Streaming Audio / Loading Audio Into Swf First / Then Playing It?
Jan 28, 2012
I think it is loading the whole audio first into the swf, but I would like to get confirmation from someone more knowledgible.[code]I want it to stream the audio when the button is clicked only so that 100 of these swf will not slow down a whole webpage from loading.[code]I only start getting concerned when I noticed that on FF and Chrome, the page loads really quick but when I open the page in IE, it takes a very long time for the page to appear.

I ran a simple live video streaming application for the first time with actual users and ran into a couple of serious performance issues that had not turned up during testing. In this instance there was one video stream from a live web cam and used FMLE at 150 kbps using VP6 and MP3 @22k. There were 16 clients and everything worked pretty good for about 30 minutes. (although some clients said their audio and video were out of sync by up to 3 seconds)
Then individual clients would have either the video freeze or the video would continue and the audio would stop. These clints had to "disconnect" and then "connect" again to the application. This happened to all of the clients at one time or another for several minutes. I stopped and restarted the FMLE with progessively lower bandwidth settings down to 75 kbps but still clients were having the same issue.
I eventually stopped the FMLE and used the applications built in publisher at 45 kbps and that seemed to eliminate the freeze/dropping issue. But of course the video quality was very poor and some clients still reported that the audio was out of sync with the video. The server hosting the FMS application is a quad processor dell with lots of memory and network connectivity. The Flash Media Admin Console performance graph showed the total Bandwidth as 3 Mbps at maximum.

I have this sample code from the e-book: "Learning Flash Media Server 3". The purpose of the code is to create a FLV. The code is not running as it should. When I click on the 'record' button, the label is to change to 'recording', that dosen't seem to happen and also when I click on the 'Stop Record' button, I get the following error:
"TypeError: Error #1009: Cannot access a property or method of a null object reference.at MinRecord/stopRecord()"
[Code]....
My deduction is that the 'if' statement in the 'startRecord' function is not resolving to 'true' and hence the label is not changing to 'Recording'. Also I feel that the assingment to the variable 'ns' of type NetStream is not being done and hence in the function 'stopRecord' I get the above mentioned error message when I click on the stop button. How do I rectify these problems?

The following AS3 code is sometimes causing the audio to play multiple times, almost simultaneously like a crazy echo. It usually works ok with that URL but when I use a [URL]... it always freaks out. On rare occasions I think the issue has happened with local files even. I copied this code from somewhere else so I don't entirely understand it. Do you see a problem with this implementation or is Flash just crazy?

I am streaming to live videos with audio to our webpage, each with it's own accompanying audio. On my laptop, I could stream them without any trouble but it would overheat so I had two new computers built just for encoding. Now, on the new computers, the 2 videos stream fine but only on audio file works at a time. The other just gets hung up on one note of sound and repeats very annoyingly over and over.

I have rather large project that contains several swfs and flvs with audio. The project is published in Captivate (which renders a main swf file). After the preloader screen, a lot of the audio files start playing at once at the beginning of the presentation. I have tried inserting an swf (1st Captivate slide) with AS2.0 command "stopAllSounds". It works as intended and stops all the cacophony. But then, none of my audio plays throughout the 7 minute project. Does anyone know how I can restart the audio?

I have some animation (programmatic, I'm NOT using keyframed animation in timeline), and some music I want to play in the background. Once the music file reaches the end (about 30 seconds long), I want to trigger the end of the animation functions.I figure I could either use an actionscript timer to trigger the end of the animation or a keyframe with actionscript that is placed on the timeline near the end of the song but these methods assume knowledge about the duration of the wave file. If I changed the framerate or updated the external wave file, these triggers would possibly no longer sync upIs there some sort of event listener or other detection method for an audio file to signal it has finished playing? Or maybe there is a way to get the duration of the audio file to use in the timer

I've been working on an audio streaming application for the last couple days. My current progress can be viewed at figmentmedia.ca /test.html.I've got a problem with this release. Look at the tan coloured line, near the base of the window, to the right of the control
buttons (of which only play and pause work). That line is supposed to be a loading bar. As you will probably notice it does not work. The code I've attached is located in the first frame of my movie. The second last line there, "mc_loaded.width =297/(soundClip.bytes Loaded/ soundClip.bytesTotal);", is the one giving me the trouble. After troubleshooting many different options.. none of which worked, I believe.. what is loading may be the variable. Regardless of what progress the bar is showing, it's not showing the progress of the sound clip.

I am interested in streaming audio on my website, but I have no clue where to begin. There are two types of streaming I hope to achieve. The first would be streaming a playlist of songs stored on the server and the second would be live audio streaming. Can anybody recomend any good sites or plugins to use?

