寻求在 flex 4.5 netStream byteArray 中不起作用 [英] seeking not working in flex 4.5 netStream byteArray

问题描述

我正在尝试使用 netStream byteArray 在 flex 4.5 中播放 flv 视频文件.我正在做的事情如下:

I am trying to play a flv video file in flex 4.5 with netStream byteArray. What I am doing is below:

1. 创建 netStream 和视频对象
2. 附加带有视频的 netStream
3. 在 byteArray 中读取 flv 文件
4. 使用appendBytes"方法在 netStream 中附加 byteArray
5. 播放视频

在这种情况下，播放、暂停、停止功能可以很好地处理视频.

In this scenario Play, Pause, Stop functionalities are working fine with video.

但是当我尝试在视频中寻找时，它不起作用.

But when I am trying to seeking in video then it is not working.

谁能告诉我，我在实现搜索时哪里出错了.

Can anybody tell me, where am I am going wrong to implement seeking.

任何代码示例或任何类型的帮助将不胜感激.

Any code sample or any kind of help would be appreciated.

推荐答案

我明白了，下面的代码适用于我的情况

I got, the code below worked in my case

// onmetadata function get all timestamp and corresponding fileposition..
function onMetaData(informationObject:Object):void 
{
    for (var propertyName:String in informationObject) 
    {
        if (propertyName == "keyframes")
        {
            var kfObject:Object = informationObject[propertyName];
            var timeArray:Array = kfObject["times"];
            var filePositionArray:Array = kfObject["filepositions"];

            for(var i:int=0;i<timeArray.length;i++)
            {
                var tagPosition:int = filePositionArray[i];//Read the tag size;
                var timestamp:Number = timeArray[i];//read the timestamp;
                tags.push({timestamp:timestamp,tagPosition:tagPosition});
            }
        }
    }
}

// onseek click get approximate timestamp and its fileposition
protected function seek_click(seektime:Number):void
{
    var currentTime:Number = 0;
    var previousTime:Number = 0;

    for (var i:int=1; i<tags.length; i++)
    {
        currentTime = tags[i].timestamp;
        previousTime = tags[i-1].timestamp;

        if(previousTime < seektime)
        {
            if(seektime < currentTime)
            {
                seekPos = tags[i-1].tagPosition;
                stream.seek(previousTime);
                break;
            }
        }
    }
}


// append bytes on seekposition
private function netStatusHandler(event:NetStatusEvent):void 
{
    switch (event.info.code) 
    {
        case "NetStream.Seek.Notify" :

        stream.appendBytesAction(NetStreamAppendBytesAction.RESET_SEEK);
        totalfilePositionArray.position = seekPos;

        var bytes:filePositionArray = new filePositionArray();

        totalfilePositionArray.readBytes(bytes);
        stream.appendBytes(bytes);

        stream.resume();

        break;
    }
}

为了将元数据关键帧注入到 flv 文件中.使用一些注入器工具，fe.FLV 元数据注入器

For inject MetaData keyframes into flv file.Use some injector tool, fe. FLV MetaData Injector
