您是否遇到无法在 iPhone 或 iPad 上播放的视频的问题？您用来播放视频的应用程序可能什么也不做或显示空白屏幕。或者它最终会冻结或崩溃。了解如何解决这个问题。
由于多种原因，视频(Videos)无法在您的 iPhone 上播放。损坏(Corrupt)的视频下载、不兼容的文件格式和其他问题可能是一个因素。值得庆幸的是，您只需进行一些故障排除即可修复 iPhone 上的视频播放问题。
1.强制退出并重新启动应用程序
最好先强制退出并重新启动无法在 iPhone 上播放视频的应用程序。这可以清除损坏或错误的应用程序状态，并且是大多数意外问题的快速修复。
例如，如果Apple TV 应用程序出现问题，请从屏幕底部向上滑动（或双击主(Home)屏幕按钮）以打开应用程序切换器(App Switcher)，然后将电视卡滑开。接下来，通过主屏幕(Home Screen)或App Library重新启动(App Library)Apple TV 。
2. 检查您的互联网连接
(Poor)在YouTube(YouTube)和Netflix等应用程序上流式传输内容时，网络连接(Netflix)不佳可能会导致视频播放卡住或不稳定。如果它必须从 iCloud 获取你的 iPhone 相机胶卷视频，
这甚至会影响照片应用程序。(Photos)
要确认，请使用Fast.com(Fast.com)等在线工具运行互联网速度测试。如果结果看起来不太好，请尝试以下快速修复：
- 打开飞行模式(Airplane Mode)，然后关闭。
- 前往Settings > Wi-Fi ”，然后忘记并重新加入您当前的 Wi-Fi 网络。
- 重新启动 Wi-Fi 路由器（如果可能）或切换到其他无线网络。
- 切换到蜂窝(Cellular)网络并配置应用程序的首选项以允许通过移动数据进行流式传输或下载。
- 重置手机的网络设置（更多内容见下文）。
3.检查服务器状态
服务器端问题是视频无法在 iPhone 上流式传输或下载的另一个原因。大多数流媒体服务经常在其网站上广播服务器状态，您可以检查以确认。或者，您可以使用DownDetector(DownDetector)等第三方在线状态监控工具。如果出现服务器中断，您除了等待之外别无他法。
4. 重启你的 iPhone
重新启动 iPhone 是解决系统软件及其上运行的应用程序意外问题的另一种快速方法。
要重新启动任何 iPhone 型号，请打开设置(Settings)并点击General > Shut Down。然后，关闭设备并按住电源(Power)按钮将其重新打开。如果视频显示冻结且屏幕无响应，请改为强制重启您的 iPhone(force-restart your iPhone instead)。
5. 更新应用
虽然不能保证，但安装应用程序的最新更新可以在解决导致 iPhone 上视频播放问题的已知错误方面发挥重要作用。打开App Store，搜索有问题的应用程序（例如，YouTube ），如果选项可用
，点击更新。(Update)
注意：要更新照片和电视等原生(Photos)Apple应用程序，您必须更新 iOS。稍后再谈。
6.卸载应用程序并重试
接下来，考虑删除并重新安装有问题的应用程序。为此，请打开“设置”(Settings)应用并点击“General > “ iPhone 存储”以显示 iPhone 应用列表。然后，点击删除应用程序(Delete App)（如果您不想丢失大量下载的视频文件，则点击卸载应用程序）。(Offload App)然后通过App Store搜索并重新安装该应用程序。
注意：iOS 限制您删除照片(Photos)应用程序。作为一种解决方法，请转到Settings > Photos并关闭 iCloud照片(Photos)，然后再打开。此外，如果您的 iPhone 存储有足够的可用空间，请选择“下载(Download)并保留原件”(Keep Originals)选项以在本地缓存您的照片库。
7.下载兼容的应用程序
假设(Suppose)您在其他网络浏览器上播放使用Safari下载的视频剪辑时遇到问题。在这种情况下，它可能是您的 iPhone 本身不支持的视频格式，例如MKV或AVI。像VLC Player这样的专用媒体播放器将允许您开始播放它。
要在其他应用上打开不兼容的视频文件格式，请尝试在“文件”(Files)应用中打开该文件。然后，点击共享(Share)图标并选择共享表(Share Sheet)上的应用程序。
或者，PC 或 Mac 上的视频转换器(video converter on a PC or Mac)可以将视频重新编码为与 iPhone 兼容的格式(re-encode videos in an iPhone-compatible format)，如 HEVC、MOV 或 MPEG。
8.删除损坏的下载(Delete Corrupt Downloads)并重试(Retry)
下载的视频有时会损坏并拒绝播放。在这种情况下，唯一的解决方法是删除并重新下载它们。
例如，切换到Netflix上的“(Netflix)下载(Downloads)”选项卡，点击“编辑(Edit)”图标，然后点击要删除的电影或剧集旁边的“删除”图标。(Delete)然后，再次下载视频或流式传输。
9.清除浏览器cookies和缓存
如果在线视频在Safari中加载或播放时出现问题，则损坏的浏览器缓存可能是问题的根源。清除 cookie 和缓存可能会有所帮助，因此请转到Settings > Safari，然后点击清除历史记录(History)和网站数据(Website Data)。
