设置 Apple TV 视频 JavaScript [英] Setting up Apple TV video JavaScript
问题描述
我有一个简单的函数可以启动处理 Apple TV 视频播放的 player
I have a simple function that will launch the player
that handles video playback for the Apple TV
function launchPlayer() {
var player = new Player();
var playlist = new Playlist();
var mediaItem = new MediaItem("video", "http://localhost:9001/videos/nsoperations.mp4");
player.playlist = playlist;
player.playlist.push(mediaItem);
player.present();
}
根据 播放器文档,播放视频所需的只是播放器、播放列表(docs),以及一个媒体项目(文档).我已经掌握了所有这些,但是在运行我的代码时,出现错误:无法同时满足约束.
据我所知,我们不处理这些内置播放器的自动布局.我用错了播放器吗?
According to the Player Documentation, all I needed to play a video back is a player, a playlist(docs), and a media item(docs). I've got all those, but when running my code, I get an error:
Unable to simultaneously satisfy constraints.
To my understanding, we don't deal with auto-layout for these built in players. Did I use the player wrong?
错误的完整细节如下:

Probably at least one of the constraints in the following list is one you don't want.
Try this:
(1) look at each constraint and try to figure out which you don't expect;
(2) find the code that added the unwanted constraint or constraints and fix it.

Will attempt to recover by breaking constraint
<NSLayoutConstraint:0x7f8162c86800 UIImageView:0x7f8162e22190.bottom <= _UIAlertControllerActionView:0x7f8162ec3a30.bottom - 6>
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

推荐答案

Your sample is ok and do work. Even with the constraint errors, but player is not very forgiving.
我认为您正在使用 Python SimpleHTTPServer 进行测试,它不适用于视频流,但是如果您使用 Apache 或例如直接来自苹果的此文件http://trailers.apple.com/movies/focus_features/9/9-clip_480p.mov" 它将起作用.
I think you're using the Python SimpleHTTPServer for your test, it did not worked for video streaming, but if you use Apache or for example this file directly from apple "http://trailers.apple.com/movies/focus_features/9/9-clip_480p.mov" it will work.
