flv播放器控制时间
我正在使用 Flex flv 播放器组件，我希望能够向前和向后跳过 5 秒，目前从我从文档中了解到的情况来看，这是不准确的，因为电影只能跳到关键帧，有时会跳过 6 或7秒。这同样适用于提示点，如果那里没有关键帧，flv 可能会错过实际点/ 我的问题是还有其他方法可以更准确地使用播放器吗？因为我在网络上看到可以执行这些跳过的播放器
谢谢
I am using the flex flv player component and i want to be able to skip 5 seconds forward and backwards , at the moment from what i understand from the documents it is not acurate because the movie can only skip to keyframes sometimes making the skip 6 or 7 seconds. the same goes to cue points which the flv might miss the actual point if there is no keyframe there/
my question is there any other way to use the player in a more accurate manner ? since i see on the web players that can do these skipps
Thanks

查找 FLV 文件的能力完全取决于关键帧间距。这是因为关键帧本身就可以创建整个视频图像。 （与帧内帧相反，帧内帧依赖于a）前一个关键帧，以及b）它和之间的所有帧间帧前一个关键帧。）这就是他们的工作方式。
但也许您对视频的编码方式有一些影响？您能指定最小关键帧间距吗？例如：25fps 视频的关键帧间隔为 50，即每 2 秒一次。或者更小？
No
The ability to seek into an FLV file is entirely dependent upon the key frame spacing. That is because a key frame can create an entire video image all by itself. (As opposed to intra-frames, which are dependent upon a) the previous key frame, and b) all inter-frames between it and the previous key frame.) That's just they way it works.
But maybe you have some influence over how the videos are encoded? Could you specify a minimum key frame spacing? E.g.: A key frame spacing of 50 for a 25fps video would be every 2s. Or even smaller?
我开发了这样一个播放器，你可以使用flv-player.net，也可以复制js播放器。没有控制栏，因此您可以通过 javascript 控制所有功能，
下载 flv-player.js.swf 以及演示代码，编写您自己的控制栏，即播放、搜索、暂停、音量和全屏。
因此，您将需要额外的努力来编写这些功能，因为我提到的播放器没有任何控制栏。
I have developed such a player, you can use flv-player.net, and copy js player. there is no control bar, so you can then control all the feature from javascript,
download flv-player.js.swf along with demo code, write your own control bar, mean play , seek , pause , volume , and fullscreen.
So you will need extra effort to write these feature becuase the player that i mention have not any control bar.
