Multicast video over wirelss problems!!!

I have media service server transmit video using ip multicast I have Cisco routers 2800 and 3350 and I am enable PIM dense mode and multicast routing also enable , I am using Cisco switch 2950 and I enable IGMP snooping .
in such situation my video service is working well but .........the problem is when I transmit the service through wireless using Cisco AIRONET 1300 (average ping time 30ms ) my video service is distortion . please,is there any body may help me ?

Basic (default)?Allows transmission at this rate for all packets, both unicast and multicast. At least one data rate must be set to Basic.The slowest basic rate is the rate that 802.11 management packets are sent. It is generally thought that management packets should be sent a the lowest rate. But, these are application devices and should be set to best
fit the application(s).

Video UDP Multicast over Aironet problems

I am currently able to transmit several 3Mb/s video feeds over cat5 ethernet and receive them. But when i try to send the data over aironet access points the video data is incomplete or corrupted during transit resulting in damaged pixels at the viewer end.
is it even possible to send multicast video data over wireless?
i have been told that there are firmware updates available on other manufacturers AP's, i still need to substantiate this.
I am looking for some help with regard to multicast video over aironet AP's.
thanks in advance for anyones help.

Aironet access-points are simply layer-2 bridges/repeaters. they support "multicast" just as an ethernet hub does.
Multicast and wireless are not always friends. With multicast and wireless we send out all multicast traffic and the minimum bandwidth that all clients are associated at. For example if one user is connected at 1mpbs and all other users are connected at 11mbps then all multicast is sent at 1mbps. Now lets say that you are only sending data at 11mbps, and you are sending three MPEG 1 video streams at 1.5mbps, that would give to a total bandwidth of 4.5mbps then this will not work. If they are using small cast and not multicast and you have 1 video stream at 1.5mbps being set to three sites, the total bandwidth would be 4.5mbps again it would not work. If you only have 1 video stream set up as multicast and you set QOS on the video via priority filters this might just work. Bandwidth, QOS, connection speed, type of connections (bridge or workgroup bridges), small cast or multicast, this all matters.

Facing Problems in Streaming Video over internet using FMS 3.5

I,am using FMS 3.5 to stream video over internet.This video will be a part of a website www.mywebsite.com . I have the webserver in my company. This webserver has the local LAN IP : 192.168.10.19 which is binded with a public internet ip 212.77.xx.xx .This website is hosted using IIS 6.0 on OS windows 2003 server with SP2
I created a swf name sample.swf from sample.flv file and gave it the rtmp address as follows:
rtmp://192.168.10.19/vod/_StreamingVideo_/sample.flv (where _StreamingVideo_ is the instance on the server, and 192.168.10.19 is the LAN IP of server) ,and it worked fine and every one within the local company network could see the streaming video. Now i tried to replace this local address with the public address and the address became as follows:
rtmp://212.77.xx.xx/vod/_StreamingVideo_/sample.flv
After giving this public IP in the rtmp address i,am getting a message "Failed to load Flv from the address rtmp://212.77.xx.xx/vod/_StreamingVideo_/sample.flv" and as as result the video is not streamed and it only shows the progress bar on the link
www.mywebsite.com/VideoStreaming/Sample.html without loading the video. I have also checked the ports 80,1935,1111 on the server and they are open. Is there any problem with my rtmp address with public IP or any other reason ??. Please help me out in this regard because im realy stuck here.

Adding to my previous post this is the XML output i get when i try to access the fms admin console from local ip address i.e http://192.168.10.19:1111/fms_adminConsole.htm
<?xml version="1.0" encoding="utf-8" ?>
- <result>
<level>error</level>
<code>NetConnection.Connect.Rejected</code>
<description>Admin user requires valid username and password.</description>
<timestamp>2/3/2010 8:26:08 AM</timestamp>
</result>
but when i try to access fms admin console through public ip (http://212.77.xx.xx:1111/fms_adminConsole.htm) then it gives me the following :
Internet Explorer cannot display the webpage.
Any more suggestions Jay (because really ur the only one helping me out in this so far) ??

Horrible video skip / lag problem - once per second in all apps!

I built a new system last month (my first AMD) and I am having a really aggravating problem. In all games and all video playback I get an annoying skip once per second, every second. It affects sound during gameplay but not during movie or mp3 playback. It even happens with the visualization mode in Windows Media Player.
My system is as follows: MSI K8N Neo4-F, A64 3200+ venice core, MSI 6800GT 256MB PCI-E, two sticks of Corsair valueselect DDR400 512MB each, 500 watt PS, 160GB 7200 SATA HDD. Most recent NVIDIA drivers for everything. WinXP Pro with SP2 and all updates, DX9C. Nothing overclocked, all settings standard.
I have tried the following solutions:
1) BIOS upgrades, started with 1.4, installed 1.5, MSI tech support gave me 1.6b2 and I installed that. No luck with any of them.
2) Memory, installed per MSI directions, but I've tried all legal combinations, including one stick at a time. No change.
3) full format and reinstall of WinXP. No luck.
4) Switching between WinXP IDE drivers and NVidia drivers, with and without RAID drivers, No luck.
5) Removal of 6800GT PCI-E card and replacing with Ancient 8MB PCI Permedia2 video card. Problem still persists.
6) Disable onboard sound and LAN. No luck.
7) Running Fedora core 4 on second partition. Installed Nvidia video drivers, tried some games. THIS WORKS! No hitch, no skip, no nothing. Framerates are noticably slower but very stable. In WinXP I saw framerates bounce all over the place, from 230 FPS down to about 70 with one game. That same game on Linux ran smoothly at about 166 FPS with only occasional slight drops. The big FPS drops in Windows usually came right after one of the skips but didn't occure after every skip.
Right now I'm stumped. Linux uses totally different drivers for sound, LAN and SATA support. Some of those drivers don't fully use the Nforce4 chipset's features, maybe that's part of the difference.

