Routers forward multicast video packets so slowly

hey guys
I have a problem with multicast, here is the senario.
I have a video Server that sends streams in multicast to its clients. the clients in same subnet with server don't have any problem and receives streams clear but the clients that are not in same subnet which means their packets must cross the routers receive the streams so slow and not clear.
all of my routers are 3845 but my RP is 3945.
I changed all routers IOS but it doesn't fix the problem.
I enabled cef and MFIB on all router and on 3845 routers configurations are so simple, just setting sparse-dense-mode and MFIB in interfaces and rp address for global.
so I will thank anybody who help me for rest of my life because I kinda thinking about killing myself because of this problem.....it just doesn't make sense
and someone in other forum told me its MTU Issues, but how can i fix this
thanks

Well at least your 2nd post mentions tunnels and IPSec. For video, you may very well be having MTU issue across tunnels as video can often easily fill a packet.
Since the traffic is multicast, the only way I can see you avoiding fragmentation is reducing the MTU on the source video device.

Which Linksys VPN Routers support Multicast forwarding

Which Linksys VPN Routers support Multicast forwarding / passthru I have remote SPA942 phones connected thru a vpn to a SPA9000/SPA400 system. After manual provisioning the phones work, but voice mail, auto provisioning, etc that use multicast do not work. VPN is using Netgear boxes which do not forward multicast. I'm going to switch to Linksys/Cisco VPN routers but want to make sure which models will do the multicast forwarding.
Thanks

I only no of 1 for sure and that is by downloading 3rd party firmware like DD-WRT, the WRT54G. See the below Link.

How to protect a PIM-SM network from unauthorized pim routers and multicast sources?

Hi,
we're using pim sparse mode in a customer network with catalyst 2/3/4/6K switches, all multicast routers are redundant with pim dr running for access subnets. RPs are configured with anycast rp.
A) Is there any possiblity to prevent rogue pim routers/igmp queriers connected to host ports from getting connected to the legal pim routers and from getting involved in the local igmp traffic?
Maybe like DHCP Snooping used with DHCP. I read that in the latest Sup2T ios (http://www.cisco.com/c/dam/en/us/td/docs/switches/lan/catalyst6500/ios/15-2SY/config_guide/sup2T/15_2_sy_swcg_2T.pdf) there is a feature called 'ipv4 router guard' which does exactly what we're looking for:
'When configured, the Router Guard feature makes the specified port a host port only. The port is prevented from becoming a router port, even if a multicast router control packets are received. In addition, any control packets normally received from multicast routers, such as IGMP queries and PIM joins, will also be discarded by this filter.'
Afaik, PIM authentication isn't supported in current catalyst ios versions.
Using a normal port ACL is not an option in our case because of a management decision.
B) Is there any possibility to prevent (on a per-subnet basis) rogue sources from sending multicast streams to legal multicast-groups?
Maybe, can I configure a svi of a host subnet or a host port to drop any incoming multicast stream while still accepting IGMP and sending out legal multicast streams?
Using 'ip pim accept-register' command on the rp is not an option because we've tons of legal sources which would end in an very huge error-prone acl
Unfortunately, a normal ACL is not an option here, too.
Best Regards
Thorsten

We use two pim routers in each host subnet for redundancy, they elect the PIM DR.
Does pim passive mode work here?
(Config Guide: If the ip pim passive command is configured on an interface enabled for IP multicast, the router will operate this interface in PIM passive mode, which means that the router will not send PIM messages on the interface nor will it accept PIM messages from other routers across this interface. The router will instead consider that it is the only PIM router on the network and thus act as the DR and also as the DF for all bidir-PIM group ranges. IGMP operations are unaffected by this command. ... The redundant PIM stub router topology is not supported. The redundant topology exists when there is more than one PIM router forwarding multicast traffic to a single access domain. PIM messages are blocked, and the PIM asset and designated router election mechanisms are not supported on the PIM passive interfaces.)
ip pim neighbor-filter maybe would work to prevent rogue pim routers to connect to the legal pim routers but wouldn't rogue pim routers still be able to manipulate the layer2 switch to send all igmp traffic to them and not to the legal pim routers?

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

"RTMFP" connected to the FMS server,but may not play multicast video?

the question is,a client which can use "rtmfp" to connect to a FMS server,and the connecting success,Whether Can not guarantee that the client can play the Multicast video?
because the client may be behind a Special firewall ，So he may connect to the FMS server ,but can not use P2P to connect to the members those are in the group?
If the answer is "yes",Whether i should make a check function that make these client back to "RTMP"?

Video and audio slowly go out of sync

im trying ot make encore dvds the first one I made worked fine but now whenever I make a dvd the video and audio slowly drift apart as it plays.
ive tried converting the audio to AC3 but it did not help. Ive also tried various formats like vob, mp4 and avi.
does anyone have a solution?

