Hello again,

i found my Failure. I used a flv file which i recorded with the rtmpClient.
I don't know why,but at the beginning of the file a TextData Message is
written.

hexdump a.flv -C -n 100

00000064

sended by NetStream.send("statusMessage","Welcome...");
it seems the rtmpclient wrote this Message into the FLV,
and now the old streamID 0x02 is inserted into the new Stream...


I will patch the rtmpClient, that this type of messages arn't written
into the flv :) or is this behavior planned ?


Bye

Gabor

Hey,

Thanks a lot for identifying the problem. We will add your suggestion
to the SVN code soon.

Hi,
I am playing with siprtmp (6.0) and X-Lite (3.0 build 56125) as described i=
n the =93Testing=94 paragraph and I got the following error  :  AttributeErro=

Hi, 
I've updated my rtmplite versione to the latest 7.2 one, but webcam recorded 
clips won't playback correctly - buggy sound and slow video output.

After switching back to 7.0 the playback worked fine.

sometimes on SIP trace I can see 481 response. but everything works fine. What 
does it mean ? how to resolve it ?

thanks

On Ubuntu 10.10 I download rtmplite-6.0. I start the application...

python rtmp.py -d

Hello, and Congratulations for your nice little software SIP
videophone.

I would like to do some experiments with it and I need your help
for that as soon as possible.

1- I would like a plain version of the flash-to-Sip videophone page
without: (the text input form, without the buttons, without the
tool-tips, without the confirmation yellow bars in the bottom, just
a white background, no border, in other words, no visual elements
at all, but only a white plain square SWF object that I can fix the
size and the loggin infos in the html source myself). I ask you
because I don't want to break anything in the asc code if I edit it
myself for my experiments. send it in my email Please, I'm willing
to give you a donation for your help, and for future experiments
help also :-)

Best Regards

Marco

Hi Marco,

Not sure if we replied to you earlier or not. So am replying again.

Were you able to do this yourself?

You can edit View.mxml to remove various UI elements.
Then you can add code in VideoPhone.mxml::installJavaScriptAPI() to
add more API to control from JavaScript.

If you haven't done it already and if you find it difficult, I will
try to send you the new SWF. Let me know.

Hi Kundan,

I cannot do it, I was still waiting for your help, my experiment
need is that I will make it call a SIP number, that's it. so I
don't want
no graphics at all, and also I want it to be able to call just a SIP
number, without password or name remembering.

Can you do it for me please?

Best Regards

Marco

I am trying to interconnect SIP and flash using Asterisk as the SIP server, on 
my LAN. Here is one of the tests I have done, and its log. 
I am using Ekiga, it connects to Asterisk fine and can make calls from and to 
other SIP clients.
- First I connect the flash VideoPhone application to rtmplite
- Then I make Ekiga call the VideoPhone
- Then I pick up on the VideoPhone. It instantly connects and disconnects. 
Ekiga believes it is still connected, using speex. After 7 seconds, Ekiga hangs 
up automatically.
- At this time the VideoPhone starts ringing again (as if it is receiving a 
call), but picking up doesn't do anything of course, except reset the 
VideoPhone to standby mode, waiting for new calls.

Notice the same symptoms seem to happen when doing flash to flash calls using 
asterisk (but not p2psip, there it works fine), flash to phone and phone to 
flash (p2psip and asterisk), but asterisk with VideoPhone and Android native 
Gingerbread SIP client works fine, and so does Ekiga with the Android SIP 
client.

The log of the above described situation (Ekiga calls VideoPhone) is in the 
attached file (inlined), as well as the log of a flash to flash call over 
asterisk (both are using videophones) with the following scenario:

- First I register the first compouter (1001)
- Next I register the second computer (1004)
- Then 1001 calls 1004
- 1004 picks up and instantly connection is cut

Thanks for any help anyone may provide,
Yannack

Hi, I'm trying to use rtmplite for a project and whenever I make a call to the 
flash client, I get an error like the one below, I was wondering if you know 
how to fix it, although it looks like it is a problem with p2p-sip. Thanks!

