Actionscript 3 :: Stream Playback From Wowza Has Audio Crackling On Flash Player
Feb 2, 2012
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 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'm trying to playback some sample data through the new real-time audio capabilities of Flash Player 10. I started with the example given at the bottom of this page on livedocs, which seems to work fine and plays a crystal clear tone.I assume that the two writeFloat's in the example write to the left and right audio channels respectively and that the data being written is 32 bit (because of the float).
However. I seem to be having trouble converting my old 8 bit audio data to a format that is understood by this interface. When I playback my sample data I can vaguely hear the sound I'm expecting but it is massively distorted. My sample data consists of raw 8 bit samples that ranges from 0..255 where 127 is silence.
I've been trying different conversion formulas but I seem to be missing some vital information regarding this conversion.
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 have an mp4 file with the audio sounding perfect that I'm running through Adobe Flash CS3 Video Encoder to convert to an flv which I'm trying to then embed in a fla.My problem comes in the fact that after its embedding when previewing it, the sound quality has -significantly- deteriorated to the point where it sounds crackly and echoing. I've tried changing the sound data rate to maximum, but it makes no difference at all.
I'm trying to force the Flash player to play video files without showing screens. I did try to set vidDisplay.visible to false. But it seemed not working at all.I was doing was try to build a generic media player. Whatever the source is(audio or video), the control panel always the same, namely, a mp3 player panel is always displayed:However, when I stream in a video file, it would end up overriding mp3 panel with a partial video screen. I don't have enough reputation to upload images...
I have a VLC player streaming my webcam video through RTSP on 5544 port, the video is encapsulated with MPEG-TS and compressed with MPEG-4 for both audio and video (as is VLC's default I suppose)You can access the streaming video with the following URL:[URL] All is working till here. I could also change transport protocol/incapsulation, that's not a problem since VLC allows me to do it.I want to develop a silverlight player (preferred) or a flash player capable of reproducing the stream (audio and video).I don't know how to do this.The question is: I could not find a link on the internet on how reproducing a VLC stream with a silverlight(preferred) or flash applet in a web pageSince I'm not a Silverlight/Flash developer.
Since FMS has no options to stream to an ipad of iphone I tried to let FMS stream to a Wowza server by using NetConnection / NetStream classes. It seems to work (not getting any errors in the logs) but nothing happens when I try to read the stream from the Wowza server.
I want that my spaceship gets louder when my mouse moves away from it (and vice versa). Problem is that my function produces an annoying crackling sound I can't get rid of when I move my mouse away from it (and vice versa). The sound file is ok so far.
Code: shipSpeed = (abs(player.x - playerPrevPt.x) + abs(player.y - playerPrevPt.y)) / 2;//the ship's speed gets calculated //this is used to determine whether the ship's volume of its sound shall be increased or decreased
I'm currently creating a whiteboard in Flash, and I want to be able to record all of the user interaction for later playback. Is it somehow possible to create a video of what the user is drawing?
I'm trying to create a webRadio player, wich different sources. On a click on a button, the player plays the corresponding flow. I would like to display some informations, like : current music, url, description, I think it's possible to have all those informations, because when I play my. files in my audio player (winamp), I've got them. Here is my code corresponding to this part :
need to create a player to stream audio files (mp3 and other audio extentions) in my website. To create this player I used flash cs3 and actionscript3.I found actionscript 2 is easyer to creat and get duration (mysound.duration) but in ac3 I can't get sound duration with this syntext : "mySound.duration"attention : In ActionScript3 BEFORE loading is completed , I need my audio file in player to show duration and displayed minute and second in the stage.I tried so many solutions in the internet but all of them provide sound duration AFTER loading is Completed (but I need sound duration BEFORE loading is Completed)attention : My audio files are multi bitrate rang exp.(24 kbs , 34kbs , 128kbs or higher).I am trying to get audio DURATION of audio "total bytes" but these solutions just are right for only 128kbs audios.
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.
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've had FMS running on my local machine for a while and have had a little experience writing FMS apps, but I've just tried recording audio for the first time using the standard vod application and I keep getting a "Write access denied for stream" error. My AS3 code is copied and pasted for various examples and am confident that it works.
