ACNS 5.1 WMT Streaming

Hi
I've searched the messages trying to find out why a CE 7305 I had working with WMT isn't any more.
I have in the past just used a manifest file to read the content to the CDNFS. I then use Windows Media Player to call the file via MMS:\\server\folder\video.asf
When you browse to the CE directly (a'la port 8003) use reporting, WMT streams, active streams you can see MMS streams for the video and the IP address.
Reading past posts, people are suggesting you have to use .asx files to cause the browser to redirect.
Is this actually the case? What I'm after is the ability for the user to click a link and then for it to stream from the CE having pre-positioned by a channel. I have had it working in the past without .asx files, what I don't understand now is why its stopped working.
Manifest is: -
<?xml version="1.0"?>
<CdnManifest>
<server name="source-tag">
<host name="ftp://10.208.84.147/"
proto="ftp"
user="user"

Many thanks for any help,

I am not have an experience in your part , But I hope the following information and the link will help you more. Using Windows Media Technologies Microsoft Windows Media Technologies (WMT) is a set of streaming solutions for creating, distributing, and playing back digital media files across the Internet. WMT includes the following applications:
Windows Media Player--- End user application
Windows Media Server----Server and distribution application
Windows Media Encoder-----Encodes media files for distribution
Windows Media Codec----Compression algorithm applied to live or on-demand content
Window Media Rights Manager (WMRM)---Encrypts content and manages user privileges

WMT stream splitting (with multicast stations)

Hi,
I've created a WMT multicast station on my CE for live streaming splitting. Based on sniffer traces, the CE can receive both unicast and multicast streams from my WMS server. It also multicasts the unicast or multicast stream from the WMS server to the multicast address that I supply in the wmt multicast station-configuration command. However, the CE does not create the .nsc file for clients to access the CE-generated multicast stream.
When I enter the command :
show wmt diagnostics header-info nsc-file mynscfile.nsc
I get:
open: No such file or directory
unable to open mynscfile.nsc
Any ideas?
silvano

Stream splitting technically involves multicast. If you want unicast to unicast, it would not be stream splitting, it would just be individual clients each requesting a copy of the stream. See if this link helps you. The server side of the CE needs to be told to come in via unicast or multicast, then out to clients via either unicast or multicast.

Content engines, WMT and MPEG-4

I have successfully enabled WMT streaming on my CE and by contacting the CMD I can stream MPEG1 and various MPEG trailers I have gotten from the internet. Recently, I have encoded some content I captured and converted to MPEG4. When loaded and accessed via WMT, Media Player downloads the entire clip before playing. Normally, there is a small wait and then the Player will start showing the clip before it is completely downloaded. Is it true, that WMT will not stream MPEG4 files?

the mp2 compressor inside a DVD is a delivery format, not meant for further processing as editing...
a conversion from VHS directly to iM's native, internal format "dv" would be much better...
a conversion from one lossy format as mp2 to another (as Handbrake's mp4 or Divx or whatever) makes another conversion neccessairy => loss of pic quality...
to import/convert DVDs, you have the following options:
* DVDxDV (free trial, 25$)
* Apple mpeg2 plugin (20$) + Streamclip (free)
* Cinematize >60$
* Mpeg2Works >25$ + Apple plug-in
* Toast6/7 allows converting to dv/import dvd, hit apple-k
* connect your Camera to a DVD-player and copy to tape/use as converter

Streaming WMT (netshow) through PIX with Cache Engine

Hello:
I am trying to stream WMT from a pre-loaded Cache engine through a PIX firewall. I would like to use UDP for the streaming, but when I start the streaming TCP is selected by default. Forcing UDP within Windows causes an error. The PIX doesn't allow the UDP traffic through since it didn't originate from the inside. Outside the firewall UDP only works if I force it. TCP is the default. First, is UDP the best way to do this or is TCP ok since it is comming from the Cache engine? Second, how can I change the Cache engine setup to default to UDP or is this not possible?
Thank you,
Hampton Saussy
Midlands Technical College

We had a similar issue. If the firewall is not configured to accept TCP ports, then the streaming video server will perform HTTP cloaking i.e Instead of using the TCP ports it will use HTTP port 80 to get through the firewall, then the server sends the streaming video data via UDP. If UDP cannot pass through the firewall, the client requests delivery via TCP. The fixup rtsp command lets PIX Firewall pass RTSP (Real Time Streaming Protocol) packets. This command does not fix RTSP UDP connections. So I guess using TCP is a better option.