SIP/2.0 488 Incompatible SDP

---

Hi Nico,

This might be a bug in the code that both sides are not using the same
SDP session. I see the following error: "SIP/2.0 488 Incompatible SDP"

Can you enable trace log using "-d" option or setting "_debug = True"
in appropriate .py files, so that it prints the full SIP messages.
Then send me the sender and receiver's INVITE and 200 OK message
traces. That will give good deal of information about why SDP m= lines
are incompatible.

Keep in touch and good luck!

---

Thank you very much for your reply, here's the whole trace, from when I start 
the server to when the call is terminated with the error. The flow is as 
follows:
* Start siprtmp
* Connect with flash
* Originate a call to the extension registered by flash through siprtmp
* When the called is answered in flash, siprtmp throughs an error and send an 
SDP saying incompatible destination

This happens only when calling flash. If I make the call from flash, there's no 
problem.

Hello,

 First thanks for this interesting project. Tried to make it work with
latest rtmplite and p2p-sip svn. The clients can connect to servers,
can view the initial camera video, can do the call, but just when the
call are
answered all cameras led became inactive and no video (only vertical rainbow
color bars) is shown. Logs are attached. I have the simple setup of
two boxes - first (10.1.0.100 is running siprtmp and sipd and
videophone.swf client named Dao, second (10.1.0.7) is running
videophone.swf client named acer. This is internal home network - no
firewalls and gateways - only hub connection. I see that contact field
in sipd logs are wrong for second client (it needs to be 10.1.0.7 but
seems like it is the same as for first client). Settings for
10.1.0.100 swf client are :

rtmp url - rtmp://localhost/sip
sip url - [email protected]
auth name - dao
auth pass - 1234 (do not care)
name - Dao

Settings for 10.1.0.7 swf client are :

rtmp url - rtmp://10.1.0.100/sip
sip url - [email protected]
auth name - acer
auth pass - 1234 (do not care)
name - Acer

 What can be the issue ? Sipd.py and siprtmp.py logs are attached. Can
supply any additional info.

Thanks in advance.

The FLV class has a reader task, which does not get terminated when the 
NetConnection or NetStream is closed in rtmpclient.py. Check whether it works 
on rtmp.py.

There are at the moment 166 open ports, although there is no activity
from our flash-client.
Is this expected behavior ? Is their something like a garbagecollector
involved ?
I must admit, that there is no python-specialist in our team for this project,
so we don't know is this is OK.
We would appreciate any help we can get from your site.

Best regards from germany

Hi Hakan,

Thanks for trying out siprtmp.

These port numbers are related to RTP/RTCP socket that are opened for
media stream.
I have a close() method in the voip.py::MediaSession and
rfc3550::RTPNetwork classes. The close
method of RTPNetwork gets called from MediaSession.close(), but I
guess the siprtmp is not calling the close() method.

I will try to look at the siprtmp.py's cleanup code to make sure that
it correctly closes the SIP and RTP sessions.

---

Thank you for your swift reply!

Thanks a lot for having a look at it.
Indeed, I believe that we suffer from unclean session aborts here.
The software we're using siprtmp against is freeswitch which uses
nokia's sofia sip implementation. If you feel that the aborted sessions
are owed to a bug in freeswitch or sofia sip, let me know and I'll hook
you up with the right person for the problem over at the freeswitch
project.

