Media Server :: Backwards Timestamp FMS Server Error?
Aug 24, 2010
We have a very simple webcam recording/playback application we're using in a mission-critical user assessment application.Users are given the ability to record themselves using their webcam and microphone, then review their recording and submit it for graded review.The recording application appears multiple times per HTML page, and while we can record and play back video, we have large numbers of instances in our core.log of the following error
Server detected a backward timestamp from [####]to [####] in file: [filePath]
While these videos will play back with varying degrees of reliability, they will often "hang" for several seconds at the end of playback before sending the appropriate NetStream.Play.Stop and NetStream.Buffer.Empty events, and will sometimes hang indefinitely.Further, they report inaccurate runtime metadata, causing our playback indicator and progress/scrub bar to function erratically.In any case, the functionality and user experience of the recording tool is substantially degraded and must be fixed in order to successfully deploy this tool.
Disabling NTP services is not an option, and further does not appear to be the culprit, as these errors occur on a large number of recordings.As recordings need to be immediately available for self-review before submission, running flvcheck on each recording is also not an option.We have tried a variety of fixes, including waiting to unpublish until the buffer is empty,reconnecting after every recording, forcing FMS not to reuse connections, and using separate NetStream objects for recording and playback.Nothing has eliminated these errors.Adobe support referred us to Tier 2 support, and I am in the process of contacting them, but I'm looking to exhaust all my options before continuing.Is there any reliable solution to the backwards timestamp recording issue, or do we need to find a different media server application for our needs?
I posted a discussion earlier on a video stream not playing past a certain time. I ran FLVCheck on the video and it came back saying there is a backward timestamp in the video. I recompressed it from the uncompressed video (AVI) and I got the same error again in the exact same place.
The error has to be in the uncompressed file, but I don't know how to fix it. Recompressing obviously doesn't help. Anyone know how to fix a 'Backward timestamp'?
I have seen lots of different things about recording live streams (maybe too much, pieces everywhere but no one good source for the answers), but not what I am looking for...I want to setup recording of live streams on FMIS 3.5 where the file is named the stream name plus a timestamp (something like streamname-yyyymmddHHMMSS: myteststream-20090928101015).The people who use our site tend to start/stop several times (we are dealing with events that have breaks) and I want to be able to combine all the files with the same name into one big file on the server side afterwards using some utilities.I cannot find a tutorial that walks you through the different functions, the differences between them, and how recording is setup/works.
The company I work for installed FMS on a server running Centos for a customer who needed streaming media capabilities. It worked fine for 3 months until today the customer called us and informed us that their client program can no longer connect to the streaming media server. No one has done anything to the server to cause this to happen. When attempting to access the admin console to diagnose the program, the streaming server returned a 500 Internal Server Error. So I tried another page. Same result. Reboots of both the hardware server and the FMS have changed nothing.
I have a REGISTERED Flash media server version with update 1 and when i try to start it I have this error in the evnet log : "FMS has detected system time is going backwards;shutting down server" i try to reinstall it, the system clock is ok
Dear community, i am searching for 6 days for a solution but i couldnt find. I installed the trial version of Adobe Media Server 4.5. I am trying to host live stream and it is working without error. but when i activate protection (PHDS), server gives en error code: 20...
Here is the server log...
After i could take the Live HDS, i made these settings as described at [url]
im using FMS4 as origin server and connect to FVSS from CDN, whose FVSS version's FMS3.5. with this all, when it's played with flashplayer from CDN every each connect require just wrote sth in the server log file as below:
Mon 09:51:56 AM: Assert failed in .TCMsgHandler.cpp line 70Mon 09:51:56 AM: Assert failed in .TCMsgHandler.cpp line 70Mon 09:51:56 AM: Assert failed in .TCMsgHandler.cpp line 70Mon 09:51:56 AM: Connect : rtmp://live.mywebsite.com:1935/2011/monitor/
and due to these frequent errors the CDN Edge service would get shuted down. but after i changed the FMS4 into FMS3.5 with origin server everything just worked well.Now my question is, is that a bug with FMS4 or? and what can be done so far if we want to go on use FMS4?
Some users are unable to access any of our video content, getting a Server Not Found error.We have our FMS configured to use ports 1935, 433, 80. Our firewall is allowing RTMP traffic to each of these ports. Is there something more I can do from my end to make sure users can access our FMS?
I am trying to set up DVR streaming using FLME. I'm following this tutorial: http:[url]........I'm up to Step 2,
I put in the following information into the FLME: FMS URL: rtmp://222.222.222.222/dvrcast_origin Stream: mp4:sample.f4v
Then click 'Connect' , but I get an error "Failure to connect to primary server verify that your server URL and application name are valid and that your internet connection is working and retry". My server is a 32-bit windows 2007 VPS , with FMS running.I don't know if I set up the DVR Cast application correct. All I did was copy the dvrcast_origin into the installationdirectory/applications, then I started a new instance of dvrcast_origin with _definst_...Also, I am running the trial version of FMS, and DVR needs FMIS. Is there a way I can just run FMIS?
I try to establich the connection with asc file from applications/videochat $connection_string="rtmp://videochat/"; And I'm getting the result from media server Connecting to the video server...>>The client does not have permission to connect to the application, or the application expected different parameters from those that were passed.>>The connection was closed successfully
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.
One server - is streaming server with Flash Media Interactive Server 3.5that host the application with asc files in FMS application directory.Second server - is the IIS web server that host thehtml,aspx,swf etc.. files.So basically i heve swf file on one server that have to connect to live streaming via rtmp on different server with different ip address.I did not find any clear explanation on this crossdomain rmtp issue.ys only HTTP can use crossdomain.xml policy filebut not rmtp.So what policy security procedure need to be done in order to enableswf file hosted on one server to connect and show rmtp live cam broadcasting from another server?
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.
The instructions for installation only cover installation on "localhost". I'm wondering if I could use the development server for a small scale website depolyment with restricted traffic, from a commercial server, such as goDaddy?And if so, what''s the method? Do I download the package from Adobe to my local hard drive and install over the network, or copy the package to the server and install it online?
The $995.00 version is listed as not supporting server side playlists. Is it possible to implement internet TV station like functionality using that version? I would like to have a list of files to play out and have it so those connected are all viewing the same thing.
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 am developing application for recording the video in mp4 format with h.264 codec and I am able to record video in mp4 format with h.264 codec, but when I am compiling the Swf by "CTRL+Enter" at that time I am facing error "VerifyError: Error #1014: Class flash.media::H264VideoStreamSettings could not be found" and when I am publishing Swf by "ALT+Shift+F12" then I am not facing any error,what step I need to do for removing the error.
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.
