Media Server :: Increasing FMS Buffer Size To Display Video Smoothly
Feb 8, 2011
I need to increase my buffer size in FMS. My video is running from RTMP and I faces the problem to load. Video stalled between the running. So I need to increase buffer size for running video smoothly.
I have a block which I want to increase in size but instead of increasing it in one block movement, I want to make it move up smoothly, (its supposed to be water rising). This is what I have at the moment
ActionScript Code: Lock_Water.addEventListener(MouseEvent.CLICK, resizeLock_Water); var Lock_Water_ori_pos = true; var Narrow_Boat_inst_ori_pos = true; function resizeLock_Water(event:MouseEvent):void { if (Lock_Water_ori_pos == true){ [Code] .....
I am having an issue with sockets where the data I'm sending is getting truncated on the client side (Flash/Flex). The data that is sent by my server is full and in tact, but flash does not wait the appropriate amount of time before firing an event saying to read the data. This results in the data not getting fully read and (as such) I can't parse the object out of it after that. We are exploring the possibility of stripping the object into smaller chunks, but the idea is for it to be as lightweight as possible so we would much rather get it to work the way it's supposed to than patch in a temporary solution.I'm not entirely sure if referring to it as the receive 'buffer' is correct, as some computers are able to receive all of the data and others are having it truncated (which means the buffer is adequate but flash isn't waiting the appropriate amount of time to dispatch the event for whatever the reason).
I'v made an application with all the default codec and settings provided by adobe to publish live video using FMS. I've made two swfs one is for publishing live video and the other is for viewing the published stream (telecast). When I'm publishing the live video on My laptop using the default web Cam and mic attached to the Dell laptop then after 2- 3 minutes delay on the telecast side start increasing and it keep on increasing continuously .At the same time when I use my desktop PC by attaching external Web Cam and mic to publish, delay on my Telecast side is consistent ,it never increase. I found the problem is with the Laptop's mic. Can anybody please suggest me why it is happening, and is there any solution to it.
I have made a sample application for publishing video through FMS using as3.In that I had used the same code as given in the sample provided by the adobe,
m_nc = new NetConnection("rtmpt://localhost:1935/Test"); private function onNetStatus(event:NetStatusEvent):void { switch (event.info.code) case "NetConnection.Connect.
I just had a very bad user experience here: [URL] The Loading... text appears every 1 second. Is it possible to buffer all the video content before playing it? Or at least a portion of the video content when playback, and at the same time display the percentage of video content loaded?
I'm new to all this, so please forgive my lack of knowledge My purpose of this is to do high quality video conference. I've set up flash media server, and installed media encoder on another computer, input and output looks very much the same, but on the media player, it has about 1 second delay even on LAN,
is this because of the buffer of the flash player? how can i disable buffer completely?
I notice that, when I pause the video, the event "NetStream.Buffer.Flush" is triggered. And according to the language reference: "Data has finished streaming, and the remaining buffer will be emptied.", I have to re-buffer it, right? However, also according to the reference, it shouldn't stop buffering:Starting with Flash Player 9.0.115.0, Flash Player no longer clears the buffer when NetStream.pause() is called. This behavior is called "smart pause". Before Flash Player 9.0.115.0, Flash Player waited for the buffer to fill up before resuming playback, which often caused a delay.I'm using Flash Professional to do the debugging, and the traced version number is: MAC 10,0,22,91, and the streaming server is FMS4
I'm currently working on a webcam recorder to record high quality video. I had the recorder working before, but the video quality was quite poor. Instead I'm trying to use a client side buffer and then upload the buffer after recording has stopped. I thought after I unattached the video and audio from the NetStream that either a NetStream.Buffer.Empty or NetStream.Record.Stop event would be sent when the buffer was finished uploading.
What is actually happening after I start recording is two NetStream.Record.Stop events are being sent in a row, so recording never really happens. Also, on the server side I'm trying to save a user name and password into a variable, but I'm not sure how to go about doing that since the application script is just a bunch of callback functions.
Finding faults in my reasoning, or expanding the discussion further. We are benchmarking FMS 3.5.x for live dynamic streaming and we have run across an issue. When throttling the client from a high bandwidth (1500kbps) to a low bandwidth (325kbps) via a bandwidth shaper (a physical firewall) it takes a very long (real-) time for the client to see the new stream-quality.