Hello! First, thanks for providing this. A lightweight RTMP server is
what I'm looking for. I'm trying to stream FLV videos. With the
supplied testclient, I can watch an FLV, but when I try to view it
using a commercial player like JW player or flowplayer, it just
displays animation that indicates it's loading but the video never
plays. For instance,
http://www.push-a-button.com/products/youglevista/rtmp.php is a site
that lets you play an rtmp stream you specify with flowplayer. About
the only reason I can think of at this point is that with my web host,
I'm using a non-standard port for my server, i.e. it's not 1935. If
you have any suggestions on how to make this work, I would greatly
appreciate it. If you don't have time to do support, I understand, but
if I can get this to work, I will definitely spread the word about
rtmplite at my web host support forum & also in JW player forum.

thanks,
John K

- siprtmp takes without calls about 2% of CPU and with one call about 10% with 
a nocona 2 x Xeon
This is a little weird since there is no audio/video encoding. 
is this the effect of RTMP to RTP loop ?

- how to define "Agent" name ? for now the b2bua proxy shows "unknown" as User 
agent (why not Kundan Sip ? :))

Measure the performance of rtmplite for simple (1) video recording, (2) 
playback streaming, (3) audio only, (4) siprtmp translation for audio call, (5) 
real-time two-party call.

I tried to configure siprtmp with
--int-ip as 127.0.0.1 and --ext-ip as a public ip 12.34.56.78
all SIP messages are going and received well, but no sound.
is it a NAT issue ? if yes, how should I set it ?

Thanks

Please help to build a rtmpclient_gevent.

Hi would it be possible to built a server side playlist so that I
could built a radio station ?

Currently siprtmp does not support re-INVITE handling (send '501 re-INVITE not 
implemented'). Require this feature to modify SDP (for change in remote media 
destination or hold/unhold).

I uplink using ffmpeg...
ffmpeg -i somevideo.mp4 -re -vcodec copy -acodec copy -f flv 
rtmp://localhost/live/livestream

In this case the video is H264/MP3 and known to work with other live rtmp 
streaming software e.g. Wowza and rtmpd.

If I try to connect to the stream using VLC using...
vlc -vvv rtmp://localhost/live/livestream

I get the following error report...

Hello.

Thank you for this project. I try to use it, but i have some question.
I try to record some video by call publish("some", "record"), server
create a file some.flv.
In next step i want to try play it, i write little player, which use
NetStream and Video components - it's works.
But i want to use FLVPlayback to watch recorded video, but it
components can't play video from server.
I try set a source property of component and try use play method, but
it not work.
In server debug mode i see, that server resive connection request and
answer on it, but next component command(s) not sent.
How to use FLVPlayback component?
Thank you. Aleksey.
P.S. Sorry for my english.

Hello,

First of all congrats for the project I really like it simplicity. I
am trying to build a multi-player game with Flex and Python - I am a
beginner with Python. I noticed that Python lists are nor sent
correctly to Flash - actually when I try to send a list I get corrupt
data on the Flash side. Currently I make a workaround by converting
lists to dictionaries before sending. Am I missing something?

Hi,

I tried rtmplite with openlaszlo, it works like a charm ! Only one thing. It's 
not nice to have to recreate FlashServer to override application methods.

So, I did a patch to allow user to override Application class and to pass 
"dict" to FlashServer constructor.

So you can do;
 class MyApp(Application):
    pass

 class MyOtherApp(Application):
    pass

And send it to constructor, for example:
 app = FlashServer(dict({'url1': MyApp, 'url2'; MyOtherApp}))

and h264) and 3G video phones. For the video, the GW need to use 2
different netstreams to get a smooth audio/video.

It will be great to get the DTMF, but I don't know how to add the in
the SIP/sdp and how to send them from the P2P-sip API.

This is a prototype to make our native RTMP channel in the Asterisk.

Fixed in p2p-sip's svn r26 (version 1.10)

Hi Kundan,

didn't have any news from you.
hope you're well.

after experiment with rfc3550
I noticed that with p2p and siprtmp
udp socket session still stays open undiefinetly
and the list of socket is growing after every call.
so despite of my bad knowledge in python
i got the trick below:

    def close(self):
        if _debug: print 'cleaning up sockets'
        if self.rtp: self.rtp.close(); self.rtp = None
        if self.rtcp: self.rtcp.close(); self.rtcp = None
        if self.app: self.app = None
        self = None
once the call hangup siprtmp clean completely the ocket
and avoid that all udp port raange to be reached.


