ActionScript 3.0 :: Audio Hits During The Video Scrub
Jun 29, 2011
I've made a video scrubber for a couple of external F4Vs in my movie. I'm using 2 setIntervals for the scrub function: 1 to move my video playhead as the video plays, and 2 to seek to the correct video frame as the user drags the playhead.
This seems to be working ok. I wish it was a little bit more fluid in the scrub action, but I'll take what I can at this point.
But, one thing I'd like to work on is the audio hits during the video scrub. As the netstream seek is happening, the audio is hitting while I scrub. I'd like to temporarily kill the audio as I scrub, and then bring it back on at the MOUSE_UP.
I'm pretty sure that SoundMixer.stopAll(); will get rid of my audio, but what will make it come back?
I was wondering if anyone could help me get some information on audio limitations in flash. Is it possible to have audio "scrubbing" that allows you to hear the audio as you scrub? Currently the only way I know to do this is by having it on the timeline, and set to stream. Using this method seems to be causing more issues than it solves. Preferably I would just like to load the audio in dynamically and then scrub through it. Is it possible to use that method and then still retain the ability to hear it as you scrub through it?I am having with the audio on the timeline. The main issue with this is that I have to manually add frames to the timeline, in addition to that I can not dynamically load the audio through xml. Well not that I know of.I think the best route is probably loading in the audio dynamically.
are you able to scrub an mp3 sound with a slider bar? im looking through the Sound class but there appears to be no properties that would aid in that (like NetStream.time())
I'm making a working scrubber on a video, but having problems. The scrub itself it starting out in the middle of the loadbar. I've looked everywhere, trying to find out what is wrong with it.
I need to have scrub thumbs for video player load and unload repeatedly. Something isn't getting cleared. Every time the thumbs are removed, there's a slight increase in the cpu baseline - something is piling up in memory.
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.
So i found a code on the adobe site which pics up input from the mic. I need that to trigger a video when it hits a certain volume. I'm a complete novice to AS3 and i need this for a proof of concept in the morning. Here's the code that i'm using to pick up the mic -
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 a SWF movie (only animation, no Actionscript) and I would like to programatically extract the resulting video and audio and whatever resolution.
When I use the webcam and microsoft to record a video, my audio and video are out of sync.This does not happens when I use the built-in Microphone on the webcam.
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.
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
When I go to test my video the audio and video are playing at different playback speeds. I'm trying to create a video using Flash that requires events based on the song itself. how to make the audio and video play at the same speed during Timeline playback and testing?
i am new to flex. I have this task. My boss wants an application that will enable his secretary in another room listen and view and probably take minutes of his meeting in the conference room. There is a webcam attached to one of the computers in the conference room.
I'm trying to load an MP4 using CS4 and actionscript 3. The clip is loading but I'm only hearing the audio, I'm not getting any audio. Not sure what I'm missing. Here's my code it doesn't produce any errors:
Code: var nc:NetConnection = new NetConnection(); nc.connect(null); var ns:NetStream = new NetStream(nc);
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...
what i am looking for is an FLV player type component (doesn't have to be an actual component) that will play SWFs. i need it to have all the same functionality (play, pause, scrub bar, etc...) it seems crazy that there isn't one out there i have even looked in the Exchange area and only seem to find ones that control FLVs or MOVs, not SWFs.
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?
Can I use addchild & cuepoints in a streamed video to
1. play an external moviclip/swf on top layer with a transparent background? (without affecting original timeline & background video playback)
2. play an external audioclip/mp3/swf that will be "inserted" into original timeline?(thus extending original timeline however long the external audioclip is)
