Media Server :: 3.5 Buffering Too Much
Jul 14, 2009
i setup the development versionof fms 3.5 server on windows 2003 server and it worked great in my tests.so we bought the server and are putting it in production now.the only problem is i never "tested" large FLV files.now if i put a large 50+megabytes flv file in the server it constantly buffers on the client.Is there a setting that defines the buffer size to increase the amount of buffer data that gets sent to the client?if i use a small flv file it works flawlessly but for large files it says "buffering" every 2-5seconds on the client.the client is just opening the test page that comes with the server the server has 3000mb/s to the internet and the client has a 20mb/s connection so i don't think bandwidth is an issue...

I am running into some streaming bugs and am wondering if anyone else has come across them. Very grateful in advance for any help as I've been banging my head against this for a week now.
First of all, I'm finding that no matter what value I set for a NetStream's bufferTime property, the NetStream will not begin actually playing until the bufferLength property is over 2 seconds. This is not what Flash documentation says (that the default value of bufferLength is .1 seconds). Could this issue a function of the FMS configuration with my RTMP hosting account? Is it something I can resolve with my asc file?
Also: In my Actionscript 3 app, I need to pre-buffer a number of video streams so that any one of them can be triggered immediately later in the program. I do this by building an array of NetStreams (within a single NetConnection), then playing each of the streams I need to pre-buffer and immediately pausing each too. This is successfully causing them to buffer in the background, so that they're ready for immediate play when I need them. When I do this with just one NetStream, it works fine. But with more, the streams are behaving unpredictably. They are successfully buffering, but when I need to actually play them and I go to unpause them (Netstream.resume), the NetStreams are generally NOT playing back correctly. Their behavior is not consistent, and they mostly play with no video, or no audio OR video. The one exception is the FIRST NetStream that I started pre-buffering, which is the only one that's consistently playing back fine with its audio and video. Again, if I unpause any of the other NetStreams, they play back with just audio, or not at all.

When my streaming videos start they will buffer and begin to play as normal. However, as soon as the vid starts buffering again a problem arises. Basically what is happening is that Flash is buffering the video to a certain point, but instead of resuming playback from the point where the vid paused it now jumps instantly to the end of the newly buffered area without playing the vid portion in between. Which essentially means that it skips merrily through the video and never stops buffering. That said i'd prefer to get to the root of the prob, particularly if this is a codec/keyframe issue, since i could then re-export the vids appropriately.

I have downloaded and installed the Flash Media Server (FMS) trial version. Just purchased the software today and waiting for the activation serial number. I created a video gallery - [URL]. My goal is for these videos to stream just like vimeo. I am only using HD 1280 x 720 video. All videos are between 25 to 125 MB in size, originally .mov files converted to .flv using FFMPEG. Videos are between 30 seconds to 58 seconds in length.
I am using ColdFusion to upload and organize my videos and I have configured FMS to work with CF. The Issue is that these videos buffer the same way they did when I didn't have FMS installed. Press play, the video buffers, the video plays, then stops to buffer again. Stop and Buffer, Stop and Buffer. I can understand if there is buffering at the start of the video but not throughout. When I start the video over from the start, it has to buffer all over again!

I'm using the FLVPlayback to load streaming videos from a FMS. The bug that I'm running into is with the buffering state. Several times the video will enter a buffering state that never ends. The last video event that's fired in this scenario is the BUFFERING_STATE_ENTERED. But if I seek the video on the seekbar, it's playing away.

I am developing a video player that is almost done, but there is a problem in Bufferbar
I am using a flvplayback for video playing when I use http path for video it show bufferbar working perfectly like below:
Code:
_flvPlayback.source = "http://flash.projectstatus.in/fmsvid/sample.flv";
If I use rtmp path from the fms the bufferbar does not work it shows already full like below:
Code:
_flvPlayback.source = "rtmp://75.126.73.138/vod/flv:sample.flv";
In both case video playing perfectly. Only problem regarding buffering bar.

I'm trying to determine an initial value for NetStream.bufferTime based on the client's calculated bandwidth and the video's bitrate.As far as I can tell you can't do this, because you must have an initial buffer set BEFORE you call NetStream.play() (or use the default 2 seconds) and FMS does not call NetStream.onMetaData, where one would normally find the videodatarate, until after NetStream.play() is called.Even if you modify NetStream.bufferTime during the onMetaData call back it doesn't effect when the video starts playing or when the NetStatus event registers "NetStatus.Buffer.Full".
How do I find the Video Data Rate BEFORE I call NetStream.play?How do how do I reset the initial bufferTime before acctual play back begins and the NetStatus event fires with "NetStatus.Buffer.Full"

I am streaming a playlist of multiple mp4 video files with flash 9 and FMS 3 and have been experiencing strange netStream.time values when the buffering is set for an extra long time on slow connections. When I have my buffer set to something like 60 seconds I'll start experiancing this problem:
the NetStream.time value will return 0 on progress events while buffering, but the moment the buffer is full, instead of reading 0,1,2 +++ it jumps to a really high value, in this case 53.5 seconds, and sticks there until the video (which seems to play correctly from the beginning) catches up to that time and then the netStream.time starts incrementing as it should.
Another relevant fact is that the time the netStream.time gets stuck to always corresponds to the end/begining point between two streams in the playlist. For whatever reason this usually seems to be the third video in the playlist. If the connection is relatively fast and the buffer is set to a smaller value,

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.

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.

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.

The only clear difference between them is the price.I can afford baying the Media Streaming Server bat not the Media Interactive Server and i need to decide before i am turning to other very less quality java based solutions.

We will only use the servers for Live streaming and VoDs, so far no plan for any complex applications to be deployed on the servers yet. As
far as I understand, the bottleneck of streaming servers are with network connection rather than CPU or resources (servers are only support up to 4GB of RAM anyway).

I want to record a stream which is published with Flash Live Encoder to FMS 3.5, but split the recording in files with predefined length. For example if a stream 'webcam' is published I want to record it in chunks of 10 minutes: 'webcam1.flv', 'webcam2.flv' ... From what I can tell there's no facility to work with timers. The only solution I could think of was using stream.record() with a time limit parameter but that seems like a hack because it triggerstStream.Record.DiskQuotaExceeded on the stream when the recordin should stop and start recording another chunk. Has anyone done something similar?
