Do you guys have any suggestions on free/paid solutions for recording video from webcam and storing it on the wowza media server? I tried the wowza recording example but I couldn't figure out how I can set the server connection as a variable.
Thanks!
Try HDFVR, a paid flash application, but very good.
The wowza recording example should work for this. When you say you couldn't "figure out how to set the server connection as a variable", is that from the client to tell Wowza to record, or to play back the already recorded stream? Using the built-in http provider here http://www.wowza.com/forums/content.php?123 will allow you to make post requests to the Wowza server to start and stop recording.

I don’t know if I can say “I’m sorry for ask” but I spent more than a week looking for a solution without success. I have a Jetson Nano and with OpenCV I get and process an image at 4fps, I need to send this video to a web server to allow the client connected to the server get the video. Everything need to be written in C++.
Because a need a low latency I did test with GStreamer and WebRTC without success. I don’t have any web server ready, so I can use any implementation.
Anyone know where I can find some example implementation with this schema?
You can use mediasoup to send data to the server to then send the stream with rtp to another endpoint like gstreamer or ffmpeg.
Here is a recording project where data is sent from the browser -> server -> gstreamer -> file.
Mediasoup is written in c++ and has a wrapper for js.
I had similar problem and used such example from GStreamer WebRTC official repo. It's written in Python for Janus Gateway video rooms but I think it can be easily rewritten in C++ as you need.
In the code for OpenCV, I used V4L2Loopback as a virtual output device to be used as input for GStreamer WebRTC example.
I hope such approach may help you.
I think no need to send it to a Web Server. In Gstreamer examples [https://github.com/GStreamer/gst-examples]. The SendOnly example sends a video to a Web Client Using WebRTC. You can modify it to send an OpenCV mat.
I am working on a live-streaming prototype, I have been reading a lot about how live-streaming works and many different approaches but I still can't find a live-streaming stack that suits my needs...
These are the requirements for my prototype:
1)The video/audio recording must come from a web browser using the webcam, the idea is that the client preferably shouldn't need to install plugins or do anything complicated(maybe installing Flash player plugin is acceptable, only for recording the video, the viewers should be able to view the stream without plugins).
2)It can't be peer to peer since I also need to store the entire video in my server (or in Amazon s3 servers for example) for viewing later.
3)The viewers should also be able to watch the stream without the need of installing anything, from their web browsers, say Chrome and Firefox for example. We want to use the HTML5 video tag if possible.
4)The prototype should be constructed without expending money preferably. I have seen that AWS-Cloudfront and Wowza offer free trials so we are thinking about using these 2 services.
5)The prototype should be able to maintain 1 live stream at a time and 2 viewers, just that, so there are no restrictions regarding this.
Any suggestions?
I am specially stuck/confused with the uploading/encoding video part of the architecture(I am new to streaming and all the formats/codecs/protocols/technologies are making it really hard to digest).
As of right now, I came across WebRTC that apparently allows me to do what I want, record and encode video from the browser using the webcam, but this API only works with HTTPS sites. Are there any alternatives that work with HTTP sites?
The other part that I am not completely sure about is the need for an encoding server, for example Wowza Streaming Engine, why do I need it? Isn't it enough if I use for example WebRTC for encoding the video and then I just send it to the distribution service (AWS-Cloudfront for example)? I do understand that the encoding server would allow me to support many different devices since it will create lots of different encodings and serve many different HTTP protocols, but do I need it for this prototype? I just want to make a 1 format (MP4 for example) live-stream that can be viewed in 2 web browsers, that's all, I don't need variety of formats nor support for different bandwidths or devices.
Base on your requirement, WebRTC is good way.
API only works with HTTPS sites. Are there any alternatives that work
with HTTP sites?
No. Currently Firefox is only browser is allow WebRTC on HTTP, but finally it need HTTPS
For doing this prototype you need to go with the Wowza WebRTC.
While going with wowza all the streams are delivered from the wowza only.So it become a routed WebRTC.
