unity videoplayer 的使用案例
Unity VideoPlayer 的使用案例1. 引言在现代的游戏开发中，视频播放已经成为游戏中不可或缺的一部分。
而 Unity 提供的 VideoPlayer 组件可以方便地实现视频播放功能。
在本文中，我们将探讨 Unity VideoPlayer 的使用案例，以便更好地理解如何在游戏中使用这一功能。
2. VideoPlayer 的基本介绍Unity 的 VideoPlayer 组件可以让我们在游戏中播放视频，支持多种视频格式，并且可以以纹理形式展示在游戏场景中。
这为游戏开发者提供了更多的可能性，可以在游戏中加入更多的剧情、故事情节或者广告内容。
3. 视频背景动画一种常见的使用案例是将视频作为游戏的背景动画。
通过VideoPlayer 组件，我们可以在游戏开始页面或者选关页面播放一个精美的视频，来吸引玩家的注意，为游戏增加更多的视觉效果。
4. 游戏剧情展示在游戏中加入视频可以更好地讲述游戏的剧情。
通过视频，我们可以展现更加丰富的故事情节，增加玩家的代入感和沉浸感。
在一些冒险类游戏或者解谜类游戏中，加入视频可以为游戏增加更多的趣味性。
5. 游戏广告内容在一些免费游戏中，开发者需要通过游戏中的广告来获得收益。
而VideoPlayer 组件可以很方便地实现在游戏中播放广告视频的功能。
通过精心设计的广告内容，可以为游戏增加更多的盈利机会。
6. 个人观点和理解对于我个人来说，我认为 Unity VideoPlayer 的使用案例是非常丰富多样的。
通过VideoPlayer，我们可以在游戏中呈现更多的内容形式，为游戏增加更多的亮点。
但在使用的过程中，我们也需要注意视频格式的兼容性、视频文件大小对游戏性能的影响等问题。
7. 总结与回顾通过本文的探讨，我们更深入地了解了 Unity VideoPlayer 的使用案例。
从背景动画到游戏剧情展示，再到游戏广告内容，VideoPlayer的应用范围非常广泛。
在游戏开发中，我们可以根据游戏的需求，灵活地运用 VideoPlayer 组件，为游戏增添更多的精彩内容。
VideoPlayer播放视频
VideoPlayer播放视频VideoPlayer的使用方法（Unity5.6以后才能使用）经测试之后，暂时仅支持的视频格式（格式工厂里面的）有avi，mp4，mov，wmv，webm （格式有问题，暂不支持音频，无声）。
使用步骤：(无需脚本即可播放)1.创建一个用于显示视频的“屏幕”，Hierarchy视图里面创建一个Plane，添加渲染纹理（在Assets里面创建，右键Create—>Render Texture,拖给Plane。
）2.Hierarchy视图里面右键Video—>VideoPlayer,在Video Player组件里面有个属性Source，有两个值VideoClip和URL，分别表示视频文件、视频文件路径。
直接拖进去。
完成复制。
同理选择URL（外部文件，本地和网络），把视频的路径赋值进去。
3.赋值完成后，播放会没有声音，需要添加一个Audio Source组件，拖到指定位置进行赋值。
4.以上即完成了视频播放的流程。
VideoPlayer可以使用一系列事件来监听播放的各个动作：errorReceived：错误监听到时被执行。
frameDropped：有丢帧发生时被执行。
frameReady：新的一帧准备好时被执行。
loopPointReached：播放结束或播放到循环的点时被执行。
prepareCompleted：视频准备完成时被执行。
seekCompleted：查询帧操作完成时被执行。
started：在Play方法调用之后立刻调用。
创建一个Plane，将Test挂上去。
即可播放代码控制：publicclass Test : MonoBehaviour {//public VideoClipvideoToPlay;private VideoPlayer videoPlayer;private VideoSource videoSource;private AudioSource audioSource;// Use this for initializationvoid Start(){Application.runInBackground = true;StartCoroutine(playVideo());}IEnumerator playVideo(){videoPlayer = gameObject.AddComponent();//用于播放音频audioSource = gameObject.AddComponent();videoPlayer.playOnAwake = false;audioSource.playOnAwake = false;//We want to play from video clip not from urlvideoPlayer.source = VideoSource.VideoClip;//将视频设置为播放，然后准备音频以防止缓冲// videoPlayer.clip = videoToPlay;videoPlayer.url = Application.dataPath + "/videos/2.mp4"; videoPlayer.source = VideoSource.Url;VideoClip clip = new VideoClip();//设置音频输出模式为AudioSourcevideoPlayer.audioOutputMode = VideoAudioOutputMode.AudioSource;//将视频中的音频分配给要播放的音频源videoPlayer.EnableAudioTrack(0, true);videoPlayer.SetTargetAudioSource(0, audioSource);videoPlayer.Prepare();while (!videoPlayer.isPrepared){Debug.Log("正在准备");yieldreturnnull;}Debug.Log("准备完成");videoPlayer.loopPointReached += EndReached;videoPlayer.Play();audioSource.Play();Debug.Log("播放中");while (videoPlayer.isPlaying){yieldreturnnull;}//会先打印End reached 再打印播放结束Debug.Log("播放结束");}void EndReached(VideoPlayer vPlayer) {Debug.Log("End reached!");}}。
vue-video-player的使用总结
vue-video-player的使⽤总结
由于公司的项⽬是⽹上教育的，像⽹易云课堂那种教育⽹站，因⽽会有很多课程需要在线观看的，所以视频插件是必不可少的。
由于我⽤vue开发项⽬，所以找视频插件也找和vue贴近的。
最后选择了vue-video-player。
这个视频插件还是挺好⽤的，好多事件都是可控的，挺⽅便的。
⾸先 npm install vue-video-player -S;
然后再main.js进⾏配置：
然后就可以在组件中使⽤了。
常⽤参数：
然后就可以按需使⽤⼀些事件，由于我们项⽬需要播放的时候进⾏视频埋点，还有暂停的时候需要统计⽤户的暂停时间，还有等视频播放完之后加个评分弹窗。
因⽽我使⽤了三个事件，播放事件，暂停事件，播放结束之后事件。
如何动态切换视频源呢？
就先写这些，后⾯想到关于该插件的其他信息再补充。