您使用不同的网络浏览器吗？了解(Learn)如何在 iPhone 上的任何浏览器中清除缓存(clear the cache in any browser on iPhone)。
10. 安装系统软件(System Software)更新
过时的 iOS 版本也可能导致 iPhone 上的视频播放和其他问题。要将 iOS 更新到其最新版本，请打开“设置”(Settings)应用并点击“General > Software Update > Download并安装(Install)” 。
另一方面，iOS 的 Beta 版本经常受到严重错误和其他问题的困扰。如果您注册了Apple Beta 软件计划(Apple Beta Software Program)，我们建议您将 iPhone 降级到稳定(downgrade your iPhone to the stable channel)版。
11. 重置你的 iPhone 设置
如果 iPhone 上的视频播放问题仍然存在，那么是时候将 iPhone 上的网络设置恢复出厂设置了。通常，这会修复阻止视频播放的不正确网络设置。
为此，请打开“设置”(Settings)应用并点击“General > Transfer或重置(Reset)iPhone > Reset > Reset Network Settings。然后，输入您的设备密码并再次点击重置网络设置(Reset Network Settings)进行确认。设置重置后，手动加入 Wi-Fi 网络并尝试再次播放视频。
如果重置网络设置没有影响，请重新访问上面的同一屏幕，但选择重置所有设置(Reset All Settings)选项。这会将所有 iPhone 设置恢复为默认设置，并有助于解决可能阻止您的 iPhone 播放视频的更深层次的潜在冲突。

Videos Won’t Play On Your iPhone? Try These 11 Fixes
Do you have trouble with vidеоs not playing on your iPhonе or iРad? Perhaps the app you’re using to play thе vidеo does nothing or shows a blank screen. Or mаybe it ends up freezing or crashіng. Learn how to fix that.
Videos won’t play on your iPhone for several reasons. Corrupt video downloads, incompatible file formats, and other issues can play a factor. Thankfully, a little troubleshooting is all you need to fix video playback issues on your iPhone.
1. Force-Quit and Relaunch App
It’s a good idea to begin by force-quitting and relaunching the app that fails to play videos on your iPhone. That clears a corrupt or buggy application state and is a quick fix for most unexpected issues.
For example, if the Apple TV app is causing problems, swipe up from the bottom of the screen (or double-click the Home button) to open the App Switcher, then swipe away the TV card. Next, relaunch Apple TV via the Home Screen or App Library.
2. Check Your Internet Connection
Poor network connectivity can result in stuck or erratic video playback while streaming content on apps like YouTube and Netflix. That even affects the Photos app if it has to fetch your iPhone camera roll videos from iCloud.
To confirm, run an internet speed test using an online tool like Fast.com. If the results don’t look good, try the quick fixes below:
- Toggle Airplane Mode on, then off.
- Go to Settings > Wi-Fi, and then forget and rejoin your current Wi-Fi network.
- Restart the Wi-Fi router (if possible) or switch to a different wireless network.
