I have a small app using Vue.Js (with webpack). I have a transition section. When the user clicks to a button the content going to change. It's a simple DIV element with an IMG child element.

iOS: AVPlayer video preloading

拜拜、爱过 提交于 2019-12-03 12:46:04
I am using AVPlayer to play videos. The lenght of them is short, 2-5 second. They are played in a random order. The problem is, when changing video, and a new video starts to play, the device lags for a very short time, but i wan't the change to be fluid. Is there a way to preload videos with AVPlayer? Till Try using AVQueuePlayer . I am assuming that what you described as a lag, in fact is the pre buffering delay. This should be minimized or actually entirely be gotten rid of when using AVQueuePlayer as that baby will buffer the next AVPlayerItem while playing the current one. From the

Wait for images to load and then execute all other code

↘锁芯ラ 提交于 2019-12-03 12:34:38
OK, I'm losing my mind over this. I did read here at SO and google about it, I even have the preloader set (found here on SO), but none of the plugins/code I found helped me. What I want to do is: wait until all images are preloaded and only then execute all other javascript code. As far as I'm concerned it can (but not a must) have a "loading..." message. The fact is that I have a pretty big image in the body background and 2 other images which are also bigger, and so I would like to preload them so that then they would show instantly and would not have that ugly "loading" image effect. This

自古美人都是妖i 提交于 2019-12-03 11:47:22
问题 I have a lenghty ASP.NET page load process. Is there a way to display a loading gif while the ASP.NET page loads?

html5 video preload

a 夏天 提交于 2019-12-03 02:00:33
Is it possible to preload an html video? Note: the tag is created dynamicly later. Currently I can do this with images by creating a hidden div and putting all the images in there. Then when I create the need later the image does not need to be reloaded. When this is done with a video tag, the browser still loads the video from the beginning when the element is created. I saw this: https://github.com/jussi-kalliokoski/html5Preloader.js , but it does not seem to work with videos. Any ideas would be appreciated! Try this out: <!DOCTYPE html> <html> <body> <video width="320" height="240" controls
