[Announce] Smartcam Maemo 5 Port - Now with more Qt

Announcement

http://www.azkay.com/Screenshot-20110413-171103.png

What is this?
This is a client side port of the Smartcam Client software
It lets you use your N900 to stream video from either video0 or video1 to your windows PC, using it as a webcam.
Its compatible with most programs, skype, msn, etc.

IF YOU INSTALLED THE ORIGINAL C# VERSION, GO THROUGH THE INSTALL.SH AND REVERSE THE COMMANDS, THEN GO TO http://talk.maemo.org/showpost.php?p...3&postcount=19 AND REMOVE THE MONO RUNTIMES IF YOU ARENT USING THEM ANYMORE

What do I need?
- You need gstreamer installed

Code:

apt-get install gstreamer-tools

What do I do?
#0 Enable your wifi/usb networking!
#1 Download and install Smartcam for Windows
#2 Download and install Smartcam for Maemo 5

Code:

sudo gainroot

wget http://azkay.com/smartcam-m5_0_0_1_armel.deb

dpkg -i smartcam-m5_0_0_1_armel.deb

#3 Look through your applications, you should see Smartcam M5.
#4 Make sure Smartcam is running on Windows, make sure youve allowed it through firewalls.
#5 Open up Smartcam M5, put in the IP of your Windows PC and port for Smartcam; eg; 192.168.2.14:9361
#6 Hit <save> then hit <Start>

That should be it, if all went well you should be seeing live video on the Smartcam Windows side.

ToDo
Client
- Fix things, probably
- New logo/icon
- Back LED enable/disable

Server
- Code my own Smartcam server
- Windows & Linux
- Higher resolution stream
- Audio stream

End
Thanks me for for finally getting this done/released,
Thanks to danielz000 for all his help,
Thanks to deion for his work with Smartcam.
(hope you dont mind if I used the smartcam icon/logo in this, contact me if theres any problems, sourceforges contact is broken)

Be sure to put libmono*, with the asterisk.
If it still doesnt work,

Trying running it from terminal;
mono /etc/smartcam-m5/smartcam-m5.exe

Re: [Announce] Smartcam Maemo 5 Port

tried to install libmono* same thing....couldn`t find package.Try to run it from terminal I get " the assembly mscorlib.dll was not found or could not be loaded.It should have been installed in the /usr/lib/mono/2.0/mscorelib.dll directory

what`s libmono* ? Is there another way of installing it?

Re: [Announce] Smartcam Maemo 5 Port

Ill look into it when I wake up (in around 3 hours, blah), sorry.
5:34am, I really shouldve went to bed at 8pm.

Try the apt-get again with extras enabled and testing or also try adding:

Code:

deb http://go-mono.com/maemo diablo user

to /etc/apt/sources.list.d/hildon-application-manager.list

then apt-get update and apt-get install libmono*

apt-get remove libmono* one would imagine. Well I guess I wont be installing this until those libs are optified.

2011-03-24 20:14

Re: [Announce] Smartcam Maemo 5 Port

I would guess as root "apt-get purge libmono*"

The mono libs for 1 small streaming app is not really a bargain, is it.....?

Thanks nonetheless to the devs. Smartcam works on Symbian phones as well and so is rightly now on the n900 and maemo.

copied smartcam-m5.exe to /etc/smartcam-m5
etc etc

cp smartcam-m5.desktop /usr/share/applications/hildon
cp smartcam-m5.png /opt/usr/share/icons/hicolor/32x32/apps
cp smartcam-m5.conf /etc/smartcam-m5

Delete them, as root

Then as root:

Code:

apt-get purge mono-runtime

Ok, the mono-runtime included in the .gz is run-incompatible with the libmono* installs from the diablo repo.

Re: [Announce] Smartcam Maemo 5 Port

so, what does that mean?is that why the app is crashing for me?i dont wanna try and install it again,especially with the huge library that takes so much space on rootfs.i think ill wait for another optified version.

Re: [Announce] Smartcam Maemo 5 Port

Works - well done devs!!

Here are the files needed for a minimal mono install to run smartcam:

libglib2.0-cil_2.10.4-1_armel.deb
libgtk2.0-cil_2.10.4-1_armel.deb
libmono2.0-cil_2.4.3-1_all.deb
libmono-corlib2.0-cil_2.4.3-1_all.deb
ibmono-posix2.0-cil_2.4.3-1_all.deb
libmono-system2.0-cil_2.4.3-1_all.deb
mono-runtime_2.4.3-1_arvmel.deb

Best source of these is:

http://www.torosoft.com/mono-maemo5/.../binary-armel/

Please see thread post for my source of information: http://talk.maemo.org/showpost.php?p...2&postcount=21

Do not use the "http://go-mono.com/maemo/" repo as it is version mismatched with the run-time provided and the older runtime in the repo does not work (at least not for me).

