Actionscript 3 :: Video Buffering Impact To Video Over A Slow Connection?
Apr 12, 2012
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.
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 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'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:
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.
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.
I'm trying to implement a simple NetStream video player with Progressive Video, but for some reason the video is taking about 12-13 seconds to begin buffering...I don't get it. If you check this link, you can see the buffer progress, you can see that it sits at 0 for >10s, until finally starting to buffer, at which point it finishes very quickly. [URL] It's a hard one to search for as any query using connection or slow obviously returns a bunch of crap that I don't need...
i have an embedded video in my .fla. It's like the "background" of the scene. I need to slow down this video in a specific keyframe, and then return to the normal speed.
I managed to make a controller that can play embedded-video-SWF's in "slow-motion" (1/2 speed, 1/4 speed) and in reverse at different speeds. What I'd actually like to do, is something similar, but then with FLV's. I am trying to use the NetStream.pause() as a toggle onEnterFrame, but that doesnt work. Using seek doesn't seem to work either, because it kind of doesn't like non-integers and also for an unknown reason keeps sending the playhead to 4 seconds. if it should be possible to play an FLV at a different speed/reversed, how to do this, and if this should cause performance issues. (Reverse-playing an SWF is much slower for example)
I have an instance of the flvPlayBack component on my stage called myVideo a list of links down the lhs is used to pop in the required video.If a user gets say 1/3 of the way into a video and the presses a different link for a different video then: the new video pops up but the seek bar is still some way into the new video there is a pause of around 1 sec the seek bar goes back to the start.I want to speed up the return of the seek bar to the start of the new video.
Here's some code:
Code:
function clickHandler(event:MouseEvent):void { this.myVideo.alpha=1; if (linkType !="http"){
[code]....
This might be wrong but do I need to somehow remove the reference to the "old" video before I set the source to the new one?If that's junk - and it probably is ...How can I speed the return of the seek bar to the start of the new video?
I have a Flash video playing as part of a jQuery slideshow. But it seems not to be autoplaying successfully, and is loading very slowly. It usually loads on refresh, but not when someone first hits the page.The video is at link removed as it will be outdated shortly - we're moving to production; besides, the problem is solved.
It is not a daylight discussion, but It is not the first time I got myself researching about that with no success at all. After all, what could be done when Full Screen Flash Video consumes up all the computer resources?
1) Is it a hardware/driver issue? 2) Is it about developing best-practices? 3) Is it some especific configuration on FLV exporters? 4) Is it a Flash Player limitation?
I have noticed some sites provide a really smooth full-screen video experience, but some others shows themselves up with a hell of video performance. My inclination, in a first approach, is towards thread 2. I have done some tests and all of them ended up in a clunky horrible show-time.
I'm working with flowplayer and accordingly ActionScript. This project has slowmotion plugin, but there are two imperfections: it uses the special stream server and no sound in slow motion. Is there possibility to play flash video and audio in slow motion by just add something in ActionScript?
Flash cS 5.5 / Win 7. Inserting video into movieclip both with 'import video' wizard and via component. FLV that plays fine on a number of different servers. On opening (after gathering metadata) the message 'The video player is in the connection error state. It enters this state when a video stream attempted to load but was unsuccessful. There are two possible reasons for the error: no connection to the server or the stream was not found.' Firstly I am treating this as a progressive download, not streaming. Second this plays fine locally, it's only when I upload to a server it fails.
The FLV is in a folder directly below the SWF. Result is same with FLV in same location as SWF. MIME type set to vide/x-flv although I've also set it to application/octet-stream. This is a very basic requirement to call the video directly from Flash, the default parameters of the component are adequate and work locally. However the video does not play. Is it fair to assume this functionality simply does not work correctly within Flash CS5.5? I'm unclear as to what >less< I could be doing with this file.
I'm building a video player, and I'd like the play to show a "Loading, please wait"-type animation whenever the video is buffering and not playing. (This is either when the user enters the page and the video has to buffer a bit before it can start playing, or when the video suddenly stops midway because the internet connection can't load video fast enough.) Is there a way to detect when this happens and show the animation accordingly?

I have a web site that displays a column of flash videos. The page is w3c-valid. The problem is that the page loads very slowly and sometimes crashes my web browser. Until the page is fully loaded, the videos are slow to respond and play. Is there a way to make these videos load their preview images only? What should I do to speed the page up? The videos are 360x264.
