Media Server :: Determine What Limitations SSAS Has That The C++ Plug-in Architecture Can Rectify?
Dec 9, 2010
I am currently trying to determine what limitations SSAS has that the C++ plug-in architecture can rectify.
Currently I have determined that C++ plug-ins can provide the following benefits: Quality of service increase/decrease based on client info via reserving a set of core processes for premium clients, then have a set of core processes for everyone else. Additional layer of security in the Authorization plug-in
I have not been able to find very many features that the C++ plug-in can provide that you can not provide with some code in the SSAS. So I guess I am just looking for a comparison table of advantages/disadvantages between the C++ and SSAS. How can I exploit the C++ plug-in architecture to do amazing things that the SSAS can not?
Is there some FMS-specific reason why a sendAndLoad function in SSAS couldn't connect to a site on an IP address? Are there any configurations that would need to be set to allow/deny this type of connection? We have a server instance that can only connect to sites hosted on fully qualified domains.
I am using FMS 4.5 and have a simple application which I want to use to send two strings to a php file. But I get a compilation error whenever I try to assign any value to these objects:
Here is main.asc:
<code> var variables = new LoadVars(); variables.username = "uname"; variables.send(http://url.abc.com/test.php,POST) </code>
I can't compile with the second line. FMS just says: Sending error message: Compilation error
Is there anyway to utilise the bandwidth of the flash media server from the server side in such a way so that the streaming will happen from the flash media server to the user based on the user internet connection speed. So users with low bandwidth will receive less streaming data in their buffer and users with high bandwidth will receive more streaming data into their buffer from the server.
Is there any way to access a Flash Media Server server-side script through a C++ plugin? I know you can call server-side functions, but I want to use the plugin to do image processing, so I need to get bitmap data from the client to the plugin. I've been poring over the documentation and the forums and there doesn't seem to be any way for the plugin to communcate with the server other than to read Event properties. If this is the only way for the plugin to recieve data from the server, is there any way to override an event property to send custom data?
In <FMS plug-in developer guide> we can see "You can query your organization's database of users and passwords to determine which connection requests should be allowed. Once the plug-in accepts the connection, you can update the database with a record of the
I purchased FMS 3.5 Streaming Educational when I was in school, but now that I have left I want to use it for commercial uses. Can I still use the same licence? If not, is it possible to upgrade?
I do understand the differance between ssas and as3. Not all, but all most everything I see written in SSAS can be writen into a external AS3 file. This leads me to quite a few questions I'm hoping you kind people can shed some light on for me.
1) What is the advantage of writing a SSAS file over an external AS3 file?
2) Can I write an .asc file in AS3 or do I have to use AS1? Please understand I'm using tuts from fmsguru.com and the books "Learning Flash Media Server" (pdf) and "Programming Flash Communication Server". I'm not a javascript programmer so nothing I do in AS1 seems to make any sence while everything I do in AS3 does. It may not seem like it to you people that are programmers, but to those of us that aren't, AS1 and AS3 are miles apart.
3) kind of off topic, but a security question. I'm not a "hacker" and don't like the jerks that are. My question is on external AS / SSAS files and swf files. When my fla is compiled into a swf does my external AS files remain external? I assume they do, but then what is the threat of the swf being decompiled? In most projects I would do I could care less if somebody had access to my fla as long as they don't have my actionscript files.
I don't know. Maybe on questions one and two I'm getting confused becasue I'm using out dated material. Again I assume that even though fms was built off of the javascript engine it should be able to read and execute my AS3 file. Other wise what was the point of the evolution of actionscript into a fully functional programming language?
I am connecting FMS over RTMP from a firewalled network where RTMP is blocked.Connecting to my FMS server from there takes (a too long) one minute before the Flash client switches from RTMP to encapsulated RTMP into HTTP.Is there any way to by pass this delay or is it a plug-in inner behavior that cannot be short-cut ?