Thanks TireSmoke:
I had found that sticky, but I took your advice and went thorugh it in detail last night. Lots of great info, fixes tweaks and tools, sadly none of them fixed my problem. The lag problem most people are reporting is not really like the wierd problem I am having. I have tried the recoommended fixes with ablsolutely no change in my system's behavior.
I am beginning to suspect a faulty motherboard component.
Russ_XP:
I think you are correct about fast writes. I googled the heck out of that last night and couldn't find any reference to enabling or disabling fast writes on PCI-E.
The drive is SATA-1. The Neo4-F is not SATA-2 enabled (there is a hack for it though). From memory I think it's a Western Digital WD1600-something, 7200 RPM dirve. I've tried it on both SATA buses and tried disabling the unused bus in BIOS.
I'm pretty sure I can dig up an old PATA drive somewhere and give that a try.
Gpalmer:
True enough, and I don't have these problems under Fedora. Sadly this is a cross-platform game development box, I need both XP and Fedora working.
Black_God:
Nope, this is a clean install. Although I wonder, could any of the built in XP update and security tools be causing this? I have disabled Windows firewall and virus protection monitoring.

The QT movie opened promptly for me in Firefox 4.0. The fact that it's intermittent for you with FF indicates that it's a connection issue and not an iWeb issue. For some reason not all of the files are being loaded by FF at those times. (The server is probably being run by an Ohio State graduate )
OT
Go Blue!
Note: using Quicktime for you slide presentation will exclude all those users from the dark side who don't have Quicktime installed on their PCs. You might look into a java based method for the presentation. There are lots of them out there. With the free Jalbum you have over 100 themes/skins to choose from.

Anyone has a sample script of multicast video chat in php using Cirrus

I was trying to create a multicast videochat from Videophonelabs sample and the reg.cgi in cgi-bin is nothing but a problem. I don't know much about this old outdated cgi thing. I wasted so many hours with errors on some funky database created by Sqlite3 which some servers don't even bother with.. Can someone post a working sample of multicast video chat in PHP?MySQL using Cirrus? No opensource RVC codes like that as they are all are for dating and adult chat. Looking for a decent multicast script with no Phython!
Thanks.

here you are php id manager with sqlite, but it's not a big problem with converting it to mysql, the same sql queries: https://github.com/delosgatos/P2P-ID-Manager-for-Video-Chat-Sample-from-Adobe-Labs

Playing IP Multicast Video Stream

I want to get an app that allows the iphone to receive and display an encoded video stream. The video stream could be coming over 3G or over WiFi. It will be an UDP/IP Multicast stream with an address in the 235.239.0.1 range. The VLC laptop version will receive and play the stream, but so far I cant find an iPhone app that will do it (VLC for iPHone will not receive a multicast stream over WiFi). Please help.

Streaming iTunes (shared library) video over ethernet...

I'm hoping someone with combined iTunes and networking savvy might be willing to help me out here. Here's the setup,
I have an Intel iMac hooked up to Fantom 1TB drive via USB 2.0 (iTunes library on external). The iTunes library is shared to an iBook G4 over ethernet via a Linksys Wireless B router (but both comps are wired in for max speed). (To be clear, when I say 'shared' I mean that I open iTunes on the iBook with it's own library and select the shared iMac library from within the iTunes GUI). When I go to play videos over the shared library on the iBook they are quite choppy and slow and I'm wondering where the bottleneck is.
I'm using Cat5e cable (1000Mbs+ so far as I can gather), but the router ports are 10/100 as is the ethernet port on the iBook (max 100Mbs). Further, the iBook has only 32MB of VRAM (although I've upgraded the RAM to 1.12GB). The iMac is running Leopard 10.5.5, iBook running Tiger 10.4.11, both machines running iTunes 8.0.1. I'm presuming that the read and transfer rates of the external are not the issue here because there are no problems viewing on the iMac, but I could be wrong.
So is the bottleneck the 10/100 ethernet ports on the router/iBook, the iBook VRAM, or is there something inherent in iTunes library sharing itself that is causing the delays? I also have an Xbox 360 which reads the same shared library via Rivet/Connect360 over the same network and router and videos are fine on the Xbox which makes me think the problem is with the iBook or iTunes.
I ask because I'm considering upgrading the router, and even replacing the iBook, but if it's something to do with iTunes itself, then there's not much point.
Thanks to any and all who can offer advice.