I'm running Windows XP service pack 3 & FMIS 3.5.
I've had a look at the vod/media directory and under windows->properties the read-only attribute is ticked. Every time I un-tick this it reverts back to being ticked. I've googled this and MS say that most programs ignore the read-only attribute and that it only really applied to files. I've also tried the MS fix for setting the read-only attribute via cmd and still no joy (doesn't fix read-only attribute or FMS recording the audio after setting via cmd).
I've also tried our dev server install of FMS (running under linux) and am getting the same results.
Here's my AS3 code...
private function initApp(event:Event):void { removeEventListener(Event.ADDED_TO_STAGE,initApp);
I am having trouble getting audio stream meta data from an Akamai FMS stream. Everything is undefined and I'm not sure why. I am hoping maybe someone will notice something that I am overlooking. The stream is connecting and playing without a problem I just can't seem to figure out why all the meta data is undefined.
I'm interested in learning how to decode and playback audio in ActionScript 3. I understand how to write bytes to a Sound object using the SAMPLE_DATA event, so that's not really a problem. What I want to understand is how I could implement alternate audio formats for native playback inside of Flash Player. I guess what I'm asking is: how do I take something in X format and "convert/decode" it to WAV format and write the bytes to a Sound object, playing back the audio? I'm interested in writing a decoder for FLAC audio and possibly OGG audio, as these seem to be some of the most widely used open source audio formats
mp3 playback security with Flash player. I am making a mp3 player and don't want to give user access to download the mp3 files from server. But according to Flash player functionality, it's getting downloaded in cache. Also with Firbug user can see the mp3 file path.I would like to have any good suggestion for this development, without streaming server. Is it really possible to secure mp3 files with Flash player? If yes then please let me know your feedback for the same.
Because the player optimizes framerate, antialiasing etc dependent on the performance capabilities of the platform upon which it is running, it was nearly impossible to ensure animation syncronization w/ audio. If the audio were on the timeline you could set sync params to stream, but if the audio is loaded programically forget it .. well until AS3 ..The following code throttles the player framerate to lock step the animation to the audio .. not perfect but the principal works ..
Let me first establish what I want to do:My user is able to record voicenotes on my website, add tags to said notes for indexing as well as a title. When the note is saved I save the path of the note along with the other info in my DB.Now, I have 2 choices to do the recording, both involve a .swf embedded in my site:
1) I could use Red5 server to stream the audio to my server and save the file and return the path to said file to my app to do the DB saving, seems rather complicated since I would have to convert the audio and move it to the appropriate folder that belongs to the user in a server side Red5 app, which I'm not very aware of how to build.
2) I could simply record the audio and grab its byte array, do a Base64 encoding on it and send it to PHP along with the rest of the data that is necessary (be it by a simple POST or an AJAX call), decode it on the server and make the file with the appropriate extension, audio conversion would also occur here using ffmpeg, this option seems simpler but I do not know how viable it is.
I'm interested in setting up a site where I can put MP3 files on my server (outside the web root) and stream them to a flash application. I'm not talking about progressive download here. The basic idea is to let visitors hear a band's music without actually downloading or caching an mp3 or SWF which could be located as a file and saved or ripped. I have seen this awesome tutorial on streaming an flv and was wondering if anyone can recommend a PHP/AS3 solution which would let me do the same for audio.
This problem is happening is both IE8 and IE7. I have a small swf compiled with flex. It's basically just a wrapper around audio streaming functionality. All the controls and such are in html with javascript. I load the swf using swfobject's "static" method. This works great in Firefox and Chrome. In IE, the swf loads correctly, but as soon as I try to stream any audio with it, I get an error. EDIT: I've reduced the code quite a bit to try and find the problem. You can see the new version running here. Here is the error, html and flex files for my reduced version:
Is it possible to have a Flash player that only plays the AAC audio of Flash video (FLV file)? In other words, we need the video muted and only play the audio.
can Flash stream audio from a different domain? Like, if I have my .swf on www.a.com and then my .mp3 on Url..., will trying to stream it work?Also, is there a way to have music saved on the person's harddrive or cached so that if they load the song, they dont have to load it each time when you stream audio or load it from another source?
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.
