Flash :: Encoding Speex Into A SWF Version 10 Sound Stream
Mar 1, 2012
Adobe's "SWF File Format Specification v10" says that Speex encoded data can be used for streaming sound (a little clarification of the "streaming sound" definition here: "The SWF file format supports a streaming sound mode where sound data is played and downloaded in tight synchronization with the timeline. In this mode, sound packets are stored with each frame." - this has nothing to do with any FMS streaming, no ActionScript needed - just plain SWF).This should be accomplished by using a single SoundStreamHead2 tag with StreamSoundCompression set to 11 (which means "Speex", as stated in the abovementioned Specification) and then N pairs of ShowFrame and SoundStreamBlock tags. However, this does not work - Flash Player plays no sound when playing the SWF generated by me this way. Please note, that I am capable of generating such SWFs containing streamed MP3 or PCM data, which then play perfectly. Just not Speex...
I strictly conform to the Specification:URL...I tried the streaming sound approach as well as the event sound - both do not work.Moreover, I was not able to find (anywhere on the Internet) any sample SWF with streaming sound (nor event sound) encoded in Speex. Do they even exist? Anyway, Flash CS5.5 is not capable of generating them.I would just like to know whether Speex support for SWF streaming sound can be found anywhere else than in the Specification. (I know that FLV can contain Speex and that Flash Player can stream Speex from a microphone and that FMS can stream Speex to its clients, but this is not what I am asking for)
I want to play *.spx files which encoded by Speex on the Web.But I have no knowledge of Flash/Flex or any Flash Audio codec. After Google search for a whole day, I got some solutions, that is:
Do something wrapping Speex files with a FLV container because that the Speex is only playable as the audio codec in a FLV container.Now I can play a SPX-Audio-Only FLV file in Flex, I use netStream.play("audio-only-speex.flv"), But I donot know how to wrap a Spx file with FLV container using ActionScript.I have never heard FMS stuffs before, as well as I'm not sure whether my virtual host can support or not...Convert every Spx files to MP3.
I think the best solution is decoding Spx in AS3, Yes, I'd like to make a Spx Flash Player.So, I downloaded Speex Library from speex.org, installed Adobe Alchemy. After ./configure;make the libspeex, build libspeex/speex.c out a libspeex.swc via Alchemy. then, I donot know how to do next. How can I decode the speex audio with AS3? My libspeex.swc: [url].....
In addtion, should I rewrite the libspeex using Alchemy API before build the libspeex.swc? Although I am not professional in AS, but I have a strong ability to learn.
I use wowza server and need to build a flash client to publish different encoding qualities streams. Does it has any open source or paid with source code flash client products?
We set up a Flash Media Server and we are trying to figure out how to protect our live encoding url. Seems like anyone with a Flash Media Encoder and who knew the location of our server could publish a live stream.
I have an MP3 file in Flash 5.5 that I have edited in the properties panel of the frame where the sound is...I basically cut a couple seconds off the beginning by editing the timeline. It plays fine when I'm in Flash, but when I publish the movie, the sound is published unedited.
I have a layout with narration and a nav bar. When I click a nav button for section 2, the audio from section 1 (set to stream) continues to play over the audio for section 2. This cumulates so if I click buttons for sections 3, 4 and 5, I get five audio files playing on top of each other. Sections are individual movie clips with embedded audio streaming on a Sounds layer in each movie clip.
I need to read sound stream sent by flash audio in my C++ application (C++ is not a real limitation, it may be C# or any other desktop language). Now flash app sends audio to another flash app but I need to receive the same audio by desktop application.So, is there a standard or best way how to do it?
I have a broadcasting project that I've got where the host of the show can have multiple sound effects they can use on their show.I'm wondering if the only way to go about this is for all the clients listening to the show need to download the mp3 of that sound effect or if the sound effect could come from the host ...like combining his mic (for his voice) but also straight audio (the sound effect) into the stream.
I have made a 5 min animation with stream sound. Its playing perfectly in PC. But in mac, its not playing. Stream sound starts from frame 60. So mac plays the swf plays till 60 frame, after that it pauses. I tried importing different sound format (wav, aif, mp3) and tried with all sound export setting but the problem remain same; its playing only till 60.When i removed the sound, it played till end. Even with event sound, it plays till end. But with stream sound, the problem. The problem is only in mac; in pc its perfect.I am using VMware Mac OS x leopard in window xp for testing purpose.
