I am researching the inclusion of Flash in a PHP/MySQL application I am building to stream audio.I have done a lot of searching, but have yet to find which audio formats that Flash can stream.I know that MP3's can be streamed.
View 1 RepliesI am trying to stream audio to my flash application. I got it working with a test MP3 file. But the problem is that MP3 encoders are protected by patents and require license fees.(I am living in Canada) Isn't there a open audio file format supported by flash?
View 1 RepliesI 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 am new in action script 3.0. i am trying to build an audio player which will stream audio(mp3 etc.) from wowza media server. the player needs to have a play button, stop/pause button, a play progressbar and a volume scroll bar. i am using NetStream object to paly the audio
View 1 RepliesI 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.
View 2 RepliesI 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.
View 3 RepliesIn using Flash Live Media Encoder to aquire a webcam video and to send it to a Flash Media Development Server 3.5 for live video streaming to one client by the same local network.The client device doesn't support flash player but is able to read and play flv video format.So, if i get a flv video file from apache 2 it works.But I don't know how to get a live video streaming from the server. The client application needs a flv file to point to.Does FVS generate a flv file for live video streaming?
View 6 RepliesI would like to serve high quality video (H.264) between a server and a single Flash Player client with low latency (RTMFP). The single client will be controlling a robotic device and seeing the results through the video stream, so low latency is important.
Option A: The Flash Player supports low latency streaming of video between two P2P nodes via the RTMFP protocol in Flash Player 10. It uses the Spark codec to encode the video and as far as I know it is not possible to encode using any other codec in the player.
Option B: Flash Media Live Encoder does support live encoding using other codecs (On2 and H.264) but cannot act as an RTMFP peer - this option would require Flash Media Server in the middle.It seems I cannot stream video to a single client over RTMFP with anything other than Spark.
I'm building a website that is supposed to record and upload audio to a server and also be able to play said audio. Currently I have a BB app that does the same, I record the audio in .amr format, send the bytes over to the server and convert it to an .mp3 file with ffmpeg. How can I manage to record audio and save it in .mp3 format? With Flash, HTML or any other means. My website is being built with PHP under the CakePHP framework.

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 was wondering whether MP3s or WAVs would be better to avoid syncing issues. Also, what audio stream settings would be best?
I was also wondering if you can manually play the audio track by moving the play head over it. I've tried multiple times with multiple settings to no avail.
I made a Audio Player in flash, using AS 2.0. In this Audio Player all songs getting form some external path through XML. It only playing MP3 format songs .

View 1 RepliesI 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?

View 1 RepliesI 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.

How exactly am I supposed to do this, and does anyone have a sample video controller/viewer I could borrow to test this out?

View 4 RepliesI 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.
I am trying to create a simple desktop app to play a live radio stream from a shoutcast server. I cannot get it to play. I am now wondering if it is even possible using the Flex/Air platform. Here is my code:

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?