We have an old Flash application that has worked fine for years, but intermittently fails on latest versions of Firefox. Using the same version of the Flash Player, the application runs fine in Internet Explorer. Recompiling the product is risky, and I'm trying to fully understand the problem before resorting to that. I'd like to be able to point to a known browser or player bug, but I can't really say where the problem is yet.I've gather the following information using Charles Proxy:The Flash application gets a list of files it needs to load. It requests a file then waits until the Flash Plug-in dispatches an Event.COMPLETE before requesting the next file. During this process I can see the HTTP requests and server responses. When the application "hangs", Charles Proxy reports that the response actually completed; however, Firefox's status bar shows "Transferring ..."
Sometimes for an extended period, I can't recreate the problem at all. At other times, the hang-up happens over and over again.Finally, if we switch to using https instead of http, the problem NEVER happens. Because Charles Proxy shows Status Complete while Firefox shows that a Transfer is still occurring, I speculate that the problem is actually in Firefox. I believe that Firefox is failing to recognize when the file actually finished loading, and therefore it fails to tell the Flash Player. The end result is that our code gets no Event.COMPLETE from the player and cannot continue requesting files.
As stated in the title, I want to know how to determine if my server/host has native bandwidth detection. I have FMIS 3.5 installed on my Linux server. Is this a setting in FMIS or is this something I have to call my host to find out?
I must rejected all users outside Denmark from our live streaming (c-ip) and this is done in an access plug-insBut now I need to open up one of the streams, but I can't get the streaming name in the access-plug-ins only in the Auth-plug-ins.I cant use x-page-url or s-uri I need pStreamName. in access-plug-in like thissetStringField(m_pAev, IFmsAuthEvent::F_STREAM_NAME, pStreamName);but I cant get it inside the access-plug-in
I know there is a way to determine how many users can connect or "join"( in a manner of speach) per second, and how to set a maximum number of users in the queue to join, this does not mean though, that the server will reject all or any petitions after a certain number of players are connected or viewing a stream, which is what we need to do. anyone know if its possible to do this and how?
in other words,we need to set a limit on how many users can be watching a stream at any given time, be it by stream or by server, it matters little, we just need to get it set..

Can Adobe Flash Media Streaming Server 3.5 run on AMD Athlon Dual Sock Quad Core?I just requested a Dell server to be added to our farm to run as a Media Server and to my surprise, while reading the requirements for FMS it states the following: 3.2GHz Intel® Pentium® 4 processor (dual Intel Xeon® or faster recommended)
I'm trying to troubleshoot a Flash Media Server working with a little video playback application I wrote a few years ago that has suddenly stopped working.I'm using CS3/Actionscript 3.My app uses the FLVPlayback Component, and was working well last time I checked. I recevied a report that the videos stopped working, and have been looking into it.I figured I'd add a bunch of event listeners to the FLVPlayback's ncMgr.netConnection so I could get debug info on things like io errors, net status, etc.The problem I'm running into is that the netConnection is null when I set it to anything on my Flash Media Server, and adding any event listeners to this netConnection throws errors.Here's what I've tried so far:
Playback of a local FLV file works fine.In the FLVPlayback documentation, I found an example and stole the URL of the stream they were using in the example, and that works fine, although it is an HTTP protocol stream rather than RTMP.Any attempt to access FLV files on my Media Server, which has worked fine in the past, basically cause the FLVPlayback object to sit and hang in "buffering" mode and never progresses beyond this point.The netConnection object in this case is null.Here's my code:[code]........
Again the purpose of this is to troubleshoot the video streaming from the Flash Media Server, and it seems like there is no netconnection to the server being created.Does this mean that the server is not working, or is there a problem with the way I'm trying to access the content on the server?This was all working fine before, and I have set up the server-side application .ASC files and such to allow things to work fine on the server end.
I'm trying to make a software which sends video and audio data to a flash media server by using RTMP protocol. Currently, my program can communicate with a flash media server correctly. RTMP specifications does not describe about the raw data in video/audio messages, so I muxed raw H.264 and AAC data into video/audio messages and sent to the server. The server seems to accept them, but a video player cannot playback the stream sending from the server. The player just says "Loading..." For a test purpose, I sniffed the network packets between Wirecast and the flash media server and ripped off only video and audio data. Then, I muxed those data into video/audio message and sent to the flash media server. In this case, the video player connected to the server can playback the stream correctly.
