我正在为我的网站上的视频开发自定义分析解决方案...这些功能映射到 Flash 播放器和 HTML5
一般设计建议将不胜感激，但我特别好奇我应该多久更新一次观看值百分比...我想我应该设置一定的百分比阈值而不是根据时间（例如，每 5 或 10个百分点）。
然后，就将数据发送回服务器而言，我想我只需使用常规的 Ajax POST 请求，这将更新 MySQL 数据库。
问题是，当我研究 Vimeo 和 YouTube HTML5 播放器时，我无法检测到他们如何处理分析 - 所以我想知道他们是否有更好的实现（？），因为我无法想象他们没有有任何分析。
为每个视频播放发送 20 或 10 个 Ajax 请求似乎有些低效（这也需要相当多的 MySQL 更新）——而且保真度甚至没有那么高。
（抱歉，这个问题有点漫无目的——我找不到关于这个主题的太多信息。）

如何Wistia 吹嘘他们跟踪“个人观看次数的逐秒观看统计数据”？ （也就是说，无需发送大量请求。）
I'm developing a custom analytics solution for videos on my site... the functions are mapped to both a Flash player and a HTML5 <video> player.
General design advice would be greatly appreciated, but I'm specifically curious how often I should update the percent watched value... I was thinking I'd set a certain percentage threshold rather than according to a time (say, every 5 or 10 percentage points).
Then, as far as sending the data back to the server, I was thinking I'd just use regular Ajax POST requests, which would update a MySQL database.
Thing is, when I researched the Vimeo and YouTube HTML5 players, I couldn't detect how they were handling analytics — so I'm wondering if they have a better implementation (?), as I can't imagine that they don't have any analytics.
Sending 20 or 10 Ajax requests for each video play seems somewhat inefficient (and that's quite a few MySQL UPDATEs, too) — and the fidelity isn't that high even.
(Sorry for the somewhat scattershot question — I can't find much info on the subject.)
POST-ANSWER EDIT
How can Wistia boast they they track "second-by-second viewing statistics for individual views"? (That is, without sending a huge number of requests.)

我会有时发送更新 50% 25% 12.5% 6.125% ...等等（以相反的顺序），直到时间分辨率变得太高（从几秒到一分钟也许......你的选择）。
这样您就可以知道哪些视频被完全/大部分观看，哪些视频被快速忽略。
当然，可能有很多变化，但关键思想是在一开始就拥有最佳分辨率。
I would send update at times 50% 25% 12.5% 6.125% ... and so on (in reverse order) until time resolution gets too high (from a few seconds up to minute maybe.. your choice).
That way you'll know which videos are watched fully/largely, and which ones are quickly dismissed.
There are of course many variations possible, but the key idea is to have best resolution in the beginning.
跟踪对您的报告需求有用的百分比。对于需要了解视频总体“健康状况”的客户来说，跟踪 50% 和 100% 的完成率对于大多数人来说就足够了。除此之外，跟踪 25%、50%、75% 和 100% 可以提供大量信息。
想想为什么您需要知道某人观看了视频的 5% 与视频的 10%。如果你能想出某种方法来在该级别上进行改进，那么无论如何，都要跟踪该级别。否则，请采取能够以最小的负载影响获得最佳报告效果的方法。
Track at percentages that will be useful for your reporting needs. For clients that need to know the general "health" of their videos, tracking at 50% and 100% completion rates is enough for most. Beyond that, tracking at 25%, 50%, 75% and 100% gives a really good amount of information.
Think about why you'd need to know that somebody saw 5% of a video vs 10% of a video. If you can think of some way to make improvements at that level, then by all means, track to that level. Otherwise, do what will get you the best reporting impact with the least load impact.
