为 App Preview 捕捉 iOS 模拟器视频

Question

提问by AXE

Okay, so we can now submit video previews of our apps on the App Store. According to Apple we should do so with an iOS8 device and OSX 10.10.The problem is you have to have all the different devices (4", 4.7", 5.5" and iPad).

好的，现在我们可以在 App Store 上提交我们的应用程序的视频预览。根据 Apple 的说法，我们应该使用 iOS8 设备这样做，OSX 10.10.但问题是您必须拥有所有不同的设备（4"、4.7"、5.5" 和 iPad）。

Is there an alternative to this?

有没有替代方法？

I am thinking of capturing a video of the simulator. The problem is the device screen is bigger than my FullHDmonitor when shown in 100% resolution. Any solution that can capture a video right from the simulator in full resolution?

我正在考虑拍摄模拟器的视频。问题是设备屏幕FullHD以 100% 分辨率显示时比我的显示器大。任何可以从模拟器中以全分辨率捕获视频的解决方案？

Edit: Since a lot of people are answering questions I'm not asking let me say: - Recording one device size and scaling it is not what I'm asking; - How to record anyapp preview is not what I'm asking; - How you do your previews is not what I'm asking;

编辑：由于很多人都在回答我不是问的问题，所以我说： - 记录一种设备尺寸并对其进行缩放不是我要问的；- 如何记录任何应用程序预览不是我要问的；- 你如何进行预览不是我要问的；

What I amasking is can you record a video from the simulator in 100% resolution if it doesn't fit on the screen?

什么我问的是你可以记录从100％分辨率模拟器的视频，如果它不适合在屏幕上？

For Xcode 8.2 or later

对于 Xcode 8.2 或更高版本

You can take videos and screenshots of Simulator using the xcrun simctl, a command-line utility to control the Simulator

您可以使用xcrun simctl控制模拟器的命令行实用程序来拍摄模拟器的视频和屏幕截图

Run your app on the simulator
Open a terminal
Run the command
- To take a screenshot
  xcrun simctl io booted screenshot <filename>.<file extension>
  For example:
  xcrun simctl io booted screenshot myScreenshot.png
- To take a video
  xcrun simctl io booted recordVideo <filename>.<file extension>
  For example:
  xcrun simctl io booted recordVideo appVideo.mov
Press ctrl + cto stop recording the video.

在模拟器上运行你的应用
打开终端
运行命令
- 截屏
  xcrun simctl io booted screenshot <filename>.<file extension>
  例如：
  xcrun simctl io booted screenshot myScreenshot.png
- 拍摄视频
  xcrun simctl io booted recordVideo <filename>.<file extension>
  例如：
  xcrun simctl io booted recordVideo appVideo.mov
按ctrl + c停止录制视频。

The default location for the created file is the current directory.

创建的文件的默认位置是当前目录。

Xcode 11.2 and later gives extra options.

Xcode 11.2 及更高版本提供了额外的选项。

From Xcode 11.2 Beta Release Notes

来自 Xcode 11.2 Beta 发行说明

simctl video recording now produces smaller video files, supports HEIC compression, and takes advantage of hardware encoding support where available. In addition, the ability to record video on iOS 13, tvOS 13, and watchOS 6 devices has been restored.

simctl 视频录制现在生成更小的视频文件，支持 HEIC 压缩，并在可用的情况下利用硬件编码支持。此外，还恢复了在 iOS 13、tvOS 13 和 watchOS 6 设备上录制视频的功能。

You could use additional flags:

您可以使用其他标志：

xcrun simctl io --help
Set up a device IO operation.
Usage: simctl io <device> <operation> <arguments>

...

    recordVideo [--codec=<codec>] [--display=<display>] [--mask=<policy>] [--force] <file or url>
        Records the display to a QuickTime movie at the specified file or url.
        --codec      Specifies the codec type: "h264" or "hevc". Default is "hevc".

        --display    iOS: supports "internal" or "external". Default is "internal".
                     tvOS: supports only "external"
                     watchOS: supports only "internal"

        --mask       For non-rectangular displays, handle the mask by policy:
                     ignored: The mask is ignored and the unmasked framebuffer is saved.
                     alpha: Not supported, but retained for compatibility; the mask is rendered black.
                     black: The mask is rendered black.

        --force      Force the output file to be written to, even if the file already exists.

    screenshot [--type=<type>] [--display=<display>] [--mask=<policy>] <file or url>
        Saves a screenshot as a PNG to the specified file or url(use "-" for stdout).
        --type       Can be "png", "tiff", "bmp", "gif", "jpeg". Default is png.

        --display    iOS: supports "internal" or "external". Default is "internal".
                     tvOS: supports only "external"
                     watchOS: supports only "internal"

                     You may also specify a port by UUID
        --mask       For non-rectangular displays, handle the mask by policy:
                     ignored: The mask is ignored and the unmasked framebuffer is saved.
                     alpha: The mask is used as premultiplied alpha.
                     black: The mask is rendered black.

