How to build a Video Broadcaster, which can handle more than 20,000 viewers

- by Gaurav Srivastava

I want to broadcast Video from a web cam, over internet. The problem is, the Video will be viewed live by more than 20,000 people (expected). I have a very little experience with Red5 Broadcasting. I did some broadcasting using Red5 and Flash. It works fine for 1 or 2 viewers i.e. it is great for personal chatting/ video conferencing applications. But, when the number of viewers increases, the delay in Broadcasting also increases. I am experiencing a Delay addition of about 0.5 Seconds for every new user who joins the broadcast. Can any one suggest me some, better technologies on which I can work out this Live Broadcasting. I don't want to use http://www.ustream.com; I want to create one of my own, such tool. But thats always the last solution.

.htaccess URL is being cut at a space (I'm using Codeigniter)

- by Ice

I've used the following code to map https://live.example.com on to http://example.com/api Options +FollowSymLinks RewriteEngine On RewriteCond %{HTTPS} =on RewriteCond %{HTTP_HOST} ^live\.example\.com [NC] RewriteRule (.+)$ "http://example.com/api/$1" [L,P] The following url: https://live.example.com/userlinks/xml/John%20James/MvPjeUTo15/ Is suppose to map onto: http://example.com/api/userlinks/xml/John%20James/MvPjeUTo15/ Instead it maps it to: http://example.com/api/userlinks/xml/John So it seems to cut it at the space. I am using the Codeigniter framework but I am not sure if the problem lies there. Also using %20 or just a space in the url bar produces no different results. Anyone any idea and/or solution why this happens? Thank you very much, Ice

I have configured virtual machine on ubuntu with the help of below article, https://help.ubuntu.com/9.04/serverguide/C/libvirt.html I managed to finish all the part except the major portion getting virtual host to talk to real network, Which I guess should be done only via bridge interface. Via virtual machine manager I try to choose any interface it gives me interface not bridged When I try to bridge the interceface eth0 as below auto br0 iface br0 inet static address 192.168.0.223 network 192.168.0.0 netmask 255.255.255.0 broadcast 192.168.0.255 gateway 192.168.0.1 bridge_ports eth0 bridge_fd 9 bridge_hello 2 bridge_maxage 12 bridge_stp off I cannot communicate with this interface to network, host server looses all the communication to network.

Copy 2 databases without detach in SQL 2005

- by molgan

Hello I have a server with live databases, and I have a test-server where I sometimes restore databases from the live one, to get fresh data. But this way I have to set up all the users again, I have about 4 different users with different permissions that need set again. Is there some way to do this a better way without using detach and attach, since I cant take the databases offline on the live-server? Prefered some thing I could run that "re-fills" the tables with fresh data. No need to redo stored procedures and rights. /M

Set Focus After Last Character in Text Box

- by Josh

I have 3 text boxes for a phone number. As the user types, it automatically moves from one textbox to the next. When the user presses backspace, I can move focus to the previous text box. The problem is that in IE, focus is set to the beginning of the text box. Here's my code, which works fine in chrome. $('#AreaCode').live('keyup', function (event) { if ($(this).val().length == $(this).attr("maxlength")) $('#Prefix').focus(); }); $('#Prefix').live('keyup', function (event) { if (event.keyCode == 8 && $(this).val().length == 0) $('#AreaCode').focus(); if ($(this).val().length == $(this).attr("maxlength")) $('#Number').focus(); }); $('#Number').live('keyup', function (event) { if (event.keyCode == 8 && $(this).val().length == 0) $('#Prefix').focus(); }); How do I make the focus set at the end of the contents when going backwards?

Mirror a website with httrack while executing javascript

- by Martin

I want do save a mirror of www.youtube.com/tv. I obviously do not want to save the videos. I want the code running the website in a local copy, everything else can stay remote. The code I want is mainly contained in 2 files: live.js and app-prod.js. I tried using httrack. I have issue parsing the javascript to load anything past the first file: live.js. The %P parameter does not help. httrack www.youtube.com/tv +* -r6 --mirror -%P -j It doesn't go further than live.js because some javascript needs to be executed to load the next file. I know I can do this manually with any browser. I want to automate the process. Is httrack able to do this by itself? If yes, how?

