ActionScript 2.0 :: FLVPlayback Does Not Display Visual Just Audio?
Dec 12, 2003
I'm working on a Flash Projector CDROM with around 10 FLVs. These FLVs are loaded dynamically into the SWF projector using actionscript from the CD. There are 10 buttons to load each movie into the same FLVPlayback instance.However, when I click the button to view/load the FLV, sometimes the video does not display but the audio can be heard playing. Furthermore this is happenning erratically and on randomly. It seems to get worse as the CD has been playing for a longer period.This sounds like an issue of Flash clogging the computer's memory. Is there a way to get around this without using a 3rd-party software like Jugglor?

creating a button within a movie clip that will pause both the images (bmps) on the screen and the sound, which is being loaded by AS3.Here's the code for my sound.
Code: //This assigns an abreviated name to the StorySongBook class which is inside the StorySongBook.mp3 properties. var sbs:StorybookSong = new StorybookSong();[code].....
How do I assign this to a button on the stage though (event listener?) and get the button to stop both audio and visual?
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 want to design a web page that will display a visual aid representing real time data. Real time for me means updating at least every few seconds, or literally realtime/event based if that is possible. The data displayed will be displayed in a rather visual/graphical way rather than simple text or a table.
I do not have a lot of knowledge of web development other than a little knowledge of HTML, so I do not know what options are available to create a web page that does what I want. My search has seemed to point towards Flash as being the technology best suited to do this, but I have also seen several articles which caution against flash (but mention no alternative).
The main alternative contender instead of Flash seems to be Comet style programming which I understand would likely utilize (in my case at least) a system called "long polling" to update data regularly. This could work, however the nature of the way I would like the information displayed leads me to believe that flash might be better than this as it sounds like longpolling is well suited for simple display of text inofrmation based on results, whereas I will need certain details of the visual display to change as well depending on results.
My research has also lead me to believe that an ASP.NET or PHP page would almost do what I want, but my understanding is that these two frameworks'/ languages' purpose is more along the lines of generation of a unique web page when loading rather than updating it as someone is looking at it.To make sure it is clear: communiciation is COMPLETELY one way in my imaginary web page. the user's display needs to update but they in no way send data back.What tools are best suited to create a webpage which will update/display (in a visual manner) data in real time in as someone is viewing it?
edit:
after finding this article: How does facebook, gmail send the real time notification?, I am thinking Comet could still be a really good option as I can just use it really as the messenger of events rather than having the direct result displayed as text or something. Still looking for advice on which way may be easier though due to my impression that Flash may be easier to program the graphics in a dynamic way.
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 have a flash program that loads an external flv dynamically. I first create an empty movie clip then I attach an instance of the FLVPlayback component using Moviclip.attachMovie();. Then i control the FLVPlayback component with AS2. I have a play and pause button, a scrubber, and a loading progress bar. None of these are components. When I publish and preview the file in Flash CS4, Adobe Flash Player 10, and all my internet browsers everything works fine, all the buttons, the multiple functions of the scrubber, and even the loading progress bar.
However when I uploaded all the files from my computer to my company's server and tested it from there, I recieved audio but no video. All of the various controls still worked for the audio but I couldn't see anything on the stage. If I waited for the loading progress bar to complete and then reloaded the external flv then I got video, but the purpose of this program is to stream the video and I cannot have the users waiting for a preloader.
If you want to look at my FLVPlayback code here it is:
I have an flvplayback component on the stage of a parent flash project. One can preview a video that has some text overlaying it that the user entered in a previous scene. Dynamic cuepoints sync the video with the overlaying text.If the viewer doesn't like the preview they can go back to the previous scene, edit the text, and rewatch/preview the video with the overlaying text to make sure they like it.
I'm running into an issue when they stop watching the video preview, they go back to the previous scene and they return to the video preview scene. I stop the video with a .stop() and I rewind it with a .seek(0) but when they return to the video player and rewatch the video there's a brief audio pop. I'm assuming the pop is a bit of video/audio left in the buffer of the flvplayback component.
My question is - is there a way or what is the best way to clear the buffer of the flvplayback component when I rewind the video so it can be replayed?Is there a better way to rewind an flvplayback to the beginning other than .stop() & seek(0) so I don't get a audio pop when it's replayed?
I create their basic Flash app with their Flash IDE for Visual Studio 2010 http:[url]....When launching the run button, it launch flash but with this error within Flash CS4: The following JavaScript error(s) occurred:
t line 6 of file "FlashApplication1.jsfl": Cannot find file file:///C:/temp/FlashApplication1/FlashApplication1/FlashApplication1.as.
I am overlooking something, but why won't my FLVPlayback component, which is in my library, be added to the display list? When the code executes, there is now FLV component on stage.[code]...
I'm trying to work with an .XML playlist. I actually need it to do a lot of things that I can't figure out how to do.. I'm sure there are tons of you out there who know exactly what to do.. [URL] I'm tried this, and it works, only I can't load album artwork using this. I also want to add a few other data fields, I would like when you click on the song title to play the audio track, but also show the Artist name, the song title, the artist record label, a link to the artists website and a short section for comments from the artist about the song. Is it possible to do something like this, using this tutorial? <song title="song" artist="artist" src="mp3s/song.mp3" /> How would I add an image to this? I want to display album artwork in the audio player.
