ActionScript 3.0 :: Netstream AppendBytes And Seeking
Sep 13, 2011
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]

I am using NetStream.appendBytes() to play a local video (no server involved) in Adobe AIR. I would like to use BitmapData.draw() to take a picture of the video output, but I am getting this error:
Error #2123: Security sandbox violation: BitmapData.draw: cannot access null. No policy files granted access.
Here is some sample code:
package
{
import flash.display.Sprite;
import flash.filesystem.File;
[Code].....
This is only sample code use for an explanation. The error would happen when calling the getImage method while the video is playing. The error mentions a policy file not found. Since the file is loaded locally there isn't really a place to put a policy file. Is there a policy setting somewhere that needs to be set or is the BitmapData.draw feature just not available when using appendBytes?

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 have a problem with my video player, I'm doing the video display through a seekbar appendBytes and I have but I can not make the video go to a certain point of view when I click on seekbar. I found that the problem is in how I view the video, which is the appendBytes.

I'm making a small video players in AS3, and I've found that after calling NetStream.pause() or NetStream.togglePause(), no status messages are being fired any more.If I click the "pause" button while the video is buffering, I never get the Buffer.Full message.Here is some code:
_connection = new NetConnection();
_connection.addEventListener(NetStatusEvent.NET_STATUS, netStatusHandler);
_connection.connect(null);[code].....

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 HTTP video player built using Adobe's OSMF and I am experiencing a strange behavior when trying to seek within a subclip.The player requests data from the server using URL like "http:[url]...." to get the full video, and appends "?begin=123456" to request a subclip starting at 123456 bytes offset.Whenever I try to seek within a loaded subclip, the playhead just drops to the start of the subclip and the video plays from there. Although both mediaPlayer.canSeek() and mediaPlayer.canSeekTo(newtime) return true.

I'm looking for a way to add seeking capability to audio playback. I can do it pretty easily for video, but I'm currently using a sound object which has no seek capabilities whatsoever.
Is there a different object or method I can use to direct audio playback to a particular point in the audio duration?[code]...

I used a template from adobe and modified it to fit my needs. Instead of one long video with cuepoints, I have several videos that I want to switch when the buttons are clicked.verything works great except when the user seeks beyond the buffer (progressive download).hen this happens, everything breaks. All of the buttons, playback, play/pause... everything. You have to refresh the page and start over.My quesiton is, does the seekBar need a custom eventHandler? Shouldn't it work on it's own? Here is my code:
import flash.events.*;import fl.video.*;
//-----------------// Video control assignment//-----------------
display.playPauseButton = play_btn;display.stopButton = stop_btn;display.seekBar =

I have an flv with some navigation cue points embedded in it. The video is pretty long. When I upload it to my site, I cannot access cue points in unbuffered parts of the video. What do I need to do so I can jump to unbuffered parts of my video?

I'm making DVR application and I'd like to use h-264 codec, but got following problem. While f4v file is recording, client application (for example Adobe DVR Sample Application player) cannot seek inside the video. It starts playing sought part of the video and stops in few seconds. When recording process finishes the seek works correctly in the recorded file. The process described above works fine when I use vp6 codec. I am using FMLE 3.1 and FMIS 3.5.3

So I run into this issue that Enhanced Seeking is enabled by default. And I would really like to disable it (long story here). But it seems you can only disable it on the FMS, by adding this setting to the application.xml. But the thing is we are not sure if we will end up using an FMS or not. So, can I disable Enhanced Seeking without using FMS?

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.

I am trying to achive is the "SEEK" effect that you find on YouTube. Like suppose the Video is 20 Minutes long and only 5 minutes are loaded and if you click on the 15th minute, the video will start playing from that point.I saw a PHP script some time back which would return the "FLV" which starts from the point which is requested to the PHP Script. I didn't bookmark that I don't know why and it was really long time back.

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

The problem is the sound doesn't play in this way. What should i do ?

I need to get H.264 videos streaming. I've gotten the mp4 file playing and buffering, which is great, but when I try to seek ahead to a part that isnt buffered, the video stops, goes to the start of the video, and will no longer play. FLV files behave exactly as I would like them to, meaning they go to selection position and start buffering and playing from there. Here is my progressiveSeek function:[code]keyFramesSeconds and keyFrames Bytes are just arrays that hold the metadata for the seekpoints. This function, when called on the H264, goes to the beginning and stops the video, but when called on the FLV, does what I want. How can I do progressive seek for an H264?

I have a VideoDisplay instance playing some video. When I click on the video slider (also my component) the property videoDisplay.playheadTime is set and the videoDisplay.state goes from 'playing' into a 'seeking' state for a brief moment (the videoDisplay seeks for a new position and then plays the video again). Intended bevaiour. But if I'm (or any random user) fast enough, I can set the playheadTime again while the player is still in 'seeking' state. When repeated several times every click is enqueued and the videoDisplay jump on every place of the video I have clicked(this is happening in an interval about 10-15 second after my last click). When I use live dragging the videoDisplay, overwhelmed by seekings, goes into 'error' state.My question is - is there any way to cancel seeking state of the VideoDisplay class? For example player is in 'seeking' state, I set playheadTime, and the player forgets about last seeking and try to find the new place of the video.
