question. I know OpenCV can access IP cameras using its URL with the help of VideoCapture. There are number of questions in StackOverflow as well. But, the IP address is something that can be changed by time to time, it is dynamic. So even in a IP cam, the IP will change by time to time. So if this is the case, does this mean every time you try to access the cameras with OpenCV, you have to find the IP address of the camera manually and change the URL in OpenCV as well? I do not need to access the cameras via the internet, accessing locally is fine, via Wifi or network cables. How can I set a fixed IP address/ URL so the OpenCV code has nothing to change every time?
PS: I navigated through lot of websites (sites from more than 5 result pages of Google search) but the answers given are either too old or not that much convincing. So I decided to walk into StackOverflow for the answer.
If you can use local network, then Yes, you should use fixed IP address....if the Camera SDK is compatiable with OpenCV this you dont have have to worry about this and you can call VideoCapture directly. Or, you could use the camera SDK to get frames directly and then copy these frames to opencv image format and use opencv. This should not be too complicated.
If your router has a DHCP reservation feature, simply tell the router to always give an IP camera a certain IP.
Thus when the camera polls the DHCP server when it connects to the network, it will automatically receive its reserved IP. Other clients without a reservation will simply receive a random IP like normal. You might even think about doing this for all your computers and devices; it's quick and easy.
I have a really high quality RTSP feed coming into a windows server. I'm attempting to use VLC to restream it as Http Live Streaming.
Does anyone know whether it is possible to establish this stream through VLC's graphic user interface as opposed to the command line? If so, how?
The examples I've found so far (on here and elsewhere) have all been command line examples and none of them have worked at all.
I would love to hear from anyone who has actually accomplished a successful restream of RTSP to an http live stream using a windows server. Incidentally, I already have the website set up to serve the result, but I can't get the stream to write the .ts files regardless of what I've tried.
I'm stumped. Thanks.
just look this command for example:
vlc -I dummy rtsp://ip:port/blablabla--sout '#transcode{vcodec=h264,fps=20,vb=512,scale=1,acodec=none,venc=x264{aud,profile=high,level=60,keyint=15,bframes=0,ref=1,nocabac}}:duplicate{dst=std{access=livehttp{seglen=10,delsegs=true,numsegs=10,index=/var/www/live/mystream.m3u8,index-url=http://ip/live/mystream-########.ts},mux=ts{use-key-frames},dst=/var/www/live/mystream-########.ts},dst=std{access=http,mux=ts,dst=:8082/video.mp4}}'
My project is to capture images and process them to move a wheelchair accordingly. I am using Nexys2 FPGA board for this purpose. Nexys2 has a usb port and the camera is also a usb camera. but i dont have the drivers in verilog which will make nexys2 and the camera communicate with each other. Please help me ill be very grateful.
Well, if you manage to write a driver for a USB camera in VErilog, you can sell that for a lot of money :)
Well, sarcasm aside, there is NO WAY you can access a USB camera in Verilog, unless you have a USB host implemented in your FPGA and have a CPU controlling it and have a SW driver for that camera.
There are alternatives to this, you can buy a camera which has an FPGA "friendly" connector like this one:
5 Mega Pixel Digital Camera Package
Which comes with the Verilog code that you can use in your project.
Sadly, the USB port on the Digilent Nexus 2 board does not have host capabilities, it can only act as a USB slave. The USB connection on the board is used for powering the board and configuring the FPGA and other onboard peripherals.
The newer Nexus 3 board has a second USB port however it has the same issue in that it can only act in slave mode. Also due to the configuration can only be used for mouse and keyboard input.