I got errors updating the torosoft repo (ymmv) via fapman so I wget'ed the files and dkpg -i'ed 'em.

Re: [Announce] Smartcam Maemo 5 Port

Damn, I just got done apt-get purging' my libmono* and googling, found that thread, added that to apt and reinstalled them. Lololol.

Thanks, though. Maybe I can optify each deb then have them in the original tar.gz to make things easier.

Re: [Announce] Smartcam Maemo 5 Port

Your post is better than mine, I forgot that I had others installed already (gtk, etcetc), so my count was just corlib and posix, ha.

I was amazed when it actually worked at full fps (dont know about over wifi, havnt tried yet).
My original version was using TCP, it ran around 17fps, but was really really laggy, smooth/lag/smooth/lag.
Second version I moved over to UDP, fixed all the problems.
Then I looked at a GUI, then stopped because it was annoying me.
Then went back again, tried windows forms because it had been ported in through mono already, then I stopped because it was ugly and annoying me. Then I went back to GTK again to try and get it working, after 2 days of things making no sense, it finally worked.

There isnt any error checking, though. The only thing that error checks is when you hit "save", it checks if the ip:port is splittable into ip and port, so if theres no : itll error out. If the ip:port doesnt connect, itll error out, but ive yet to have it error while in use. Once it starts, it has yet to stop on me.

If you want to see how the GUI made no sense to align properly, open up the smartcam-m5.exe in windows, for some reason, I had to align it like that for it to come out right on the n900.

Re: [Announce] Smartcam Maemo 5 Port

It is good on wifi. I am impressed by the relatively low cpu usage at the get go.

I see that it is using gst-launch to feed to localhost - what are you doing to stream onto the network? Some mono library?

Regarding udp, does that create problems for trying to go over the WAN/internet as opposed to a LAN? If it does, perhaps there could be a udp/tcp option? I know tcp gives issues with resends --> latency etc whilst udp just streams on carelessly, but some routers kill udp traffic.

As for errors, if one closes the client smartcam then the n900 streamer crashes BUT the gst-launch process remains. Not good for battery :). Would be nice if it stayed up streaming so that you could go back but of course, the port is closed so.... but the n900 process should be killed of course.

Re: [Announce] Smartcam Maemo 5 Port

This is the original non-gui version,
basically, it listens on udp 127.0.0.1:5000, starts up gstreamer which streams jpegs to udp 127.0.0.1:5000, every jpeg it gets, it adds on the needed info for smartcam to use, then it tcpsends the frames to smartcam.

danielz000 was thinking we look at modifying tcpsink for gstreamer to add on the needed parts, that would take off the 8% of so usage the GUI has when its streaming:

Code:

using System;

using System.Net;

using System.Net.Sockets;

using System.Text;

using System.IO;

using System.Collections.Generic;

using System.Diagnostics;



public class UDPListener{

        private const int listenPort = 5000;

        

        public static int Main(){

        Console.Write("Smartcam IP [XXX.XXX.XXX.XXX] : ");

        string ip = Console.ReadLine();

        Console.Write("/dev/video[0] or /dev/video[1]: ");

        string source = Console.ReadLine();



                bool done = false;

                UdpClient listener = new UdpClient(listenPort);

                IPEndPoint groupEP = new IPEndPoint(IPAddress.Any, listenPort);

                byte[] receive_byte_array;

        Queue<byte> _buffer = new Queue<byte>();

        byte[] message = new byte[2];

        

        TcpClient _tc = new TcpClient(ip, 9361);

        NetworkStream _ns = _tc.GetStream();



        Process.Start(String.Format("gst-launch-0.10 v4l2camsrc device=/dev/video{0} driver-name=omap3cam ! ffmpegcolorspace ! video/x-raw-yuv,width=320,height=240 ! jpegenc ! udpsink host=127.0.0.1 port=5000", source));



                try{

                        while(!done){

                                receive_byte_array = listener.Receive(ref groupEP);

                if (receive_byte_array.Length != 0){

                    byte[] _fileData = receive_byte_array;

                    byte[] _tmpSize = new byte[4];

                    _tmpSize = BitConverter.GetBytes(_fileData.Length);



                    _buffer.Enqueue(1);

                    _buffer.Enqueue(_tmpSize[2]);

                    _buffer.Enqueue(_tmpSize[1]);

                    _buffer.Enqueue(_tmpSize[0]);



                    foreach(byte _b in _fileData){

                        _buffer.Enqueue(_b);

                    }



                    byte[] _packet = _buffer.ToArray();

                    _ns.Write(_packet, 0, _packet.Length);



                    _buffer = new Queue<byte>();

                }

                        }

                }catch(Exception e){

                        Console.WriteLine(e.ToString());

                }

                

                listener.Close();

                return 0;

        }

}

Ill have to look at hooking the close event, to have it kill gststreamer, if I can.

