IDE :: Progress Bar For An Audio Player Streaming Audio From Wowza Server?
Feb 24, 2011
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
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 a custom Flash video player that uses the NetConnection and NetStream classes to stream mp4 files from a Wowza server. Lately the playback has been having audio problems. The sound is crackled and in some cases may cause the Flash player to crash. This is not consistent between files. Meaning that a file that was played once with bad audio could be fine 5 minutes later when played again from a new instance of the player , but 5 minutes later have the same problem.
My thought direct me to thinking this was an encoding problem, but that wouldn't explain how one second the playback is fine, and once refreshed messes up again.
I should note that the Wowza server does not stream the entire file but only a portion of it based on various parameters it gets.
I wanna be able to load a .mp3 file outsideside of the library (to conserve file size) which i figured out but i am having trouble with makin a progress bar for the progress of the loading mp3....
The problem is that the progress bar is not working correctly while the music is streaming (not completely downloaded to cache).I can understand why it is so.... (sound.duration is changing untill download is complete)I have a simple progress bar... no masking etc:- .. just using the good old "_xscale"
i am New to flex.Can any one point me to a small piece of mxml code which plays audio files(mp3,wav.....) also which has the capabilities to pause, play, stop.... the audio file. Also this file would be embedded in a html file later on..
I have written a little MP3 streaming player. Nothing big. But on some file, it takes longer to fill enough of the buffer before starting to play. My construct is fairly simple...
var player:Sound = new Sound(); player.onLoad = function(success:Boolean):Void { if (success) { // do something; }} player.loadSound(musicURL,true);
Since I have specified streaming, this will auto play as soon as the buffer is full. What I'd like to do is play a little animation or something while the buffer is filling so the user won't think the player has hung.
I started with a XML driven 3d Carousel and a XML driven streaming MP3 player, mixed them both up, and made a mess.I can't seem to be able to modify the mp3 player to be able to select separate 'banks' of songs.I tried one method of loading mulitple XML files, each one being a single song 'bank'. But that didn't work as the previously loaded 'bank' would stay in the memory. (When I clicked the second tape, both the first track of bank1 and the first track of bank2 would play simultaneously.)
Now what I think I need to do, is load in one XML file that contains all the 'banks' wrapped in an <Album> tag like so:
Code: Select all<Album index="tape1" title="LA Tool and Die" artist="LA Tool and Die" imageURL="images/tape1.jpg"> <Tracks> <Track
[code]....
then when a tape is selected, point the audio player to the selected <album> node.But working that into the working streaming audio player is a bit over my head, as is building a audio streamer from scratch.Included is the file that compiles to the sample with the exception of having the 'multiple XML files' bit taken out.
I have a Wowza Media Server 2 running on Amazon EC2 and I've noticed from time to time a flv is recorded from a webcam using Flash that has audio but no video. It works fine most of the time but from time to time this error occurs
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 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.
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.
We have setup a brand new FMS 4.5 for http streaming to ios devices. We are feeding the source via rtmp to livepkgr application. Upon digesting the iOS feed via the url below, there is no audio being passed. I can check the stream using the rtmp protocol and there is audio. [URL]..
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. And also need audio wave curresponding to the track which is also working with progressive ownloading usinf Sound object.
Anyone know of a skinnable audio player (or something similar to Windows Vista audio control in task bar) that i can embed in my website?
A player that can be customized to use a 'speaker' icon instead of a 'play' icon. When the speaker is clicked, the volume can be adjusted or turned off. The option of being able to autoplay and set the default volume level.
I 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?
I have an audio player that has a custom timeline and playhead. I am using a start and stop drag to move in the time line but the only way i can make it work is to have it play when ever I release the play head. I would like it to stay stopped if the player is paused and play if the player was playing.
My server is streaming binary audio data (mostly mp3 files) to a client (a browser). This client stores the audio data in memory.
What I'm looking for is a flash audio player that I can input the binary audio data so that it can play the audio file.
Preferably, the flash client is merely a bridge to Javascript so that I can handle everything in Javascript and simply use Flash's audio features, but this is not a requirement.
I'm looking for a (free) flash player that I can embed in my site and use to play a .m4a (.mp4 with AAC audio) file that will be obtained using a URL (i.e. it's not local to the server hosting the web page).I've tried searching on google for one, but either I'm searching wrong or no one has made such a thing. Ideally this would be very simple (small user interface with play button and maybe a progress bar) and it would be easy to have multiple instances of on an html page (can create the player with an <object> tag).
I want to implement an internet chat application, I mean, I want a front end, which connects a web cam (mic and speaker). So, I can send videos and audios to a back end server (do flash streaming? but I am not sure what good product out there I can use), and also send both A/V to another computer on the internet. In other words, need a front end that sends local a/v from webcam (&mic) to backend and receives remote a/v from backend to webcam (and speaker) + backend streaming server.
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?
I have read that you can stream protected audio/video to iOS based devices with the new FMS 4.5.Is it also possible to stream protected A/V to a HTML5/JS based Player.
Writing RTMP Streaming Server for streaming AVC+AAC video. And it works fine with rtmpdump. But I can't force it to work in flowplayer and other flash video players.The message sequence after handshake is similar to FMS / RED5 / erlyvideo / haxevideo servers: I've tried a lot of variations.
From Chrome debug console I can see, what all negotiating messages passed to the flowplayer. The last one is onMetaData. And after this the working sample (rtmp://flash.tvwmedia.net/LiveVideo//Live300) gets NetStream.Buffer.Full. And streaming from my server don't get it.
I'm starting with AVC Header message, containing sps/pps. After it first AVC picture passed. After - AAC header and AAC sample. And then AVC/AAC samples. This dumped OK by rtmpdump - I have working flv on exit. But flowplayer and others does not work.