Get value from ajax-loaded form before submitting

- by ldvldv

Hi, I have an app that loads an ajax form when a button is clicked. I then want to check a value in that ajax loaded form called "comment_content" so that I don't send an ajax request if the comment_content is empty. I can capture the form submission using the live method, however, I can't capture the form element because it needs an element. I was looking at livequery but was wondering if there is a more efficient way by using live or if that I shouldn't even bother? Your help is very much appreciated. $("#comment_submit").live('click', function(){ var comment = $("#comment_content").html(); if(comment == ""){ $("#notice").html("").stop(true, true); $("#notice").append("<p>Are you going to write something in that comment?</p>"); $('#notice').slideDown().delay(2000).slideUp(); return false; } return true; });

XmlSerializer.Deserialize blocks over NetworkStream

- by Luca

I'm trying to sends XML serializable objects over a network stream. I've already used this on an UDP broadcast server, where it receive UDP messages from the local network. Here a snippet of the server side: while (mServiceStopFlag == false) { if (mSocket.Available > 0) { IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Any, DiscoveryPort); byte[] bData; // Receive discovery message bData = mSocket.Receive(ref ipEndPoint); // Handle discovery message HandleDiscoveryMessage(ipEndPoint.Address, bData); ... Instead this is the client side: IPEndPoint ipEndPoint = new IPEndPoint(IPAddress.Broadcast, DiscoveryPort); MemoryStream mStream = new MemoryStream(); byte[] bData; // Create broadcast UDP server mSocket = new UdpClient(); mSocket.EnableBroadcast = true; // Create datagram data foreach (NetService s in ctx.Services) XmlHelper.SerializeClass<NetService>(mStream, s); bData = mStream.GetBuffer(); // Notify the services while (mServiceStopFlag == false) { mSocket.Send(bData, (int)mStream.Length, ipEndPoint); Thread.Sleep(DefaultServiceLatency); } It works very fine. But now i'me trying to get the same result, but on a TcpClient socket, but the using directly an XMLSerializer instance: On server side: TcpClient sSocket = k.Key; ServiceContext sContext = k.Value; Message msg = new Message(); while (sSocket.Connected == true) { if (sSocket.Available > 0) { StreamReader tr = new StreamReader(sSocket.GetStream()); msg = (Message)mXmlSerialize.Deserialize(tr); // Handle message msg = sContext.Handler(msg); // Reply with another message if (msg != null) mXmlSerialize.Serialize(sSocket.GetStream(), msg); } else Thread.Sleep(40); } And on client side: NetworkStream mSocketStream; Message rMessage; // Network stream mSocketStream = mSocket.GetStream(); // Send the message mXmlSerialize.Serialize(mSocketStream, msg); // Receive the answer rMessage = (Message)mXmlSerialize.Deserialize(mSocketStream); return (rMessage); The data is sent (Available property is greater then 0), but the method XmlSerialize.Deserialize (which should deserialize the Message class) blocks. What am I missing?

Hi, I am getting the error Fatal error: Cannot redeclare config() (previously declared in.../basics.php:58, in live server. It works fine in my local server but when i uploaded the site to live server, i got the fatal error. I checked if the config() was declared multiple times but it's only declared once in basics.php file. The naming conventions are also followed, as it is working fine in local server. It only displays such error in live site. Please suggest solution for this. Help on this will be much appreciated.

How to handle dependency files in a cross-platform manner?

- by Brian Knoblauch

I'm working on updating an old app. It has some dependency files that live in the same directory as the app. Obviously this broke when Windows Vista came out (since it violates the API and Vista/7 now enforce that (XP didn't)). Ideally, I'd like to avoid hardcoding anything into the app for just Windows. I can live with that if I have to though. I've already been down that path with pulling the APPDATA and LOCALAPPDATA environment variables, but that doesn't help any since they just give you the current user area... I need these to live somewhere accessible for all users, and I'd like to obey the Windows API expectations that they go into the all user appdata area. Suggestions?

C#/XNA Giant Memory Leak

- by user1440926

this is my first post here. I'm making a game in Visual Studio 2010 using XNA, and i've hit a giant memory leak. My game starts out using 17k ram and then after ten minutes it's upto 65k. I ran some memory profilers, and they all say that new instances of the String object are being created, but they aren't live. The amount of live instances of String hasn't changed at all. It's also creating instances of Char[] (which i'd expect from it), Object[], and StringBuilder. My game is pretty new but there's too much code to post here. I have no idea how to get rid of instances that aren't live, please help!

SVN files edited thru FTP, How do I fix the edited files so they work thru SVN again?

