Flex :: Video Or VideoDisplay When Does It Make Sense To Use One Or The Other
Nov 19, 2009
Flex appears to have 2 video classes: Video and VideoDisplay. My question is when does it make sense to use one or the other?
What I can tell from initial glancing is that VideoDisplay responds to mouse events because it inherits from IntaractiveObject, but I'm not sure if it's a real difference, because Video seems to have a workaround for this in that you can add your own event listeners.
There's probably more to it, but this is the only difference I can see now. So my question for those who used these objects extensively, can you share your experience when you use one over the other.

I'm writing a Flex video player with a "slow advance" button, and my first approach is to simply toggle between play() and pause() on a timer. I'd like to say something like
if (video.isPlaying) {
video.pause();
} else {
video.play();
}
But I can't find anything like an 'isPlaying' property.

I'm still trying to get my head around the best way to structure event flows. Someone made a lot of sense by telling me that contained objects should be decoupled from their parent containers so they're reusable between containers. Instead of calling their parent's function, they dispatch an event. Sensible! I recently myself in the awkward-feeling situation of dispatching an event on a contained object, from its parent. It seems more intuitive for an object to be the one dispatching its own events. Maybe I'm bordering on breaking the Law of Demeter? Example of what I'm doing: child.dispatchEvent(new ChildEvent(ChildEvent.IM_BEING_A_CHILD)); Am I correct in feeling strange here, or is it a normal thing for one object to dispatch another object's events?

I want to use VideoDisplay components just to show the first frame of the videos, as a preview. So, what I do is
video.autoPlay = false;
video.autoDisplayFirstFrame = true;
But the problem is that they start downloading the entire videos. I've read some topics and docs and I feel that there is a way to avoid it For example, I've tried this line: video.mx_internal::videoPlayer.bufferTime = 1;

My problem that I'm having is I am trying to build a menu consisting 3 buttons, side by side that open and reveal subnavigation buttons on rollover. Then on rollout of the main container button, they close back to where they were. I have built the buttons and everything works great, the only problem is that on rollover of the internal buttons, the main button senses this as a roll out and plays the rollout animation event (closes the button). How can I make the main button not sense the rollovers of the internal buttons and only play the rollout event on rollout of the main button?

As far as my understanding goes Modules kann be used to split an Application into different parts. A big advantage seems to be to be able to load Module after Application Start, to get a better Startup performance. I personally would like Modules to make me able to have an own Code Sandbox for the Module Code. So neither the Main App Code nor the Module Code should influence each other. But for examples CSS Styles from modules influence the Main Application an visa vers. My Question:
1. What can I use Modules for beside Runtimeloading ?
2. Are there options to run code in an own sandbox ? For Example via Loading swf assets ?

I have a VideoDisplay that is able to connect to a source and play. After the connection times out I want the connection to be re-established when my play button is clicked. Right now when I reset the source and play the videoDisplay, it gets stuck in the loading state.

I'm building a video player that run's FLVs and cannot overcome the fact that flex foes not fire the metadataReceived event sometimes. Sometimes it does and sometimes it does not. Therefore the total time of the FLV remains -1. I understand its a known bug , I'm researching about it for a long time now , but could not find a good workaround by now, found one that says to set the buffer time to 0 and try that, but it's also does not work.

I want to build a component, where the user can play a video in a Flex Spark VideoDisplay. There will be a button and whenever the button is pressed, I want to save the current time of the VideoDisplay plus a screenshot. The screenshot needs to be someway saved, because I want to display all times and screenshots in a DataGrid (screenshots should appear when the user hovers a time in the DataGrid). So, how can I take screenshots of the Spark VideoDisplay and save/display them?

For a schoolassigment me and some buddies of mine are creating an application that is showing many similarities with the C-Mon & Kypski musicvideo on [URL]. The application is being developed in Flex.
We want to get a random point of a clip, let it pause so a user can mimic the pose and make a snapshot out of it.
What i managed to do is get a random point of the movie. I did this by getting a random value between 0 and de total duration of the movie.
But what i didn't managed to do is let the screen pause on every 24st of a frame. As the movie concist out of 24FPS. It looks like the the random value of the movie that is being requested is being rounded by the movie itself. As example: There appears to be no difference between the frames requested at 2.40 or 2.41.
It appears it got something to do with keyframing i've read on the Adobe® Flex™ 3.5 Language Reference. The movie is a FLV file and i use the VideoDisplay object to display the movie.

I have noticed that I have to put flv files in the same or sub-directories of the application file, for example myproject/bin-debug/flvs/1.flv, and use videodisplay.source="flvs/1.flv" to load.
If I put it in myproject/flvs/1.flv, I cannot load it in VideoDisplay, using videodisplay.source="../flvs/1.flv". However the metadata (duration for example) is retrieved, but play() cannot start it.

