Simulating a IP camera (MJPEG)

Hi,
I'm working on some sort of surveillance project for my thesis. As a first step I want to simulate an IP camera with GStreamer that outputs MJPEG. I'm trying to do this: gst-launch-0.10 videotestsrc ! ffmpegcolorspace ! jpegenc ! multipartmux ! tcpserversink port=3000 And then load this little HTML snippet into firefox: <html> <head> <title>Gstreamer testing</title> </head> <body> <h1>Testing a dummy camera with GStreamer</h1> <img src="http://localhost:3000" class="" alt="" /> <hr /> </body> </html> That won't do it, since it's only doing output to a TCP port, but it does not do it with proper HTTP headers and I believe that's why firefox won't understand this stream. Is there a plugin that can do that (encapsulate data, like MJPEG) into a proper HTTP stream? -- -- Noe Nieto

I'm trying to do something like that ..
i have a pipeline like this appsrc ! queue ! videoparse format=14 width=%d height=%d ! videorate " " ! videoscale ! video/x-raw-rgb,width=320,height=240 " " ! queue ! ffmpegcolorspace ! queue ! jpegenc ! multipartmux ! queue " " ! tcpserversink port=5000 sync=false but i can't find anything to use this stream in some browser ... ... I'm trying to do with rtp and udpsink, this seems to work in the "server" but in the client side i can't see anything... so.. it's possible to use tcpserversink to stream and see in a browser?

if there is no HTTP server sink for GStreamer, then there are other
options. Are you running Apache? Do you have PHP? It would be pretty trivial to write a PHP script that connects to your gst-launch process on port 3000 and begins streaming data from it to the HTTP client connected to Apache (firefox) On Wed, Apr 6, 2011 at 1:39 AM, Noe Nieto [http://percepcionunitaria.org]] <[hidden email]> wrote: > Hi, > > I'm working on some sort of surveillance project for my thesis.

Firefox handles MJPEG streams natively. As far as I've seen, the MJPEG stream should be "canned" into a HTTP multi-part stream. That's exactly what my pipeline below is lacking.
My app is being written in Python. So there's no PHP. But how do you dissasemble the multi-part in PHP? -- Noe 2011/4/6 Donny Viszneki <[hidden email]> if there is no HTTP server sink for GStreamer, then there are other -- -- Noe Nieto

I don't see any gstreamer plugin to encode stuff in multipart streams.
It seems like we don't have another option but to implement the HTTP-Multipart encoding/canning or write a gstreamer plugin for that. --- Noe 2011/4/6 Matias Hernandez Arellano <[hidden email]> I'm trying to do something like that .. -- -- Noe Nieto

found this old convo
http://gstreamer-devel.966125.n4.nabble.com/http-sink-element-td1047973.html Rygel can stream media to HTTP clients from a GStreamer source element (which could be a bin containing lots of elements). This source element is either provided by the MediaServer plugin or created by Rygel for transcoding.

You can use multifdsink to stream over http: simply add the file
descriptor of the connected client to multifdsink, I developed an application similar to what you need using multifdsink and it works fine.

There isn't a pipeline to demostrate this you have to write a gstreamer application. I have a working app that do this (and much more) in c++ you can also take a look at flumotion for insipiration it use multifdsink to stream ogg/theora over http, Nicola > > -- > Noe > > Nicola > > Il giorno mer, 06/04/2011 alle 12.28 -0400, Donny Viszneki ha > scritto: > > > found this old convo > > > > > http://gstreamer-devel.966125.n4.nabble.com/http-sink-element-td1047973.html > > > > Rygel can stream media to HTTP clients from a GStreamer > source > > element (which could be a bin containing lots of elements). > This > > source element is either provided by the MediaServer plugin > or created > > by Rygel for transcoding. > > > > Source code at: > http://git.gnome.org/browse/rygel/tree/src/rygel/ > > > > On Wed, Apr 6, 2011 at 12:18 PM, Noe Nieto > > [http://percepcionunitaria.org]] <[hidden email]> wrote: > > > > > > > > > 2011/4/6 Donny Viszneki <[hidden email]> > > >> > > >> On Wed, Apr 6, 2011 at 11:52 AM, Noe Nieto > > >> [http://percepcionunitaria.org]] <[hidden email]> > wrote: > > >> > Firefox handles MJPEG streams natively.

That narrows down the problem :) Maybe the solution would be tu "subclass" the tcpserversink and "decorate" the frames with tcp headers. Does that sound feasible in GStreamer? -- Noe
