ActionScript 3.0 :: Track Audio And Video Buffering?
May 26, 2011
I'm working on the development of a tool that plays two audio files and one video file simutaneously.All the files need to play together at the exact same time, so that the audio syncs with the video.
Our situation right now is that each one of the files start playing at different times depending on how fast they are loading. The problem is, my programmer is telling me that there is no way to track the buffer of the audio, so for example, the video only starts playing when at least 30% of the audio is loaded. Is it possible to do this?
The video player would then display something like:
making a simple game with video stills matching a running audio track.my audio is an MP3 i built in GarageBand. all works well in flash, but when rendered to QT, the audio and video go out of sync, and some video drops out too.have put all audios on their own layer and streamed them all too, set settings in Publish to 64, but still have same problem
I've got the next track to load, when the first one is done, and after that everything works fine.I'm trying to make it so that two tracks will buffer in the same manner - but feel like I'm doing things the hard way.....http:[url]....that is the code
and
http:[url]....that is the fla, txt, and audio files.
I have written a little MP3 streaming player. Nothing big. But on some file, it takes longer to fill enough of the buffer before starting to play. My construct is fairly simple...
var player:Sound = new Sound(); player.onLoad = function(success:Boolean):Void { if (success) { // do something; }} player.loadSound(musicURL,true);
Since I have specified streaming, this will auto play as soon as the buffer is full. What I'd like to do is play a little animation or something while the buffer is filling so the user won't think the player has hung.
I have a music player playing a live radio stream. Everytime the player loads the radio stream, it has a stutter start and then it buffers for a few seconds (how long depends on your internet connection speed) and then it continues playing. I want a buffering icon to appear during this brief buffering period. Watching the sound.position, I see that its increasing pauses at approximately the 0.4 second mark when the stream buffers.
When buffering finished it continues counting up to infinity as the stream plays. I thought maybe it would be possible to write an IF statement saying if the current sound.position is equal to what it was a second or split-second ago (i.e., it's not increasing, the stream is stopped for buffering), display the buffering icon. But I don't know how to write this IF statement.
As I understand it video over a connection of say 40Kb/s wont actually have time to load and make a buffer, and it'll be "glitchy", so it wont make much difference whatever buffering is put in place. I'm getting complaints about glitchy video. I don't have access to the servers serving the media so I put a load timer in a swf along the lines of averageLoadSpeed = (bytesLoaded / loadTimer.currentCount) / 1024;
Out of 5 tests run, 2 were below 50Kb/s. And I've been told the server also is not geared towards media and put priorities on other business tasks. The head of IT for this company keeps going at me about buffering, and how that'll fix the problem. I tried to explain that the speed is way too low (32Mb = 32768Kb / 24Kb/s = 1,365 seconds * 60 = 22min) enlighten me on buffering aside from wikipedia's explanation about IO streams.
I am developing the video player with custom video controls and I want to stop the video buffering when my video is paused. As sson as I play the video the buffering starts from the last bufferring point.
The buttons on the page cause a jump to the individual movies (the web pages) which are on one layer concurrently. What I have right now works and now I want to add audio. The intent is to have a song start when the viewer connects to the website and will have controls to stop it if they wish. I added a layer that contains the audio which works OK but clicking the Home button causes the audio to play again resulting more than one audio track. I was able to fix that by starting the Home movie one frame later than the audio but I don't really think this is the right approach. Is the method I'm using for the audio correct (see screenshot) or is there a better way to do it? I need to control the audio independently with affecting the other layers. The music track will be in the Sound layer. I had to remove it because the song hasn't been released yet.The attached FLA is saved in CS3 but I am working in CS4.
I would like to continuously loop an audio track which is being played, meaning I would like to click the button once have the track continue to play over and over again. This is the code I have so far which allows me to click the button and for the track to play only once.
var mysound:Sound = new Sound(); var mychannel:SoundChannel; var myrequest:URLRequest=new URLRequest("drums.mp3"); mysound.load(myrequest);
So I have an mp3 file. I have some frames inserted. Now I Need to insert this track as flv sound. How to du such thing (for frames insert I use this class [URL]
We are creating a 30-track mixing desk to demonstrate our percussion instruments. Take a look at www.bellpercmixer.com. As you can probably hear, the audio is not properly syncing up.
The files should be exactly the same length (8 seconds) but they are mp3s so I don't know if the compression messes the length up as I know it adds the gap between the loop? More than likely, it is my lack of action script skill that has caused this problem... e.g. does each track need to be on a separate layer with a sync-track type thing? Here is an example of the script:
How would I pause the audio track in flash?I am creating a little movie and would like to pause the commentary (soundtrack) so I can show more pictures.
I had to create a flash file which has animations, an audio track and at the end a set of html links.
The flash file to have stop and play buttons. Correct me if I'm wrong but to do this I would have to render the flash file as an mov, convert that to an flv and import the flv into a new flash file and use THAT swf which will contain the playback component of my choice.
If so Now, the problem is how can I get the links at the end of the file to work as when I convert to mov the actionscript is no longer working.
I was curious as to how I can make an audio player with a track bar, play, pause, stop, and volume slider. Most of the tutorials or free download files I find don't have all of these features.