Take care

Hi Franck,

I think I found the problem.
It was a terrible oversight on my part in rfc3550.py.
I have fixed it in svn r26 as shown in
http://code.google.com/p/p2p-sip/source/list

I have also attached rfc3550.py which you can use to replace yours in
p2p-sip/src/std/rfc3550.py

Thanks a lot for helping with this bug!

Reported by Valery <[email protected]> on Dec 9, 2009.

I got the latest source code and I found another issue, that seems is more 
critical.
In about 2-5 minutes of playing, the picture freezes. I dig a little and found 
out that the recv on publisher's socket stoped getting data.

To reproduce it faster I do minor changes to inclease bitrate.
- I changed width and height for video to 320x240
- added the code to 'private function publish'
        ns.publish(name, record ? 'record' : null);

        var camera:Camera = Camera.getCamera();
        camera.setMode(wVideo, hVideo, 30);
        camera.setQuality(0, 100);

        local.attachCamera(camera);
        ns.attachCamera(camera);

In about 30 seconds, it stops working.

Thanks,
Valery.

Hi,

Thank you for p2p-sip.

I am debugging memory leaks in siprtmp.py from rtmplite, and sipd.py from 
p2p-sip. siprtmp.py and sipd.py are based on p2p-sip. I know that in sip.py 
memory usage increases after every register request generated by asterisk 
1.4.22 on reregistration. This is because ServerTransaction and Proxy objects 
are not closed (removed from memory) after each successful register 
transaction. Therefore there is a buildup in the number of this object over 
time (40 MB over 4 days).

Can you advise what can be wrong and where to look for the solution in the code?

Best Regards / Pozdrawiam

Łukasz

---

I can try looking at the memory problem in rfc3261.py file.
There is a circular reference among transaction and Dialog/Proxy
object I feel. I think I had implemented a close() method in both the
classes. But may be the close() method is not getting invoked for
cleanup on the Proxy object.

Which tool are you using to detect the memory leak?

We can probably chat further on gtalk ([email protected]) and nail
this down....

---

I use pdb and objgraph from 
http://www.lshift.net/blog/2008/11/14/tracing-python-memory-leaks

I am new to python (I have experience in ruby, a little bit like python).

I think the problem occurs because of typo in rfc3261.py. Please see 
rfc3261.py.patch for more details. After this correction objects are correctly 
destroyed during registers/reregisters with asterisk.

I found some other leak occurring every time siprtmp.py registers/reregisters 
to sipd.py (increase in application memory consumption), but unfortunately I 
cant find any application objects in memory space after application termination.

siprtmp.py also have a number of more complicated memory leaks.

Hi Lukasz,

Thanks for the patch. That was a tricky typo and thanks for detecting.

We will add the memory leak detection as our things to do. I agree
that siprtmp.py is pretty primitive -- it was a student project and
haven't been regressed for robustness.

Hello,

I tried to use flash media encoder 2.5 with your rtmp server, but it
throws error "keyerror: objectencoding"... Is it possible to use fme
with your server or should I look for something else? Any help would
be apreciated.

Reported by Alon Gubkin <[email protected]> on Dec 1, 2010.

Are there any known issues with NetStream.bufferTime and rtmplite? For
some reason it doesn't work for me.

Thanks.

What steps will reproduce the problem?
1. play an FLV file where two frames have the same absolute timestamp
2. it will send a packet with absolute timestamp=0
3.

What is the expected output? What do you see instead?

The send routine only gets a relative timestamp passed to it. It should
only send an absolute timestamp for the first packet in a stream.


What version of the product are you using? On what operating system?
4.0 Linux

Please provide any additional information below.