I am trying to use some streaming video and audio inside my flash movie, but can't quite figure it out..I have the video saved as an FLV file, and this file was uploaded into my streaming folder on my server. I tried to use a sample player I found, and everything should add up, but nothing is coming through. How exactly am I supposed to do this, and does anyone have a sample video controller/viewer I could borrow to test this out?

I have several flash based lessons that I have created that are being distributed online to several companies. Each lesson has a video that is played within the lesson through the flvplayback control. The videos were supplied by a third party and some of the videos are encoded at 384K and some are at 568K.
One company that is attempting to view the lessons is seeing the following behavior. The video plays for approximately 20 seconds then suddenly the video drops out and the audio continues to play. With the audio still playing the video scrubber rolls back and attempts to start the video again but all that comes through is the audio track again. Now there are 2 instances of the audio playing with no video. This happens a third time and finally keeps going until all the audio is played out.
The IT staff at the company has showed me a fiddler log that shows the flash player making a connection out to Akamai to retrieve the video and then rolling from port 80 to port 1935 and finally to port 443. This would explain the three audio tracks playing
I have read that the flash player will attempt to gather the stream from the stated rtmp location and then if it encounters an issue with a proxy or firewall it will attempt the other ports.So I am not sure if there is anything I can do by design or programatically to alleviate this issue. It appears to me that the company attempting to view this video has some kind of bandwidth throttling program in place that is kicking off this behavior in the flash player.
Is it possible to prevent the flash player from making the three attempts? Would a sudden cut of bandwidth prompt the player to attempt to roll to another port if a network load balancing program suddenly kicked in? If it is bandwidth is that why the audio stream continues to play because there is enough bandwidth for the audio track to get through, but not the video?
I have attached a screen shot of the sniffer output so you can see the rolling ports thing.

I have a flash program that loads an external flv dynamically. I first create an empty movie clip then I attach an instance of the FLVPlayback component using Moviclip.attachMovie();. Then i control the FLVPlayback component with AS2. I have a play and pause button, a scrubber, and a loading progress bar. None of these are components. When I publish and preview the file in Flash CS4, Adobe Flash Player 10, and all my internet browsers everything works fine, all the buttons, the multiple functions of the scrubber, and even the loading progress bar.
However when I uploaded all the files from my computer to my company's server and tested it from there, I recieved audio but no video. All of the various controls still worked for the audio but I couldn't see anything on the stage. If I waited for the loading progress bar to complete and then reloaded the external flv then I got video, but the purpose of this program is to stream the video and I cannot have the users waiting for a preloader.
If you want to look at my FLVPlayback code here it is:
_root.createEmptyMovieClip("lesson_mc",-16381);
lesson_mc.attachMovie("FLVPlayback","lesson_video",0);
lesson_mc.lesson_video.contentPath = page.attributes.url;
lesson_mc.lesson_video.autoSize = true;

Our company has a Flex application (3.0.2) that is having a problem with audio dropping out in Windows 7. The problem appears worse with a wireless connection, but it can't be consistently reproduced there, either. The only thing known for sure is that the problem has not been seen on any other version of Windows.
The application thinks the audio is playing, because it is calling the appropriate event listeners triggered when the audio completes and when any audio cue points are hit. The majority of our audio is streaming via Flash Media Server (3,0,2,201), but the problem was also seen using embedded sound effects. In one instance, several clicks of a button triggered an error saying the sound effect could not be loaded, and then about a minute later, all the sound effects played at once and the user could then continue with the application.

What parameters are required to set an Audio file to Streaming? I have imported both an mp3 file and a WAV file into the library. clicking on a keyframe, I drag either th emp3 or WAV file onto the stage. The audio file can be seen on the timeline. If I set the sync to Event, both of the audio file will play no problem.
If I set eithe of the audio files to Stream, nothing happens, no audio at all. Can I only use streaming audio files another way? I cannot find an option to link ot an external audio file as you can do with video so how do i successfully get an audio file to stream?

I'm working on an app to stream audio from shoutcast. The streaming goes well on my computer and when debugging it with an Android-configuration. But when I deploy it to an APK-file and run it on a Samsung Galaxy S, the streaming doesn't work.
My code for streaming the audio:
var urlRequest:URLRequest = new URLRequest("http://.../;");
var soundContext:SoundLoaderContext = new SoundLoaderContext(2000, true);
soundChannel = new SoundChannel();
sound = new Sound(urlRequest, soundContext);
soundChannel = sound.play();
I've also tried an addEventListener(Event.COMPLETE), it seems my app doesn't get there when running on a Samsung Galaxy.
