ActionScript 3.0 :: NetStream.seek() Not Seeking To Start Of Video On Mobile
Nov 4, 2011
I have a "video on demand" video that I'd like to seek at any point of the video. It's playing on a Motorola Xoom tablet. I can seek to the beginning of the video when the playhead is near the beginning. However, if I the playhead is towards the end of the video and I attempt to seek to the beginning of the video, the video seeks many seconds after the start of the video. I thought this might be a buffering issue, so I set inBufferSeek to true, but I still have the same issue.

I am working on a Flash Video player and am implementing the ability to start a video at x time within the span of an FLV (served from FMS). I am able to start it x seconds into a stream without any issue using
netStream.play(source, startTime);
but as far as I can tell, it only supports seconds. I am looking to be able to give a start time (or even a seek time if that is supported) in milliseconds, or really anything more precise than whole seconds.
Anyone know of any way to achieve this even by monkey patching the fl classes?

I am working on an app that will take a snapshot of an rtmp stream of an archived video, save it to a file, and ExternalInterface the file name to the hosting page to javascript it up for display.
I actually have all pieces working great. The only time an error is thrown is when I pause the video, seek to somewhere, and then try to take a snapshot. Then there is a runtime error of:
SecurityError: Error #2123: Security sandbox violation: BitmapData.draw: mySwf.swf cannot access rtmp://myFlashServer/myApp. No policy files granted access.I've seen post after post of suggestions and have tried them, but without success.
I have the crossdomain.xml and my FlashMediaServer security setup fine (it is actually working, except for this one glitch). It just seems to be the pause-then-seek-then-BitMapData.draw() combination which is creating issues.
Another weird thing: after the error is thrown, if I resume the stream and take a snapshot, it works flawlessly again.

I have a simple flv player which connects to a CDN which can take header byte range requests if a user wants to skip through a flv without the need for the flv to be 100% loaded.I am using a third party http librabry to add the range header to the request.My code plays the flv but when I try to skip to 30 seconds into the video it just freezes. I beleive the cdn does return the file as i can trace through the bytes and the header has the content-range repsonse (below).[code]

When working with MOV files using the h.264 codec and AAC sound I am unable to get netStream.seek to work correctly. No matter what argument I pass to netStream.seek it will always seek to 0. I have this problem on both a legacy as2 and a newer as3 video player I have built. Regular flvs work perfectly on both players.

I have a series of movie clips (flv's). All are the same movie clip of a rotating object but it's different colour in each clip.When one clip is playing and I click to play another, I would like the clicked movie clip to start playing from the same position at which the previous clip was at. So if a clip had played for 3 seconds and I click a different clip, I would like it to seek and play from 3 seconds instead of 0.[code]Can anyone tell me how I would go about tracking the data of how many seconds of a clip has played?My guess is that it will either be metadata or NetStatusEvent related.

The problem is that I have an fla video player that uses the netstream class in order to pull a stream (mp4 h264), I've tried this with a few different mp4 files and they all behave the same..Basically, when I goto seek to a position, say 10 seconds into a 300 second mp4, the movie buffer goes blank and my readout of the current time I can see climbing from around 7 seconds and keeps going all the way to the end.. almost as if the seek command is trying to find a keyframe where it can resume from..I'm using http (not rtmp), and thus streaming directly from naive http.After awhile I decided to use the FLVPlayback component, set the source to the same, and it read in some initial metadata.. when I try the movie with the FLVPlayback component I can pause, seek resume to any position without problem, at first I was thinking the problem might have been http related but if the FLVPlayback component works then I'm a little stuck..Also note that I've checked the seekpoints of the movies and there are TONS of them, so the seek command should be able to find a nearby seekpoint to where I suggest.

It seems seek() on mp4 file seeks to the closest keyframe (seekpoint). Is it possible to seek to exact position in between of keyframes?

I'm trying to play an FLV using the Netstream class - standard stuff, really using nothing more complex than things you can find in the help files. I've created a control panel with a bar you can use to click and drag and scrub through the video.
Exporting to Flash Player 9, it's working fine and I can scrub through the video, but only while the FLV is still loading. As soon as it hits 100% the scrubbing (using Netstream.seek()) becomes incredibly unresponsive, almost to the point of crashing the player.
I've killed all ENTER_FRAMES, removed all unnecessary listeners and nullified everything I can think of but something massively resource-intensive seems to be kicking in as soon as the load finishes.
Has anyone ever seen this? I've never come across this and can't find anything similar across assorted forums.
Code below but I don't think the mouse-move drag actions are the problem! Fine in the Flash CS4 IDE, broken in the browser.
// Drag
private function dragVideo(e:MouseEvent):void {
// Match the x position of the dragger to the x position of the mouse
videoControls.progressBar.dragger.x = videoControls.progressBar.barInner.mouseX;

I am implementing a video player in Actionscript and I need to be able to define the starting play time for the videos. Netstream.seek(pos) works for flv files but fails for H.264 files (the player starts playing the video from the beginning). Anyone knows what might be the problem? (I am using Netstream for this instead of adding a parameter with the starting time when I call the Netstream.play method because I don't have Flash Media Server).

