html5-video

问题 I have an html page, and a link to the video in my code. Can I start buffering the video as soon as I've opened page, and show the 'play' button only when the video is completely buffered? Important, thet I should put this video dynamicly via innerHTML() when it's loaded.

The player, however, keeps repeating time 1-3 sec frame when repeat(5,7) is called. I know the issue is that video.currentTime >= 3 is true in

问题 I am streaming HTML 5 video with Express using fs.createReadStream(path).pipe(res); which eventually causes the error Error: EMFILE: too many open files if I refresh the page too many times (in the thousands). I assume I need to perform some kind of cleanup and close the file to prevent this but am unsure what needs to be done. I am creating a read stream every time the user seeks to a part of the video which the client has not loaded which makes this problem happen in a matter of minutes.