This evening I tried to narrow down the problem further and I think it boils down to the iBook not being able to process the video data fast enough rather than the transfer rate over the network or something inherent in iTunes.
To do this I shared my library folder on the network and copied a file from it to the iBook's HDD, adding it also to iTunes locally on the iBook. The quality is the same whether I view it:
1) Through the iTunes GUI 'SHARED' library over the network
2) By opening it directly (using Quicktime) over the network through the mounted shared folder in finder
3) Viewing it in Quicktime directly from the iBook's internal HDD
4) Viewing it locally in iTunes from the iBook's HDD
Now the question is whether the iBook should be able to view this video smoothly given its hardware, or do I have the logic board VRAM problem that I've been reading about...I guess an issue for another post/topic.
Thanks for trying to help Tom.

Streaming video over http

Hello
I need your help to understand how streaming over http works
In our company we have about 600 users who will be able to view streaming video over http hosted in Internet
We have 100 Mbps Internet link . What can we expect to happen in the network when there is contention for resources to access video on our network which delivers best effort service for video
We have enough bandwidth 4 gigs in local area network to core , so there's no real bandwidth cruch
How to differentiate or monitor bandwidth used for http streaming as against http normal traffic
Sent from Cisco Technical Support iPad App

One step closer:
Changed the crossdomain.xml file (more permissive settings).
Changed the encoding on FMLE to vp6. Working somewhat (don't know what I did to make it start streaming through hds).
But at least now I can get the individual streams in the set manifest file to work:
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream1.f4m
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream2.f4m
http://localhost/hds-live/livepkgr/_definst_/livevent/livestream3.f4m
BUT when I try to play the streams through the set manifest file from http://localhost/liveevent.f4m I'm getting the following error:
"The F4m document contains errors URL missing from Media tag." I'll search the forums to see if anyone else has come across this problem.
I used the f4m config tool to make the file. These are the file's contents:
<manifest xmlns="http://ns.adobe.com/f4m/2.0">
<baseURL>http://localhost/hds-live/livepkgr/_definst_/liveevent/</baseURL>
<media href="livestream1.f4m " bitrate="200"/>
<media href="livestream2.f4m " bitrate="500"/>
<media href="livestream3.f4m " bitrate="1000"/>
</manifest>

Loading a video over HTTP

I'm having problems loading a .3gp video over HTTP. I get the
following error message "Error preparing video for playing".
Everything else (xml data, images) loads nicely. I've tested
this with Nokia 6630 and N70, but with no luck.
If I transfer the files to my phone and load the video from
the memory card, it works just fine. Is there something I can do to
fix this?

Ciao
the defualt streaming protocol for Nokia is rtsp not http. So
it will not work an http call to a video.
Also using rtsp requires a streaming server, it's not enough
to place the video file on the server.
Other phone might use http for streaming.

IPad air has trouble streaming videos over Wi-Fi when Bluetooth is enabled

With Bluetooth enabled several video streaming apps have trouble. Videos are intermittent and choppy. But when I turn Bluetooth off, the problem goes away immediately. I'm streaming videos over Wi-Fi, and I tried changing the channels of the Wi-Fi network, but nothing seems to help. I've also tried switching video streaming apps with no difference. Has anyone else noticed these problems with Bluetooth?

Hey,
I have the same problem!
Apple, do you have an answer for this? How can we fix this?

Can not view video over the Internet on WVC80N

I set up the web cam, set up the port forward etc so now I am able to:
   1. view/change web cam settings inside my home network.
   2. view video inside my home network.
   3. view/change web cam settings over the Internet.
But I am not able to view video over Internet. Every time I did so (using IE browser), after clicking the view video button, I got an error : There are too many user connections or the device is busy, please try again latter.
Anyone has a fix on this? I set up port forwarding on port 1024 (that's how I can chage settings over Internet).
I spent 2 hours on the phone with Linksys tech support but they could not find the reason.
Thanks,
Sam

Who is your ISP? How you are trying to access your Camera from the remote location? Along with Port 1024 you need to do port forwarding for port 80 on your router for the Cameras IP address. As WVC80N works on your HTTP Port.
To access your camera from the Remote location, you need to use http://wan ip:80.

This is easily done with dial peer statements . The dial peer in your originating router must route the calls to the terminating router first. That would look like :
dial-peer voice xxxxx voip ( the xxxxx is just a tag)
destination-pattern 45... (that would route any 5-digit calls beginning with 45)
session-target ipv4:xxx.xxx.xxx.xxx (ip address of the terminating router)
If digitones are to be dialed after the connection is established, use the statement:
dtmf-relay-h.245-alphanumeric
You could also use a statement to specify the codec to be used:
codec g711ulaw
You would need multiple voip dial peers if the calls were going to different routers based on the dialed digits. If all calls are sent to the same terminating router, use all wild cards in the dest-pattern statement.
At the terminating router configure pots dial peers:
dial-peer voice xxxxx pots
dest-pattern 45...
port x/x (whichever port the call is to be terminated on)
prefix 45 (this re-inserts matched digits which are stripped off by the pots dp)
Repeat for other ports which will receive calls.