I am using OSMF v1.0 along with FMS 3.5.3 and flash player 10.1. Whenever i do a seek, lets say to a time 't'. Netstream.time gives me an incorrect result which is more than 1.5*t (varies). So if i seek to 100, i get netstream.time as approx. 160. I also noticed, 'NetStream.info.VideoBufferLength' goes very high (from around 3-4 to 50-60) just before the Netstream.time parameter gets updated and drops backs after update.

I try to start a FLV (created with soundbooth cs5) at a certain point of time using ns.play('video', 33000) or even just ns.seek(33000);
The FLV is about 9 hours long.
How do I make this work ? And why is it not working?

At the moment i am using vlc to transcode my video realtime and display the output through Flowplayer.The problem is that I am struggling to seek using flowplayer my time gets out of sync between the stream and flowplayer and there are a few other issues.Are there any streaming servers that allow for real time transcoding and allow for a flash player to seek.

Normally we use NetStream.Seek method but it will make the seek after the buffer area crossed the seek time length.(HTTP). Can we seek the video that is beyond the buffered area like youtube in red5. Will it start the buffer from the seek point.

Here's what's going on: I have an F4V file loaded into a SWF. There are no real playback controls -- nor do I want any. I've created a "skip" button that's supposed to a) pause (or seek to 0) the video, then remove the video from the stage. It seems I can either pause the video OR seek to zero, but not both.Here's what I've tried:
Code:
function seekTo (num:Number):void
{

I made an interface that laods a FLV video (as far as I know this is progressive download as I'm not using any Flash Media server or whatever).The point is that I added a Button on the stage with the following code:
on (release) { _root.stream_ns.seek(15); }
I also have a event catcher like this in the main timeline:
stream_ns.onStatus = function(infoObject:Object) { if (infoObject["code"] == "NetStream.Seek.InvalidTime") { _root.text_display = "Not loaded yet"; }}

I was told there is a server technology that allows user to seek to a part of video that has not been loaded yet even if I am using progressive download, not true streaming.

I am working on a system that requires me to be able to load large video files using Flash. However, the problem I am running into is that users need to be able to seek to a random point in the file that may or may not be downloaded yet and have it instantly start playing (think Youtube). The video files can be hosted anywhere, and thus I do not have the ability to install policy files or anything of the like.
I have looked into this, and cannot find any answers. Does anyone know of a way to enable this random seeking in Flash files without policy requests or an RTMP server installed at the destination?

I have an Embedded (synchronized with timeline) clip in a flash movie.I am controlling the currentFrame of the clip by dragging a slider left to right (to simulate rotating an object).The problem is when I go forwards, motion is smooth, but if I drag to the left Flash cannot seem to efficiently play back in reverse and the motion is extremely jerky.Obviously I'm skipping frames depending upon the position of the mouse, but there is a very noticable lag when currentFrame is decreased vs. increased. Is there a way to optimize an embedded timeline clip for reverse random seeking like this?Possible solutions (untested) :Use video instead of embedded - I would expect this to make the situation worse though!Create a second reversed video for when scrolling to the left. This would probably double the file size.

I have made a video player based on the code from Lee's tutorial and I have modified it with help from code found in this forum. The video is paused from start and thats fine, but the bufferClip shows all the time (like forever) until i press the play button, I just want the bufferClip to be visible for as long the video is buffering.
Code: Select allns.setBufferTime(4);
var firstPlay:Boolean = true;
ns.onStatus = function(info){

I have two FLV files playing on the stage. The main FLV is instance is: MyVideothe 2nd is MyVideo2I have imported the videos using the wizard. The 2nd video is just a movie I created in Affter Effects that says...loading please wait....this is a really nice video and I don't want it to just use a standard preloader. Anyway, the goal is when the playback for "MyVideo" begins I would like "Myvideo2" to = visible = false;I have tried this many different ways and have been unsuccessful. I am obviously a newb at this. Also, does anyone know where I can get a list of all available eventListener actions...etc?
//var nc:NetConnection = new NetConnection();
//connection_nc.connect();
//var stream_ns:NetStream = new NetStream(connection_nc);

Does anyone know of any tutorials that explain how to make a seek bar with a handle that will be linked to the main timeline, so that when you move the handle the animation will move too, e.g. if you drag the handle to the centre of the bar then it will skip to the middle of the animation?
I currently have a handle that move on the x axis with in a set boundary, but not sure how to link it to the main timeline.
