RTMP streaming in web page

Hi everyone,

This is my first post as a gstreamer user, so feel free to correct me :)

I am currently trying to develop a web interface for an ARM platform, in which is embedded an optical captor.

I am able to stream video for the host to a desktop computer without any problem. Here is an example that works :
gst-launch udpsrc port=1234 ! gdpdepay ! ffdec_mpeg4 ! sdlvideosink sync=false on the PC side, and then
gst-launch v4l2src ! video/x-raw-yuv,width=640,height=480,format='(fourcc)'YV12 ! mfw_mpeg4encoder ! gdppay ! udpsink host=192.168.0.10 port=1234 on the platform.

The idea is now to use RTMP so that the stream can be outputed in a web page using the vlc plugin.
For that, the command line on the camera is :
gst-launch -v v4l2src ! video/x-raw-yuv,width=640,height=480,format='(fourcc)'YV12 ! mfw_mpeg4encoder ! rtpmp4vpay send-config=true ! udpsink host=192.168.0.10 port=1234
(where mfw_mpeg4encoder is an embedded hardware encoder)

I use a configuration file stream.sdp :
v=0
m=video 1234 RTP/AVP 96
c=IN IP4 192.168.0.10
a=rtpmap:96 MP4V-ES/90000
a=fmtp:96 profile-level-id=245,config=000001b0f5000001b5090000010000000120008440
a=cliprect:0,0,480,640
a=framesize:96 640-480

And I feed Vlc with this file to get the streaming.

It works fine, as long as I set Vlc first, and then launch the gstreamer command line.
If the streaming is already started, Vlc detects the stream but is unable to display any data.

Same case if the stream is outputed, then stopped and started again.

Which means that each time, I need to set Vlc up first, and then start the streaming. And to do it again, I have to fully close vlc and start over completely.

The same phenomenon appears when using gstreamer itself instead of vlc to catch the stream :
gst-launch playbin uri=file:///home/jlengrand/Desktop/Dropbox/Taf/stream.sdp

could someone please help me on this?
I would really like to be able to stop and start more than one streaming whitout closing my client. And most of all, I would appreciate is the client could receive a streaming that has already started !

Any suggestions are welcome ! !

Thanks and Greetings

Julien

gdppay doesn't really work over UDP, but anyway..

Try the config-interval=2 property on rtpmp4vpay, it sends the config
string every 2 seconds.

Re: RTMP streaming in web page

In reply to this post by julien.lengrand-lambert

So, here are some news.
I had an older version of gstreamer and gst-plugins. I cross-compiled the newer versions, so that the config-interval option can be available.

The command line is then :
$ gst-launch -v v4l2src ! video/x-raw-yuv,width=640,height=480,format='(fourcc)'YV12 ! mfw_mpeg4encoder ! rtpmp4vpay send-config=true config-interval=2 ! udpsink host=192.168.0.10 port=1234

But it does absolutely not change my problem, neither in vlc nor in gstreamer . . .

Does someone know where I should search to solve this issue?

I did not succeed streaming video flux in the firefox vlc plugin with something else than this sdp file :s

Thanks by advance for your support.

Julien

I see you're using a live source, so there's no grant that starting
twice the stream you'll get the same config (and it's unlikely imo).
Maybe you could try removing the config, as you're now already sending
it in-band.

it would greatly help if you could post somewhere the debug log you
get after setting GST_DEBUG=3 (or higher) on the sending and (more
interesting) receiving side, as you're able to reproduce the issue
with GStreamer on both ends. If more than 10 lines, please post to
pastebin or attach as txt file.

Hi,

Once again, thanks for your help.

Perhaps should I have sent the logs in my first message.
I removed the config line, as you said, and it still works the same way than before.

Not worse, not better. So I guess i don't need it anymore :)

You will find enclosed the 3 logs I performed.
2 using gstreamer as the client and the server and the last one with vlc as client.