The bug is caused by this "or header.time==0" condition at rtmp.py:316
>>>
            # now figure out the header data bytes
            if header.streamId != message.streamId or header.time == 0:
                header.streamId, header.type, header.size, header.time =
message.streamId, message.type, message.size, message.time
                control = Header.FULL
<<<

The attached patch seems to fix it for me, by insuring that header.time
will never be 0 after the first packet in the stream.

Transmitting video fail (client closes connection) when running server by 
siprtmp_gevent.py.
Problem in function FlashCliend.send(), there is no check for all data sent.
Solution: replace self.sock.send(data) to self.sock.sendall(data), or process 
sending in loop with counting sent bytes.

Hi great project!

Just wanted to know if in the rtmplite project if you have implemented
the Call Transfer function. I ask this question here because the
rtmplite is said to be using the p2p-sip stack from here.

Thanks in advance.

Hi,

I've downloaded and setup siprtmp on a centos server. The default python 
installation is 2.4 so i've done an alternate installation of 2.7. When i try 
to run the server using python2.7 siprtmp.py -d it shows 'Flash Server Starts - 
0.0.0.0:1935' and nothing happens after that. When i check on the ports using 
netstat there's no service running on port 1935. Is there something am doing 
wrong? How do i know when siprtmp is running?

Hi

Sorry for emailing you directly but I am not sure if the support is
working on Google Groups.

The audio seems to be dropping off when I record a file. The file
attached is an example.

Could the be something to do with the built in mic or some setting I
need to change

Great work on the apps and your write ups.

Hi Diarmuid,

Do you have some other audio tool which you can record and playback to
verify that your mic is working fine?

I suspect it is something else. Few questions if you can answer:

1. Is rtmplite running on same host as your browser in your test?

2. If (1) is no, then how is the bandwidth between your browser's host
and the host running rtmplite?

3. Do you have information about CPU usage (either window's task
manager or Mac's activity monitor can give this information) on the
machine that runs rtmplite? and that runs your browser? Is it showing
high (close to 100%) CPU usage?

4. Did you change any default parameter in VideoIO?

5. Which version of rtmplite are you using? or are you using the
latest SVN code?

6. What is your flash player version? Right click in VideoIO and then
left click on 'Adobe Flash Player...' to know the exact version
number.

---
Also I am attaching another VideoIO.swf if you can replace yours with this one.

The difference is that this one disables silence-suppression in
Microphone object of Flash Player, in case this was an issue.

Also in your experiment, if you can set the mic's volume to be max,
that will help.

---
Hi Kundan,

Thanks for the great reply.

Activity Monitor shows rtmplite running at 6 % when recording 1 stream.

Audio works fine with Photobooth.

I set the max volume in the flash recorder and that had the biggest
effect on the audio recorder. I think the echo check box may have had
some affect as well.

I also tested the Flash recorder (not rtmplite)  in Facebook that
works the same way with the volume control needing to be very high for
any audio to be recorded consistently. It could be something to do
with the 24" i-mac's build in mic. I also played around with the mac's
built in audio prefs and the default settings work well. Ambient noise
reduction makes a big difference but seems to have little impact on
the recorder

The recorder volume in flash seems to be quite crude as it need to be
very high before it picks up the sound. I wonder is this scriptable on
javascript.

Do you know of a RTMFP server to help with making peer to peer calls.
I see you use the Adobe stratus server , but maybe there is an open
source server out there??

I tried the recoder with two inpute streams and it worked fine. Any
idea how many could be recorded at once or is it based on server
capacity ?

Thanks for your help. I was telling a friend today how brilliant your
code and write-ups are. They are very impressive.

Cheers

---
Hey Diarmuid,

The recorder volume is also scriptable from Javascript using the
"gain" property as described in
http://myprojectguide.org/p/flash-videoio/10.html.

I don't know of any open source rtmfp server. There was some effort
that started out, but I haven't followed it recently.