This may or may not work but give it a try. I'm not sure what software you used to create the video file that you sent to Encore
but I'll assume that it is Premier CS3 or CS4.
Here's what I would do.
1) output your sequence two ways. a) seperate Mv2 & Audio file, b) One single AVI file. Use media Encoder, DO NOT USE DYNAMIC LINK!
2) Import each one into encore. NOTE: The mv2 file will NOT have to be transcoded.
3) Set each one up on a seperate timeline.
4) Play each time line. See if they go out of sync. If they do, make sure that you perform the following.
5) Place each timeline onto a menu. label each one so you know which is which (i.e., MV2, AVI)
5) Burn the project to an image file (don't waste a DVD).
Next try playing the DVD using a seperate DVD player (NOT ADOBE)
Test each timeline. See if they work or fail.
It sounds like a lot of work but once you know which way works, stick with it!

Video packets to a file.

Hi all,
I am using the xuggle library to get the frames of the video file. I am able to write those video packets into a swing window for playing the video. but I want to write those packets into a file. and if there is any way to create the flv file from the video packets that will be very helpful.

FAQ

Is there a Cisco lab available for ASR 9000
we have "XR4U" stations coming available soon when XR 511 comes alive. The plan is for a downloadable play image like that. In the interim we have 2 demo systems available, and they can be booked via your account manager representative.
How will MOD160 perform with multiple 9000NVS?
very well. the mod 160 has 4 NPU's, 2 per bay. So if you have a 4x10 MPA to serve a satellite, you effectively have a single NPU per 20 1Gigs from the satellite. The pps performance will be stellar. However it might be price technically more ideal to connect satellite with a 36x10. Since the MOD-x has native MPA's with 1G also.
2. Is there a shortcut for a Bundle-EthernetX interface, such as port-channel interface (poX), in Cisco IOS® ?.
usability enhancement is there, we are trying to push this into a new reasonable release. follow CSCuh04526
3. What is the revolutions per minute (RPM) on these hard disk drives (HDDs) compared to the solid state drives (SDDs)? Will the spinning drives be slow?
depends on the type we had avaialble at time of production, you will see different sizes and disks on the RSP2. the rpm of the HD is not so much an issue as much as the buffered writing we used to do in XR. This is fixed up with XR43 where the disk writing performance is much better. the HD/SDD is used for logging storage only (and maybe your pictures) but other then that we're not that concerned with write perf of the HD.

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).

Multicast: duplicated packets on nexus 7k with vpc and HSRP

Hi guys,
I'm testing multicast deployment on the lab shown below. The sender and the receiver are connected to the 6500 in two different vlans. The sender is in vlan 23 and the reciever in vlan 500. They are connected to the 6500 with a trunk link. There is VPc between the two nexus 7k and the 6500.
Furthermore, there is HSRP running on the two vlan interface 23 and 500 on both nexus.
I have configured the minimum to use PIM-SM with static RP. The RP is the 3750 above the nexus. (*,G) and (S,G) states are created correctly.
IGMP snopping is enabled on 6500, and the two nexus.
I'm using iperf to generate my flow, and netflow and snmp to monitor what happens.
All works correctly, my receiver receive the flow and it takes the good route. My problem is that I have four times more multicast traffic on the vlan interface 500 on both nexus but this traffic is only sent one time to the receiver (which is the good comportment) and the rest of the traffic is not shown on any other physical interface in outbound.
Indeed, I'm sending one flow, the two nexus receive it (one from peer link and the other from the 6500) in the vlan 23 (for example 25 packets inbound).
But when the flow is routed in the vlan 500, there is 100 packets on each interface vlan 500 on each nexus in outbound.
And when monitoring all physical interfaces, I only see 25 packets outbound on the interface linked with the receiver and the overflow isn't outgone.
I have joined the graphs I obtain on one of the nexus for the vlan 23 and the vlan 500. Netflow says the same things in bits/s.
Had someone already seen that? Any idea about the duplication of the packets?
Thanks for any comment,
Regards,

Hi Kuldeep,
If you intend to put those routers on a non-vpc vlan, you may create a new inter-switch trunk between the N7K and allow that non-vpc vlan . However if those will be on a VPC vlan, best to create two links to the N7K pair and create a VPC, otherwise configure those ports as orphan ports which will leverage the VPC peer link .

