Media Server :: Playback When Using Stream.play("mp3:file") - Bitrate Conversion
May 16, 2011
I'm trying to setup a server-side playlist for playing back mp3 files, though I stumble into a weird FMS behaviour. I'm using latest FMS 4.0.2 Here is how I try to publish the stream (Server-side ActionScript):
[CODE]....
On the client side, I try to play it using NetStream.play("boo"). Though, the sound quality I get is really weird. The sound goes slower and faster and stops for a split of a second. It may play properly for a couple of seconds, but that's all. Sounds like a decoder problem to me, or a bitrate conversion problem. When I play the stream with NetStream.play("mp3:rhcp") the playback goes smoothly. I've tried several mp3 files with different bitrates, but they all have the same problem.

I don't think there is much to add to the subject. It is a bug, anyhow. Let's say I am playing content from publisher which is displayed in a video. I then close the stream, and issue a play call for content B on this same stream object. If publisher B is slow enough (no new data arrives for a short while), I manage to catch a glimpse of OLD UNRELATED content from publisher A! Why is this, and is there anything I can do about it? By the way Video.clear is broken in Flash Player 10, and that's public knowledge. However, I am not sure the clear method alleviates the problem. Even if you clear the video, the stale data appears afterwards anyway.

Q1. I have 2 web servers, 1 FMS server, 1 File Server. Files when uploaded, will be stored in File Server. I need to play the file from client system, please let what configurations shall i make so that the request will be sent tot FMS from Client and From FMS to File Server and back to FMS and then to client as a stream. scenario: I want to play a video. Request will go sent from client to FMS Server, FMS server will fetch the file from File Server and Stream it to the client. Q2. In Flash PLayer, I need to play all types of videos including the videos which will require conversion to .FLV. I have to convert the vedio at the time of upload, Please let me know few conversion APIs which i will use in my system.

I have FMIS 3.5.I've installed it with pretty much all the default values.I haven't changed any of the settings in either the LIVE or the VOD applications.Dynamic Bitrate Switching is working well for VOD, but not working at all for LIVE streams.Doing a regular bandwidth detection on both the LIVE and the VOD applications give similar, high bandwidth results. However, the LIVE application NetStreamInfo.maxBytesPerSecond is showing a very low bandwidth capability of around maxBytesPerSecond = 19016, where as for the VOD its achieving around 637110.I can play a single LIVE stream of a high quality smoothly without any error.
I don't know if this is relevent but I'm getting some error messages occassionally in the log of the live application saying : Dropping application (live/_definst_) message. Clients not allowed to broadcast message.These messages aren't consistent, and don't coincide with trying to use bitrate switching.I have tried downloading the Adobe sample StreamSwitching. fla and it won't play the LIVE streams at all.Using the opensource Longtail Video player it just always defaults to the lowest stream.Here is an example: http:[url]....

I'm using the Niagara 4100 streaming appliance to encode a live multiple bitrate streams for an event. The problem is the Niagara encoder doesn't allow me to attach an event name to the stream url like - 'streamevent%i?adbe-live-event=liveevent', instead it only allows 'streamevent%i'. So in the end I get three seperate events with a stream for each event.
Like so:
Example:
/Events/streamevent1/MNMMNNMxxxxx.stream
/Events/streamevent2/MNMMNNMxxxxx.stream
/Events/streamevent3/MNMMNNMxxxxx.stream
AND
/Streams/streamevent1/files
/Streams/streamevent2/files
/Streams/streamevent3/files
Is it possible to make it work this way without using the 'adbe-live-event' parameter using the .f4m manifest file?

