Changing streaming source (Webcam) from /dev/video0 to Internet Stream (syntax????)

[JR]

FYI,

I replaced the /dev/video in the japel.properties file with my Hava TV
streamer Webcam=queue v4l2src rtsp://192.168.1.230 ! video/x-raw-
yuv,width=160,height=120 ! ffmpegcolorspace ! videorate ! video/x-raw-
yuv,framerate=5/1 ! x264enc ! mux. { mpegtsmux name=mux !
tcpserversink port=PORT } { gconfaudiosrc ! queue ! audioconvert !
faac ! queue ! mux. }

Hava supports VLC's rtsp:// protocol. This doesn't work and I get the
error about /dev/video0 even though it was removed from the
configuration file.

Any ideas? My understanding was that an "internet stream" was
supported. Does this need to be an http:// or mms:// stream as a
source or can it also be rtsp://. My assumption whatever v4l
supported would work.

Thanks in advance,
JR

Hi JR,

You got it wrong.

You're trying to read a rtsp feed not a v4l2src device.

Is your webcam also providing sound? then if this is the case, you
should also modifiy the gstreamer configuration to get sound from the
webcam instead of your local

You should read the GStreamer documentation as there is a lot of
details on how to use the configuration: http://gstreamer.freedesktop.org/documentation/plugins.html

Here is a config from the console that you can test your webcam:

gst-launch-0.10 rtspsrc location=rtsp://192.168.1.230/ latency=0 !
decodebin ! ffmpegcolorspace ! autovideosink

Of course, you will have to check the proper URL as this example may
not work with your webcam. This will display your webcam in a small
window on your PC.

Once it is working, then you need to create a pipeline for JapelServer
that should look like this:

Webcam=queue rtspsrc location=rtsp://192.168.1.230/ latency=0 !
decodebin ! ffmpegcolorspace ! videorate ! video/x-raw-

yuv,framerate=5/1 ! x264enc ! mux. { mpegtsmux name=mux !
tcpserversink port=PORT } { gconfaudiosrc ! queue ! audioconvert !
faac ! queue ! mux. }

This one will assume that your webcam is providing sound also

Webcam=queue rtspsrc location=rtsp://192.168.1.230/ latency=0 !
decodebin name=dec ! ffmpegcolorspace ! videorate ! video/x-raw-

yuv,framerate=5/1 ! x264enc ! mux. { mpegtsmux name=mux !

tcpserversink port=PORT } { dec. ! queue ! audioconvert ! faac !
queue ! mux. }

That should get your going...

Patrick,

Thanks so much for your reply.  All testing is done on a single local private (192.168.1.0/24) subnet.

Using VLC player to open up rtsp://192.168.1.230 works perfectly.

Using your command, I get the following:
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
WARNING: from element /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0: Could not read from resource.
Additional debug info:
gstrtspsrc.c(3132): gst_rtspsrc_loop_udp (): /GstPipeline:pipeline0/GstRTSPSrc:rtspsrc0:
The server closed the connection.

When trying to stream a XVID video file or using the updated rtpsrc for Webcam, I click on the 500k or 50k video file or the webcam entry and the following is diplayed on the console.  VLC opens up but displays nothing

Any ideas? So far I haven't been successful with either an AVI (DIVX/XVID) file or the rtspsrc both via VLC player and via the iPhone on my local LAN.

Thanks,
JR

Just be make it easier, I decided to convert the AVI file to an iPhone
compatible format even though I assumed it would transcode the video.
I then tried again to open it up on my iPhone connected to my local
wireless LAN. Again it failed. I then updated my Ubuntu packages and
verified I have the full OpenJDK and all the Gstreamer pacakges
(running the latest version of Ubuntu from the Internet (32bit). It
still didn't work.

Here is the output from the console trying to open up the 50k link.
Quicktime on the iPhone just opens up and says "Loading Movies" and
never gets any further.

Any ideas? I really want to try to get this working. I realize this
is Alpha code but I haven't been successful in stream even the Video
files.

Thanks again,

Is you computer a fast one?  I am wondering it this could be the problem.  On my setup, it works but I can see that the player (iPhone or VLC) is trying to load the stream a few times before it really starts....

I'll have a look at the code.

Hi

I just updloaded to SourceForge a new version "Alpha4" which has the
latest code. I don't know why, but Alpha3 what not up-to-date to the
latest source code.

Tell me how it goes...