- by Bobby

Basically, a 3rd party analyst we brought on to make some improvements to our site decided to edit files directly on the live server threw FTP. Any time we make changes to those pages threw SVN we have PHP parse errors. Things should be edited threw the SVN and committed. We have our working copies setup so we can edit them how ever we want while having them running under apache for testing. We commit all of our changes to a local repository, then commit from there to the live server. The code on the live server that causes the parse error has " .mine" and " .rxxxx", and my question is, how can I revert those files back to before they were edited thru FTP so I can update them threw SVN again?

Getting service unavailable message when sending messages to google xmpp using wokkel

- by Code freak

Hi, I made a wokkel (twisted python) bot to send and receive messages from the google xmpp service. Everything (auth, presence) etc works fine. One of the rquirements of our prject is that we need to send broadcast messages to everyone in the list. Normal messages and replies work fin, but when i snd a broadcast message, i get this service unavailable error 503 message. There are about 1000 user in my contact list. Is this some bug in the code or is it google policy to prevent rapid messaging. Also, how do other google bots cater to a large contact base ? does google provide a commercial solution for such applications ? Thanks

Is it possible to creating a Service without starting it?

- by ThaMe90

Hello all, I wonder, is it possible to create a Service, set some data, and then start it? I haven't come across a thread specific to this problem, so I would like to know if it is possible (if it is known of course). My problem is that I have a Service which listens to a DatagramSocket, but the socket in question needs to be set after creation, but before the start of the Service. The setting of the socket happens through the use of a Broadcast (I broadcast 2 Strings which hold the IP-Address & Port and the BroadcastReceiver then constructs a socket for me). When the Service is started, a Thread will start to run and listen to the supposedly created socket. This, sadly, doesn't happen. The socket will remain null and I can't set it when the Thread is running (This is another issue I hope to tackle in the future, if anybody got any ideas about this, please notify me). So, is what I want possible, or should I come up with another construct for achieving this goal?

how to make bridge networking with KVM work in Fedora19

- by netllama

I'm attempting to get several virtual machines setup on a Fedora-19 host system, with the traditional bridge network devices (br0, br1, etc). I've done this many times before with older versions of Fedora (16, 14, etc), and it just works. However, for reasons that I cannot figure out, the bridge doesn't seem to be working in Fedora19. While I can successfully connect to the outside world (local network + internet) from inside a VM, nothing can communicate with the VM from outside (local network). I'm referring to something as trivial as pinging. From inside the VM, I can ping anything successfully (0% packet loss). However, from outside the VM (on the host, or any other system on the same network), I see 100% packet loss when pinging the IP address of the VM. My first question is simply, does anyone else have this working successfully in F19? And if so, what steps did you need to follow? I'm not using NetworkManager at all, its all the network service. There are no firewalls involved anywhere (iptables & firewall services are currently disabled). Here's the current host configuration: # brctl show bridge name bridge id STP enabled interfaces br0 8000.38eaa792efe5 no em2 vnet1 br1 8000.38eaa792efe6 no em3 br2 8000.38eaa792efe7 no em4 vnet0 virbr0 8000.525400db3ebf yes virbr0-nic # more /etc/sysconfig/network-scripts/ifcfg-em2 TYPE=Ethernet BRIDGE="br0" NAME=em2 DEVICE="em2" UUID=aeaa839e-c89c-4d6e-9daa-79b6a1b919bd ONBOOT=yes HWADDR=38:EA:A7:92:EF:E5 NM_CONTROLLED="no" # more /etc/sysconfig/network-scripts/ifcfg-br0 TYPE=Bridge NM_CONTROLLED="no" BOOTPROTO=dhcp NAME=br0 DEVICE="br0" ONBOOT=yes # ifconfig em2 ;ifconfig br0 em2: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet6 fe80::3aea:a7ff:fe92:efe5 prefixlen 64 scopeid 0x20<link> ether 38:ea:a7:92:ef:e5 txqueuelen 1000 (Ethernet) RX packets 100093 bytes 52354831 (49.9 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 25321 bytes 15791341 (15.0 MiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device memory 0xf7d00000-f7e00000 br0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 inet 10.31.99.226 netmask 255.255.252.0 broadcast 10.31.99.255 inet6 fe80::3aea:a7ff:fe92:efe5 prefixlen 64 scopeid 0x20<link> ether 38:ea:a7:92:ef:e5 txqueuelen 0 (Ethernet) RX packets 19619 bytes 1963328 (1.8 MiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 11 bytes 1074 (1.0 KiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 Relevant section from /etc/libvirt/qemu/foo.xml (one of the VMs with this problem): <interface type='bridge'> <mac address='52:54:00:26:22:9d'/> <source bridge='br0'/> <model type='virtio'/> <address type='pci' domain='0x0000' bus='0x00' slot='0x03' function='0x0'/> </interface> # ps -ef | grep qemu qemu 1491 1 82 13:25 ? 00:42:09 /usr/bin/qemu-system-x86_64 -machine accel=kvm -name cuda-linux64-build5 -S -machine pc-0.13,accel=kvm,usb=off -cpu SandyBridge,+pdpe1gb,+osxsave,+dca,+pcid,+pdcm,+xtpr,+tm2,+est,+smx,+vmx,+ds_cpl,+monitor,+dtes64,+pbe,+tm,+ht,+ss,+acpi,+ds,+vme -m 16384 -smp 6,sockets=6,cores=1,threads=1 -uuid 6e930234-bdfd-044d-2787-22d4bbbe30b1 -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/cuda-linux64-build5.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=localtime -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/var/lib/libvirt/images/cuda-linux64-build5.img,if=none,id=drive-virtio-disk0,format=raw,cache=writeback -device virtio-blk-pci,scsi=off,bus=pci.0,addr=0x4,drive=drive-virtio-disk0,id=virtio-disk0,bootindex=1 -netdev tap,fd=25,id=hostnet0,vhost=on,vhostfd=26 -device virtio-net-pci,netdev=hostnet0,id=net0,mac=52:54:00:26:22:9d,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -vnc 127.0.0.1:1 -vga cirrus -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5 I can provide additional information, if requested. thanks!

