Flash has an API to control the volume for a Sound object. Can volume be controlled like this currently or is there support planned for <audio> or <video> html5 elements?

which property should i change or bind a slider to in order to be able to change the sound volume ?
hope i'm explaining this the right way. i'm using the flash flvplayback component to play a video. i've stripped the audio from the flv and am playing it, along with another audio clip, on the timeline at the same time. volume has been set for both clips, but i need to allow people to adjust the volume from the volumeBar that exists inside the video player. it's built in as2.
View 1 RepliesI'm creating a flash presentation that contains some externally loaded video's (flv), voiceovers and a background music. I would like to be able to control all these audio streams with one control. So basically I'd like to change the volume of the entire movie. Is this possible?
I know there's something like the Sound object with a setVolume() method, but that's only to control one stream as far as I know.
I've got a presentation that features an audio loop for background music and streaming audio on the timeline for the voice over.When I try to lower the volume of the background music (sound object), it also effects the voice over (streaming).I'm a total novice, so try to use laymen's terms.[code]And this is on the Frame that contains the movieclip with the voice over.I'm trying to fade the background music ONLY:[code]

View 1 RepliesI have a video streaming application that uses a Red5 server. The stream from Red5 is represented through an embedded video object on stage. I need to be able to control the volume of this video object, but so far I've been unsuccessful despite following tutorials like this one: http:[url]....Here's the relevant code:

I have a button calling volumeChange onRelease, but when I trace videoSound.getVolume() in volumeChange, it comes up as undefined. However, if I trace videoSound.getVolume() after I define videoSound, it comes up as 100, but any attempt to use videoSound.setVolume in initNetStream is futile.
I want to know if it is possible to use javascript, flash or flex to make a youtube video player that is capable of controlling left/right audio channel volume. For example, mute the left channel and play right channel audio on both left/right speakers.

View 1 RepliesMy compnay provides webcasting services to numerous clients, and we currently use Windows Media Encoder as our base software for these projects. However, I'm interested in switching to Flash Media Server, but need to figure out one issue and how to implement it in such a way like how we are currently using Windows Media Encoder.
We need a way to stream out a live audio/video feed AND have a way to control a presenter's POWERPOINT slides and have them advance by our command when streaming live.
Basically, the way we do it is we will stream out audio/video from WME and also use the encoder's SCRIPTING functions to send out a "url" from the encoder to the actual page in which the viewer is watching the live embedded stream. On that page is an embeded/internal frame which we can specify (using the id/name) that the url gets loaded, and this actually advances the slides (or more so pulls up a pre-created html page of the next slide in the person's powerpoint, which is actually a screenshot or exported image of that slide and embedded within a specific HTML file and hosted on the same server as the embedded player/html file)
Would there be a way to send out this same type of script using FMS? I've been playing around with it and notice the interface itself does not have a built in scripting function like Windows Media Encoder does. However, I did read somewhere that it supports ActionScript... but I have no clue how to implement this feature.
I am just curious how it might be able to go about doing this? Is there a way to use an [action]script with FMS and have it send out a URL to a specific frameset embedded on the same page as the Flash Media Encoder Playback?
Hopefully this make sense and that someone can point me in the right direction. Switching to FMS over Windows Media Encoder is the way I would love to go, just need to figure out how this could be done.
Would a better method be converting the powerpoint slides to a swf or flv file, embedding that file within the same page as the FMS playback, and somehow using a script to "advance" the frames/slides/scenes within that file? I also heard something about Flash "Shared Objects" and how this could be a way of controlling a swf file remotely.
I'm trying to control the video playback of a live video stream using ActionScript 3 code in Flash Professional.
There's a FLVPlayback component on my stage titled "flvPlayer", and in Frame one of my "Actions" layer, I have the following code:

import flash.display.Sprite;
var vidURL:String = new String("rtmp://www.mycompanyserver.com/test/live/livestream");

I can get it to work by adding the source to the Compenent Parameters window, but I need to be able to access those parameters in code.
I'd like to be able to tell my ADG to set a specific row to be highlighted and update the adg rendering to match such new value. Note: highlight != selected.
I thought perhaps setting highlightUID would do the trick, but I can't seem to get the ADG rendering to update.

