Multicast video on-demand

Hi,
I have a problem with my ip-cameras(Bosh, Axis and Sony). They all work nicely with unicast, but with multicast there is trouble as it follows:
-Bosh: Takes up to five seconds to join and get image.
- Axix: Up to 20 seconds.
- Sony: Under demand it creates the group (*,G) but never the entrance (F,G). I never get any image under multicast.
Anyone with a similar experience? Please, share and/or help.
All the best,
Fernando

As far as I know T-Home separates their VDSL Connections into different Virtual Networks.
There is one VLAN for Data and another one for TV.
In my opinion you will need a Router which is able to handle multiple VLAN’s on the WAN Interface.

Unable to Stream Video on Demand files from NAS on latest version of AMS 5.0.3

Hi,
I was hoping that someone could assist me.
Our organisation has recently purchased Adobe Media Server Standard to deploy to two Windows 2008 R2 servers (core edition) to stream flash content (video on demand only) which is resident on NAS storage.
I have considerable difficultly in streaming content from NAS and from the literature I have read and the configuration I have done it should be possible.
The steps I have taken to attempt to get this to work are as follows:
Installation
- Installed AMS 5.0.1 on both servers using the default TCP ports and Apache was not installed as part of the install
- Both AMS instances upgraded to the latest release AMS 5.0.3
- Windows Firewall on the servers disabled (we use hardware firewalls) and TCP connectivity verified by using telnet to connect these servers on 1935 and 80
Initial Configuration
- As we only will be using video on demand I removed the live, livepkgr and multicast applications from the /applications folder. Vod is the only application remaining
- Using the videoplayer in the /samples/videoplayer we were successfully able to view the sample streams
Configuration to stream from NAS
- I modified the VOD_DIR in the ams.ini file in the /conf folder to reflect the NAS location (\\{nas FQDN\sharename}
- Our NAS share has NTFS permissions applied and our AMS servers are joined to Active Directory. I created an AD account that had membership of the group that had read rights to the NAS share.
- I then reconfigured the AMS windows service to Log on with the AD account (as per the install guide: http://help.adobe.com/en_US/adobemediaserver/configadmin/WS5b3ccc516d4fbf351e63e3d119f2925 e64-7fc7.2.3.html)
Issues Experienced
- Whenever I change the AMS windows service to use an AD user (and not the Local System account), the service will run for only a short time (time often varies) before the service stops. In the application event log the AMS (Core) component
logs the error "Failed to create process mutex".
- The issue experienced is similar to a previous post by an FMS 3.5 user (http://forums.adobe.com/thread/650522)
Troubleshooting:
- To rule out a permission issue, I confirmed that the AD user created could actually read from the NAS share
- I also gave the AD user read/write permission to the AMS install directory. I have also added the AD user to the local admin group. Still get the "Failed to create process mutex" error and service stops.
- We created a test share on the NAS that had no restrictions set (everyone full control) and reconfigured the ams.ini to use this. The service still stops.
- I reconfigured the ams.ini back to the default path (local storage) and attempted to start the AMS windows service with the AD account. The service still stops which seems to confirm the issue is not related to the NAS storage/permissions itself
- I gave the servers machine account from AD read/write access to the NAS shares (both test and live shares) and reconfigured the AMS windows service to use the local system account. Whilst the windows service remains stable and runs,
streams do not work
- I have been testing using rtmpdump and a player (http://osmf.org/configurator/fmp/):
- With the player the player connects and the stream remains in a "buffering state"
- With rtmpdump we get the "NetStream.Play.StreamNotFound" error. The stream definately exists. I have the rtmpdump log file but not sure how to upload it to this post
- The above issues/behaviour is experienced from both servers
Workaround:
- The only way I can get NAS streaming to work is to map the NAS share as a network drive from the server
- On the same server I then stopped the AMS windows service and started AMS as a console application (ams.ini is pointing to the NAS location)
- Streaming then works however this is not an exceptable workaround for a enterprise server that will be streaming content to the Internet. Having to rely on mapped network drives and console applications is certainly far from ideal.
Should it be possible to have the windows service run under the context of another account and to be able to stream without then having to have a mapped network drive?
Any assistance would be greatly appreciated
Thanks
Jason
UPDATE: to add further, I have just tested this on a Windows Server 2008 R2 Standard edition with the full UI and I get the exact behaviour/problems as documented above. The issue I am experiencing is not related to the fact I am using the core edition of Windows.

