Flex :: API For Speex Codec In Flash
Apr 16, 2010With 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?

Actionscript 3 :: Flash SPEEX Codec Conversion For Google Speech API
Sep 1, 2011People 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:

Actionscript 3 :: Flash/Flex Speex Audio Decode, To Play A Speex File?
Dec 7, 2011I 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.
Flex :: Play Speex Encoded Audio In Flash Player?
Mar 22, 2011I 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.
View 1 RepliesProcess Flex/Flash SPEEX Audio Data On The Server Side?
May 4, 2011I'm implementing a very simple audio-only RTMP server.I have my client code like this:
// get the default mic
var mic:Microphone= Microphone.getMicrophone();
// best quality (picks up all sounds, no transmission interruptions)[code].....
Then on the server, I keep receiving audio packets with size of either 43 bytes or 11 bytes (no other sizes found yet).My questions are:
Why do I get size of either 43 bytes or 11 bytes (from SPEEX encoding?)?
Is the 43 bytes = 1 head byte + 42 data bytes?
What is the size of 11 bytes?
How should I process or convert the SPEEX to raw data, so that my server side app can use this audio data? My current implementation:
I pick up all 43-byte packets (drop all 11-byte packets);
Skip the first 1 byte;
Decode the left 42 bytes using Speex library.
How should I convert the raw data back to SPEEX audio data?

View 2 RepliesFlash :: Encoding Speex Into A SWF Version 10 Sound Stream
Mar 1, 2012Adobe'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)

Jan 31, 2012Right now I am working on an AIR 3.2 application which lets you stream a video to a Flash Media Server and saves it on a hard drive.This sequence works fine with the standard Sorenson codec but I want to use H.264 for my videos. I found lots example c ode and implemented it in my code, but when I record a video of myself I am unable to re-watch it afterwards.I found how to implement a H.264 encoding in a realeyes blog post here. My code is here.It saves the video as a .f4v file, but my browser (I've tried the latest versions of both Chrome and Firefox, with the latest Flash) and also VLC are unable to load the video. I also used a program called Movie Player which is able to open the file but can only show the first frame and the audio. Neither am I able to upload the video to YouTube because they do not support the file extension.Here is an example video file it saved: H264Test1.f4v.My question is: How do I stream and save the movie with a file extension that I am able to re-watch while using the H.264 codec?

However, when I try to import it into Flash, I get the error message

Is this some kind of protection on the audio? What am I missing?
Media Server :: Changing Video Codec For Recording?
May 7, 2009I am using FMS 3.5 and Flash CS3 (though using action script 2 at the mo)What I have is a simple program that records a webcam and saves the result as an FLV. - Note, I am doing all this locally, NOT over the internet or a local server. FMS is on the same PC as the program.
1) The frames per second does not seem to be fixing to 25fps, but instead seems to be around 15fps depending upon which pc I use. I'm using: cam.setMode( 320, 240, 25 ); to set the size and frame rate in flash.
2) When I get the properties for the resulting flv, it says it is using h.263 codec. Is there a way to change the codec that is used (to say h.264)? Or is this dependent on the version of flash used? ie. would creating it in flash 9 using AS3 give a better quality result?

View 1 RepliesFlash :: Flex - Live Preview On A Flex (compc) Generated SWC
Jul 20, 2009Does anyone know what criterea Flash uses for discovering the Live Preview class for a Component? Background We are attempting to automate the creation of a SWC that contains a component to be used from Flash. We are able to make it visible to flash by modifying the manifest.xml and wiring up the component definitions. However, the component cannot be dragged onto the stage (or library), presumably because it has no form of LivePreview. To give better clarification of where we are coming from, we've noticed the following in SWCs exported from Flash (using swfdump):
fl.livepreview.LivePreviewParent contains the same mod attribute as the visual component in the manifest.xml file fl.livepreview.LivePreviewParent is exported as a symbol The short-named component (ie. no package, referenced in the components definition in the manifest.xml) is exported as a symbol However, I can see no other differences between that and the SWC from Flex. We can obviously use JSFL to perform the task, but we'd rather not install Flash on the build server.