What is Best Practice for Publishing and Subscribing to Multicast Video P2P

Please, could someone help with an issue I am having in developing a peer to peer video chatting application? My application uses multicast to publish and subscribe to video streams of NetGroup members. I'm listening for the NetGroup.Neighbor.Connect event, and I'm calling the following function:
protected function onPeerConnect(event:NetStatusEvent):void{
                var peerID:String = event.info.peerID;
                // create user vo here
                // user Value Object for incoming stream
                userVO = new User();
                userVO.peerID = peerID;
                netGroup.addNeighbor(peerID);
                receiveStream(userVO);
protected function receiveStream(userVO:User):void{
                // init netstream
                var stream:NetStream = new NetStream(nc,groupspec.groupspecWithAuthorizations());
                stream.receiveVideo(true);
                stream.addEventListener(NetStatusEvent.NET_STATUS,netStatus);
                // init panel
                // alter to use custom component instead
                var panel:Panel = new Panel();
                panel.id = "panel" + panel_seq;
                panel.title = "Panel" + panel_seq;
                panel.width=322;
                panel.height=281;
                panel.x = 50 * panel_seq + 200;
                panel.y = 25 * panel_seq + 200;
                var cpanelContent:Array = new Array();
                panel.controlBarContent=cpanelContent;
                panel.controlBarVisible=true;
                // init video
                var video:Video = new Video();
                video.width=320;
                video.height=240;
                video.attachNetStream(stream);
                stream.play("media");
                // init videoWrapper
                var videoWrapper:UIComponent = new UIComponent();
                videoWrapper.id = "wrapper" + panel_seq;
                videoWrapper.addChild(video);
                // add to display list
                addElement(panel);
                panel.addElement(videoWrapper);
                // drag and drop panel
                panel.addEventListener(MouseEvent.MOUSE_DOWN,function(event:MouseEvent):void{
                    panel.startDrag();
                    addElement(panel);
                panel.addEventListener(MouseEvent.MOUSE_UP,function(event:MouseEvent):void{
                    panel.stopDrag();
                panel_seq++;// used for unique panel id
                userVO.panel = panel;// reference to the panel
                userVO.stream = stream;
                userVO.video = video;
                peers.addItem(userVO);
I am confused on this:
var stream:NetStream = new NetStream(nc,groupspec.groupspecWithAuthorizations());
What should I pass as the second parameter to establish an incoming NetStream with the publishing peer? I've seen people put in the farID but I haven't figured out how to access it. What is the difference between event.info.peerID and event.info.neighbor? And since I'm multicasting to the group do I need to pass in the groupspec or the farID? I would love some clarification on this.
What is happening is this:
When I join the group, and there are two members in the group already, I'll get three panels with videos. However, duplicate video streams are being attached. When I inspect the peerStreams array I'm seeing a length of 0, so does that mean that no one is subscribing to my published netstream? If so, how do I specifically subscribe to each published stream in the group? Sometimes if I step through in debug mode, I get three separate camera feeds in their prospective panels, but if I run it will have duplicates. I thought at first that this was a referencing error because all of the NetGroup.Neighbor.Connect events where happening all at the same time and perhaps that is the reason for the duplicates?
My only other thought is that maybe I'm multicasting one guys stream to the whole group, but I'm getting varying results so I want to know what is the correct way to grab, in sequence, a NetGroup members' published netstream and be sure that all other members are subscribing to my NetStream as well?
Also, I am using Value Objects to keep track of who my group members are, is that data shared with the group or is it not accessible to all members?   or should I use another method of keeping track of my group members?
Please help! Thank you in advance!

Cisco 2811 routers to route video over ip for polycom equipment.

Hi forum,
We are currently using polycom equipments over ISDN links for video conferencing, however, we intend to switch to our EIGRP E1 lines for that. all our sites are currently using 2811 routers to route both data and voip traffic. How do I provision the network so that I can use my E1 lines for video over ip, How should I design it?
Besides, How do i provide video over ip service to my mobile users who vpn into my network.
Thanks and best regards,
paul

first, on provisioning your network for video over ip, make sure you can implement the QoS required to provide a clear, unchoppy video stream.
your design could look something like the following:

No chapter fast forward for video playback in os7

Anyone else notice that you can't hit the fast forward button and jump to the next chapter in an iTunes video? I can go back to the menu and skip from there, but not while watching the video. Not a big glitch, but annoying. Why do the all the updates always have this bug? You'd think they would have tested them before hand.

It has always seemed that Bridge has been the stepchild of Adobe since its inception and that Adobe spends precious little effort and resources on it.
Remember that Bridge was born as nothing more than Photoshop's Browser. Nothing more.
Then, in a straight marketing stunt, Adobe decided artificially to lump together a number of totally unrelated applications into artificial "suites." These are in fact totally non-related applications that were artificially bundled by fiat of bean counters and marketers. The engineering teams for the individual point applications are totally independent from each other and are not only not in in the same building but in different cities, different states and, some, in different countries. They have pathetically little communication among themselves.
The humble Photoshop Browser was renamed Bridge and jerry-rigged to serve as some sort of go-between vehicle among the applications also jerry-ringed into artificial suites. (Definition of JERRY-RIGGED: organized or constructed in a crude or improvised manner <a jerry–rigged plan>.
Don't expect too much from Bridge, and don't complain about it too loudly, or you might find yourself among others who have been told, in effect, that "Adobe doesn't charge you for Bridge." As a "free" byproduct, you get what you paid for.
In this context, just look at what has happened to the value of Adobe stock in the last five years: –28.20% (minus).
Compare that to Apple during the exact same period: +358.43%.