Install Wowza - https://www.wowza.com/docs/how-to-install-and-configure-wowza-streaming-engine
Enable the WebRTC - https://www.wowza.com/docs/how-to-use-webrtc-with-wowza-streaming-engine
Downaload and configure the Streamlock. or Selfsigned JKS file - https://www.wowza.com/docs/how-to-request-an-ssl-certificate-from-a-certificate-authority
Download the sample WebRTC - https://www.wowza.com/_private/webrtc/
Publish stream using the Publish HTML and Play through the Play HTML ( Supported Chrome,Firefox & Opera Browsers)
For MP4 files in WebRTC : you need to enable the transcoder with h264 & aac. Also you need to enable the option Record all the incoming Streams in the properties of application which you are creating for the WebRTC ( Not the DVR ).Using the File writer module save all the recorded files in a custom location.By using a custom script(Bash,Python) Move all the Transcoded files to the s3 bucket, Deliver through cloudfront.
Is it possible to use the WebRtc Offline. When we connect 2 devices through peer to peer connection After that WebRtc for streaming the video Which we want to set it through offline which we don't want to use the internet for every time. Is this Method is possible to Implement using WebRtc.
How can We set the Quality of the Video using WebRtc. Every time it Works as its Default Quality Streaming. How can we Improve Its Quality.
https://github.com/Mahabali/BonjourWebrtc
I just gone through the Link it is pretty good using WebRtc and Peer to peer Connection. But if the Internet is not their it is not Work. How can I overcome this Problem. Is it possible to set Offline using WebRtc and How I improve the Quality of the Video.
Sorry For my Bad English hope anyone help me to overcome this.
As explained on the blog of the BonjourWebRtc project : https://mobilitysolutionsexpert.wordpress.com/2016/05/04/server-less-or-no-server-webrtc-ios-app/, it used a Google Stun server.
So if you want to used it offline, you have to host your own Stun server on a local server. You can easily find code for Stun server on the web, juste google it.
I am an absolute beginner with this. I installed Wowza and wanted to play VOD. The test works, the sample.mp4 plays. However when I try what looks like the same URL shown in the test player, which in my case is:
http://192.168.5.76:1935/voddec8/mp4:sample.mp4/manifest.f4m
I get the contents of the manifest. When I try to remove the manifest.f4m so that the URL is just:
http://192.168.5.76:1935/voddec8/mp4:sample.mp4
EDIT: Could it be that I need to be in a player, not a browser?
I just get info about the Wowza server:
Wowza Streaming Engine 4 Trial Edition (Expires: Jun 07, 2016) 4.3.0 build16025
What am I doing wrong?
Wowza does not support progressive download (meaning basic http download), you can do that with any web server. Then you could open something like this in the browser http://192.168.5.76:1935/voddec8/sample.mp4
If you want to play an HLS stream (playlist.m3u8) or HDS (manifest.f4m) you need to call it through a player that supports those protocols, like Jwplayer, Flowplayer,... or an application like VLC. Mobile devices (iphones, and moder Android should open HLS stream directly though.
You can also open the stream using rtmp, but you need a player (flash based) using an url like this rtmp://192.168.5.76:1935/voddec8/mp4:sample.mp4
You need to check what is the protocol best suited for you.
if you want to deliver the vod as progressive method , you can try nimble streamer (wmspanel.com)
which will gives you additional security for progressive delivery method, and if this is for web delivery i prefer to deliver using hls method (.m3u8) which is the best method to avoid your sever bandwidth also.
If you have installed wowza on local system, the URL pattern will be your IP address. You can switch wowza to listen on any port (should be open port).
Ex: rtmp://10.136.15.1:1935/vod/mp4:bunny.mp4
Instead of running it under 1935, you can switch it to listen on port:80.
You can try running your vod video in VLC player, as highlighted below.
Once this is running, you can embed it in your application using open source media player (strobe player) : http://matbury.com/strobe/
Does Wowza Streaming Server (used as live streaming services) care about the direction of data stream?
Possibility of Wowza Server as a server side mode and client side mode
Since I am trying to send data stream via LTE, the cost of sending data stream is very high. So I am wondering if it is possible to have live stream data only when the request is present.
Thank you
It's not 100% clear what do you mean by "Wowza acting as a client" to me. Wowza can be configured to be an edge instance, that pulls stream from an origin Wowza server, when you want to have multiple, possibly geographically distributed stream sources.
Or, if you think about the other case, Wowza accepts the stream from encoders, in which case the data flow direction is also towards Wowza. This is the case when you install for example a Flash Media Live Encoder, or a VLC and push your encoded stream "into" Wowza, which then distributes this stream to all other players.
But obviously Wowza won't act as a video player to you.. :-)
Can you clarify your first question, maybe I can give a better answer then.
