if Adobe is going to implement GPU acceleration into the Flash Player (similar to what is now going on with all internet browsers and HTML5), I am not asking about acceleration of HD video which they have done with v10 of flash player but about real DirectX or Direct2D acceleration so the whole scene and all objects on it would be accelerated by graphic card.
View 2 RepliesWe run surf camera streams on our website, which are played via the latest version (5.4) of JWPlayer on our pages. Recently we switched over to another streaming service, and H.264 streams, as we are planning on streaming out to iOS devices in the very near future, however this introduced a bug on the client side where users to not receive vision (they only see a black screen where the video is normally seen).
We have discovered that disabling the Hardware Acceleration (which was introduced in Flash Player 10.1+) fixes this issue, and given the spectrum of environments where this issues is happening I would wager that this is related to specific graphics cards, their drivers, and how they handle the vision decoding etc.
The documentation we have found relating to disabling Hardware Acceleration only indicate that this can be done via the wmode param, i.e. by setting it to wmode="opaque" or wmode="transparent" however this doesn't seem to work in all cases (for the most part the issue is no longer there) however we are still seeing 30% of our users getting this issue.
We can ask the users to disable hardware acceleration themselves, and we have provided details on how to do this, however to me that is only a temporary fix, and I was curious as to whether or not there was something more permanent we can put in until Adobe fix up this issue?
I'm working for a company who is using flash to play HD media. Right now, the systems they are having to buy to play the media conent must have relatively decent CPUs in them due to flash relying mostly on the CPU. With the flash 10.1 beta there is now obviously a focus on GPU acceleration and we are quite excited about this as it could considerably drop the cost of each of our hardware units. We have tried some tests thus far however it appears that our flvs are not taking advantage of the GPU acceleration. The only way I know how to test this is by enabling/disabling the hardware acceleration from the settings menu in flash and then restart the browser to be sure the setting has changed.
I am assuming that our flv is perhaps not encoded in a format that flash will be able to use hardware acceleration for however I am not completely sure of this. The media encoding is not part of my job on this project howeve I am tasked with the testing of the flv's on carious hardware. Is there a specific codec that needs to be used or a way of encoding the flv so that flash player 10.1 beta can play the video with hardware acceleration?
I don't know the ins and outs of the encoding process that is currrently being used, but I will pass any infomation gathered here onto our media guys and developers. I do know that using the flash 10.1 beta on youtube I can play 1080p videos fullscreen using nVidia GPU and an intel atom cpu without any issues with the hardware acceleration on. WIthout it, the cpu hits 90+% and the video is way to choppy to be of use so hardware acceleration is definitely working there.
in the adobe flash publish settings i spotted a setting called "Hardware acceleration" with these options:
-None
-Level 1 - Direct
-Level 2 - GPU
now my question is, if you dont use flash to compile your swf but rather flex sdk, can you also enable these accelerations?
For a maze game, I'm trying to add acceleration to the movement of my character.Because the character shouldn't walk through walls, the movement function and hittest are in the same function.
I tried adding the acceleration in if statements in this function, but that doesn't work properly. [code]...
