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?

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)?
Does anyone know if there are any classes that expose information about bandwidth usage? For example, I would like to know when my Flash file is really pushing the bandwidth by loading a bunch of stuff (like images), versus when its basically sitting idle.
Now I know I can get stuff like progress events from an individual load but thats not what I mean here. I want to be able to get a current level of activity for my entire movie which is currently running....not information about a particular item which is being loaded.
We need to record and display daily/weekly/monthly statistics on vod application usage, we are working with multiple application and need statistics for each one of them individually parameters required are bandwidth, number of connection, view time ...

View 1 RepliesI have a simple slideshow composed of 4 images repeating themselves. Basically, the movie loads the first one, increases a numeric variable, and then unloads it with remove child, and loads another one corresponding to what the numeric variable is. When the 4th image is about to go away, it resets the variable back to 1 to signify the 1st image, then loads the 1st image and the process repeats. I've attached the .fla if my explaining skills are subpar.
The code for loading the photo depending on what the variable is below. (In a previous frame, "photoload" is set as a new Loader and the numeric variable "whichphoto" is set to 1.)
Code:
if (whichphoto == 1){
photoholder_mc.removeChildAt(0);
photoload.load(new URLRequest('homebg01.jpg'));
[Code]....
My question is when I have flash load the 1st image for the 2nd time, does it use up more bandwidth (as if it was loading the image for the first time)? Or is the image already saved in the viewers memory once all 4 images have been loaded for the first time?
I'm trying to stream a webcam from 1 server to many client, what I really need to know is :1. How to adjust a bitrate video for bandwidth streaming, is it enough just using a Camera.setQuality() ?2. If u set Camera.setMode() at large resolution, for example at 1024x768 is it could make the bandwidth for client access increase too ?I mean is it affect the bandwidth for set the resolution at small (ex: 160x120) or set at large (ex: 1024x768) resolution.3. Same as number 2. just it was for video=new Video(w, h) . Is setting a video size affecting the bandwidth ?

I've just been asked to create a video player which automatically chooses the correct bitrate video to stream by detecting the bandwidth.I have no experience creating a video player so I'm looking for links/resources to do some research on the topic.Has anyone here created a video player in Flash? Would it be better to create in Flash or Flex?Once again, I have no prior knowledge in this type of creation and could use an experienced developer's opinion on what the first step is towards progress.
View 3 RepliesWe have an application that is using FMS to share slides (swf,jpg, etc) with another client. We added a video as an option. We would like to verify as often as possible the bandwidth quality between communications in order to suggest the user to close video if we notice bandwidth is not optimal.
We've been experimenting doing a bandwidth detection every 60 seconds, but I am wondering if there are specific guidelines to do this for live video, like how many times one should verify bandwidth? Is it ok to take one reading or should we take a few readings and then average out?

My problem is going to be hard to outlay in detail due to NDA's I am bound to, but the gist is this..I have a swf application the progressively streams content from a cdn edge server.I have built a video player class and instantiate a new one for each new piece of footage I find.Naturally this requires good memory management to ensure no leaks..... and herein lies the problem (surprise).
I have unregistered all my event listeners (not using weak at present) and nulled all objects from my media player object.I slice it from my list and call a destroy method that cleans up all objects setting references to null. Once this is done I call System.gc().My profiling tools are showing that my memory usage is continuing to increase linearly for each new video clip. The jump is about 5mb each time the approx size of each video file.
Is the built in "Video" component on the stage (players all share the same one) a built in type?
Currently, 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 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.
View 5 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 trying to connect to an rtmp site using flash builder 4. I have created a class to handle the connection. This code works (traces a connection error) if connection.connect(null); but if i try to put an rtmp site in the connection, it doesn't do anything. I have it scripted that if the connection fails it should trace and error message but it just seems to stop. any thoughts?

I 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.
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?
Am developing an application with Flex 4.5 & Flash Media Server. I need a visualization curresponding to the plaing track . It is possible with SoundMixer.computeSpectrum(bytes, true, 0) in case of progressive downloading. But not working with rtmp streaming.

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'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".