I have a video chat application where there can be 6 participants. What I would like to do is give the option to each publisher to control their own stream's volume. The code I have looks like this.

private var volumeTransform:SoundTransform;

outgoingStream = new NetStream( nc );

A possible solution can be this : Calibrate the slider and set the microphone gain, a gain of zero effectively is mute and a gain of 100 is full volume.
I need to write a small Flash app that will need to extract a video frame from a playing video. It will not need to be saved to the HDD of the user. I just need to get the image data and display it in the Flash movie. The frame to extract will be chosen by the user, which is why I'd like to do this purely on the client side (though I know I could do it from the server side).
View 2 RepliesIn Flex you can stream microphone audio to an FMS/Red5 server using NetStream.attachAudio, which requires a Microphone object. Is it possible to stream audio through the NetStream from somewhere other than a Microphone? For example, from a file/embedded resource?
The reason I'm asking is that I'd like to be able to run automated tests that don't require using an actual microphone.
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.
Is it possible for flash to access the windows xp system volume controls?I assume flash can't by it's self, but can flash be used to trigger a function in another language that can access and alter the system volume? At least detect if the audio is muted on the system and give the option to turn it on.The flash movie would be embedded in a browser. The content of the movie has audio that is required. We want the user to be able to control the system volume from within the flash movie.

Im able to stream audio with the following code:
Code:
sonido = new Sound();
sonido.loadSound("images/warp.mp3", true);
sonido.onSoundComplete = function() {
sonido.start();
sonido.setVolume(50);
}
I use this code to disable the audio file:
Code:
sonido.setVolume(0);
}
As soon as the audio file repeats, the volume goes up again.I need to know if I can keep the volume as it is once the audio loops again.
I am using Flex and FMS to develop a video conferencing application. I am using DynamicStream to automatically switch incoming streams to the appropriate bitrate depending on the available bandwidth. I was wondering if there is anyway in which I can instruct the DynamicStream to allow more bandwidth for audio (obviously at the cost of losing some frames from the video).

Let's say I have a slider that can go between 0 and 1.The SoundTransform.volume also ranges between 0 (silent) and 1 (full volume),but if I use a linear function,let's say SoundTransform. volume = slider.volume, the result is rather not pleasing.I really haven't studied the human ear,but I overheard once that human perception is logarithmic, or something similar. What algorithms should I use for setting the SoundTransform.volume?
View 7 RepliesDoes anyone know of an existing flash (swf) based audio control that is available (free or commercial) that provides a timeline waveform visualization with the ability to select and play a portion of the timeline?For example, the flash control used by this website... http:[url]....It does exactly what I'm wanting to do. I need this capability to allow a user to mark a section of an audio file which can then be synchronized with other visual elements on a web page using javascript.
It is important that the user be able to see the wave form of the audio because they can save time by visually guessing where certain sounds start and end in a file. The user can then select this block of the audio and preview the sound and tweak the selection if need be.

I have this site I'm doing in Flash with an embedded video.The site has background music that is loading automatically, but when the embedded movie loads, the volume on that is mixed in witht he sites music.If you mute the sites background music, it mutes the video sound as well. Make sense?How can I seperate them out or make the sites background music not load on that particular page.
View 1 RepliesI want to add tracking to our Flash-based media player so that we can provide analytics that show what sections of videos are being watched (at the moment, we just register a view when a video starts playing)
For example, if a viewer watches the first 30 seconds of a video and then clicks away to something else, we want the data to reflect that. Likewise, if someone watches the first 10 seconds, then scrubs the timeline to the last minute of the video and watches that, we want to register viewing on the parts watched and not the middle section.
My first thought was to collect up the viewing data in the player and send it all to the server at the end of a viewing session. Unfortunately, Flash does not seem to have an event that you can hook into when a viewer clicks away from the page the movie is on (probably a good thing - it would be open to abuse)
So, it looks like we're going to have to make regular requests to the server as the video is playing. This is obviously going to lead to a high volume of requests when there are large numbers of simultaneous viewers.
The simple approach of dumping all these 'heartbeat' events from clients to a database feels like it will quickly become unmanageable so I'm wondering whether I should be taking an approach where viewing sessions are cached in memory and flushed to database when they become inactive (based on a timeout). That way, the data could be stored as time spans rather than individual heartbeats.
I've reviewed all the documentation and Google results surrounding this and I think I have everything setup correctly. My problem is that the symbol is not appearing in my app. I have a MovieClip symbol that I've embedded to my Flex Component. I need to create a new Image control for each item from my dataProvider and assign this embedded symbol as the Image's source. I thought it was simple but apparently not.
Here's a stub of the code:
[Embed(source="../assets/assetLib.swf", symbol="StarMC")]
private var StarClass:Class;
protected function rebuildChildren():void {
iterator.seek( CursorBookmark.FIRST );
while ( !iterator.afterLast ) {
child = new Image();
var asset:MovieClipAsset = new StarClass() as MovieClipAsset;
(child as Image).source = asset;
}}
I know the child is being created because I can draw a shape and and that appears.
