I herd about RED5, but unfortunately I can't find any examples for feeding it with external source. I know RTSP is in development, but I'm thinking about (named) pipes or something like this. There is is also project named xuggle that is as far as I understand ffmpeg wrapper for Java, but I herd they have also problems with live streaming.

I am in the market for a good (pro)camcorder to stream live university seminars. Currently I use a Canon Optura Xi with firewire output and use the miniDV tape for backup in case something interfers with the live stream. I want to get away from miniDV tape and find a video camera with SD/flash card recording. My dilemma, most new camcorders do not have firewire output for live recording. We do our live stream through the Adobe Media Encoder

View 1 RepliesI have some questions regarding 4.5 and deciding which version we must license (FMIS or FMS). Obviously there is a huge price difference and as this is within a local network we don't require encryption or multicast. Here is the scenerio we need to stream live DVR to mac, windows browser AND iPhone/iPad and devices running Android 2.2(Froyo)+. I need someone from Adobe to help us decide.
1. I see DVR is now listed as a feature in Flash media server page. Does that mean its no longer exclusive to Flash Media Interactive server. For both http streaming and RTMP?
2. Previously in order to stream live to Adobe dynamic streaming, Flash media interactive server was required because a live segmenter had to be used. Is this still the case? Or can we just launch adobe live media encoder (FLME) and stream to flash media server.3. Related to #2 can we switch between serving streams via RTMP or dynamic streaming without changing the format of the material on disk?4.I was at a webcast for 4.x and remember being told that the latency for http live dynamic streaming was 20 seconds because of the repackaging that had to take place. Is this still true? What is the latency for iOS playback from ingest to playback?5. For the iOS playback feature do the streams have to be in Adobe dynamic streaming format or can we just stream via FLME RTMP and trust it to do the right thing?6. Does the iOS playback support DVR?7. Does the Android plugin have good support for RTMP live streaming including DVR?

View 1 RepliesI'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.
Is it possible to live stream both RTMP and HLS with FMS 4.5?
I want flash users to have the least latency possible using RTMP, and iOS users use HLS.
Live streaming and a buffer on a NetStream do not mix. Why? The docs don't say you can't do this.The playback gets hosed. Buffer is supposed to fill to what you set it to before playing. Instead though, about half the time, the player starts playing right away and disregards the buffer time you've set. Then you get caught in short buffering and rebuffering cycles that degrades the playback experience.
Give it a shot yourself. Here is the simplest of live streaming video players. No frills. Just connect it to your live stream by changing the defaultURL string and stream name in the ns.play() statement.
Run it in Flex debug mode. It will check and print the ns.bufferLength property every second. The buffer is set to 20 secs currently. Last time I ran it, I never made it above 2 seconds in the buffer. Player started playing right away instead of buffering the full 20 secs first. Sometimes you get to the full 20 and sometimes not.

What's the best way to check whether there is video data (or not) in a live RTMP stream? For example, if a broadcast terminates, can I auto-detect that condition, to perform some sort of "thank you for watching" behavior?Also, how can I know if a visitor somehow gets disconnected from the Internet during the broadcast? (So I can notify the visitor of the problem, and give instruction.)
View 1 RepliesCurrently, we are streaming using RTMP, but I want to switch to HLS to allow iOS devices to stream our video. I do not want to encode two separate streams though because we are operating with limited bandwidth on mobile data cards. If I stream using the livepkgr, the delay to iOS devices is about 12 seconds which is OK. However, on desktop clients, we have live scoring integrated with our video, so we cannot have a delay that long. My question is, if I connect to the same stream in a Flash client for the desktop, will the delay still be that long? Or will it stream in real time to flash clients with the delay only for iOS devices using HLS? Also, am I correct in assuming that I can do this on 1 stream, or do I need to setup a separate stream for RTMP and HLS?
View 1 RepliesI am building a flash media player for an live audio stream. The server is set up to stream from a url that looks like so: [URL]. The instructions I have found say to first set the directory:
nc.connect("rtmp://ourwowzaserver.net:80/ourfiledirectory");
And then later play it:
nc.play(mp3:thefilename)
This works when we have discrete filenames on the server (thefilename), but the live stream is not a file - rtmp://ourwowzaserver.net:80/shoutcast. How in the heck do I get .play to play it?

I am in a requirement where I need to calculate the bandwidth usage of rtmp streaming. Is there any way I can calculate the number of total bytes I have download during the rtmp streaming?
View 2 RepliesI am trying to publish a video to an RTMP Server but it doesn't publish. It might be a pre-release bug. I am able to play a NetStream but not able to publish one. Is there a sandbox issue? I'm not sure. Because, the FMS RTMP Server will not let a client connect unless it has been downloaded from the same host as the server (something like a sandbox condition)
View 2 RepliesHow can I calculate the number of bytes download during RTMP streaming? So that I can keep track of bandwidth usage for particular user? I hope the question is simple enough to understand the requirements.