Is possible to check by actionscript if h.264 video playback is using hardware acceleration?
View 0 RepliesI'm toying with an Adobe Air app that plays quite large movies. I want to run it on a 1920x1080 display connected to a Mac. Unfortunately, the movies tend to stutter and I'm betting that happens because I'm not using HW GPU acceleration for H264 playback.
Most of the player code is ported (aka copied) from a web player I built and which runs very smooth on the Flash Player from the browser. So the code shouldn't be the problem.
In the Flash Player, to use GPU acceleration in a fullscreen mode, you have to set the Stage.fullscreenSourceRect property. However, this doesn't seem to work in Adobe Air...
I have a 2D side scrolling game (made with ActionScript 3) that runs at 60 frames per second. I'm trying to make it frame rate independent so it will run on slower devices.
To do this I create a var called timeElapsed by calculating how many milliseconds have passed between each frame and dividing that by 16 (60 fps is about 16ms, I think.) So that at 60 fps the result would be about 1. Then I times any time related vars by this number (e.g player.x = speed * timeElapsed;) This is the code:
private var oldTime :Number;
private var defaultFrameRate :uint = 16; // the default frame rate in milliseconds
private var timeElapsed :Number;
[Code]....
As you can see, at 30 frames per second the player is moved further in the same amount of real time. What seems to be the issue is that, at 30fps in frame one, my current code doesn't account for the slight difference in speed between frame one and two at 60fps. I thought of getting the average value of speed between any two frames at 60fps and using that to calculate a more accurate value when the frame rate changes but I got the feeling wouldn't work correctly in some other situations since at 60fps for example, it would move the player by 115 and not 110 pixels.
Is their any way to accurately simulate an object accelerating in a way that is frame rate independent?
[URL].. To enable the SWF file to use hardware acceleration, select one of the following options from the Hardware Acceleration menu: Level 1 - Direct Direct mode improves playback performance by allowing Flash Player to draw directly on the screen instead of letting the browser do the drawing. Level 2 - GPU In GPU mode, Flash Player utilizes the available computing power of the graphics card to perform video playback and compositing of layered graphics. This provides another level of performance benefit depending on the user's graphics hardware. Use this option when you expect that your audience will have high-end graphics cards. If the playback system does not have sufficient hardware to enable acceleration, Flash Player reverts to normal drawing mode automatically. For best performance on web pages containing multiple SWF files, enable hardware acceleration for only one of the SWF files. Hardware acceleration is not used in Test Movie mode. When you publish your SWF file, the HTML file that embeds it contains a wmode HTML parameter. Choosing Level 1 or Level 2 hardware acceleration sets the wmode HTML parameter to "direct" or "gpu" respectively. Turning on hardware acceleration overrides the Window Mode setting you may have chosen in the HTML tab of the Publish Settings dialog box, because it is also stored in the wmode parameter in the HTML file.
Does this mean that the newest version of Flash will support Hardware acceleration? The kind of hardware support that will produce less laggy animations and games? I've been waiting for flash to do this. I have a couple game ideas, but they're too big for flash, and well, I wasn't very inspired to learn other languages.
Is it possible to enable hardware acceleration (Level 1, Level 2) for a swf generated in Flash Builder. I don't use the Flash IDE and therefor I have no access to the "Publish Settings" in the Flash IDE? Maybe there is some compiler arguments? [URL].