Both client logs mention a "header damaged" error, so perhaps is it the source of the problem.
However, I am unable to really find the reason for that error :s

I hope you can give me some lights on this issue !

Thanks again

Julien

Sorry again, the files were scrubbed :s .

Here are the links of the three logs :

http://dl.dropbox.com/u/11909603/client_hope => client with gstreamer
http://dl.dropbox.com/u/11909603/cvlc_log => client with cvlc

I hope everything will be fine this time

Re: RTMP streaming in web page

Hi,

sorry for the late reply. I grasped only now that you're using a
custom (hardware-specific) encoder. It should not matter as long as it
sends the parameters set to the payloader within the "codec-data"
field (you can check through the caps negotiated bw encoder and
payloader), so check whether it's a configurable option if not
enabled.

Said so, the behaviour of both the clients (GStreamer and VLC) is
expected, because their decoders never get an essential piece of
information that is the configuration data. As it appears such an
information is never re-sent from the payloader (even with
send-config=true config-interval=2) the most plausible cause is the
one I wrote in the paragraph above.

As a note, the following pipelines work correctly on my old eeepc:

gst-launch v4l2src ! \
video/x-raw-yuv,width=640,height=480,format='(fourcc)'YV12 ! \
ffmpegcolorspace ! ffenc_mpeg4 ! rtpmp4vpay \
send-config=true config-interval=2 ! udpsink host=127.0.0.1 port=1234

gst-launch udpsrc port=1234 ! \
"application/x-rtp,media=(string)video,clock-rate=(int)90000,encoding-name=(string)MP4V-ES,
payload=96" ! \
rtpmp4vdepay ! ffdec_mpeg4 ! xvimagesink

in case your encoder does not have an option to encapsulate
parameter-sets into the src caps, it's still possible to use a parser,
that is the sending pipe should be modified as follows (note the stub
for the encoder name):

gst-launch v4l2src ! \
video/x-raw-yuv,width=640,height=480,format='(fourcc)'YV12 ! \
ffmpegcolorspace ! your_encoder ! mpeg4videoparse ! rtpmp4vpay \
send-config=true config-interval=2 ! udpsink host=127.0.0.1 port=1234

I hope this will help.

PS next time you copy/paste debug output, please remember to disable
output color with something like:

export GST_DEBUG_NO_COLOR=1

Regards

Re: RTMP streaming in web page

In reply to this post by julien.lengrand-lambert

Hi,

Thanks a lot for your message.

I am trying to test your two command lines right now, but struggling a bit.

The last Ubuntu packaged version for gst-base and plugins is 0.10.28, which does not include he config-interval option.
I must then compile from the source, but I get errors with the configure in plugins-good which is searching for its dependencies in the /usr/bin folder.

Is there a way to inform the configure file that my binaries are in a custom folder? I searched in the source, but failed for now :S.

Anyway, the information you gave about the hardware encoder are interesting. I did not think that the problem could come from there.
I will try to find the sources, so that a solution can be found.

Thanks again,
I inform you as soon as I get more information.

Julien

I fell in your same issues in the past. You can try and use jhbuild
(you'll need to go through a few docs before succeeding):

http://library.gnome.org/devel/jhbuild/stable/jhbuild-and-gnome.html.en

----

Alternatively, I wrote my own set of scripts. You can take inspiration
from them:

http://gitorious.org/mkgst

please note they're nothing official (personal use only ;) ), so your
degree of success may vary depending on upstream GStreamer
developments / your building environment. The last time I've used them
(the last week) they worked pretty well on a freshly installed Ubuntu.

If you're lucky the only thing you'll have to do in order to build
GStreamer from git is:

cd to the dir containing the mkgst folder
run bash ./mkgst/mkgst.sh

if you're so lucky that build succeeds, in order to set up your shell
to use the newly built environment you'll have to run:

. ./mkgst/setenv.sh

P.S. maybe you'll have to remove some of the -dev packages from your Ubuntu box.

good luck!