One of the pending task I need to do is capacity/performance
measurement of rtmplite.

Hopefully I should be able to do that soon.

Thanks!

hi
I used siprtmp and I have a question about it
If I'm calling(using speex8) from flash to asterisk, on music on hold
extensions, sound quality is awful.(in trafshow seen that rtp flow is
unstable. From time to time the flow stops and then resumes again,
this leads to failures in the sound). But if i calling(using speex8)
from flash to freeswitch, on music on hold extensions, sound quality
are normal(steady stream of rtp). I'm confused.

There were some timestamp related bug fixes done in version 6.0 of
rtmplite/siprtmp. Can you please give it a try.

If you are already trying version 6.0 or later, could you please
enable RTP trace (set _debug=True in siprtmp.py, rtmplite.py and in
p2p-sip's rfc3550.py) and send the trace as reply. Basically I want to
see the RTP timestamp and actual RTMP time when packets are sent by
asterisk to Flash application.

Thanks.

I need a simple streaming system where only one client at a time can
stream (due to bandwitdh issues) and a director can choose which
client.

Look at this sketch: http://goo.gl/8vauk

At the end of this system there is a converter and a streaming service
(like ustream, icecast or similar) needed to broadcast the choosed
client.

What do you think? Is it feasible with rtmplite?

---

Hi Fabio,

Yes, this should be feasible with rtmplite.

Assuming that it is your web client, and the simplest option would to
be to send RPC commands from rtmplite to your Flash application to
enable/disable publish of the stream. The Flash client application
connects to the server rtmp://server/myapp/scope123. But the Flash
client will not publish until it receives "start_stream" command from
the server. The server built using rtmp.py and rtmpclient.py creates a
new FlashServer instance to listen to incoming Flash client
connections. The server already keeps track of list of connected
clients, and can decide which client it wants to start streaming from.
Then it sends a "stop_stream" command to any previously active client,
and "start_stream" command to new active client, using the "call"
method (look for how self.client.call is called in siprtmp.py to
indicate an event from server to client). The client application
invokes publish/close based on when it receives "start_stream" or
"stop_stream" commands. If you are using a third party Flash client
application, then you will need to handle this signaling out of band,
e.g., using separate signaling channel.

On the other side of the system, you will need to use the
NetConnection/NetStream objects of rtmpclient.py module to connect to
your existing streaming server, or have the existing streaming server
connect to rtmpclient. The rtmpclient module is capable of connecting
to existing RTMP server to publish or play a stream. You can use the
onPublishData callback (see rtmp.py) to receive the audio data from
the client, and NetStream's send to send it to the other streaming
service.

hope you're well...

Hello,

This looks like the server I am looking for. Red5 and others are
complex and since I am really a noob on flash very difficult to
understand.

I understand it supports live streaming to which you can connect. This
I might want to use in the future. However I am interested in using
the server as a .flv streaming server using the jw player.

However I tried you example application to stream some files but get
always the error: streamErrorHandler() asyncError Error #2095:
flash.net.NetStream was unable to invoke callback onMetaData.

How should I avoid this and can I use this server as a rtmp .flv
streaming server.

Some guidance would be very nice on how to configure this.

Thank you for your help

In summary, if the machine has multiple IP addresses, the siprtmp listens on 
one IP address for RTMP but another for SIP. Fix this, so that if IP address is 
supplied from command line, always use that.

I was able to register VideoIO with Freeswitch via siprtmp gateway but
there was no audio when I make a call. How do you suggest to
troubleshoot the issue?

Thank you,
Joshua

Hi,

Can you start siprtmp with -d option, and send me the program trace as
a text file. That can give some idea about what might be going wrong
in SIP/SDP negotiation. Problem could be in SDP codec negotiation or
in media port behind NAT/firewall.

Also, for next step, can you check if you can make call to your
freeswitch using X-lite (or some other SIP client) with only speex
enabled?