MMS:// port 554 with ACNS

I have my CE setup and have the wccp setup on my router. I see that WMT is being redirected if I use http:// to access the video. If I try to go straight to the video using MMS:// (Windows Media Service) it plays from the original site not the CE. MMS:// uses port 554. Is there a way to redirect traffic based on this port number? How can I get the MMS:// request to redirect to the CE?

Are you using WMS9? Starting with Windows Media Services 9 Microsoft decided to use RTSP-based streaming instead of the previously used MMS.
From the docs:
With WMS 9, Microsoft introduced a major change in the streaming protocol. Windows Media Services 9 Series by default uses a new RTSP-based protocol for streaming.
These are the streaming protocols currently used by Windows Media 9 players:
â¢Windows Media Services 9 Series RTSP/RTP-based protocol
â¢Windows Media Services 9 Series-over-HTTP
A Content Engine, which is running the ACNS 5.5.1 software, has full interoperability with the Windows Media 9 server and a Windows Media 9 player over all of these streaming protocols.
So if you want to configure WMT in ACNS 5.5 you need to enable service 80 and 83
Take a look at the procedure:

ACNS with DME2000 encoder

I am trying to figure out how to configure the DME2000 to send a unicast stream of LIVE TV to the ACNS network and distribute this to clients via multicast from a CE. I have seen numerous docs on ACNS and DMM but I am missing the fundamental flow of the data patterns.
How does the content actually get sent to the CE from the DME? Is it via a PUSH or PULL to the content engine? What is the method of transport? Is it MMS, HTTP, RTSP?

ACNS basically supports native WMT, Real and Quicktime streaming. Flash can be supported via progressive downloads via HTTP and played locally on the desktop. You would have to enable webcache and manage the streaming/downloads via HTTP.
Hope that helps,

ACNS 5.5 / Troubleshooting bad quality VIDEO (MMS-over-http)

Hello community,
For an unexplanable reason I have to deal with an ACNS problem which is not my domain at all ! ACNS 5.5.15 is on a WAE-512-K9 working with CDM.
Please can someone advice me on how to start the basic troubleshooting steps on the following issue :
============================
- Users in Sydney are complaining of bad quality when they watch a video from an Intranet server in Frankfurt.
Video flow has bad quality (buffering ..) and/or stops before the end of the video.
- Users browsers are configured to use the WAE as local proxy on ports 3129 (.pac file). Requested Video on the intranet is in the Windows Media format and flows are MMS-over-http.
- No multicast distribution is used, neither content pre-positioning.
============================
We did a wireshark trace on the user PC watching a video which ends up unexpectidely with error code 500 => We follow the TCP stream, Time/Sequence graph is linear until ACNS sent [PSH,ACK] tcp flags to the user PC. Then PC answers with [FIN, ACK] etc...and the stream ends.
I have checked the show-tech (i have attached some commands from the sh tech) especially TCP statistics but I do not if the values are normal or not.
I am thinkink to open a TAC case but before contacting Cisco I prefer to try some basic tests if they can help.
Any recommendation on how to start a troubleshoot or any advice would be gretly appreciated.
Thanks.
Karim

Hi Defcom,
Thanks for the quick reply. I have tried changing and resetting the bandwidth limits at both ends last week at both ends but no joy!
I am going to try the solution on the Gerry's link above later but have to wait for my brother to be free as he has an airport as well(had a baby yesterday (hence why we are setting this up)).

WAE 612 + ACNS 5.5.5 Help

I've been trying to setup a WAE 612 w/ ACNS 5.5.5, and I've run into a few problems. The goal is to setup a transparent forward proxy for WMT files. This is a standalone unit. The edge router that this device is hooked up to is a Cisco 7206VXR running IOS 12.4(12).
Initially, I configured WCCP outbound redirects on the WAN facing port of our edge router, and WCCP traffic seemed to be generated between the content engine and the router. `show statistics wccp gre,` it would return something like the following:
Transparent GRE packets received: 54919
Transparent non-GRE packets received: 0
Transparent non-GRE packets passed through: 0
Total packets accepted: 1134
Invalid packets received: 0
Packets received with invalid service: 0
Packets received on a disabled service: 0
Packets received too small: 0
Packets dropped due to zero TTL: 0
Packets dropped due to bad buckets: 0
Packets dropped due to no redirect address: 0
Packets dropped due to loopback redirect: 0

