I am building an app in flash cs6 that is very video based... I am using a lot of videos and images....now When I debug it I get 68 mb of file size and in task manager it uses from 70 mb to - 150 mb of ram which is a lot... can anybody give me any suggestions help on how to better memory manage the app....I have a lot of stuff embedded
these are the things I am already doing..
I am using FLV videos at 1024 * 768 there are about 15-20 of the videos and each is about 1 mb to - 6 mb each
I am using addChld and removeChild so each time a video finishes playing I get rid of it..i also remove its even listeners
-I am using all png images
I am also removing sounds after they finish playing
Try it on youre device it may take less ram.

I want to load a ludicrous, binary glTF object with only a few polygons (~250), and a huge texture of size 10,000 x 5,500 pixels. The file is "only" 20MB in size.
When I load it using Three.js, Chrome hangs in its entirety for nearly 15 seconds. When looking in the profiler, pretty much nothing is going on during the freezing time.
If you want to load the file yourself, you can download it at https://phychi.com/uni/threejs/models/freezing-monster.glb, and the whole scene can be visited at https://phychi.com/uni/threejs/ (until I've found a solution or given up).
The behavior stays the same, whether I call GLTFLoader.load(), GLTFLoader.loadAsync(), or create my own Promise, and call .then(addToScene), without any awaits.
Does somebody have a magical solution? Or if not, how could I profile it more efficiently, seeing the internal calls? Or should I just open a bug report for Chrome/Three.js?

The issue should be resolved by upgrading the library to r135(the current release).
The releases r133 and r134 have a change that introduced a performance regression on Windows when using sRGB encoded textures.
My project on flash CS4 is getting larger, the .fla file is 55 MB and the .swf is 30 MB, I am now trying to export my movie or test it, neither of that works now, I am completely unable to run my project, help!?
does flash cs4 has limits to what it can handle in one movie?
If it is a memory problem, can I increase the memory allocated for flash to run or test movie?
Flash Audio Player: I have an audio file which is 6 hours long, i am not able to seek audio beyond (03:22:54) is there is memory limitation to seek play beyond this 12173943 milliseconds?
Apparently, some kind of limitation exists. AS3 fails to seek past 12173943 milliseconds, while AS2 does seek past this point, but with less precision. See this question on SO for further details. I'm not aware of any workaround barring splitting the file into chunks smaller than 12000 seconds.
I'm running a Video Recorder application (written in ActionScript 3.0) from my local machine. It records using a Red5 server which is installed on a remote Amazon EC2 server.
To record, I'm using the following settings
Width, height and FPS (for Camera.setMode()) - 1920 x 1080 and 10
Bandwidth and Quality (for Camera.setQuality()) - 0 and 80
Buffer time (for NetStream.setQuality()) - 3600
I'm able to record video till the buffer gets filled (I'm monitoring the NetStream.BufferLength constantly)
Once, the recording is stopped - the data in the buffer is sent to the server. And now, when I try to playback with (bufferTime = 1) The video doesn't appear.
I have ssh 'ed into the EC2 server and have seen that the file does get created in the red5/webapps/vod/streams folder, but I'm am unsure about its quality or whether it has recorded correctly or not. I've even used the command line based movie player mplayer to try and play the file, but it doesn't play because I'm guessing the Ec2 server Ubuntu lacks the playback plugins (not sure of this though.)
However, when it's a low quality recording with 640 x 480 instead of 1920 x 1080, the buffer doesn't get filled beyond 0.1 or 0.2, and the video plays back smoothly.
My Internet upload speed is around 300 kbps.
How can I (if it is possible), record and then playback high quality video?
You need to use
// Ensure that no more than 43690.6(43K/second) is used to send video.
camera.setQuality(43690.6,0);
This works for me. I used Amazon EC2 extra large instance.
Your issue stems from these 3 causes happening simultaneously:
recording high quality video which results in the data having to be buffered locally
Flash Player buffering just the video data (good for when doing live streaming)
Red5's buggy mechanism for dealing with video data coming at the end of the recording
Red5 has been plagued by many recording issues. This HDFVR documentation article covers Red5's various recording issues and the mechanism for coping with the FP buffer when recording over slow connections.
The media server needs to account for this by waiting more for the video packets and sort them together with the audio packets before writing the data to disk (.flv file).
Red5 0.8 had no such mechanism thus recording high quality video over slow connections resulted in low quality/scrambled video files (just audio, all video at the end).
Red5 0.9 had audio video recording totally broken.
Red5 1.0 RC1 had a new delayed write mechanism - controlled by in Red5/conf/red5-common.xml - that waits for the audio and video data and rearranges the packets before writing them to disk. The queueThreshold value measures rtmp messages/packets.
Red5 1.0 final, 1.0.1 and 1.0.2 had the delayed write mechanism totally broken. With it turned on, over slow connections, Red5 was producing .flv files with only 1 or 2 video keyframes. When playing back such .flv files the video would get stuck from the 1st second and playback would continue only with audio. Using yamdi to extract the keyframe data confirmed that the .flv files were lacking video keyframes.
However, thanks to HDFVR's code contributions to Red5, Red5 1.0.3 and later has video recording over slow connections fixed.
I'm recording video from a webcam with Flash, saving it on an Adobe (Flash) Media Server
What are all the things that can contribute to a choppy video full of missing frames? What do I need to adjust to fix this, or what can contribute to the problem?
The server is an Amazon Web Services Medium (M1) EC2 instance. 2 ghz processor, with 3.75gb RAM Looking on the admin console for AMS, The server is never getting maxed out in terms of RAM or CPU percentage
Bandwidth is never over 4mb.
The flash recorder captures at 320x240 at 15fps
I used setQuality(0,100) on the camera. I can still make out individual "pixels" when viewing my recording, but it isn't bad
Server has nothing to do with this. If the computer running the Flash file can't keep up, then you get dropped frames. You basically have 1000/stage.framerate ms to run every calculation for every frame. If your application is running at 30 fps, that is roughly 33ms per frame. You need to make sure everything that needs to happen on each frame can run in that amount of time, which is obviously difficult/impossible to do with the wide range of hardware out there.
Additionally, 15fps itself is too low. The low-end threshhold for what the human eye can perceive as motion is around 24 fps. So at 15fps, you will notice choppiness. Ideally, you want to record at 30fps, which is near the is about where the human eye stops being able to distinguish individual frames.
