Flex :: Can't Get Good Quality Audio/video?
Apr 28, 2011
I'm creating a video chat application, and no matter what combination of amera/Microphone/NetStream properties and functions I use, I cannot get high quality video/audio. I get occasional audio latency, pixelated video, occasional frozen video and the degree of each depends on the combination of properties/functions I set/call.Others such as TokBox, TinyChat, Chat Roulette, etc. have achieved great video/audio quality with FMS, what is the secret? At least point me in the right direction, because right now I'm not impressed with FMS ability to provide a good video/audio experience.

BTW, I'm using a P2P mesh using a group specifier, not NetStream.DIRECT_CONNECTIONS.

I'm trying to record a stream from a webcam using FMS4 developer edition. The streams are recording on a linux box in .flv files. These files though have problems.
1 - The video quality is terrible. Fuzzy/blocky. Any kind of motion looks awful. Is there any way to improve this?
2 - The sound jumps/skips and goes out of time with the video.
As it is now this is useless. I am trying to make a system where a user records a short video from the camera and then I upload it to YouTube from my server. If you use Youtube's webcam page the video quality is quite acceptable and the audio is obviously in sync too, so they must know something I don't. [URL]..

I exported flv file 1360x768 with quality 2000kbps and 30fps from After Effects. When I test it(from HDD) in vlc player it palys smoothly, but when I test it in my custom flv player in complex places it starts jerking.
is there any solution to run big flv files with good quality from custom flv player?

I have a flash application in which I need to scale a MovieClip.This MovieClip contains an image (in a Loader) with a resolution of 1024x768 (which is the size of the MovieClip as well).When I want to scale this MovieClip to 80% I do:
myMovieClip.scaleX = 0.8;
myMovieClip.scaleY = 0.8;
The problem is the resulting scaled image has aliasing and is not of good quality. Is there a way to change the scaling algorithm used to get a better image?Or is there a better way to scale MovieClips? I can't rely on bitmap data because this MovieClip may contain another SWF with video for example and it must scale regardless of its internal content.

I am using Flex for displaying videos streamed using the Red5 server. Basically i have two perspectives - one who relays and one who receives the broadcast. On the Flex side, in the video display, the video quality is good but on the receiver side it appears pixelated. I can't find the cause. Does this have anything to do with Flex encoding of videos or any Red5 server settings?

I want to use a camera which is installed in my computer in a Flex AIR application I'm writing, and I have few questions regarding the quality options : Do I have any limitation on the video image quality? If my camera supports HD recording, will I be able to record in HD format via the AIR application? How can I export the recorded video in any format I want? If I want to use the same camera for shooting stills, how can I ensure (within the code) the best quality for the result pictures?

If I import an FLV video is there any way to remove the audio, put the audio into a byte array, and then re-add the audio to the flv video?

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).

I've recently become very interested in learning how to implement various audio filters in AS3. By intuitive guessing (and inspired by capacitors), I've managed to create what seems to be a 1st order high-pass filter, but I have no idea how to set its frequency (or Q) in a controlled way.

I'm trying to create a client-side web app that generates music procedurally using some user-input parameters, so I'm looking for a framework (e.g. Flash, Silverlight etc.) that has the capability to play audio at a specified pitch. Whether it is playing a WAV/MP3 file, using MIDI output, or just playing beeps doesn't really matter -- I just need something that will enable me to generate arbitrary music client-side.
I've done a bit of searching and it appears that Flash might have the ability to change pitch with the help of a third-part plugin, but I couldn't find anything similar for Silverlight.

I have a FLV playing in my SWF and when viewed locally in Flash or just in the Flash player by clicking the file on my desktop the file plays fine with decent quality audio. However as soon as I upload the file to my website the audio quality seems to drop.

