Gstreamer 1.0 for raspbian

[gkreidl]

Can I use Gstreamer1.0 in midori or other browser?

It's used by the new webkit3 engine to display videos inside the browser (epiphany, kweb3).

Hello,

I am pretty new to using the camera module and gstreamer so please bare with me.

My goal:
To get one model b+ streaming video with gstreamer onto it's own display AND have a SECOND model b+ viewing the stream on a second stream

What I have accomplished:
1) Fresh install of raspbian on both pi's, successful install of gstreamer on both ends
2) both pi's set with static ip's and able to communicate. hooked up to a switch and not a router
3) camera is functioning with raspivid by itself

My problem:
After using this line on the pi WITH the camera

Code: Select all

raspivid -n -w 1280 -h 720 -b 4500000 -fps 30 -vf -hf -t 0 -o - | gst-launch-1.0 -v fdsrc ! h264parse ! rtph264pay config-interval=10 pt=96 ! udpsink host=10.3.99.33 port=9000

It spits out a bunch of code, and ends with

Code: Select all

Pipeline is PREROLLED..
Setting pipeline to PLAYING...
New clock: GstSystemClock

And then sits there and nothing else happens. The led on the cam is on, and the ethernet light is blinking. No video is shown on the screen.

I use the following code on the receiver pi:

Code: Select all

gst-launch-1.0 -v udpsrc port=9000 caps='application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264' ! rtph264depay ! video/x-h264,width=1280,height=720,framerate=30/1 ! h264parse ! avdec_h264 ! videoconvert ! autovideosink sync=false

This will generate a few more lines of code on the second pi, where i can see 'Setting pipeline to PLAYING...', but once again it will stop after displaying

Code: Select all

New clock: GstSystemClock

Once again I reiterate that I'm quite new at this streaming game, but I have been messing around for 10's of hours trying to figure this out.

Once again, my endgame is to have one pi (connected to the camera) displaying a constant feed on the screen, and also pipelining a stream to a SECOND pi to also view the same stream.

If anyone would be kind enough to point me in the right direction or point out one of my probable beginners errors, it would make my week!

Thank you very much!

Try first with a test source

something like:

Code: Select all

gst-launch-1.0 videotestsrc ! \
 jpegenc ! \
 rtpjpegpay ! \
 udpsink host=127.0.0.1 port=5200

And on the receiver:

Code: Select all

gst-launch-1.0 udpsrc port=5200 ! \
 rtpjpegdepay ! \
 jpegdec ! \
 autovideosink

See if that does anything. If you are new gstreamer or streaming in general read this:
http://www.z25.org/static/_rd_/videostr ... index.html

[codestar02]

It seems to be doing the same thing...

On camera side:

Code: Select all

Setting pipeline to PAUSED...
Pipeline is PREROLLING...
Pipeline is PREROLLED...
Setting pipeline to PLAYING...
New clock: GstSystemClock

No LED on the cam

On receiver side:

Code: Select all

Setting pipeline to PAUSED...
Pipeline is live and does not need PREROLL...
Setting pipeline to PLAYING...
New clock: GstSystemClock

I may be misunderstanding how gstreamer is supposed to work, is the feed supposed to show up on the screen as soon as I enter the command? I am getting no picture on either either Pi

Thanks

[sphaero]

Try the following:

Code: Select all

gst-launch-1.0 -v  videotestsrc ! autovideosink

This should give you a test video.
If it doesn't try:

Code: Select all

GST_DEBUG=4 gst-launch-1.0 -v  videotestsrc ! autovideosink

You'll see more debug output.
If you're running Xorg I think it should work with this:

Code: Select all

gst-launch-1.0 -v  videotestsrc ! ximagesink

If you run from command line you need the glimagesink or eglessink (or something called like that)
Run gst-inpect-1.0 to find out which modules... Again read the doc I send you to know what that's all about.
You also need to know what version of gstreamer you are running:

Code: Select all

dpkg -l | grep gstreamer

[codestar02]

Test video works on each pi, and i am able to ping each one so i know that they are able to communicate. After reading through and trying the Gstreamer document examples, I cannot seem to get any of the sent pipelines from one pi to show jpegs or video on the second pi

Thank you for bearing with me and my novice level problems

FINALLY got it streaming!