I'm using Flash Media Server to create a 1:1 video chat. The problem I'm having is that when I use my apple cinema display I get horrible Echoing, even with the reduce echo box checked. If I don't use my cinema everything works fine with the built in macbook mic. I have to believe there is a setting as I can use iChat, Adobe Connect, WebEx, Skype all with my apple cinema and not have this MIC echoing issue.
Our Current Settings: Audio var options:MicrophoneEnhancedOptions = new MicrophoneEnhancedOptions(); options.mode = MicrophoneEnhancedMode.FULL_DUPLEX; options.echoPath = 256; options.nonLinearProcessing = true; [Code] .....
I have attached a video on a frame of my website in Flash. When I preview the movie the film plays as it should.But when I export the Fla. as a Swf. file it then doesn't have the movie there anymore?It does show this error:
**Warning** The linkage identifier 'FLVPlayback' was already assigned to the symbol 'Video/FLVPlayback', and cannot be assigned to the symbol 'FLVPlayback', since linkage identifiers must be unique.
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.
Anyone know of a skinnable audio player (or something similar to Windows Vista audio control in task bar) that i can embed in my website?
A player that can be customized to use a 'speaker' icon instead of a 'play' icon. When the speaker is clicked, the volume can be adjusted or turned off. The option of being able to autoplay and set the default volume level.
Is there not an event that occurs only when there has been some sort of visual change to an object. So for example if it were a video or animated object it would be firing as often as EnterFrame. However, if it were some sort of input control just sitting there doing nothing visually, then the event wouldn't fire until the visual state changed as a result of some sort of user input for example.
Can I use Tofino (Visual Studio plugin for Flex development) to build IOS apps? Also do I need to download the Flex 4.5 SDK if I already have Flash Builder 4.5?
In my attempt to create a simple Pong-like game, I've encountered a very strange and at times severe visual bug.When I set the ball (A Flash CS 5.5 library MovieClip) in motion moving around the screen at a rather fast speed, I've noticed that sometimes the edges of the ball would be cut-off for a short moment in the direction it is moving.
When it happens, it almost seems like the position of the ball MovieClip is slightly ahead of its own border and thus the part that is outside the border fails to get drawn.
Here's a picture that illustrates how this looks - at least for me:
You can also view the .swf file online here: [URL]
Some technical data:
I've been unsuccessful in capturing the with a screenshot no matter how much I tried. Sometimes I would open the .swf and the bug would be almost non-existent while at other times it was very blatant. I'm using an EnterFrame event function to increment / decrement the x and y position of the MovieClip. I have never encountered any such problem in any Flash app, in this machine or others. Truncating / rounding the x and y values of the MovieClip didn't help. Neither did setting cacheAsBitmap to true.
Can I build up visual communication just based on two flash client points? I mean a live video connection from a client side to another client side, without FMS.
it's been a long time since I opened VB and I just needed to make a real simple program.Someone enters their income, then based on their salary, their taxes are displayed.One input TextBox, one ouput TextBox, and a button to calculate.I'm almost there, I'm just missing something, I have a TextBox for income:
txt_income
I have a TextBox for income + taxes:
txt_taxtotal
And a Calculate button:
btn_calculate
Here is the code: (I didn't want to use a class like you did)[code].....
i know how to program in vb.net, and have little problems switching to action script. the only problem im having is that i dont know where to type my code. in visual basic there were events that you would type into. does any one who knows Vb know what im talking about? i get the whole convert to symbol stuff just not where im supposed to type
I am converting from .FLV's to .F4V. Video outputs fine but the audio sound stops after a few seconds from the beginning.I have tried many different settings for the audio with no luck. Also, tried on a colleague's machine who is running CS3, which works fine, so something is buggy in CS4...
Because the player optimizes framerate, antialiasing etc dependent on the performance capabilities of the platform upon which it is running, it was nearly impossible to ensure animation syncronization w/ audio. If the audio were on the timeline you could set sync params to stream, but if the audio is loaded programically forget it .. well until AS3 ..The following code throttles the player framerate to lock step the animation to the audio .. not perfect but the principal works ..
Let me first establish what I want to do:My user is able to record voicenotes on my website, add tags to said notes for indexing as well as a title. When the note is saved I save the path of the note along with the other info in my DB.Now, I have 2 choices to do the recording, both involve a .swf embedded in my site:
1) I could use Red5 server to stream the audio to my server and save the file and return the path to said file to my app to do the DB saving, seems rather complicated since I would have to convert the audio and move it to the appropriate folder that belongs to the user in a server side Red5 app, which I'm not very aware of how to build.
2) I could simply record the audio and grab its byte array, do a Base64 encoding on it and send it to PHP along with the rest of the data that is necessary (be it by a simple POST or an AJAX call), decode it on the server and make the file with the appropriate extension, audio conversion would also occur here using ffmpeg, this option seems simpler but I do not know how viable it is.