I have created a FLV file using Adobe Media Encoder CS5. I have played it back on Several Media players and it sound fine. I import it into a Scene in Flash CS5 aand when I preview the Scene the audio has degraded and sounds terrible.
The audio is mono at 48 kbps. I cannot find any controls or options to edit the audio of the video. I have rendered it out several times using different settings but it alway plays back the same highly compressed tinny sound.

I have an AS3 video player I've put together using fairly standard Netstream method and it plays my flv's fine. The problem is, the sound quality varies wildly depending on who is looking at it. When I test locally, the audio in the video is fine, but on a windows machine it goes horrifically loud to the point of distortion, also the client (outside the UK) has said it sounds fine to them, so It appears to be only happening here.

I'm using flex 3. I've successfully played video and audio files by using following libraries:
flash.media.Video flash.media.Sound Live docs link. But the limitations are as follow: Video class can be used to play only flv file format. To play mp3 files I must use audio file.
So can I play most of the famous audio/video files by using single method?
Well by checking the file type we can some how achieve it. Then I should create a component for that.
So can any one suggest me such ready-made components? or is there any other alternatives to play audio/video files?

I am developing a simple application using flex which records a video with my webcam and stores it to the media server and then i pull it in order to show it.The problem is that the quality of the video played is blurry while it is displayed with the same size as captured. I have played a lot with the values in the functionsbelow where i attach my cam to the netstream objec: cam.setMode(640, 480, 25);cam.setQuality(0,90);and the result is an flv video which i play later on but with not a good quality. The server is on my pc so i dont have transfer delays because of low connection. Whatcan i do to have a better output? i use netstream play method to play the video and i do the following
video = new Video(640,480);
video.attachNetStream(ns);
video.smoothing=true;
[code].....

Looking for a component which can be embedded inside my site (PHP, ASP.NET...whatever) and give a support for video chat. I'm not a flex developer and would like to use a component. There are some/many video chats available, like flashcoms, red5chat...but all of those are heavy(monolit) components.
What I would like to have on my site is just a small video showing output from my camera (me) and another video showing the other party...but those videos should be split, not in the same flash component, but separate (two different EMBED tags on my page).
Are there any components available to do that (of course with support from appropriate media server)? Are there any good guides on how to develop such a component?

I'm writing a flex 4.5 application that's supposed to capture a video from a webcam and audio from microphone and save it in some video format (i don't care which format). I use VideoDisplay to display the webcam. how can I fetch and play audio in real time ? Is there a way to save the video locally without using a flash media server?

I ran a simple live video streaming application for the first time with actual users and ran into a couple of serious performance issues that had not turned up during testing. In this instance there was one video stream from a live web cam and used FMLE at 150 kbps using VP6 and MP3 @22k. There were 16 clients and everything worked pretty good for about 30 minutes. (although some clients said their audio and video were out of sync by up to 3 seconds)
Then individual clients would have either the video freeze or the video would continue and the audio would stop. These clints had to "disconnect" and then "connect" again to the application. This happened to all of the clients at one time or another for several minutes. I stopped and restarted the FMLE with progessively lower bandwidth settings down to 75 kbps but still clients were having the same issue.
I eventually stopped the FMLE and used the applications built in publisher at 45 kbps and that seemed to eliminate the freeze/dropping issue. But of course the video quality was very poor and some clients still reported that the audio was out of sync with the video. The server hosting the FMS application is a quad processor dell with lots of memory and network connectivity. The Flash Media Admin Console performance graph showed the total Bandwidth as 3 Mbps at maximum.

Looking for a programming book that is in tutorial approach. Example this chapter teaches you how to do a login form. In the second chapter it teaches you how to integrate the login for to another app.Basically I'm looking for a book that teaches you real working application rather than abstract ideas. Programming language I have in mind is Adobe Air/Flex, Visual Basic. Functions I have in mind should at least cover Drag and Drops, Integration to a web form (form entry) and customizable interfaces.The languages i had in mind isn't fix. If you know a programming platform that has little code or easy to learn but still be able to develop a cool application.