However, the video is extremely choppy, laggy, and fragmented. Is there a way to speed this up? Right now i'm seeing around 4 seconds of delay, and quick movements turn the screen to a mass of blocks.

My goal is an infinite stream onto a second, overclocked b+ pi, that does nothing else but view the video.

Sending line:

Code: Select all

raspivid -f -b 10000000 -fps 30 -t 0 -o - | gst-launch-1.0 -v fdsrc ! h264parse! rtph264pay config-interval=1 pt=96 ! udpsink host=10.3.99.255 port=9000

Thanks

[loadbang]

Thanks for the pointer. I missed some sources indeed.
Just tested and it is much smoother although gstreamer takes quite some overhead. 50% cpu compared to 3-7%. Anybody got lower cpu burden?

Did you fully remove the packages installed by the byvontaene.de-repository prior to dist-upgrade ?

How would one do this?

[sphaero]

sudo apt-get remove --purge gstreamer1.0*
sudo apt-get update && sudo apt-get dist-upgrade

[paul_espinosa]

hello i installa a precompilated version on my raspberry pi b+ with rasbian ...i also installed qt 4 ...but now a need use gsstreamer on qt ...

my file.pro
INCLUDE PATH += /usr/lib/arm-linux-gnueabiht/gstreamer-1.0
LIBS += -L/ /usr/lib/arm-linux-gnueabiht/gstreamer-1.0
LIBS += -lglib-2.0 -lpthread -lgstreamer-1.0 -lgobject-2.0 -lgmodule-2.0 -lgthread-2.0 -lrt
and in the main.cpp
#include <gst/gst.h>
but show this error gst/gst.h no such file or directory
how i can writhe or use correctly this libs ????
i need play mp3 in my raspberry in an aplicacion

Install the -dev packages

I have followed the instructions and wanted to use the Gstreamer in order to encode video from jpg files I have (TimeLapse). However when I run

Code: Select all

gst-launch-1.0 -e multifilesrc location="image_%04d.jpg" ! image/jpeg, framerate=12/1 ! decodebin ! video/x-raw, width=1296, height=976 ! progressreport name=progress ! omxh264enc target-bitrate=15000000 control-rate=variable ! video/x-h264, profile=high ! h264parse ! mp4mux ! filesink location=test.mp4

I am getting this return

Code: Select all

Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...
ERROR: from element /GstPipeline:pipeline0/GstMultiFileSrc:multifilesrc0: Internal data flow error.
Additional debug info:
gstbasesrc.c(2867): gst_base_src_loop (): /GstPipeline:pipeline0/GstMultiFileSrc:multifilesrc0:

ERROR: pipeline doesn't want to preroll.
Setting pipeline to NULL ...

I have no clue where to search. Any help is more than welcome

[Defiant]

Above packages are outdated, please use the ones in raspbian instead.

[nitschkecm]

Ok I will give it a try on a fresh raspbian install. Thanks for the update.
Should I just use the

Code: Select all

sudo apt-get install gstreamer1.0

or is there anything else needed especially if I want to use the gstreamer to create the video of time-lapse jpg

Raspbian latest should include the latest gstreamer, that is why you should be wary of old posts

Code: Select all

sudo apt-get update
sudo apt-get dist-upgrade

Hi

just tried that but I cannot run commands like

Code: Select all

gst-launch-1.0 -e multifilesrc location="image_%04d.jpg" ! image/jpeg, framerate=12/1 ! \
decodebin ! video/x-raw, width=1296, height=976 ! progressreport name=progress ! \
omxh264enc target-bitrate=15000000 control-rate=variable ! video/x-h264, profile=high ! \
h264parse ! mp4mux ! filesink location=test.mp4

to create a time-lapse video. Therefore I assume that I cannot use the standard version which is supplied now with Raspbian. do you have any good suggestion on how to make use of gstreamer and hw acceleration in order to encode time-lapse videos ?