'URL missing from Media tag' on FMS4.5 HTTP Live Stream playback.I have spent a whole day trying in vain to publish f4m live http streams from FMLE using FMS 4.5, and almost everything I try results in the error .The F4M document contains errors URL missing from Media tag...in both Flash Media Playback and the fms videoPlayer app.Other people seem to have seen this and solved it, but I've found nothing that helps. I have tried to publish a single stream, and with multiple bitrates. For the latter, I followed the Adobe video tutorial as follows:

I'm publishing 3 streams from FMLE, using

I'm recording a stream from a webcam as an f4v file using FMS 3.5. The file is created in the live folder, and i can stream it back to the client no problem, however when I try to play the file in Adobe Media Player (or anything else) it won't play. I've used the f4v post processor which claims to run successfully, but with no joy.

I got a bunch of live stream from FMLE, say: "FMLE_channel1", "FMLE_channel2", "FMLE_channel3". And then on the server side, I created several corresponding republished stream called "channel1", "channel2", "channel3".
On periodical basis, we call Stream.get("channel1").play("FMLE_channel1", -1, 10, true) every 10 seconds. Similar things were done on the second channel & third channel.Soon after the above Stream.get("channel1").play() call, I should get the following events in sequence:info :NetStream.Unpublish.Successinfo :NetStream.Publish.Startinfo :NetStream.Play.Resetinfo :NetStream.Play.Start In the above case all are happy. Clients can view channel1, channel2, channel3 well.But then after a while, one of the three channels, in most case it would be channel1, will not be viewable.
With the server trace info, I found that after the Stream.get("channel1").play() call, only the following two events exists:
info :NetStream.Unpublish.Successinfo :NetStream.Publish.Starti.e. I was missing the play.reset and play.start event.I further checked and confirmed that the FMLE was publishing all three channels fine to the server. I was able to view the "FMLE_channel1" from flash clients, but not the republished "channel1". the version is FMS 3.5.0.

I have an *.flv file on a FMS. When I play it on the client side the video plays just fine, but when I call Stream.play(filename, 0, -1, false) on the server side the video turns out really choppy.I both cases I use NetConnection to connect to an rtmp and NetStream to play the stream, but in one case I connect to a stream and request the server to play my file on that stream. Apparently that doesn't work with files? It works just fine for live streams.

I use Flash Media Server 4 and Flash Media Live Encoder 3.2 for a strem rtmp.
I set FMS url to rtmp:localhost/livepkgr and I set stream name to :livestream.m3u8
I started FMS and I'd want to play my stream in a HTML5 video tag.
I have not changed FMS4 parameter, and I'd want to insert the src attribute in video tag.

I'm stuck trying to get a Stream.play() call on a recorded video file (.flv) to translate from origin to edge servers. Don't even know if it's possible. If I call Stream.play() on a server, and connect a viewer directly to that server, the viewer sees the stream play. If I call Stream.play() on an origin server and connect a viewer to edge servers the stream does not play.
Is it possible to configure in any way that the play() call would propagate to edge servers? According to FMS 3.5 docs on the Stream class, the following is the case:
"When you call Stream.play()on the server, the server becomes the publisher."
See [URL].
If that server becomes a publisher and lets say it was an origin server on a CDN, shouldn't the other machines in the configuration receive the published stream? Somehow when you publish a live stream to an origin server it makes its way to edge servers. Is this analogy not relevant to the scenario wherein you call Stream.play() on a recorded file?

I'm trying to get Flex Builder 3 to play a live video stream with Flash Media Server and Flash Live Media Encoder.
I'm able to stream pre-recrorded (vod) flvs in flex from flash media server.
I'm able to stream live video using Flash/FMS/Flas Live Media Encoder, but not with Flex.
This code streams pre-recorded Video on Demand flvs, but not live streams:
If I change source to "rtmp://localhost/live/livesream.flv, I get nothing.