VirtualBox - Public Static IP for a Debian Guest on a Dedicated Server

- by user86296

Goal: I want to run a Debian-squeeze-Guest in VirtualBox and it's own public static ip. I found tons of threads about this topic, but all in all I'm now trying for 10 hours (reading the manual, the forums, trying to learn about networking concepts & commands) to give a Guest his own public static ip (so that the Guest is similar to a vServer you can order from a hosting company), but wasn't able to. Since I'm a big noob as far as networking stuff is concerned, I'm probably doing something wrong.(please bear with me :-) ) Situation: VirtualBox 4.0.10 (headless no gui) is running on a dedicated Debian-Server, the Guest OS is Debian as well. The server has a static ip and I ordered an additional ip for a VM. Problem description: Upto now I was able to use NAT to access the VM from the outside and to setup an internal network between several Guests and all of this worked very well. When setting NIC 1 to bridged and configuring a public static ip on the guest, the guest was unpingable. (neither from outside, nor from the host) I could connect to the guest via the internal network, from another vm, though. ( VBoxManage controlvm VMGuest nic1 bridged eth0 ) ( configuration attempt of static-ip on the guest '/etc/network/interfaces' is below) Please let me know what I'm doing wrong, or what I can try to get it to work, or if you need more info. I think I've read that with a current VirtualBox-version for bridged networking no special host-configuration is necessary, is that accurate, or might that be the problem? Additional Info Info I got from the hosting company about the additional IP Please note that you can use the IP address only for this server.

unable to sniff traffic despite network interface being in monitor or promiscuous mode