With AIR 2 allowing access to mic data, it's possible to save/process audio locally. Adobe provides a WAVWriter example but is there any API access to the Speex codec?
a client asked me to incorporate a flash version check in a flash application i made for him.it should read something like: "you have flash player 10.x.x.x.x.x.x.x the current version is 10.1.x.x.x.x.x.x"the user veriosn is easy to get with Capabilities.versionbut is there an url on adobe's site to get the string of the current downloadable version from?
I need to validate an uploaded SWF to ensure it meets certain Flash and ActionScript version limitations. Anyone know a good Python library to parse metadata out of a SWF?
i m using adobe flash cs3 with AS3 . I have updated my flash player in version 10 and it's activeX. But while I gonna publishing it , I do not get option of version Flash Version 10 in Flash Tab of File>Publish Settings. How, can I have option of Flash Player 10 ?
Are there any plans to upgrade the SDK to version 8 or 9 or release a updated flash version for the Wii. It's ridiculous that Adobe has not done this already considering the sheer volume of people using the Wii web browser.
I have tried really hard to find an example showing how to play speex encoded audio in flash. I tried the following code -
var connect_nc:NetConnection = new NetConnection(); connect_nc.connect(null); var stream_ns:NetStream = new NetStream(connect_nc);
[Code]....
I tested the above code with .flv videos and AAC encoded audio files and it works just fine. But when I try stream_ns.play("sample.spx") I get a stream not found exception.
Am I using the wrong container (.spx) for speex audio. Is playing speex audio from a file supported?
From what I have read, using Speek over Nellymoser is advantageous, but I can't figure out how to use it with a Flex 4 Microphone object. For instance, the last code line:
I am able to record sound from microphone, encode it using SPEEX and write into ByteArray. I want to play it back. If I try using Sound object the audio is messed up. Speex uses 16kHz for encoding and Sound Object needs 44.1kHz for playing audio. How am I supposed to play this encoded sound.
People have figured out how to use the Google Speech API (Speech-To-Text). I'm trying to get it working with Flash Speex codec, and I just can't figure it out. I've tried inserting frame size byte before each 160 bytes (as some sources say), but this doesn't work. So I post a challenge to somehow translate the flash speex bytes for Google Speech API to understand. Here is basic flex code:
I identify my current installed debug version? Basically, I am using Flex 3, for past 2-3 days whenever I launch any Project or debug it, I get the message box saying "Flex Builder requires a more recent version of Flash Player." It says my curent FP as 9.0.115.0 and debug version as 9.0.45.0. However, my actual FP version if FP 10.0.22.87. I don't understand why this confussion! I don't know how can I know my actual version of Debug player.
I placed my audio in the timeline, but I want it streamed rather than event driven because people will be jumping around the timeline When I change the sound to Stream the audio gets incredibly choppy.
i make my first flash homepage this time, and i got a problem with my intro.It takes a lot of time to make this work because its my first projekt.So iïve made a flv file as the movie clip and an mp3 for the sound.And i lode it by Actio Script.Here is my code.
//Intro-Video laden var IntroConnection:NetConnection = new NetConnection(); var IntroStream:NetStream;
I load icecast stream into Sound object, using some tricks to overcome memory leakage. Generally it works quite well, unless someone reloads either icecast or stream source program on the server. In that case flash player just mutes itself forever. I'm looking for some way to detect this case internally and reload the stream without refreshing web-page.My problem is caused by the fact that onComplete event for some reason doesn't trigger, maybe there's another event happening, but I just couldn't find any.One thing that I tried was noting down stream progress point and checking consequently for 200 times if it stays the same and if it did I was manually calling stream reload function.
I am stumbling across this issue as I open and close a sound stream. This is the code I use, not sure if closing and opening a stream on the same function is a good idea.
I'm working in Flash CS3. My animation is about a minute long, with a single audio track that plays from beginning to end. The sound quality is noticably better when I set the synching to Event, but unless I set it to Stream the sound falls behind the animation. Is there any way to maintain proper synchronization with the Event setting? Also: will the lag be consistent on different machines and players? I thought about adjusting the timing of the animation so that it matches the Event-set sound in playback, but that's such a clunky a solution it seems likely to cause other problems.
I have a little sound stream script here, but sometimes if you press play to the next track before the current has done loading the next track doesn't comeplete loading
package player { import flash.events.Event; import flash.display.Sprite;