During the investigation of this issue we have narrowed this down to:
1. when transition is requested from client, the client-side buffer is 1/2 i.e. 4-5seconds. 2. if transition is request on a client with unlimited bandwidth, it takes about 6 seconds for the server to process, find an acceptable switching position and send a "transition.complete" event. 3. on the throttled client however, this event takes much longer.
I've build a simple video chat application. The problem is that there is a delay of seconds between video display i.e. user1 video motion change displayed bit late at the user2 window. I'm using FMS 3.5 and FLEX.. IS THIS PROBLEM RELATED TO THE BANDWIDTH. My FMS bandwidth is 256kbps.
I am publishing the video over FMS and viewing it on other PC through display video. Now when I stop publishing the video, I am getting the last buffer as still image on the other PC(viewer). I want to know how we can delete that last buffer on viewr PC when publishing stops.
I have a service running off a FMS and I was wondering how I would get a stream to keep downloading the rest of the file even while streaming. For example, like YouTube downloads the entire video while you're watching it, much like Progressive Download does but I want that from my streaming server.Or even better than that, if I could buffer at least 20 seconds ahead of the current stream position. If I use NetStream.setBufferTime(20) - the stream doesn't play until at least 20 seconds has been buffered, but I want it so that it will play even though it hasn't buffered completely, but will keep buffering while streaming.
we are using FMS 2.0. I need to patch the buffer overlfow vulnerabilities. The doc that Abobe supplies with the patch/upgrade releases is confusing. The doc for the 2.0.1 recommends uninstalling 2.0 prior to the 2.0.1 installation. Upgrades 2.0.2 and up do not state this.. However, installing 2.0.5 specifically mentions patching v 2.0 vulerabilities, but does not mention uninstalling first OR that prior patches need be applied...And, finally version 2.0.2 - 2.0.5 do not mention is the patches are cumulative - are they?
We are experiences a phenomena that flash clients connecting to a live (pre recoreded)stream served from FMS (we use 3.5.2), have their buffer grow out of proportionit is alsoccompanied mostly with a complete video freeze, until the browser crashes.(you can expect a crash after having more then 4000 seconds of video buffer active in memory)The more we switch streams via a playlist,the more this seems to happen,Thus, streaming long video feeds keeps the system stable, but when injectingfeeds into a main stream and switching back increases the probability
I am developing a C++ program to connect FMS via RTMP, and then publish a live stream I can't use FMLE here because I need collect the H.264 NALU from somewhere and forward them to the FMS.I write a demo app, which parses H.264 encoded FLV file, and send the VideoTag in the FLV as RTMP Message content for publishing.Finally, I make it run and I can see some frames of video!But the problem is: The video does not play smoothly and it just updates some frames. Then I looked at the NetStream event and found that:Everytime when there is a NetStream.Buffer.Full event, the frame in the video is updated and display correctly But immediately there is another NetStream.Buffer.Empty event followed and the video is frozen.
I'm sure this has been asked and answered a million times, but searching for "application" "buffer" "cache" "live" and "hls" isn't giving me any answers, so let's get to it. After I end a live stream (which I do using FMLE 3.2 and FMS 4.5) and I then start a new live stream with the same application name, the HLS stream just loops the last 30 seconds of the old stream. To prevent this, after I end a stream, I have to go to applicationslivepkgstreams\_definst_ and delete the buffered data there. Only then can I start a new stream with the same name as the old stream. Now... that can't be normal, can it? Is there a switch somewhere I can set to tell FMS to cut it out and stop buffering old streams?
dvrcast is a live service.mp4: as the service record and I look over to the dvr sample player debug output messages while out NetStream.Buffer.Empty will stop.Screenshot is shown below. Is it possible to do without stopping the service?
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.
when i try to live stream with FMS! I can stream video with Flash media live encoder to the server but when i create the player to recieve the livestream from server,i can not recieve the live stream,can anyone give me a step by step tutorial of how to do it?
Flash media server 3.5 to stream live video to a webpage with flex GUI embedded in it.For this I have used Adobe flash media server start screen .I could able to stream video correctly.I want to know how long it could be do like this.ie suppose I have to stream like this for 3 or 6 months