I'm trying to make VideoDisplay playing media with FlashDevelop. Here's the source of my application:
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="[URL]">
<mx:Script>
<![CDATA[
import mx.events.VideoEvent;
private function pause():void {
[Code] .....
The problem is when I build application and run it (unfortunately, got no idea how to run it without KMPlayer or Mozilla - Flash Player is a plugin afaik) I got no video. The movie file is in the same directory as application's "Application.flv" one. But if I reload application (within player or browser) a few times, video starts. So, here are my questions: What's wrong with VideoDisplay component and how to fix this 'non-playing'? What's the better way to execute application than running it within movie player or browser?

how to receive an event when the streams disconnects that would be great.
The documentation for this control is simply horrible. I have an application that will have a live video stream and I'm looking for a way to make the VideoDisplay control restore its connection in case of the occurrence of any of these specific scenarios:
The application starts and the stream is not online yet. The application is streaming and the user is disconnected from the internet. The application is streaming and the video server crashes and reboots.
I'm using Wowza Media Server and Wirecast to test this. 1 and 3 don't work, I'm not sure number 2 does. I made number 1 work by adding this very questionable piece of code:

I'm currently building an air app with FB 4.
I have a custom control that contains a VideoDisplay control, and which loaded using the PopupManager.
Using the profiler, i've noticed that every time the my popup is loaded the memory for it gets allocated, but when it's closed the memory is never recovered.
There's nothing else holding a reference to the popup. And if I don't set the source of the VideoDisplay object, then there is no leak - but as soon as the source is set I get a leak.
I can't see any method to force close the stream or anything on the spark VideoDisplay control.
EDIT: I have tried setting the source to null before closing the popup but that doesn't change anything.
Also, I'm not holding any event listener to the video.
Edit 2: It doesn't happen if I replace the spark VideoDisplay with an mx VideoDisplay. Bug in the spark component?

I'm using Flash Builder and created a spark-application Flex project that will stream video from the local camera. If I use mx.controls.VideoDisplay; there is no problem since it has attachCamera(camera) method. But Spark's VideoDisplay component does not have that method. I know I can use mx controls inside a Spark app but I want to know:
What is the real difference between spark.components.VideoDisplay and mx.controls.VideoDisplay?How do I attach camera to spark. components.VideoDisplay?Is there any advantages if I go with spark (since it's newer to mx library)?
EDIT: In the documentation this is mentioned: "Starting with Flex 4.0, Adobe recommends that you use the spark.components.VideoPlayer class as an alternative to this class. (mx.controls.VideoDisplay)"

I have a VideoDisplay instance playing some video. When I click on the video slider (also my component) the property videoDisplay.playheadTime is set and the videoDisplay.state goes from 'playing' into a 'seeking' state for a brief moment (the videoDisplay seeks for a new position and then plays the video again). Intended bevaiour. But if I'm (or any random user) fast enough, I can set the playheadTime again while the player is still in 'seeking' state. When repeated several times every click is enqueued and the videoDisplay jump on every place of the video I have clicked(this is happening in an interval about 10-15 second after my last click). When I use live dragging the videoDisplay, overwhelmed by seekings, goes into 'error' state.My question is - is there any way to cancel seeking state of the VideoDisplay class? For example player is in 'seeking' state, I set playheadTime, and the player forgets about last seeking and try to find the new place of the video.

I want to also add cuepoints to a live recording video as it is incoming.
I have a live feed incoming from a VideoDisplay object in my Flex Air app, and I would like to be able to record the video/audio of this and save it to disk and/or upload to server.
Is this possible? If so, would it be possible to add CuePoints to the video as it is being streamed live? Right now I am just trying to record a live stream from my VideoDisplay.

I am passing to the source property of a VideoDisplay component a DynamicStreamingVideoSource object with 3 different dynamic live stream items, described by this XML, for your consideration:
src="rtmp://88.87.56.214:1935/live/fashiontv_tmo_h.stream" bitrate="19200"
src="rtmp://88.87.56.214:1935/live/fashiontv_tmo_m.stream" bitrate="9000"
src="rtmp://88.87.56.214:1935/live/fashiontv_tmo_l.stream" bitrate="3600"
But the player then runs the stream with the lowest bitrate, out of those 3. Wasn't it supposed to go for the stream with the highest bitrate, that is viewable by the end-user? All 3 streams have been individually tested and they are all viewable.

I'm using Flex 3 VideoDisplay class for playing streaming video. When I drag the track slider(change the playheadTime) there are no preview frames even if that part of the video is already loaded.
Is there anything I can do to enable this feature (from the configuration of media server or in the Flex client)?