In my Flash File I have a wheel. The user is able to rotate the wheel by using arrows to jump to the next "segment" (think 20 images attached to each other forming the circumference of the wheel).
[Code]...
However, what I want to be able to do is, click and drag to spin the wheel, complete with acceleration and deceleration and even settling on the nearest image when the wheel reduces to a certain speed. I have no idea how to go about doing this: I'll need to kinda detect a before and after position of the cursor and translate this into a speed for the wheel which then decelerates over time and also detect which image is closest at a certain speed and "snap" it, both scrolling up and down. (it'll only affect the Y-axis)
Has anyone found that since Flash 11 plug-in with hardware acceleration the video movie clips seem to fall apart? I see quality loss both in hardware acceleration and without in all my clips since this upgrade. Before that the movies were fine! Also I have installed a new Nvidia driver, do you think this is a issue?
I think Flash enables hardware acceleration in in-page video movies as well as full-screen mode.
Do I have to redo all my video clips now or am I just confused?

I have a swc plugin embedded in my product to stream live video to a group of recipients.The plugin uses the NetStream, NetGroup and NetConnection objects, the server I use to handle the RTMFP session is Influxis.One client creates a group as a publisher, and stream a live video.His Camera is enabled and I can see the video on the screen as well. The others connect to his group and play the video.Peer assisted Networking is enabled for both the publisher and the recipients.The plugin worked well in all 10.x versions (10.1/10.2/10.3)However, when upgrading to flash player 11.x, it stopped working.
-11.x to 11.x isn't working.
-10.x with 11.x isn't working.
-only 10.x to 10.x is working.
The server I use to handle the RTMFP protocol is Influxis.com I sent them the same question as well.The weirdest fact is that I'm using flash builder 4.6 with 4.6 sdk, which is aimed for flash player 11.1, and it is only working with 10.x flash players.
I'm having a performance problem that seem to be related to Flash Player 11.I noticed this mainly because Chrome auto-updates the flash player. So, it's now up to 11 in Chrome. During a sliding section transition, the flash player chokes and skips about 10-20 frames. In essence the content jumps, not a smooth transitions. You can see this at the following url. Using a browser with 10, plays as intended, a separate browser with 11, chokes and jumps ahead.
firstworldproblems-[url].....I have security sensitive site, that is more elaborate that I can't share here. But, the same issue is happening above.I'm using LoaderMax to load assets. Adding it to the stage and then animating them in from the left or right of the stage, using Tweenmax. The one I can't show is a series of images, 1280x640 pixels, 10 in total.Removing items from the stage when they are not visible, so I can get the CPU usage back. On Flash Player 10, this is working as intended.On 11 it jumps. I don't think it's the removing assets from the stage that's choking the player, because the above link has the same issue.I feel like this is a Flash Player 11 performance issue.

I'm building a portfolio site. I have buttons to go to previous/next frames and I have all the buttons on the timeline. Each instance is properly labeled and referenced in the actionscript. I get no errors when I publish in 9, but when published in 10 I get:
TypeError: Error #1009: Cannot access a property or method of a null object reference.
I'm not sure why this is happening because there isn't a null reference in my mind. The button which I reference in the code is on that exact same frame. I think the error is that it's looking for the button from the previous frame, which puzzles me because I've moved on to the next frame and I don't know why it'd be trying to reference that. Anyone know of DisplayObject differences from 9 to 10 that would be causing me these troubles?
I have two mp4 video files on webserver, i wanted to play them in flash player(flv player) on my asp.net page, but i couldn't be able to play them, i also tried to play them in quick time player the same prob occured. but i waz giving the accurate path, there were no spaces in mp4 file names etc. Does it need to have mp4 player(or codec etc) installed on webserver?
I have also some wmv files on that server , and i am playing perfectly using silver light player, and media player object on my website.
I am trying to make the SIMPLEST POSSIBLE MP# player using the player component preinstalled in flash.It is very simple, the code is as follows:
Code:
on (release) {
player.contentPath ="Song.mp3"
player.play()
}
("player" is the mp3 component)
This works if I want a single track to be selected and played.Now, I need it to AUTOMATICALLY LOAD THE NEXT TRACK, which I will input in the code.I am thinking something like this:
Code:
player.onSoundComplete = function() {
player.contentPath ="Song.mp3"
player.play()
};
But this is not working.
PS: I know an XML file would be the best here, but I don't want to use it. I just want to enter the next track's code inside the swf.

View 1 RepliesI am trying to put together a simple game and have been doing really well until I decided I am going to have to create a new class to handle enemies.What I have so far is a player walking around on random terrains and I am up to the point where I have placed x amount of enemies on stage at appropriate times. I have written their class which will hopefully eventually handle their behavior and it outputs simple trace("BOO!").
Where I face the problem is that I obviously would like to make these enemies follow the player to attack. But when I try to access the .x or .y attributes of the player, it throws an error: 'call to a possibly undefined property with static type Class'?I have tried accessing the .x using the following ways (where badger is my player instance and Main is my class definition within the properties of the FLA):
Main.badger.x
Main(root).badger.x
Stage.badger.x
I have also tried to access other vars and still nope..My class code is this:

on publishing some FLA files on FLASH-8, a warning pops up saying the target Flash Player "Flash Player 8"is not installed. The standard Flash Player will be used instead" Flash Player 8 has been installed together with FLASH-8 and it shows up in Currently installed programmes in Control Panel. It is marked as a rarely used programme though I run SWF every day. Another strange thing is that it used to be marked with that FLASH red icon, now it is marked with the folder icon.
Control Panel also shows Adobe Flash Player 10 ActiveX and Adobe Flash Player 10 Plugin which I do not recall to installed - probably they came as an upgrade - I wonder if they somehow screen off Flash Player 8?
