Flash10 :: Browser Crashes - Ocx Camera Enumeration Bug?
Oct 10, 2009
I have been working on DirectShow source filters. The flash10c.ocx routine that is invoked when you click on any "Featured Highlight" on http://www.ustream.tv can abort and takes ANY browser with it under certain conditions.
After days of work, I have finally narrowed this down to the camera enumeration function(s) in flash10c.ocx. Before beginning this quest, I had no idea that the flash player was enumerating cameras on user's machines.
If you right click on a window playing flash video, and select "Settings" then click on the camera symbol, you will see a drop-down window listing all Direct-Show Source Filters that are on your machine. I have several.
Had FF4.0.12 then your forum told me to try FF3.6.17. Just made problems worse. Downloaded updates 5 days ago to Adobe and Firefox and things went haywire. Computer hangs-must do hard reboot. Could not maneuver on Facebook-hangs, cursor hangs, kicked out of games. Now cannot get into any of my games. I need to know if they are going to work together. Is there something I need to do? Another plugin I should be using?
For some reason IE 8 crashes when I try to run my flash app that has video chatting. I've traced it out to Camera.setCamera() that crashes the browser. Firefox works fine. This is a pretty urgent problem, deadlines are looming.
I've got an animated banner for my site which I've grown quite attached to. It's a scene of the sky with the Title of my site on it and there are clouds that move constantly across it.Now the tricky part and part that I think might be freezing up the browser (firefox) is that the background changes depending on your computers time.So if you visit my site and the time is past 6:00PM, the day background will change to night.It's not an instant change though. You actually have to refresh to get it to change. Anyway, if I let the site/banner sit in my browser as either the active tab or the non-active tab for at least 10 minutes, the whole browser will freeze up. The only way to stop it from freezing up is to close it and restart it.I don't know what I did wrong, but I was hoping you guys could tell me. The file size is not that big (262kb). The images were converted from .jpg to vector, so I can't see why it'd be too graphic intensive. Basically I'd just like to be able to run it at the current resolution and quality, but not have it crash people's browsers.
I need a nudge in the right direction for a theory of a solution to the below problem.
Desired Result:
Current existing structure: FLEX RIA that communicates with MySQl DB via PHP.
We basically, have a RIA that is part of a software solution we provide to our customers, we want to restrict login sessions to one/username, which we did successfully by setting a value in our MySQL DB...the point of this was to restrict the use of username(s) to one application access point and create the ability for us to charge for additional usernames, if so desired by our customer.
Problem:
Although, we successfully restricted user logins to one session, we ran into a problem when the RIA connection with the DB was inadequately terminated (eg., browser crash, OS crash, flash player error, etc). When these crashes happenned the value that was set in the DB for the user, showing them logged in, would persist and thusly lock them out of our software application. We would have to go into the database and manually reset their logged in status.
My swf is occasionally crashing the browser (or just crashing the plugin as chrome tells me).
How do I diagnose the bug? I am developing for flash player 9 using flex. The bug lies somewhere in my as3 code.
Things I have tried: Turned on log files so I can see trace("...") output. However, my log files, and my swf, are ending at inconsistent termination points. Install the debug version of the flash player Tried different browsers (today I am on vista, and can reproduce the bug on four browsers).
I am hoping there is a [legible] stack trace from the plugin.
In Actionscript 3, I make a call to Javascript using:
ExternalInterface.call('javascriptFunction');
If in Javascript, there's an error or a blocking call, the entire browser will freeze. I can't use Firebug in Firefox to debug it because the act of stepping through the callback also crashes the browser. How do I go about debugging this?
[Code]...
I'm on an HP desktop with Windows 7, Firefox 5.0, IE9, and Chrome 12.0.742.122. Either alert call will randomly cause Firefox to freeze...it actually usually happens in bunches, where it'll freeze for a few times continuously (obviously restarting Firefox each time)..and then stop for a few hours and be alright.It has yet to crash IE9 or Chrome, though I haven't tested it as extensively with Chrome. Using the Firefox console doesn't help since Firefox just crashes all together. If anyone could shed some light on that, that'd be great!
We are experiences a phenomena that flash clients connecting to a live (pre recoreded)stream served from FMS (we use 3.5.2), have their buffer grow out of proportionit is alsoccompanied mostly with a complete video freeze, until the browser crashes.(you can expect a crash after having more then 4000 seconds of video buffer active in memory)The more we switch streams via a playlist,the more this seems to happen,Thus, streaming long video feeds keeps the system stable, but when injectingfeeds into a main stream and switching back increases the probability
I'm trying to debug my flash application and when I build and run it in debug(in FlashDevelop), it crashes. Is there a dump file which can give me information about what caused the crash?
I have a client who has a home page that I built for him. Basically there are words randomly displayed in the background. Then there are three images that rotate based on a timer. So I have two timers going. I have event listeners added to the images when the app starts. I'm moving the image off the stage when it's not visible. So I'm not adding and removing listeners over and over. However, if you watch the browser memory usage in all three major browsers it climbs several mb's in a minute. Therefore, if the user sits on the homepage the browser crashes.
I'm building an Flex 4 application using IntelliJ IDEA 9.0.2 generated sample Flex application. I replace the generated mxml with the following code from the book Hello Flex 4. It simply crashes the browser when I run it. It says "Waiting for [URL]..and then crashes I tried it on both FF 3.5.9 and Chrome 4.
