Media Server :: JavaScript Engine: How Many Properties Is Too Many For An Object
May 6, 2010
I know the engine is derived from Mozilla SpiderMonkey. I am using an object which properties are IP addresses, i mean literally, as in: object["123.456.789.012"] The object is a map of banned clients. The number of properties approaches several hundreds. I wonder if this is a strain on the engine in any way? The reason I use this is because property lookup is just about the fastest thing you can do, as opposed to say an array with indexes and ip addresses as values, which would be an O(n) operation when doing lookup.
My FMS client is calling a function (simplified) which gets the offset time in milliseconds of an flv file.According to the docs for creationTime, it should return a Date object containing the time the file was created.I cannot access any properties of the date object in the server script.
Client.prototype.listFiles = function( folderName ) { var testFile = new File('/streams/folder/fileName.flv'); trace("creationTime: " + testFile.creationTime);
I'm getting this error with one chat application. According to
[URL]
..I should "Check the JavaScript runtime size for this application in the configuration file". By default it was set to 1024. Any attempt to increase it causes FMS not to start again. This problem just came out of the blue. This same chat app has been in operation with no trouble for about 10 months. I restart the server machine on which it resides before each new chat session.
Currently we have updated to FMS4.5 and doing some evaluation on HDS. We published our RTMP streams to the livepkgr application and successfully setup and playback HDS. However, we found that a we can't access some onMetaData Properties during playback. Our player use onMetaData - "videodatarate" and "audiodatarate" properties. We are trying to migrate it to playback HDS, however, we don't seems to be able to get back the two fields?
Here is what I want to do: Take an object that has a bunch of properties set and possibly holds other objects in it, and serialize it or somehow save it to a file using the File class. Reversing the process is also necessary. I know about SharedObject, but I do not get the ability to dynamically change the save/load location as in the File class. Is this possible with FMS, and if so, what is the procedure? If it is not possible, then what options do I have to achieve the same goals? I have read the SSLR and searched for a solution but do not seem to see any means to do this.
i'm attempting to cast an object's property as an actual property of another object. here's my object variable: var propObj:Object = {prop:"width", width:50}; now i want to assign the property of a sprite using that object's properties. var sp:Sprite = new Sprite(); sp.(propObj.prop as Sprite.property) = propObj.width; now, i'm not even going to try that because i know the compiler will explode all up in my face. but you should be able to see what i'm trying to do. why i'm trying to do it is because i'm reading in an XML file with an undetermined list of usable properties for specific objects. so instead of writing something like a huge switch statement to evaluate whether the XML file has a value for that specific property, i'm trying to assign properties dynamically based on what's available in the XML file. if what i'm trying to do is possible, what's the best way to do it?
I'm trying to get the metaData as usual with NetStream object from FMS but in RTMFP protocol but doesn't work.However, with RTMP my code (which is coming from onMetaData example in livedocs)it works.
Is it need any special metchod/properties to get the metadata with rtmfp ?
My question is regarding the use of RTMP files (delivered via a Flash Media Server) and Papervision; specifically using an RTMP stream as a texture on a Papervision object. I've already developed a number of successful methods for applying progressive flv/f4v files to Papervision objects. The RTMP streams, however, have presented a number of obstacles.
I will bypass the myriad of research I've done looking into this issue and say that others have inquired about this as well - but from what I can tell, no solid answer or solution has been found - especially under Flash Player 10. So, here's what we have so far:
1. A Flash Media Server running on a University server.
If I'm streaming live video and chatting in an FMS app, should each component have its own instance of NetConnection or should they share one? Was thinking perhaps the quality of the live video stream would be hurt in a sharing situation but am not sure the architecture works like that.
From a development standpoint, I'd like to make one NetConnection instance in my main application file and connect with it. Then, when successfully connected, I'd like to pass that connection into any custom components that need it.
It's a bit vague - the whole thing with AMF. On one hand we have a client capable of serializing and sending everything from integers to XML documents and ByteArray streams, but on the other hand we have the FMS with a JavaScript host. Where is the bridge? :-) I mean how does one work with the objects, in particular, a ByteArray, received through the [generic] wire? It's easy with numbers and strings, but no word on more complex objects.
I'm trying to append a live stream to an existing file, but I cant figure out how to open the existing file and then append the live stream. This is server side as well.I know I need to open the existing file using stream = stream.get("file"). but I don't understand how to associate stream with the live stream coming in.
I made a flash effect for my friend's site and he won't let me get the flash back after a fight. I can see the effect on the homepage of his website. Is there any way I can get the flash to an fla file on my computer? Is there any way I can find the swf file on his websites system and convert it to an fla?
One strange thing happened at application, connection to the fms server takes few milliseconds but shared object takes few second (more then 20) to connect.
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 need to move two figures on the stage with shared object like the "Tutorial shared Object ball" on the adobe website but with more than one figure. All the client must see the figures moving. The figure are a circle (Cerchio) and a square (Quadrato). This is the script:
I'm trying to make text chat application using shared object. I'm using api Shared.getRemote("so",m_nc,true); to make the data persistent. It makes the file with extension fso. I want to save the chat history in notepad for further reference, and also load that data as per requirement.
i am trying to develop a multiplayer game using the flash media server. Currently i can get multiple users to control one shared object but i need to have 2 users controlling seperate shared objects on the same stage.