- Switch to Cellular and configure the app’s preferences to allow streaming or downloading over mobile data.
- Reset your phone’s network settings (more on that further below).
3. Check the Server Status
Server-side issues are another reason videos won’t stream or download on your iPhone. Most streaming services frequently broadcast the server status on their website, which you can check for confirmation. Or, you can use a third-party online status monitoring tool like DownDetector. If there appears to be a server outage, you’ve got nothing to do except waiting.
4. Restart Your iPhone
Restarting your iPhone is another speedy method to fix unexpected problems with the system software and the apps that run on it.
To reboot any iPhone model, open Settings and tap General > Shut Down. Then, power down the device and hold the Power button to turn it back on. If the video appears frozen and the screen is unresponsive, force-restart your iPhone instead.
5. Update the App
Although there’s no guarantee, installing the latest updates for an app can play a significant role in resolving known bugs that cause video playback issues on iPhone. Open the App Store, search for the app in question (e.g., YouTube), and tap Update if the option is available.
Note: To update native Apple apps like Photos and TV, you must update iOS. More on that later.
6. Uninstall App and Retry
Next, consider deleting and reinstalling the problematic app. To do that, open the Settings app and tap General > iPhone Storage to reveal a list of iPhone apps. Then, tap Delete App (or Offload App if there’s a substantial amount of downloaded video files you don’t want to lose). Follow that by searching for and reinstalling the app via the App Store.
Note: iOS restricts you from removing the Photos app. As a workaround, go to Settings > Photos and toggle iCloud Photos off, then on. Also, if your iPhone’s storage has sufficient free space, select the Download and Keep Originals option to cache your photo library locally.
7. Download a Compatible App
Suppose you have trouble playing a video clip you downloaded using Safari on another web browser. In that case, it might be in a video format that your iPhone does not natively support—e.g., MKV or AVI. A dedicated media player like VLC Player will allow you to start playing it.
To open an incompatible video file format on a different app, attempt to open the file in the Files app. Then, tap the Share icon and select the app on the Share Sheet.
Alternatively, a video converter on a PC or Mac can re-encode videos in an iPhone-compatible format like HEVC, MOV, or MPEG.
8. Delete Corrupt Downloads and Retry
Downloaded videos can sometimes corrupt and refuse to play. The only fix, in that case, is to delete and redownload them.
For example, switch to the Downloads tab on Netflix, tap the Edit icon, and the Delete icon next to a movie or episode you want to remove. Then, download the video again or stream it.
9. Clear Browser Cookies and Cache
If an online video has trouble loading or playing in Safari, a corrupt browser cache might be the source of the issue. Clearing the cookies and cache might help, so go to Settings > Safari and tap Clear History and Website Data.
Do you use a different web browser? Learn how to clear the cache in any browser on iPhone.
10. Install System Software Updates
An outdated version of iOS can also cause video playback and other issues on the iPhone. To update iOS to its latest version, open the Settings app and tap General > Software Update > Download & Install.
On the flip side, beta releases of iOS are often plagued with severe bugs and other problems. If you’re enrolled in the Apple Beta Software Program, we recommend you downgrade your iPhone to the stable channel.
11. Reset Your iPhone’s Settings
If the video playback problems on your iPhone persist, it’s time to factory reset the network settings on your iPhone. Often, that fixes an incorrect network setup preventing videos from playing.
To do that, open the Settings app and tap General > Transfer or Reset iPhone > Reset > Reset Network Settings. Then, enter your device passcode and tap Reset Network Settings again to confirm. After the settings reset, manually join a Wi-Fi network and attempt to play a video again.
If resetting the network settings doesn’t make a difference, revisit the same screen above but select the Reset All Settings option instead. That reverts all iPhone settings to their defaults and helps resolve deeper underlying conflicts that could be preventing your iPhone from playing videos.
Grab the Popcorn
iPhone video-related issues are bound to crop up at one point or another, but the reasons are pretty much the same each time, and the fixes above should help you get through them. Don’t forget to bookmark this tutorial so you can get to it quickly if you ever need to.