I'm trying to sniff out my network's wireless traffic but am having issues. I'm able to put the card in monitor mode, but am unable to see any traffic except broadcasts, multicasts and probe/beacon frames. I have two network interfaces on this laptop. One is connected normally to 'linksys' and the other is in monitor mode. The interface in monitor mode is on the right channel. I'm not associated with the access point because, as I understand, I don't need to if using monitor mode (vs promiscuous). When I try to ping the router ip, I'm not seeing that traffic show up in wireshark. Here's my ifconfig settings: daniel@seasonBlack:~$ ifconfig eth0 Link encap:Ethernet HWaddr 00:1f:29:9e:b2:89 UP BROADCAST MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Interrupt:16 lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:112 errors:0 dropped:0 overruns:0 frame:0 TX packets:112 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:8518 (8.5 KB) TX bytes:8518 (8.5 KB) wlan0 Link encap:Ethernet HWaddr 00:21:00:34:f7:f4 inet addr:192.168.1.116 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::221:ff:fe34:f7f4/64 Scope:Link UP BROADCAST RUNNING MTU:1500 Metric:1 RX packets:9758 errors:0 dropped:0 overruns:0 frame:0 TX packets:4869 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:3291516 (3.2 MB) TX bytes:677386 (677.3 KB) wlan1 Link encap:UNSPEC HWaddr 00-02-72-7B-92-53-33-34-00-00-00-00-00-00-00-00 UP BROADCAST NOTRAILERS PROMISC ALLMULTI MTU:1500 Metric:1 RX packets:112754 errors:0 dropped:0 overruns:0 frame:0 TX packets:101 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:18569124 (18.5 MB) TX bytes:12874 (12.8 KB) wmaster0 Link encap:UNSPEC HWaddr 00-21-00-34-F7-F4-00-00-00-00-00-00-00-00-00-00 UP RUNNING MTU:0 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) wmaster1 Link encap:UNSPEC HWaddr 00-02-72-7B-92-53-00-00-00-00-00-00-00-00-00-00 UP RUNNING MTU:0 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) Here's my iwconfig settings: daniel@seasonBlack:~$ iwconfig lo no wireless extensions. eth0 no wireless extensions. wmaster0 no wireless extensions. wlan0 IEEE 802.11bg ESSID:"linksys" Mode:Managed Frequency:2.437 GHz Access Point: 00:18:F8:D6:17:34 Bit Rate=54 Mb/s Tx-Power=27 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality=68/70 Signal level=-42 dBm Noise level=-69 dBm Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 wmaster1 no wireless extensions. wlan1 IEEE 802.11bg Mode:Monitor Frequency:2.437 GHz Tx-Power=27 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off Link Quality:0 Signal level:0 Noise level:0 Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0 Tx excessive retries:0 Invalid misc:0 Missed beacon:0 Here's how I know I'm on the right channel: daniel@seasonBlack:~$ iwlist channel lo no frequency information. eth0 no frequency information. wmaster0 no frequency information. wlan0 11 channels in total; available frequencies : Channel 01 : 2.412 GHz Channel 02 : 2.417 GHz Channel 03 : 2.422 GHz Channel 04 : 2.427 GHz Channel 05 : 2.432 GHz Channel 06 : 2.437 GHz Channel 07 : 2.442 GHz Channel 08 : 2.447 GHz Channel 09 : 2.452 GHz Channel 10 : 2.457 GHz Channel 11 : 2.462 GHz Current Frequency=2.437 GHz (Channel 6) wmaster1 no frequency information. wlan1 11 channels in total; available frequencies : Channel 01 : 2.412 GHz Channel 02 : 2.417 GHz Channel 03 : 2.422 GHz Channel 04 : 2.427 GHz Channel 05 : 2.432 GHz Channel 06 : 2.437 GHz Channel 07 : 2.442 GHz Channel 08 : 2.447 GHz Channel 09 : 2.452 GHz Channel 10 : 2.457 GHz Channel 11 : 2.462 GHz Current Frequency=2.437 GHz (Channel 6)

Have to dhclient each restart to access internet

So each time I restart my ubuntu server (virtual 10.04, via Xencenter), I have to call dhclient before I can access the internet: http://img813.imageshack.us/i/dhclient.png/ What do I need to change to get internet access automatically?

vconfig created virtual interface and trunking - is the the interface untagged or tagged for that VLAN ID?

- by kce

I am trying to setup an additional VLAN on our Debian-based router/firewall (which exists as a virtual machine on Hyper-V), our core switch (an HP Procurve 5406) and a remote HP ProCurve 2610 that is connected via a WAN Transparent Lan Service (TLS) link. Let's work backwards from the network edge: The Debian server has an external connection attached to eth0. The internal interface is eth1, which is connected directly from our Hyper-V host to the 5406. The port that eth1 is attached to is setup as Trk12. The 2610 is attached to Trk9 (which trunks a whole slew of VLANs - Trk9 is our TLS head). I can successfully ping the management IP addresses for my VLAN from both switches but I cannot ping, from either switch, the virtual interface for my new VLAN on the Debian-base router and firewall. The existing VLAN works fine. What gives? The port eth1 is attached to is a trunk, the existing VLAN (ID 98) is untagged on the trunk, the new VLAN (ID 198) is tagged. VLAN 198 is tagged on Trk9 on the 5406 and on the 2610. I can ping the other switch's management IP (10.100.198.2 and 10.100.198.3) from the other respective switch. That leg of the VLAN works - however I cannot communicate with eth1.198's 10.100.198.1. I feel like I'm missing something elementary but what it is remains illusive to me. I suspect the issue is with the vconfig created eth1.198. It should pass the tagged VLAN 198 packets correct? But they cannot seem to get any further than the 5406. Communication on the existing VLAN 98 works fine.
