Media Server :: NetStream.Buffer.Flush When The Video Is Paused?
Dec 26, 2010
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've made a custom video player in as3. Everything works, but once a video has loaded and played through completely, if the user replays the video it continuously fires the NetStream.Buffer.Flush event until the video stops playing again (by either ending or by the user hitting pause). It doesn't seem to effect anything negatively, but I would rather not have an event continuously firing in the background like that. I can't find any documentation of this happening online anywhere. Is this normal behavior for a NetStream that has fully loaded?
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.
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 just made it clear of the differences between the progressive video and streaming video *^_^* But I do need a feature of allowing buffering the video when it's paused, which I cannot find how to do it directly... I followed an article ( url...) to manage the buffer strategy but it didn't solve my problem. My problem is: if the user has a very slow network condition, he/she might want to just pause the video manually, and wait it to be downloaded until it's 'pretty much', and he/she can watch it without interrupting.

I really expect the "buffer when paused" functionality, is it possible to do?
p.s. I'm using red5, not fms, although I haven't touched the difference part of them.

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'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.
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.

How to flush SharedObject in a separate thread? FMS is blocking the program during write, and to save more than 2,000SharedObject takes about 15 seconds.
I have a Net Stream object that I am using to stream video from an Amazon Flash Media Streaming service.The video makes a connection and plays fine but randomly it seems to just freeze and the only way to get it to work again is to re-establish the connection. I have tried to put other videos in that amazon bucket as well and they seem to play fine. this happens when it is in .FLV form and .mp4 format.
I have set the buffer time to be 5 seconds and i watch the output of the buffer to see the % of full it is. when the problem occurs the buffer 5 goes from 100 to 0 and then it throws a Buffer fail error (i'm using OVP framework).I have come to the conclusion that it is either a video encoding problem or perhaps there is a firewall issue that blocks the data from getting through.
I have a player set up to stream live tv channels. It works fine except when paused for more than 10 secs or so, it continues to stream but very jumpy, as if we press on advance/rewind button.
I'm making a small video players in AS3, and I've found that after calling NetStream.pause() or NetStream.togglePause(), no status messages are being fired any more.If I click the "pause" button while the video is buffering, I never get the Buffer.Full message.Here is some code:
_connection = new NetConnection(); _connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler); _connection.connect(null);[code].....
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'm using OSMF v.95 to handle my video playback. When my streaming videos finish, the following error is triggered:"NetStream.Play.StreamNotFound"I want to be able to re-play the videoor scrub back, but the stream is unusable after that error.I've tested against a few different streams - here is one:
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