I've noticed an issue while creating one way (A publish B play) stream through RTMFP. When I try to create connection between computers behind the same NAT (same IP) stream playing is not fired at all, but on the other hand the same code works on remote computers (different IPs).This issue arose after releasing final release of Flash Player, in a beta release everything works fine.We checked NAT settings and there are no differences for this cases.

i was modified the main.asc script in livepkgr, it used to call s.play(streamObj.name), which i assume this is the code it play the stream from FMLE to s.play("FileName") , which is a flv video file in my application. unfortunately when i start the FMLE stream to the FMS and watch the stream with the FMS Sample Video player, i was expecting to see the video content from the flv, but instead the camera footage in playing on the player.
i am very confusing now, i thought the s.play the only code to control what should be playing in application. or when FMLE is connected to server, the server must play the footage from FMLE by some hidden code, no matter what s.play wanna to play?

NetStream.play(streamName, -1); This seems to be working wrong.if I have recorded an flv on server using FMS and FMLE with only audio with name "myaudio" and then after if I try to play a live stream using NetStream.play("myaudio", -1) then it plays the recorded stream. I believe that documentation says that it should start a live stream instead of playing recorded stream as the second argument is -1. Is this a bug in NetStream.play method?

I'm having a very frustrating problem with FMS. A stream recorded on the server-side won't play until I restart the server.
The user flow I'm currently working with is:
1. record webcam stream
2. close the stream
3. call FMS function to post process the stream
4. FMS joins the recorded webcam stream with two pre-recorded videos and stores as a new stream
Then, knowing the new stream name, I'm trying to play it. However, I'm always seeing its last frame and it doesn't play. Surprisingly, restarting the server and re-connecting to it helps, then I can play the stream.
So I wonder if (server-side):
var stream = Stream.get("streamName");
stream.record();
stream.play(...);
stream.play(...);
stream.play(...);

I am publishing video content to FMS with my program to livepkgr application. After i start publishing the vidoe content, files like .bootstrap, .conrol, .f4f and .meta are gettign created inside the livepkgr folder's my stream folder. But when i try to playback via OSMF player, the player is throwing error 1009. This happens for some few minutes. After some 4-5 minutes, the player start playing the live video content properly (.f4f file size is not getting updated for those few 4-5 minutes)

is it possible to receive live stream at bitrate lower than that which video is being recorded with? How to accomplish that? I know that play2 from NetStream class allows to switch between recorded videos at different bitrates, but what about live content? I cannot simply set bandwidth to lower using FMS because i need to be sure that framerate won't be affected, and there are also other simultaneous streams playing .

we are using RTMP with Flowplayer with dynamic bitrate switching and I'm a bit confused on the bitrate (kbps) that is called out in the code in order to configure the bandwidth check. I presume that this is the target bitrate if encoding using ABR or constant. How about for the rest of us that are using CRF? My understanding is that CRF is the way to go now for H264 (don't want to hijack the thread to a CRF vs ABR discussion). If we are using CRF, can we guess on the target bitrate that is called out in the bwcheck plugin?

if I repeat this IIS topic, I couldn't find the answer to my problem any where on the internet. I installed FMS Dev 3.5 on Win 2003 Server with IIS 6.0 enabled. I don't have any issue with port 80 Listening, I used the IP address 192.168.0.21 for my web application (IIS) and 192.168.0.22 for FMS (I only have one network card and port 1935 is open under firewall). I can play the sample videos (RTMP, HTTP, and Dynamic Stream) using the Flash Media Start Screen (or from the location C: Program FilesAdobe Flash Media Server 3.5webrootindex.html) without any problem.
I then modified the IIS Default Website to look at the "webroot" folder (C: Program FilesAdobe Flash Media Server 3.5webroot). From IE, I can access the default web site by enter http://192.168.0.21/index.html. The website loads up correctly, and the RTMP video is playing perfectly. However, if I click Play Video (HTTP) or Dynamic Stream (tab), I receive "Connection Error. Please press Play to try again."

I am running a website similar to Ustream and Justin and i am using Linux dedicated server, that have FMS 3.5 Installed. On My site registered broadcasters can stream their live video.
I want to know how can i limit the broadcasters so that they cannot broadcast a live video more then 512bitrate in their encoder.
currently any broadcaster can broadcast a live channel at any bitrate he wants and that is consuming too much of my server's bandwidth.
