ActionScript 3.0 :: FLV Video/audio Get Out Of Synch?
Sep 5, 2008
I have a video that consists of an imported FLV to thetimeline so I could put a new background behind the alpha-channeledbackground of the movie and put other thingsin front of it. When Iexport as SWF it plays just great. However, the download is akiller over DSL speed connection, so I thought I'd try making thefinished product into an FLV. To do that I have to export as QTmovie first, then from QT Pro export to FLV. It loads much quicker,however the movie's video and audio get out of synch by the firstminute (it's 4 1/2 minutes long), and by the end it looks terrible.

My movie is five about minutes long with audio and an offscreen timeline move clip containing action script to control other movie clips or play the root directory. After about a minute or so, movie clips get out-of-synch with the audio, apparently its getting bogged down. My swf file doesn't seem that big, about 2.2MB and my move clips aren't that complex, although up to three levels deep.

I have swfs for every letter of the alphabet containing a story and a song. And one swf as a loader for each letter as requested from a menu. These are then published into html.
Every file is working as normal individually and when loaded in the loader swf.
But when viewed in a browser the audio karaoke for the letter I is out of synch. and only the letter I. this happens locally and online.
The I.swf file individually and when opened in loader swf work fine. Its only happening when viewed with a browser (IE and Firefox)
all the audio are mp3 loaded from external files. But Ie also tried placing the audio in the swf timeline but the same problem occurred.
A co-worker thought it might be the file size or bit-rate of the mp3 but thats not the case because all the audio files are the same compression and bitrate The file size of the audio or the swf are not the largest in the collection either. So this rules out swf/mp3 file size and or mp3 settings.[FONT="] Im really stumped by this, because every other letter works fine, and as far as I can see they are all the same settings.

I'm using narrator clips (imported mp3 files) that I place every so often, set to Stream (as opposed to Event). This works fine, as usual.That is, UNTIL I use a "Next" or "Back" button I've implemented to go to the next section of the program. I'm using a simple gotoAndPlay("Slide"+myCurrentSlide); where "Slide" is the first part of the frame label, and myCurrentSlide is a number that increments as the movie progresses.
When the user clicks the Next button, the flash movie successfully moves ahead to the proper frame on the timeline, but the audio is out of synch, (comes in half way through a sentence, even though the frame label is placed in between mp3 files on the timeline.

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 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.

I built a timeline based player with 2 menus and many videos that you can play.The buttons move the timeline to a frame label and the video plays. The back button has a stop function built in it so the video stops playing when its hit.It plays wonderfully locally but once on a server after a few clicks it boggs down and sometimes the audio from the last video remains playing even when prompted to stop. I was pointed to use the add and remove child functions to prevent this but being very new to Flash and 100% self taught i have zero idea on how to do this. The link to the player is[url]....Even if its a link to a tutorial or something.

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 have created a bouncing logo (similar to a screensaver). The MC loops and I have added some motion trail using dupe mc's, however when the main MC loops back to the start, the motion trail seems to go out of synch and fall behind in its positioning. I have attached the FLA to show you what I mean and you can see the AS that I have used.

I'm working in Flash CS3. My animation is about a minute long, with a single audio track that plays from beginning to end. The sound quality is noticably better when I set the synching to Event, but unless I set it to Stream the sound falls behind the animation. Is there any way to maintain proper synchronization with the Event setting? Also: will the lag be consistent on different machines and players? I thought about adjusting the timing of the animation so that it matches the Event-set sound in playback, but that's such a clunky a solution it seems likely to cause other problems.

I have a 5 minute flash movie that has great sound synchronization with the motion when I export as a SWF. However, when I export as a Quicktime file (.mov), sometimes the sound is ahead of the image. Is there a setting I can tweak during Export to remedy this? (so far I have tried to save the Video as "H.264" as well as "Animation". And for sound I have had no luck with the setting of "None" or "Apple Lossless."

this one is really doing my head in and any advice (even vague thoughts) would be really great.I have an FLVPlayback component on the stage and I am loading 8 FLVs in to 8 separate video players within it. I then play the first one and when it ends I randomly select which to play next.Everything seems to work fine except that each time I run it one or two of the clips play back with only audio only and no video. It is not the same clip each time but whichever one it is will consistently fail to playback untill I re publish when it chooses a differrent clip to fail on.I am publishing for FP8 from CS4 on a Mac and it fails when I test movie as well as in FF and Safari.
If anyone has any ideas on this at all please shout them out or I am heading for the forrest never to return

I am trying to use some streaming video and audio inside my flash movie, but can't quite figure it out..I have the video saved as an FLV file, and this file was uploaded into my streaming folder on my server. I tried to use a sample player I found, and everything should add up, but nothing is coming through. How exactly am I supposed to do this, and does anyone have a sample video controller/viewer I could borrow to test this out?

I have a video on my site (progressive download, flv file, imported using flash cs3 video encoder) and I used the FLVPlayback component with a simple skin. The video works great, my only problem is that I want the sound to stop when I click on other buttons on the page. The way I designed the site (maybe not a great set up) everything is in one big swf file, so when you click on another button on the page to show another project, the sound from the video file (that is no longer showing) is still playing.URL...

I am trying to control the audio of an embedded video from a mute button. I can get the audio to play and the mute button to control the volume using the following script:
var my_nc:NetConnection=new NetConnection();
my_nc.connect(null);
var my_ns:NetStream=new NetStream(my_nc);
[code]....
The problem I am having with this is that the video is not appearing on the stage and when I place it on the stage the audio is playing twice. how I can get it to appear on the stage and still control the sound as the button is doing at the moment?