HI,
I have managed to address my issue and get this working!
When reconfiguring the AMS service to use the AD account you MUST also reconfigure the Adobe Media Administration Server to use the AD account.
This mismatch in accounts was causing the mutex issue and stopping the AMS account from running. Read access to the NAS and log on as a service right on the AMS server
was all that required for the stream from NAS to work.
If any Adobe staff read this thread - can I please request that the section on "Mapping Directories to Network Drives" in the "Configuring the Content Storage" section of the help guide (http://help.adobe.com/en_US/adobemediaserver/configadmin/adobemediaserver_5.0.3_config_adm in.pdf) be revised to be clearer as to what windows services need to be reconfigured
to support AD authentication
Thanks
Jason

FIOS TV Multi Room DVR Video On Demand errors

I recently activated FIOS TV (already had FIOS Internet and Freedom phone) and received 5 STBs (1-QIP7216-1 DVR, two HD STBs a second HD DVR (QIP-6400 and a standard def STB) connected via COAX (MoCA) to an Actiontec Gen2 wireless router. Since the TV service install 1 month ago I have been on the phone with FIOS tech support at least a dozen times trying to resolve intermitent internet connectivity problems and most recently issues with FIOS TV features (i.e. Video on demand and multi-room DVR configurations). The Video on Demand issues would manifest as VOD_6 (request timeouts). Each time I worked with tech support to reset the router, power off the STB, etc and sometimes the VOD service would activate.
Last week VOD failed again and the FIOS tech I spoke to was havnig difficulties remotely connecting to my STBs (a common situation from previous tech support calls). He dispatched a technician to visit my home to check DB levels for each of my STBs. The field tech arrived two days ago and brought a new QIP7216-1 and a new router. It took over an hour for him to get them working even with help from remote support (they couldn't "see" the STBs). Once they were able to flush out the issues, he departed but unfortunately he left without enabling the multi-room DVR functionality. I called FIOS support yesterday and the remote technician had significant difficulties getting the "system" to recognize my configuration and he eventually broke off our call so he could escalate to Video support. He called me back hours later once he felt that they had resolved all the configuration issues and when I checked everything seemed to be working.
This morning I tried to program my DVD from my Verizon cellphone (this was working last week) and the DVR displayed a message that my account was not authorized. I called into FIOS support and the automated service attempted repair which included a "reload" of the STB firmware. Once the automated system felt I should be able to continue I noticed that the Video on Demand error VOD_5 happened when I tried to select it and now the option for Remote DVR programming is nolonger available on any menu!
I called back to tech support and the technician had me unplug and restart the STB but he was having issues remotely accessing the STB. He broke off the call explaining that he needed to escalate to Video Networking specialists and I'm awaiting his call back.
I am wondering if my experience is common and whether someone else has encountered (and resolved) these frustrating issues. I can't believe that Verizon expects users to have to re-boot routers and STBs anytime a feature is accessed. Hopefully one of the Verizon employees who monitor these forums can see some commonality and suggest a course of action that will bring relief. I have spent more hours troubleshooting my configuration than I've enjoyed the entertainment offerings, Please help!

Hi gr8scot,
Since my original post I can attest that I've made it through 2 weeks without any error messages or unavailable features (fingers and toes crossed) . I can identify with your frustration and hope that once they exorcise the demons from your configuration (if you hang on) it seems that eventually the solution stabilizes.
In my case I found some help by contacting the Verizon Customer Relations team at 800-483-7988. Once I got these folks engaged I can say that my blood pressure returned to lower levels as they were in daily communications with me until I was satisfied that my issues were resolved.
It's unfortunate that it had to get to that point for me (and for you too) but it was fairly apparent that something about my equipment configuration was confused within the Verizon FIOS provisioning applications (my issues seem to have developed around the time of any equipment or service changes). I spoke to some very dedicated and personable FIOS tech support agents (unfortunately I actually got to know them very well after spending hours on the phone). It was clear to me that they were doing the best that they could and the issues were way above their toolset and my big beef was the lack of communication that happened once the first level folks had to pass the problem off to either the "network group" or the developers.
Good luck and hope we both can eventually get to enjoy our entertainment systems.

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 )

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"?

Can a client in a video on demand system broadcast the same video stream which received from others

Hi All,
It's critical that a client in a P2P video on demand system can act as both a receiver and a provider, is this possible in flash P2P?

not in Flash Player 10.0.

Distortion in video on demand

Regular HD and standard proms are clear, but whenever I attempt to use Video on Demand the picture is distorted. Is anyone else having this problem? Is there a fix?