I have a xml video background and need to add a preloader before the video is buffering. The problem is that I am loading the video from xml file and from what I've tried the preloader works for the swf file but not for f4v video loaded externally. You can check the preview here: [URL]. What I've come with is to compress the video so Ill get a smaller file or change the buffer time, but the priority is to come out with the preloader.
my question today deals with Flash AS3 video buffering. (Streaming or Progressive) I want to be able to detect when the video is being buffered, so I can display some sort of animation letting the user know to wait just a little longer.
Currently my video will start up, hold on frame 1 for 3-4 secs then play. Kinda giving the impression that the video is paused or broken :(
Update
NetStatusEvent from livedocs. It seems to me that the key status to be working in is "NetStream.Buffer.Empty" so I added some code in there to see if this would trigger my animation or a trace statement. No luck yet, however when the Buffer is full it will trigger my code :/ Maybe my video is always somewhere between Buffer.Empty and Buffer.Full that's why it won't trigger any code when I test case for Buffer.Empty?
public function netStatusHandler(event:NetStatusEvent):void { // handles net status events
I'm new to Flex and currently working on the Video Component in Flex. The problem is:Buffering starts only after the specified time. So, if i have specified the Buffer Time to be 2 s, then the video buffers for sometime, gets the data for the 2s and then plays it and then again buffers. The point is it is not buffering in parallel to playing. Is there any way of making this possible in Flex 3? Or is it already there in newer versions of Flex?
I have some videos that are already in FLV format. I embedded them inside a little swf. And I embedded that swf into a bigger swf where everything els is. When a user clicks on a button, it loads the swf with the FLV movie in it...how would you go about buffering a video?
When my streaming videos start they will buffer and begin to play as normal. However, as soon as the vid starts buffering again a problem arises. Basically what is happening is that Flash is buffering the video to a certain point, but instead of resuming playback from the point where the vid paused it now jumps instantly to the end of the newly buffered area without playing the vid portion in between. Which essentially means that it skips merrily through the video and never stops buffering.
I am pretty new to scripting and Flash and streaming vid is proving a massive headache at the mo. Have bashed through most of my problems but this one has got me stumped, scripting skills not up to the task. When my streaming videos start they will buffer and begin to play as normal. However, as soon as the vid starts buffering again a problem arises. Basically what is happening is that Flash is buffering the video to a certain point, but instead of resuming playback from the point where the vid paused it now jumps instantly to the end of the newly buffered area without playing the vid portion in between. Which essentially means that it skips merrily through the video and never stops buffering. That said I'd prefer to get to the root of the prob, particularly if this is a codec/keyframe issue, since I could then re-export the vids appropriately. I am using mpg4 (.mov) with H264 compression and keyframes at 1 sec intervals.
I've been working on a video-centric project that requires a very specifically designed video player, which I've built from scratch -- no skin. Things were going great until I actually uploaded the video and SWF to my server and tried it out. Here's the issue: The video, which is an F4V that's been imported into Flash as an external asset -- I'm not using NetStream, nor am I using a Flash media server -- starts loading almost immediately. But when you use the custom-built scrubber bar to jump ahead in the video, it freezes up until, I presume, the video has loaded to that point, at which time the video starts again. If you open the SWF and let it sit for a few minutes, this isn't an issue -- you can jump back and forth as much as you want.
So clearly the problem here is that the video is loading from the beginning and the user can only get to a certain frame when that frame has already been loaded. But it must be possible to start loading from a specified point, right? After all, the video doesn't load all together and become available only when the whole thing is done. It starts loading at 0:00 and continues progressively. I just want to change where it starts loading by telling it not only to play at that point but to start loading at that point, too.
tutorial for making a buffering video player, with scrubber etc that lets the viewer see how much of the video has loaded whilst they watch it. I've been searching for ages but to of no avail!I'm using MX, not MX 2004
Any dynamic buffering strategy solution for streaming video from the FMS server? I am following the Adobe Tutorial but i get confused where to place all of the files as I am not using the Management Console...I'm using flv hosting and all i have access to is just the ftp servers.
I have downloaded and installed the Flash Media Server (FMS) trial version. Just purchased the software today and waiting for the activation serial number. I created a video gallery - [URL]. My goal is for these videos to stream just like vimeo. I am only using HD 1280 x 720 video. All videos are between 25 to 125 MB in size, originally .mov files converted to .flv using FFMPEG. Videos are between 30 seconds to 58 seconds in length.
I am using ColdFusion to upload and organize my videos and I have configured FMS to work with CF. The Issue is that these videos buffer the same way they did when I didn't have FMS installed. Press play, the video buffers, the video plays, then stops to buffer again. Stop and Buffer, Stop and Buffer. I can understand if there is buffering at the start of the video but not throughout. When I start the video over from the start, it has to buffer all over again!
I got myself an assignment which requires me to add buffering and few other video related functions to a flash file that uses embedded video( on the timeline).
this swf is about 30-40Mb in size and it loads quite a while.
what i need to do is to detect when the video stops playing, runs out of buffer, but i dont know how do i listen to the netstream events if there is no netstream on embedded video.
What is technical difference between buffering and loading ? Say, i have a video, which is showing loader bar in progress. Then what's happening exactly ? Buffering or Loading ?
I am trying to use Flex Video Display as a preview player. The player is streaming the video from the server.While The buffering is not complete, if we try to drag the play head to an area beyond buffered region, the player will drag the playhead back to the current playing position. I need to implement the player like you tube video player which allows to drag to anywhere in the track even when data is not fully buffered.Is there a way for doing this.