[Defiant]

You should ask this in a separate, not dead thread.

mp4 over udp/rtp

Building gstreamer pipelines really feels like making blind guesses so far. Is there some essential documentation that i missed?
I've spent hours and hours trying to stream a 720p mp4 file from a master Raspberry PI 2 to two slave Raspberry's (synchronously).

My best semi-working pipelines:

Code: Select all

// server
gst-launch-1.0 -v filesrc location=video.mp4 ! qtdemux ! video/x-h264 ! rtph264pay ! udpsink host=192.168.0.255 port=5000
-or
gst-launch-1.0 -v filesrc location=video.mp4 ! qtdemux ! queue ! rtph264pay ! udpsink host=192.168.0.255 port=5000

// client
gst-launch-1.0 -v udpsrc port=5000 caps = 'application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264, sprop-parameter-sets=(string)"Z2QAH6zZQFAFuhAAAAMAEAAAAwPA8YMZYA\=\=\,aOvssiw\=", payload=(int)96, ssrc=(uint)36838312, timestamp-offset=(uint)1359991347, seqnum-offset=(uint)58019' ! rtpjitterbuffer latency=1000 ! rtph264depay ! decodebin ! videoconvert ! eglglessink
-or
gst-launch-1.0 -v udpsrc port=5000 caps="application/x-rtp, media=(string)video, clock-rate=(int)90000, encoding-name=(string)H264" ! rtph264depay ! h264parse ! omxh264dec ! videoconvert ! eglglessink sync=false

The client connect almost instantly to the rtp stream which is great. (compared to vlc, 5-10sec)
But the video stutters and glitches occasionally.
I'm also not sure which is the problem, the server or client.

[Defiant]

You should ask this in a separate, not dead thread.

this, and tkbd if you create a new thread please add more details, e.g. the medium you are using (wifi/ethernet)

Thanks

I read the links provided.....and did a fresh installation of gstreamer-1.0 on Raspbian Sketch thinking the problem was in the gstreamer's package.
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install gstreamer-1.0


while launching the code

Code: Select all

raspivid -f -b 10000000 -fps 30 -t 0 -o - | gst-launch-1.0 -v fdsrc ! h264parse! rtph264pay config-interval=1 pt=96 ! udpsink host=192.168.100.84 port=6000

It stills stops at the same point :

Pipeline is PREROLLED ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock

How did you solve that ?

[Idrive]

I've been using gtreamer for over a year. My Rpi Zero W is placed in a model train, and a bash file launches this:

Code: Select all

raspivid -t 0 -w 1920 -h 1080 -fps 20 -b 10000000 -o - | gst-launch-1.0 -e -vvvv fdsrc ! h264parse ! rtph264pay pt=96 config-interval=5 ! udpsink host=192.168.0.103 port=5000

On my Windows laptop I run this

Code: Select all

@echo off
F:\gstreamer\1.0\x86_64\bin\gst-launch-1.0 -e -v udpsrc port=5000 ! application/x-rtp, payload=96 ! rtpjitterbuffer ! rtph264depay ! avdec_h264 ! fpsdisplaysink sync=false text-overlay=false

And I used to get a smooth live stream via Wifi with a 0.2 sec delay.
Then, one day I turn everything on and all I get on my laptop is a green picture. I f I move the camera I can see something moving but very sloppy, terrible delay and lots of frozen pictures, all in green.

Between the last time the setup worked and the green picture nothing happened. No updates, nothing, everything's been in a box.

Tried changing the camera module, then changing the Rpi Zero W, then running apt-get update and upgrade, but I keep getting the green picture.

Any ideas?
I'm a newbie, the above commands are the product of hours of research on the net and trial & error. It was awesome till it worked, but now I really don't know what or where to tweak.

Thank you for any help you can provide,
Guido