Usually I would suggest rebooting the router first along with the cable box if this begins to happen.

Please help me with video on demand project

I'm currently doing video on demand system and facing one big problem:how to do BACKWARD and FORWARD the movie.
I have tried with the setRate method and it doesn�t work. I would like to know if my code is wrong. Here it is:
public void controllerUpdate(ControllerEvent e){
try{
if (e instanceof ConfigureCompleteEvent){
TrackControl[] atc = pr.getTrackControls();
for(int i = 0; i < atc.length ; i++){
System.out.println(atc.getFormat());
atc[1].setEnabled(false);
atc[0].setFormat(new VideoFormat(VideoFormat.H263_RTP));
pr.realize();
}else if (e instanceof RealizeCompleteEvent){
pr.prefetch();
}else if (e instanceof PrefetchCompleteEvent){
pr.setContentDescriptor(new ContentDescriptor(ContentDescriptor.RAW_RTP));
DataSink dat = Manager.createDataSink(pr.getDataOutput(),new MediaLocator(destino));
dat.open();
dat.start();
float vel=(float)5.0;
float f=pr.setRate(vel);
pr.start();
System.out.println(pr.getRate());//The value returned is 1.0
}catch(Exception ex){
System.out.println(ex);
If the code is right, could it be that setRate doesn�t works with some formats of media?
Need your help urgently.
Thank you.

I don't see any obvious programming errors, but according to this -
http://java.sun.com/products/java-media/jmf/2.1.1/apidocs/javax/media/Clock.html#setRate(float) - it's possible that something could have started the Clock. Check for a ClockStartedError.

Problems with Purchased Video-On-Demand

Hello,
I purchased a movie from video on demand and it is not playing properly.
I have used on demand many times (although not VOD - I've used HBO & Showtime On Demand, etc.).
When I go to view the movie, the screen is all choppy, and I can still see the On Demand interface channel in the background.
If I rewind or fast forward the movie, the picture is crystal clear, however when I hit play I have the same garbled picture. There is also no sound.
I tried stopping and restarting the movie, testing a different On Demand channel, and restarting my cable box, all to no avail.
Does anyone have any suggestions?
Thanks so much!

You said you tested another VOD... Did the other have the same issue, or not?
Unplug power from the Set-top box and router for a few minutes..... PLug them back in and try again... if still not, then remove power from the STB and reset the router with a paperclip or pen in the reset hole on the back of the router for 15 seconds... turn them on and try again
If that does not resolve the issue, contact tech support and have them try to reset the STB and possibly reboot the ONT, and then go from there

Video On Demand Link

Looks like my box has lost the link to my Account for Video on Demand. It want me to rent tv shows.On Demand has been down for two days.

There are two solutions here that I see, but one is probably more reasonable than the other. Without the use of a streaming media server, you can't really record video/audio. However, the FLV spec is open source and you can accomplish a "recording" by writing bitmap data bytes to a flv file (using the open source spec). This won't capture the audio though, and you can't do that without a streaming server. Also, if you're recording long videos, chances are the writing will either make your application unresponsive/crash it, or the saving time if you broke it down to manageble chuncks would take forever.
The second option, probably what you want, is a streaming server. Whether it be Red5, Wowza, FMS, etc, you'll be able to accomplish what you want, and it should be fairly easy. All be it much more expensive. For what you're describing though, recording live streams, it is probably the most likely approach.

Pull based video on demand?

hi to all, i am developing a p2p video on demand application(pull based)..since it is pull based,how a receiver can control the streaming?.. is there any reference..
how can i use RTSP commands from receiver?.. please answer me
i have 2 questions
question1:
how to initiate video transmission from sender by a receiver(how to initiate pull based streaming)?
question2:
is it possible to stream video inside same system using avtransmit and avreceive ?

question1:
how to initiate video transmission from sender by a client?The sender would need to keep a "request" port open, listening for client requests. The client would send a request to the sender, and the sender would then kick-off the transmission in response to the request. There is actually a whole lot of handoff that needs to happen in order to get the whole thing working.

I figured it out.
It has to do with nested items using 3d functionality.
I had sprites loading the images which I in turn addChild to another sprite (so I could offset the position before rotation).
As soon as I changed my
holder.addChild(image);
to
addChild(image);
... my problems disappeared !
This means I have to change my concept a bit, or at least rewrite the code - but at least the stuff stays on screen.
I really hope this issue gets sorted out.
Hope you figure your issue out as well.