I checked the stream sent from Wirecast, the stream seems not to be H.264 raw data because those data are not started from 0x17 instead of H.264 start code. With those situation, I am wondering what kind of container format I should use for H.264/AAC data to the flash media server.
I have to a problem using the Flash Media Interactive Server Feature Explorer. I want use the sample: RecordStream. I can see the instance "RecordStream" in console FMS 3.5. and show me the video in app AIR, but does not save the .FLV in my server.
I have Flash Media Streaming Server 3.5 (not Interactive) running on RHEL5.5 x86_64 Linux.All is working well, however how do I prevent unauthorized access to connecting to the live stream and streaming content?How can I setup the server to require a user and password to stream live media to the server?I am new to this product and I have been reading some documentation but I have not found a clear cut answer on how to force a username and password to connect to the server to stream live content only.I am using the Adobe FMS Apache install, what files need changing?[code]I want to lock down a person from connecting to the server on the public internet and starting a live stream?Can this be done with a user name and password?
We purchased FMIS and we are encoding large 15+ hour MP4 recordings using flash media encoder. When opening these large files for playback, which have not been opened recently the player displays the loading indicator for up to 4 minutes! Once it has apparently been cached on the server it opens immediately from any browser even after clearing local browser cache. So a few questions for the experts
1. Why is it taking so long to load the file. Is it because the MP4 metadata is in the wrong format and the file is so huge? I read somewhere that Media Encoder records with incorrect MP4 metadata is that still the case?
2. Once its cached on the server, exactly how much of it is cached. Some of these files are larger than 500mb.
3. What fms settings do you suggest I change. FMIS is running on windows server R2 64 bit, but FMIS itself is 32 bit. We have not upgraded to the 64 bit version. We have 8GB of ram. Is it OK to set FMS cache to 3GB. And would that only have enough room for 3-4 large files, because we have hundreds of them.
I am using flash media server 4.5 for video streaming and genrate log files. In log file i have found the user publish point name in "x-sname" filed but this filed contains blank values in many events.This fileds contains value only in "PUBLISH,UN_PUBLISH,RECORD and PUBLISH_CONTONUE" event and other then these 4 events all events are not user related event.?I like to fetch the user bandwidth detials using these log files which user used how many bandwidth.I also like to know I can see serval files on flash log folder name "access.00.log,access001.log and admin.00.log,admin.001.log" Any one please explain what is the name convation for this filed how can i identifiy which files contains information for which date.?
I'm building a video conferencing applicaition for a portal. But now when considering which version of flash media server to buy, I run into some problem. So can anyone helps me about comparing this two versions: Flash Media Streaming Server and Flash Media Interactive server, like if I use Flash Media Streaming Server, some function like NetStream.pause() may not work or something like that? I'm not sure if this is a foolish question but please let me know.
I'm running Flash Media Streaming Server and have only been serving VOD up until now. I had my network administrator open up port 1935 to the outside world during the setup process and now I can't remember if that was actually required for streaming VOD to clients. Most documentation I've read says that this port should be open, but I seem to recall reading something at one point that suggested it wasn't necessary.
I've just started messing around with publishing live streams using Flash Media Live Encoder to the Flash Media Streaming Server. I have that working without issue but was surprised to find that no authentication is required before a client running the live encoder can publish a stream to the Flash Media Streaming Server. An authentication module is available however it only works with Flash Media Interactive Server and Flash Media Development Server.
If I leave port 1935 open to the outside world, there would be nothing to stop anybody anywhere from streaming video via my server. Anyone else running a default install of Flash Media Streaming Server and with port 1935 open to the outside should see that this is true of their setup as well. I'm wondering if I can safely close port 1935 without limiting the functionality of the server or if there's some way I can require authentication prior to publishing a live stream even though I'm not on the four-and-a-half-times-more-expensive edition of the product.