Now you can take a screenshot in jpeg, with mask (for non-rectangular displays) and some other flags:

现在你可以在中截取一张jpeg带有掩码（用于非矩形显示）和一些其他标志的屏幕截图：

xcrun simctl io booted screenshot --type=jpeg --mask=black screenshot.jpeg

I'm actually surprised no one provided my answer. This is what you do (this will work if you have at least 1 eligible device):

我实际上很惊讶没有人提供我的答案。这就是您要做的（如果您至少有 1 台符合条件的设备，这将起作用）：

Record, edit and finish the App Preview with the device you have.
Export as a file.
Go to your Simulators and print screen 1 shot on each the different sizes of iPhone.
Create new App Preview in iMovie.
Insert the screenshot of the desired size FIRST, then add the file of the App Preview you've already made.
Export using Share -> App Preview
Repeat step 4 to 6 for new sizes.

使用您拥有的设备记录、编辑和完成应用预览。
导出为文件。
转到您的模拟器并在每个不同尺寸的 iPhone 上打印屏幕 1。
在 iMovie 中创建新的应用程序预览。

iPhone Portrait

iPhone 人像

When you finished the recording, you can use iMovie to edit the video. When you're working on an iPhone Portrait App Preview, the resolution must be 1080x1920but iMovie can only export in 16:9(1920x1080).

完成录制后，您可以使用 iMovie 编辑视频。当您处理 iPhone Portrait App Preview 时，分辨率必须为，1080x1920但 iMovie 只能以16:9( 1920x1080)格式导出。

One solution would be to imported the recorded video with the resolution 1080x1920and rotate it 90 degree. Then export the movie at 1920x1080and rotate the exported video back 90 degrees using ffmpeg and the following command

一种解决方案是导入具有分辨率的录制视频并将其1080x1920旋转 90 度。然后1920x1080使用 ffmpeg 和以下命令导出电影并将导出的视频向后旋转 90 度

ffmpeg -i Landscape.mp4 -vf "transpose=1" Portrait.mp4

iPad

The iPad is a little bit trickier because it requires a resolution of 1200x900(4:3) but iMovie only exports in 16:9.

iPad 有点棘手，因为它需要1200x900( 4:3)的分辨率，但 iMovie 只导出16:9.

Here is what I've done.

这是我所做的。

Record the movie on iPad Air in Landscape (1200x900, 4:3)
Import into iMovie and export as 1920x1080, 16:9(iPadLandscape16_9-1920x1080.mp4)

Remove left and right black bars to a video with 1440x1080. The width of one bar is 240

ffmpeg -i iPadLandscape16_9-1920x1080.mp4 -filter:v "crop=1440:1080:240:0" -c:a copy iPadLandscape4_3-1440x1080.mp4

Scale down movie to 1220x900

ffmpeg -i iPadLandscape4_3-1440x1080.mp4 -filter:v scale=1200:-1 -c:a copy iPadLandscape4_3-1200x900.mp4

在 iPad Air 上以横向 ( 1200x900, 4:3)录制电影
导入 iMovie 并导出为1920x1080, 16:9( iPadLandscape16_9-1920x1080.mp4)

使用删除视频的左右黑条1440x1080。一根条的宽度是240

ffmpeg -i iPadLandscape16_9-1920x1080.mp4 -filter:v "crop=1440:1080:240:0" -c:a copy iPadLandscape4_3-1440x1080.mp4

将电影缩小到 1220x900

ffmpeg -i iPadLandscape4_3-1440x1080.mp4 -filter:v scale=1200:-1 -c:a copy iPadLandscape4_3-1200x900.mp4

You can do this for free with the following tools. You will need at least one real device (I used an iPhone 5)

您可以使用以下工具免费执行此操作。你至少需要一台真机（我用的是 iPhone 5）

Capture the video with the simple, but excellent appshow(note this is a very barebones tool, but it's very easy to learn). This will export at the native device resolution (640x1136).

使用简单但出色的appshow捕获视频（请注意，这是一个非常准系统的工具，但很容易学习）。这将以本机设备分辨率 (640x1136) 导出。

Resize with ffmpeg. Due to rounding, you can go directly between the resolutions, but you have to oversize and then crop.

使用 ffmpeg 调整大小。由于四舍五入，您可以直接在分辨率之间切换，但您必须放大然后裁剪。

ffmpeg -i video.mov -filter:v scale=1084:1924 -c:a copy video_1084.mov
ffmpeg -i video_1084.mov -filter:v "crop=1080:1920:0:0" -c:a copy video_1080.mov

For ipad, you can crop and then add a letterbox. However, cropping like this usually won't yield a video that looks exactly like your app does on the ipad. YMMV.

对于 ipad，您可以裁剪然后添加一个信箱。但是，像这样裁剪通常不会产生与您的应用在 ipad 上显示的完全相同的视频。天啊。

ffmpeg -i video.mov -filter:v "crop=640:960:0:0" -c:a copy video_640_960.mo
ffmpeg -i video_640_960.mov -filter:v "pad=768:1024:64:32" -c:a copy video_768_1024.mov
ffmpeg -i video_768_1024.mov -filter:v scale=900:1200 -c:a copy video_900_1200.mov