Packets sent to another CE: 0

Packets failed GRE encapsulation: 0
Packets dropped due to invalid fwd method: 0
Packets dropped due to insufficient memory: 0
Packets bypassed, no conn at all: 0
Packets bypassed, no pending connection: 53785
Packets due to clean wccp shutdown: 0
Packets bypassed due to bypass-list lookup: 0
Packets received with client IP addresses: 0
Conditionally Accepted connections: 0
Conditionally Bypassed connections: 0
L2 Bypass packets destined for loopback: 0
Packets w/WCCP GRE received too small: 0
Packets dropped due to IP access-list deny: 0
Packets fragmented for bypass: 21
Packet pullups needed: 21
Packets dropped due to no route found: 0
Unfortunately, when the clients attempted to call up a WMT video, it would go through the process of buffering, initializing, and going to a ready state; but the video would not play. The 'show statistics wmt all' would only increment the error counter with each play attempt; none of the other statistics from this command would change.
Next I attempted to just set this up as a non-transparent WMT proxy and configured an individual test Windows 9 Media client to reference the WAE as an RTSP proxy. It experienced the same problem as above. 'show statistics wmt all' would still only show error count increases with each attempted video, but nothing else would increment. This leads me to believe that the problem is not WCCP related, but something with my WAE configuration. I can successfully traceroute from my WAE to the video server; likewise, I can traceroute without problems from the WAE to my Windows media client machine.
Also, when I do commands such as 'show statistics mediafs,' the values for 'space used by WMT proxy' sometimes increments for an attempt to load a video; at best, the increase is about 12KB.
Here's the current WAE configuration file:
contentengine#show running-config
device mode content-engine

HTTP Streaming and BitmapData.draw

Hi OSMF Experts,
I've tried to duplicate segments of a Video with BitmapData.draw.
It's working with RTMP (set videoSampleAccess server side).
Progressive is also working (crossdomain.xml is ok).
BitmapData.draw doesn't work with HTTP Streaming! (Using *.f4m). What's the way to get this working? Following Error is thrown:
SecurityError: Error #2123: Verletzung der Sicherheits-Sandbox: BitmapData.draw: file:///C|/players/myVideoTestHTTP.swf kann nicht auf null zugreifen. Es haben keine Richtliniendateien Zugriff gewährt.
I've used OSMF 2.0 for the Tests. And I've testet with the sample.mp4/manifest.f4m example.
Thanks for your answers.

Have you seen bug CSCdx31582- Macintosh wont play WMT from CE (ecdn). Guess this is similar to the issue that you have.

Content Engine NM ACNS/network access

After searching Google and Cisco, here's my setup...

SOLVED --
The mistake was my own...in writing this post and re-testing, I realized I had made a foolish mistake. I applied an access-list (which I forgot to include) to the "ip wccp web-cache redirect-list bypass_content_engine" in the global config of the router.
When I installed service 95 for spoofing, I automatically added the same access list to it as well.
This was not a good thing since the access list denied packets with a destination of our internal IP addresses from going through the content engine. This worked fine on the way *out* of the router. But as the now-spoofed packets returned, their destination was an inside IP address and they were pretty much discarded. Foolish Mistake!
Removing the ACL from the "ip wccp 95" statement in the global config fixed the issue and I am spoofing fine.
Sorry to waste time...

Live-Video and ACNS: Different documentation?

I had found two statements regarding live- video and ETV:
First in
http://www.cisco.com/en/US/partner/prod/collateral/video/ps9339/ps7063/data_sheet_c78-504500.html
"... Cisco ACNS provides both live unicast and multicast streaming services and on-demand access in which digital media files are cached locally for retrieval and viewed over the WAN at LAN speeds (Figure 3)."
And the second statement in
"Cisco Digital Media System 5.1 Design
Guide for Enterprise Medianet":
"... For Digital Signage and Enterprise TV live content, multicast is required as the transport. Cisco ACNS
does not support unicast to multicast conversion for the delivery method used by Digital Signage and
Enterprise TV. For this reason, Cisco ACNS does not provide any benefit for live content...."
Is there an difference or is this an failure?