I couldve probably coded this in python, save installing all the libs and such, but Ive been trying to force myself to use c# more lately and mono being available on n900 made me want to use it.

Ill try streaming it over the internet, the quality slider should help, maybe later an optional framerate limiter.

EDIT::
I portforwarded then connected through my public ip:port over wifi, a little delay but worked fine (was using front cam, around half quality on the slider). Then I tried over 3g, I dont get good 3g reception here, but I dont think itll work too well anyway, maybe with a frame limiter (and if youve got lots of bandwidth to waste), it was really delayed, hitting Stop didnt close gstreamer, I think it just piles up the frames and nothing really ends up getting through after a little while, had to turn off 3g/kill smartcam-m5

If anyone wants to test some "global" streaming, from one n900 to anothers computer, let me know.

If it crashes over /dev/video1 and gstreamer is not running- but theres still the red light, the only fix ive found is to run:

Code:

gst-launch v4l2camsrc device=/dev/video1 num-buffers=1 ! fakesink

to let it reactivate/deactivate, wish I knew why it does it.

maemo-sharp is not necessary for this to function.

Now that out of the way - I have to say I am pretty damn impressed with the speed of this over wifi - even at max quality. Skype recognized it immediately and I was able to use it for other PC based apps requiring video.

Not bad - if a little large.

Have to agree with you - you do need to kill that gst-launcher process when the app closes however. Otherwise you have a 25% cpu eater just sitting there.

2011-03-25 04:45

Re: [Announce] Smartcam Maemo 5 Port

If you hit Stop before closing it, it *should* work.
I was having problems thinking of the best way to close it.

Currently when you hit stop, it sends a # packet which gets intercepted and runs gst.CloseMainWindow(), but it doesnt seem to work every time. gst.Close() doesnt seem to close it at all, might have to Process.Start("kill " + gst.Id).

Dont know how "proper" it is to do that, though.
Also, a problem with smartcam, it doesnt seem to work on some flash based sites that use the webcam; eg; tinychat.com, it shows smartcam as disconnected or something, if you choose it anyway flash crashes.

But yeah, other than that its worked in everything else.

Re: [Announce] Smartcam Maemo 5 Port

@azkay: if you don't mind, what is the advantage in using driver=omap.. with gst-launch? I could not see any reduction in cpu use, in fact if anything it increases it, as "omap3camd" kicks in, offsetting any reduction in gst-launch's cpu use. Does hw accel improve framerate?

I was having problems thinking of the best way to close it.

In my testing stop works just fine, the issue arises when the receiver disconnects, smartcam goes away without tidying up. Ideally, the gui should not disappear if tcp crashes, but revert to the gui with the "stop" button changed to "start". I assume this is what you meant by there being no error checking?

Dont know how to use hardware acceleration, there was a hardware accelerated jpeg encoder for gstreamer in the past, but I cant find it anymore. I dont think it would improve framerates any higher, I think around 30 is the hardware limitation of the camera, I could be wrong.
Hardware acceleration would be for less cpu usage I would think.

on windows, open up command prompt and type ipconfig, paste the output.
what ip/port are you connecting with (from n900), in smartcam on the PC go file > settings and check the port is the same.

Make sure youve got your wifi enabled, or if your doing it over usb, make sure thats all working right. brbrb, going to pie shop, be back in 15 minutes.

Ive enable 9361 Port to my router so in smart cam i go 10.0.0.1:9361

Im connected to Wifi on both PC and N900 on windows smartcam i see it connected for like 1 second no video not enough time but it does say connected and then the app closes down on the n900..

Re: [Announce] Smartcam Maemo 5 Port

Do you have gstreamer installed? The local part seems to have a problem with how your network is setup, dont know why.

If its giving a file not found over 3g, that would be at the line where it tries to run gst-launch.

Re: [Announce] Smartcam Maemo 5 Port

I thought gstreamer was installed by default on the n900;
try

Code:
