I have a rtsp-simple-server running on Debian and
I try to publish RTSP from my ip camera (h264 + pcm ulaw) to RTSP server with gstreamer.
I tried this command:
gst-launch-1.0 rtspsrc location=rtsp://192.168.1.1:554/11 !
rtph264depay ! rtspclientsink location=rtsp://server.com:8554/camstream1 protocols=tcp
It works, but it streams video only. The following command streams audio only:
gst-launch-1.0 rtspsrc location=rtsp://192.168.1.1:554/11 !
rtppcmudepay ! rtspclientsink location=rtsp://server.com:8554/camstream1 protocols=tcp
How can I stream video + audio?
Try this (or something like this) :
gst-launch-1.0 rtspsrc location=rtsp://192.168.1.1:554/11 name=mysrc !
rtph264depay ! rtspclientsink location=rtsp://server.com:8554/camstream1 protocols=tcp mysrc. ! rtppcmudepay ! rtspclientsink location=rtsp://server.com:8554/camstream1 protocols=tcp
OR you might have to MUX the audio and video first, before sending to rtspclientsink (this part is beyond me)
Try this first on a PC to see if the first part works
gst-launch-1.0 rtspsrc location=rtsp://192.168.1.1:554/11 name=mysrc !
rtph264depay ! autovideosink mysrc. ! rtppcmudepay ! autoaudiosink

I'm using the following pipeline to listen to a RTSP stream and save a video file:
gst-launch-1.0 -q rtspsrc location=rtsp://<ip>:<port>/video ! decodebin ! autovideoconvert ! x264enc pass=5 quantizer=25 speed-preset=6 ! h264parse ! matroskamux ! filesink location=<filename>
But even though I can see the files generated, they lack the duration of the video when playing on VLC.
I can fix it by passing it through ffmpeg later, but I want to generate the video from gstreamer already completely valid. How can I fix this pipeline?
gst-launch-1.0 -e rtspsrc location=rtsp://<ip>:<port>/video ! decodebin ! videoconvert ! x264enc ! mp4mux ! filesink location="filename.mp4"
This will create a video with duration shown correctly
I have a third party application that reads data from a thermal camera and generates a RTP stream to a given UDP source. I am trying to wrap this RTP into a RTSP stream but I am running into problems...
The third party application basically runs gstreamer with this command
appsrc format=GST_FORMAT_TIME is-live=true block=true caps=video/x-raw,width=640,height=480,format=GRAY8,clock-rate=90000,framerate=10/1 ! openjpegenc ! rtpj2kpay ! udpsink host=127.0.0.1 port=3000
Using the command below I can visualize the stream on my machine
gst-launch-1.0 udpsrc port=3000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)JPEG2000, sampling=(string)GRAYSCALE, width=(int)640, height=(int)480, payload=(int)96" ! queue ! rtpj2kdepay ! openjpegdec ! videoconvert ! xvimagesink
However when trying to use the default RTP to RTSP application example using https://github.com/freedesktop/gstreamer-gst-rtsp-server/blob/master/examples/test-launch.c to just forward it with a RTSP container the connection fails with VLC. Command below:
./rtp-src-to-rtsp '( udpsrc port=3000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)JPEG2000, sampling=(string)GRAYSCALE, width=(int)640, height=(int)480, payload=(int)96" ! queue ! rtpj2kdepay ! rtpj2kpay )'
Any light on what I am doing wrong? VLC gives only a non-descriptive error
live555 error: Nothing to play for rtsp://{IP}:{PORT}/test
It might be a lack of support of J2K in VLC (I'm using revision 3.0.8-0).
Simulating your source with:
gst-launch-1.0 videotestsrc ! video/x-raw,width=640,height=480,framerate=10/1,format=GRAY8 ! openjpegenc ! rtpj2kpay ! udpsink host=127.0.0.1 port=3000
and relaying as RSTP with:
./test-launch "udpsrc port=3000 auto-multicast=0 ! application/x-rtp,encoding-name=JPEG2000,sampling=GRAYSCALE ! queue ! rtpj2kdepay ! image/x-jpc ! jpeg2000parse ! rtpj2kpay name=pay0 "
works on Linux with X using:
gst-launch-1.0 rtspsrc location=rtsp://127.0.0.1:8554/test ! application/x-rtp, encoding-name=JPEG2000,sampling=GRAYSCALE ! rtpj2kdepay ! jpeg2000parse ! openjpegdec ! videoconvert ! xvimagesink -v
Though, I haven't been able to receive with VLC, nor able to make a correct J2K/RTP SDP for VLC nor ffmpeg. Someone better skilled may further advise.
I can successfully stream HD video using following pipelines:
streame server:
gst-launch-1.0 filesrc location="Gravity.2013.720p.BluRay.x264.YIFY.mp4" ! decodebin ! x264enc ! rtph264pay pt=96 ssrc=0 timestamp-offset=0 seqnum-offset=0 pt=96 ! gdppay ! tcpclientsink host=192.168.1.93 port=5000
client:
gst-launch-1.0 tcpserversrc host=192.168.1.93 port=5000 ! gdpdepay ! rtph264depay ! decodebin ! autovideosink
I want to add the audio stream too.
I guess it is possible to use a different port and tcpserver/tcpclient combination to stream audio parallel to video. But I am not certain, how gstreamer would synchronize two streams properly to play the movie in the client end. Apart from this method, are there any other methods? such as muxing two streams before and demuxing it in client end?
I'm really running out of ideas. Here is my problem: I need to stream on demand mp4 (H264) through the network. I'm new with gstreamer and after lot of tries with versions > 1.0 I decided to use 0.10 because seems to be most promising so far.
Command below works perfect ( I see window with my movie )
gst-launch filesrc location=/home/zuko/sintel_trailer-368p.mp4 ! decodebin2 name=dec ! queue ! ffmpegcolorspace ! autovideosink dec. ! queue ! audioconvert ! audioresample ! autoaudiosink
Now I'm trying to build TCP stream using commands (so far on localhost only):
Server side:
gst-launch filesrc location=/home/zuko/sintel_trailer-368p.mp4 ! decodebin2 name=dec ! tcpserversink host=127.0.0.1 port=5000
Client side:
gst-launch tcpclientsrc host=127.0.0.1 port=5000 ! decodebin2 name=dec ! queue ! ffmpegcolorspace ! autovideosink dec. ! queue ! audioconvert ! audioresample ! autoaudiosink
But response from the "client side" command is following:
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstDecodeBin2:dec/GstTypeFindElement:typefind: Could not determine type of stream.
Additional debug info:

What is missing, or what I'm doing wrong?
I'm testing on: VirtualBox 4.3.12 with Ubuntu 14.04, kernel 3.13.0-24-generic #47-Ubuntu SMP Fri May 2 23:30:00 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

First off, using 0.10 is an absolutely bad idea, you should really stick to 1.0, for which you will have community support.
Second, to your problem itself, you are trying to stream the decoded stream over the network ("decodebin2 ! tcpserversink") and to decode it again on the other side ("tcpclientsrc ! decodebin2"). Not only is it very wrong with respect to bandwidth usage, it also straight up won't work.
I'll advise you to have a look at the rtp plugins provided by gstreamer.
Using gstreamer 1.0 the server side can share h264 streams with:
gst-launch-1.0 filesrc location="C:\\Videos\\videotestsrc.avi" ! decodebin ! x264enc ! mpegtsmux ! queue ! tcpserversink host=127.0.0.1 port=8080
While the client side receives with:
gst-launch-1.0 tcpclientsrc host=127.0.0.1 port=8080 ! decodebin ! videoconvert ! autovideosink sync=false
Alternatively, the client could be simulated with VLC through:
Media >> Open Network Stream >> tcp://127.0.0.1:8080 >> Play
I'm having a problem trying to record audio+video from my webcam to a file. If I use videotestsrc and autoaudiosrc I get everything right (read as in I get a file with audio recorded from the webcam's mic, and test-video image), but as soon as I replace videotestsrc with v4l2src (or autovideosrc) I get Error starting streaming on device '/dev/video0'.
The command I'm using:
gst-launch-0.10 videotestsrc ! queue ! ffmpegcolorspace! theoraenc ! queue ! oggmux name=mux autoaudiosrc ! queue ! audioconvert ! vorbisenc ! queue ! mux. mux. ! queue ! filesink location = test.ogg
Why is that happening? What am I doing wrong?
EDIT:
In fact, something as simple as
gst-launch-0.10 autovideosrc ! autovideosink autoaudiosrc ! autoaudiosink
is failing with the same error (Error starting streaming on device '/dev/video0')
Replacing autovideosrc with videotestsrc gives me test image + real audio.
Replacing autoauidosrc with audiotestsrc gives me real image + test audio.
I'm starting to think that this is some kind of limitation of my webcam. Is that possible?
EDIT:
GST_DEBUG=2 log here: http://pastie.org/4755009
EDIT 2:
GST_DEBUG="v4l2*:5" (gstreamer 0.10): http://pastie.org/4810519
GST_DEBUG="v4l2*:5" (gstreamer 1.0): http://pastie.org/4810502
Please do a
gst-launch-1.0 v4l2src ! videoscale ! videoconvert ! autovideosink
Does that run? If not repeat as
GST_DEBUG="v4l2*:5" GST_DEBUG_NO_COLOR=1 gst-launch 2>debug.log ...
and check the log for errors. You also might want to run v4l-info (install v4l-conf under debian/ubuntu) and report what formats your camera supports.