I think the first statement should read:"ACNS does support unicast and multicast splitting for live broadcasts TO THE DESKTOP and with Windows Media streaming"
The second statements hints to HighDefinition streaming which is mostly compressed with H.264 MPEG4, and i don't think ACNS is able to split this (or convert unicast -> multicast)

ACNS nsc link issue

My windows player is returned with a link something like this http://server_ip/stream.nsc?item=12345&enviro=67890&type=.wmv
However when I try http://server_ip/stream.nsc it works fine.
My question is, why does the ACNS system fail when the link has parameters?
Thanks in advance.

Adrian-
I assume you are talking about a live channel setp on a CE by a CDM? Exactly who is adding the parameters to the url?
Normally, when you setup a channel, each CE that will be sending out a stream by itself. The reference NSC file to access the multicast parameters would be an http link with an FQDN of the CE itself, and a nsc file with the name of the video/channel. There would not generally be parameters passed into it.

Chris

[SOLVED] Cannot 'seek' in stream using mplayer

Hi,
When I try to play a video of a television broadcasting of the Netherlands Public Broadcasting using Uitzendinggemist.nl, I get an mplayer box playing the video, e.g. within this window (I hope it's available outside of my country).
In Windows Media Player (running in my favourite operating system) I can use the 'seek' functionality to fast forward a stream by moving the scroller (e.g., after playing got stuck, which happens every now and then, especially during interaction with the user interface; the screen just goes black, mplayer tries to connect to the server and then displays 'Idle'). In mplayer, I can't.
After retrieving the URL of the video stream I started mplayer from the command line to get more information. I also tried to seek by using arrow forward and backward:

That's indeed the same issue, thanks. In short, as these streams are served using the mms: protocol, I cannot use wget to get the file, so I used the second option to save the stream to my harddisk:
mplayer -dumpstream -dumpfile filename.wmv mms://example.com/nameofstream

WMT license for CEs

We are planning to implement Windows Media Services 9 as broadcast server to stream live powerpoint presentations.
We have a lot of CEs in our Intranet (for e-learning) and we would like to activate the WMT license to use these CEs as cache proxy for live streaming. I wasn't able to understend where i can get a license key to activate the CE's WMT server. Windows Media Services are part of Windows 2003 Server, does this mean that i need a Microsoft Windows 2003 Standard Edition license key to activate the CE WMT server?
Thank You very much for Your help.

Stream 8 tablet location does not work on T-mobile broadband

On my HP Stream 8 tablet, location works fine with GPS only (GNSS on; Mobile Broadband, Wi-Fi, and Bluetooth off).
However, if I turn on Mobile Broadband and connect to T-Mobile and turn off GNSS (or GNSS on inside where there is no GPS signal) and keep Wi-Fi and Bluetooth off, the location gives very odd results. Last week the map showed Phoenix as my location (I am actually located in San Francisco). This week, it gives Brentwood or Clayton, CA, both more than 30 miles away.
HP tech support said call T-Mobile. T-Mobile said they had occasionally seen equally odd locations.
I went to a nearby T-Mobile store. They had a Samsung Galaxy Tab 4 which always gave a correct location, within 100 feet using T-Mobile alone. Manually moving the map to a different location in an attempt to confuse it and turning it on and off, it would still find the correct location. No surprise there, my three year old Virgin Mobile LG android cell phone does just as good a job at finding locations.
(The T-mobile store also had an iPad Mini 3 that I was able to confuse. On T-Mobile alone and clicking on My Location in maps, it produced a grid that was blank except for a line saying that it was unable to find a location, no info or link to what to do next. The T-Mobile store did not have a Stream 8. The Microsoft Store has a Stream 8 but it is not connected to Mobile Broadband.)
Does anyone else have this problem? Is my unit defective? There are times that a GPS signal is unavailable and a T-mobile broadband signal is available, and it seems that this unit should be able to find a location at least as well as my cell phone.
Thanks.

I see the same basic results, wifi=off, bluetooth=off, gnss=off, t-mobile=on. Open win8.1 map-app shows my location in LA south of the 101/110 junction. I'm in SF Bay area near San Jose about 400 miles away. Turn on wifi and map-app shows me at my real address. With t-moile only, opened win8.1 IE, went to www.bing.com/maps location also shows LA.
My only t-mobile account is the stream8 free 200mb/month data plan, don't think they have my real address anywhere. My t-mobile "phone" number is 720 area code in the Denver area. No idea why middle of LA is the t-mobile location. Must be a "feature, not a bug".