After that, 3Dmodels are rotated with the center lying on this point.4 FAQ and Inquiry4.1 F AQWhat size XVL file can be read?XVL files up to approximately 15MB in size can be opened and viewed on iPad 2. Actual performance may vary depending on the features of the model and the spec of devices. T ypically, 15MB XVL files can represent a CAD file of approximately 1GB or larger.I have XVL files copied or downloaded via iT unes and they are shown in the file list, but themessage ”iXVL Player cannot load an XVL which is not processed by iXVL Publisher.” appears to result in an error to open the files.iXVL Player can show only XVL files output by iXVL Publisher. XVL files output by XVL Converter or XVL S tudio can be shown on iXVL View.Although the XVL file was copied by iT unes, it is not displayed on the iXVL Player file list.Only XVL files with the extension .xv2 and .xv3 are supported by iXVL Player. xv2 and .xv3 is the extension used by P-XVL / V-XVL / U-XVL files. .xv0 files must be converted to .xv2 or .xv3 before viewing with iXVL Player.iXVL Player fails to open the file.This may occur when the XVL file is too large to process. If you encounter this, we recommend using XVL S tudio to create smaller files (e.g. sub-assemblies) from the larger file.Although I was able to open the file, not all of the data is displayed.This may occur in XVL files including a shape with an extremely large amount of display polygons.There is not solution at this time and we recommend using CAD system or XVL S tudio to divide the model into smaller segments.I restored iPad / iPhone from the backup file and the file name disappeared.When iPad / iPhone is restored from the backup file or the free storage space is running short, the XVL files with URLs downloaded from the Web site will disappear from the file list. This is the currentspecifications of iXVL Player. Please access to the Web site and download the files again.Is technical support available?T elephone support is not available for the free iXVL Player product.

flutter videoplayer实现原理
文章标题：深度剖析Flutter Videoplayer实现原理与应用一、引言在当今移动应用开发领域，视频播放已成为不可或缺的功能之一。
而在使用Flutter构建跨评台应用时，Videoplayer作为一个重要的组件，扮演着关键的角色。
本文将深入探讨Flutter Videoplayer的实现原理，并结合实际应用，从浅入深地解析其内部机制和功能。
二、Videoplayer基本概念在开始深入探讨Videoplayer的实现原理之前，让我们先了解一下Videoplayer的基本概念。
Videoplayer是Flutter中用于播放视频的插件，可以实现视频的播放、暂停、快进、倒退等功能。
在Flutter开发中，Videoplayer可以帮助我们快速高效地集成视频播放功能，提供良好的用户体验。
三、Videoplayer实现原理1. 插件封装在Flutter中，Videoplayer是通过Platform Channel封装的，通过与原生评台的交互实现视频播放功能。
在Android评台上，Videoplayer使用的是Android MediaPlayer或ExoPlayer来实现视频播放；而在iOS评台上，则是通过AVPlayer来实现。
Flutter的Platform Channel机制提供了良好的接口，使得Videoplayer能够与原生评台无缝对接，实现跨评台的视频播放功能。
2. 视频播放控制Videoplayer提供了丰富的API，用于控制视频的播放状态，包括播放、暂停、停止、快进、倒退等功能。
通过对视频的帧率、分辨率、码率等参数进行控制，Videoplayer能够实现流畅、稳定的视频播放效果。
3. 媒体资源加载在实际应用中，Videoplayer需要能够加载各种类型的媒体资源，包括本地文件、网络视频、直播流等。
Videoplayer通过与原生评台的交互，实现了多种媒体资源的加载方式，使得应用可以灵活地处理各种媒体资源的播放需求。
视频播放软件操作指南
视频播放软件操作指南第一章: 软件介绍视频播放软件是一种用于播放各种格式视频文件的工具。
它提供了方便的操作界面和丰富的功能，使用户能够享受高质量的视频娱乐体验。
例如，视频播放软件可以帮助用户管理视频文件、调整视频画面、添加字幕和音轨、创建播放列表等。
下面将详细介绍视频播放软件的基本操作指南。
第二章: 安装与卸载首先，用户需要下载并安装视频播放软件。
在官方网站或应用商店中，找到合适的版本，下载并双击安装程序。
根据提示进行安装，选择目标文件夹和其他相关选项，最后完成安装。
要卸载视频播放软件，可以在操作系统的控制面板或设置中找到已安装的程序列表。
选择视频播放软件，并选择卸载选项。
根据提示完成卸载过程。
第三章: 导入和管理视频文件当软件安装完成后，用户可以通过导入视频文件来开始使用它。
通常，在界面上会有一个“导入”或“添加文件”按钮，点击后会弹出文件浏览窗口。
用户可以浏览文件夹，选取所需的视频文件，然后点击“确定”按钮将其导入到软件中。
为了更好地管理视频文件，软件通常提供了一些实用的功能。
例如，用户可以创建文件夹来对视频文件进行分类，将相似的视频放在同一个文件夹下。
另外，软件还提供了搜索功能，可以根据视频文件的名称、格式、大小等属性进行搜索和筛选。
这样，用户就可以轻松找到所需的视频文件。
