How to stream media playing in songbird? - linux

Songbird is an open source media player with lot of plugins. I want to broadcast media playing on my songbird over a network. Kindly, do not suggest me using another player.

Use pulseaudio as your audio framework - it has support for acting as a streaming server. It can play to both your local speakers and a network destination simultaneously.

How to play RTSP stream from ip video camera and NVR on user web page

I want to play RTSP stream from ip video cameras (MP4, H264) on my intranet web page, I use React. I have 12 cameras and NVR.
I did not find a way to do this without an intermediate server (Webrtc is not suitable), that spends resources on transcoding h264 stream to the mjpeg.
If I set a high resolution and quality of the stream, then a lot of resources are spent on transcoding, and most importantly, the streaming of mjpeg images takes a lot of traffic.
Is there a way or solution to stream from the ip camera directly to the web page so that the decoding is on the user's webbrowser side.
This will free the intermediate server from a heavy load for big streams.
It is necessary that the playback work on mobile phones.
Thanks for the answer.
There is no way to stream RTSP camera's H264 video directly to web browser.
But cameras support outputting still jpeg images - you can create a webpage that will display such an image from a camera every 200ms or so.
If you are not happy with the above solution, you must use a media server in between, which will pull RTSP stream from the camera and will convert it to some protocol that browser understands. You are mistaken in one thing: no video transcoding is involved. I don't know why WebRTC is not an option for you, but most media servers will offer 4 types of output:
Low latency:
WebRTC
Websockets to MSE
High latency:
HLS
MPEG-Dash
All these methods do NOT require transcoding of your original H264 video, encoded by RTSP camera/NVR. Some media servers you can use: Unreal Media Server, Wowza, Janus.
Live demo: http://www.umediaserver.net/umediaserver/demos.html
No browser has native RTSP support, so if you want decoding to happen on the end user side, then you'll have to write your own custom web player.
You can start by looking at the open-source solution like this one:
git://github.com/Streamedian/html5_rtsp_player.git
It works on PC and Android, but didn't work with iPhone for me (but you can try it for yourself https://streamedian.com/demonstration/ maybe it's just my issue), but maybe you can find better alternative or fork it and make it work on all devices.
It still requires a middle-man proxy server though because it uses a websocket tech to work, but since it doesn't do any video converting or decoding, it don't suppose to take any resources at all.

Using ffmpeg to stream live video from a raspberry pi to a web server for distribution

I am trying to build a device that will encode h.264 video on a raspberrypi and stream it out to a separate web server in the cloud. The main issue I am having is most implementations I search for either have the web server directly on the pi or have the embedded player playing video directly from the device.
I would like it to be pretty much plug and play no matter what network I am on ie no port forwarding of any sort all I need to do is connect the device to the network and the stream will be visible on a webpage.
One possible solution to the issue is just simply encode frames in base 64 as jpegs and send them to a an endpoint on the webserver, however, this is a huge waste of bandwidth and wont allow for the framerate h.264 would.
Any idea on some possible technologies that could be used to do this?
I feel like it can be done with some websockets or zmq and ffmpeg somehow but I am not sure.
It would be helpful if you could provide more description of the architecture of the device. Since it is an RPI, it is probably also being used for video acquisition via the camera expansion port. If this is the case, you can access the video device and do quite a bit with respect to streaming using the combination of available command line tools.
Something like the following will produce an RTMP stream from the video camera host.
raspivid [preferred options] -o - | ffmpeg -i - [preferred options] rtmp://[IP ADDR]/[location]
From there, FFmpeg will do a lot of heavy lifting for you.
This will now enable remote hosts to access the RTMP stream.
Other tools that would complement that architecture may be ffserver where the rtmp stream from the rpi host could be acquired and then be made available to a variety of clients such as a player in a webpage. Quick look shows ffserver may be obsolete, but that there are analogous components.

RTP stream with bareSIP

my current setup involves streaming from a GoPro to a linux box, and I managed to get bareSIP running on the box to stream the video locally with the 'v' command. However, there's no documentation or commands to configure an RTP broadcasting stream. Would anyone have any insight into publishing an RTP/RTSP output stream for other users to view on their devices?
I've used Unreal Streaming Media components and found them to be very good. They are lightweight and fast yet very powerful.
Using Unreal components you could install the stream forwarder on your laptop, point it at the RTSP stream and tell it to forward to the Distribution server application.
This app can host thousands of connections (supposedly) and last I looked you didn't need a license if you have 3 or fewer sources. The stream can be viewd via their own small player app, via a web player such as jPlayer or via VLC etc.
I've been pretty happy with this before - it saved me from having to use the Live555 streaming mess.
Good Luck!

Two-way audio for software ip camera

I am trying to setup a raspberry pi box with a usb camera as a IP Camera that can be viewed from a a generic android IP Camera monitor app. I've found some examples on how to get the video stream, and that works, but what I also need is two-way audio. This seems to come out of the box in standalone network cameras -- any ideas how that works? I want to set it up in a way compatible with typical network cameras so that my cam can be used by any generic ip camera viewer app.
Well, the modern cameras nowadays implement the ONVIF protocol. This protocol specifies that you have a RTSP server that streams audio and video from the camera to the pc, but it also mandates a so called audio backchannel. It's a bit long to explain how it works, check it in the specs.
ONVIF is the standard, but you could also install an existing SIP client and do a video/audio VoIP call rather than implementing ONVIF - depends on the long term goals of your project.

Audio/video streaming to mobile browsers

I am developing a WAP/mobile website that would allow users to stream audio/video (although the priority is audio) via their mobile browsers..
For music I would be streaming mp3 files, and for video I would be streaming flv and 3gp files (but mostly 3gp).
Can anyone recommend solutions (i.e. what to use and/or a point to the right direction) to enable streaming audio/video to a mobile browser?
AFAIK, there is RTSP (probably via Darwin Streaming Server?) which is supported in most 3G devices, and flash lite. (Would using flash lite as a player even be a good idea, since the users would need to have flash lite installed on their mobile devices? I'm not that familiar with flash.)
Most mobile phones support video streaming via RTSP, and the cheapest method is the Darwin Stream Server, and it integrates with the Real Video player
As for flash lite that has limited handset support so I wouldn't recommend using it.
The only thing I would add is that without wireless carrier support streaming of data to a mobile phone can be very expensive for an end user, so please ensure that the end user knows about the potential data charges