We are attempting to transcode some video to a format suitable for our Flash Streaming Server. In the past we have used Adobe Media Encoder (AME) CS4, but we are working with *.VOB files this time, and AME CS4 does not support them. We are attempting to use Handbrake now, as it has great support for h.264 and MP4 files. Unfortunately while the files play wonderfully on our local machines, they do not stream from the Flash streaming server over RTMP. The files come out of Handbrake with a *.m4v extension. Our old files out of AME CS4 are *.MP4's with h.264 and AAC audio. I can see no differences in video or audio codecs which leads me to believe it may be a container format problem. We are attempting to use Handbrake because it does an excellent job of batch encoding files and produces good quality files.
View 1 RepliesAt a certain point in the app flow, a m4v video is streamed from a remote location via rtmp. This works well, except for two little problems:
1. In very rare cases, the video starts playing, but you see no images and only hear the audio. Seems like this happens more often with Chrome, but that is only a guess.
2. In the first frame or so of the video, you hear a noise in the audio. It really is very short, but still a nuisance. This chirp is not there when viewing the same video with VLC or QuickTime player. It IS there when viewing with the Windows Media Player.
Are there any known problems with codecs and the flash as3 video streaming (via NetStream/NetConnection)? The video is composed by using the ffmpeg library (one mess of a library, I can tell you...) to bring together a live-rendered video (using a 3D Engine) and a pre-created *.wav (which does not have the chirp).
I'm trying to stream live video for the first time. I've installed FMIS 3.5 without Apache 2.2. I'm confused on the RTMP/HTTP protocol usage,I can only have port 80 opened on our FMIS 3.5 box.

I've freshly installed the FSM demo on a redhat linux box, and have everything working. From that start screen running on Local Host, I click the "Play video (HTTP)" and that video of a train shows up. Cool. But when I click the link above it ("Play Video (RTMP)") I get an error message: "Connection Error. press Play to try again." and no matter how many times I hit play, I get that same message. The Dynamic stream doesn't work either, and the Interactive sucessfully displays webcam feeds, but doesn't show the "Play Live Stream" button thing. Is there anything special you have to do to get the RTMP stuff working? Some special command or server you have to run?
Would firewalls intefere with things (I'm pretty sure there isn't one on the machine, but I'm flailing wildly here) or would permissions mess things up? I'm completely lost ^_^;; I guess I should also add that there doesn't seem to be any log files. I'm looking under the server install directory, and there isn't even a "log" folder. There isn't one under Apache, either. It confuses me. So far all I can find on the internet is instructions to look at the log files...but if they aren't there... Am I just looking in the wrong places, or are they just not being generated yet? I did a tcpdump with wireshark, and the web app IS pinging port 1935 (for RTMP), but the packets are failling the checksum and are refusing to be reassembled because of that. Is this making sense to ANYBODY?
I am developing an application in Flash that runs locally and it uses FMS 4.01, locally. I have been using adobe FMS 4.01 for months with no problem. Today I cannot connect to my server and I cannot even play the sample video on the Flash Media Server Start Screen. The sample video for the http plays after I changed the permissions for flash, but rtmp does not play. I have reinstalled the server; 3.5, 4.0 and 4.01, none of them will connect to rtmp. I receive this error on the flash media server start screen that says "the connection timed out".

Is it a FSM problem or Flash Player problem?
I have some .mov files want to stream to Flash media server by ffmpeg. i have already tried to stream a single .mov by FFMPEG command in terminal and it works, the FMS can display the thing i streaming in live.Now i want to stream multiple files as one source, i tried to use above command one by one, but it seems Flash media server stop the streaming when file1 is finished, then start the stream with file2.It makes the stream player stopped when file1 is finish, and i have to refresh the web page in order to continue on file2.i am calling the FFMPEG command by a C program in linux, i wonder is there any method that i can prevent the FMS stopped when i switch the file source in FFMPEG? or is that possible to let FFMPEG constantly deliver the stream by multiple files source without stopped when a file finish
View 2 RepliesUsually, flash streaming is done by capturing webcam video/audio and streaming using NetConnection and other objects to servers like FMS,Red5,Wowza etc.I haven't found any example on how to create your own stream of images and stream as a video to the server.I know it would be possible to convert the image to bytes and send via SharedObjects. Then decode on server and create a video file on the server (e.g. using ffmpeg), but I would rather do it in realtime on the client side if possible.
View 3 RepliesI've created a player for a client in the past using their LimeLight server to stream videos and not had an issue before, however for a new client using different LimeLight server, the videos seem to be ending 3-4 secs too early.
My traces on 3 vastly different videos I tested:
metadata duration = 32 // 32 secs long, ends at 27
Stop [27.350 seconds] = 4.65
metadata duration = 17 // 17 secs long, ends at 12
Stop [12.852 seconds] = 4.148
metadata duration = 258 // 258 secs long, ends at 255
Stop [255.861 seconds]
In the video players I check for NetStream.Play.Stop then put a 'reset' type function in there. This function however triggers too early due to this strange bug. Has anyone have seen this before?
private function netStatusHandler(event:NetStatusEvent):void
{
trace("connected is: " + nc.connected );
[Code].....
The only work-around I see for this is saving the initial number I get from the metadata duration, and running a timer to constantly check for when the current ns.time matches metadata and then run my reset function.
Quick question - I have the following setup:
(1) An ec2 instance with an SWF on it - this SWF plays streaming video - i.e. is a video player like JWPlayer
(2) A streaming video distribution set up via Cloudfront
If I stream the the video via RTMP from Cloudfront to the SWF (which is on ec2) - would I incur charges for data transfer into the server (i.e. for data being read by the SWF) and out of the server (i.e. for data being displayed by the SWF to the user) on account of streaming the video to users (assuming that data transfer into and out for the server is being charged for)?