I am having two flash applications on a same web page. Lets say one is already accessing the camera, then if i click on the second application, it will directly start using the camera. I dont want this. I need to check if any other flash application is already accessing the camera in the same web page. Let me tell you that we cant use Camera.getCamera() and check if the camera==null, this wont work, since the camera is available.
I would like to know if it is possible (more so if it is probable) that poor action script could be causing Internet Explorer to crash intermittently during use of the flash application (see attached image). IE reports this: "The following add-on was running when this problem occurred: file: Flash10a.ocx."/This crash has never happened during developing the flash application, but it has happened to the client on XP and Vista in both IE 6&7 on several computers. This is the only information they have provided to me, although I did request more information.I have seen many posts where people blame this crash on bad installs or upgrades of the flash player, but I am shying away from this because it has happened on so many computers.Is it possible that action script code causes this crash?
If so is it possible that it could be anything other than a memory leak?How much concern does everyone take to make sure they are removing references to objects and setting objects to null so that they can be garbage collected?
I'm having a problem in a couple of projects where I'm loading images and placing them on the stage, and if you click to another site while they're loading, or press the back button, or even close your browser, it throws this error:
Code: Error #2044: Unhandled IOErrorEvent:. text=Error #2036: Load Never Completed.
Then the browser crashes. This happens in both Safari and Firefox on Mac.
The code I'm using to load the images is pretty standard (I think):
Code: loader = new Loader(); loader.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, progressHandler, false, 0, true);
I am capturing camera on flex for android using air 3.1,and found that the camera is only showing the a part of of actual camera video.When i view camera using normal camera application in android galaxy tab, it shows full camera area but when i am capturing the camera in flex its showing only the center area for it.I tried using setMode to set the resolution, but its not of any use.Is there any way to get full camera area captured inside flex using camera.getCamera ?
From a Flash object, I would like to be able to detect the presence of a webcam that the user might grant access to, without actually asking the user whether they want to grant access. This is to streamline a large application that has extra features if a webcam exists — if there is a webcam, the application will present several dialogs that lead up to the normal cam-security prompt, but if the user doesn't have the hardware, I want to skip over them altogether. Requesting access to the cam before those dialogs won't make sense to the user.
It appears not to be possible to call Camera.getCamera() without the security prompt happening. Is there a workaround? (For instance, could I, perhaps, call getCamera in a hidden Flash object and inspect its return value, or does it block until the user acknowledges the security prompt?)
I have a video capture device on a machine. I have written a windows application to capture the video from this device. While capturing, if i try to broadcast using flash it does not connect. If i'm already broadcasting and then try to capture then my windows application does not get the capture pin of the device. So, flash seems to be taking the capture pin. Is there anyway to broadcast using the preview pin on the device so that i can capture using my application. Or is there way where i can split the capture pin and give one to my app and one to the broadcaster
Usually Adobe Flash applications can access any usb-webcam.I have a USB camera for microscopes which understands TWAIN and DirectShow.Is there a possibility to access the video data from this camera with flash?

Flash CS5.5 crashes when testing this movie using CTRL-ENTER a few times. Sometimes, a message warning that the Java Virtual Machine is running out of memory appears. I would like to know whether it is the FLA or my Flash installation that is corrupt.
My flash cs3 is crashing every time I try to publish a file, why? I run vista business 32 bit I didn't have problems until today,using flash cs3 for the[code]...
When trying to view the settings or start que on any .wmv (windows Media Video) file I drag into the flash video encoder, the program immediately crashes. I've tried many different WMV files from different sources, all the same outcome.
We created a flash site, which crashes on IE. It works fine on Firefox.The problem seems to happen when the swf tries to load some MP3 files, with 'Sound.loadSound' method.
I have recently purchased CS4 Design Premium. The installation of all applications went fine (no error message) and all applications work perfect except Flash CS4. On startup I see shortly the stage screen and then the spinning beach ball. I tried uninstalling and reinstalling Flash only with no luck. I then uninstalled and reinstalled the complete Suite and still no luck. I work on a MacPro with 10.5.7. All other system requirements are fullfilled
I've been using Flash CS4 on my MAC running 10.5 for over 6 months with no issues. But now when I open a fla file it opens but when I click anywhere it will crash within seconds. I've restarted my computer and checked that my Flash App is up to date.
When I open the Flash CS4 application, it starts up fine. If I select create new flash file, the entire application crashes. That's as far as I can get. I've made all of the recent updates that I can - it's flash version 10.0.2 ... I'm running OSX v10.4.11
I've tried restarting, that doesn't do anything. I've also tried starting up Flash with nothing else open. Haven't re-installed the entire thing yet (probably what I'll do next).
just recently upgraded to Leopard. Flash now crashes when opening certain fla's (that worked fine before). The files sometimes open, but then crash the app when I select something on the stage. In these cases I can actually edit the actionscripts.I'm not sure if the crashes are related to Leopard; don't remember if I tried opening one of the problem files since upgrading.I'm on a MacBook Pro 17 2.33, 2gb ram.I repaired permissions (several times), ran various Onyx processes, zapped pram, removed all the prefs files I could find, and reinstalled the whole suite (CS3 Master suite). Bridge won't even open; it crashes on opening.
I'm trying to sort some arrays with the sortOn() function in Flash CS3.. but it always seems to crash itself upon exporting!Do you guys get this too? And is there a way to get around this?
