如何从JPEG文件列表创建视频？ [英] How can I create a video from a list of JPEG files?

问题描述

我做过搜索，只有Windows Media Encoder Series 9 ，我不知道DirectX 是否也可以这样做，但是找不到任何方式学习它我甚至试过本教程，但我不能运行应用程序，它给我一个错误（我安装了Windows Media Encoder Series 9 和SDK）。

I did search and all I got is Windows Media Encoder Series 9 and I am not sure if DirectX can also do it, but I can't find any way to learn it. I even tried this tutorial but I can' t run the application, it gives me a bug (I did install Windows Media Encoder Series 9 and the SDK).

我的应用程序现在正在使用定时器在 PictureBox 中运行JPEG文件，但一分钟的大小约为20 MB，这不太好。我需要每天保存一整天！

My application is now running JPEG files in a PictureBox with a timer, but the size of one minute is about 20 MB and that is not good. I need to save the whole day every day!

我发现这个软件，它使用Windows Media Encoder，一分钟的视频大约是1 MB，这是非常好的，现在我知道可以将桌面记录到一个视频文件，但我该怎么办？我需要一步一步的解释或录像来教导我。

I found this software, it uses Windows Media Encoder and the video of one minute is about 1 MB which is great, now I know it's possible to record the desktop to a video file but how can I do it? I need a step by step explanation or videos to teach me.

推荐答案

该工具 ffmpeg 是完成这项工作的完美选择。他们的文档具有确切过程的示例您正在努力。

The tool ffmpeg is perfect for doing this job. Their documentation has a example of the exact process you are trying to do.

从许多图像创建视频：

For creating a video from many images:

ffmpeg -f image2 -i foo-%03d.jpeg -r 12 -s WxH foo.avi

语法 foo-％03d.jpeg 指定使用由
组成的十进制数，三位数填充为零表示序列号。它是
与C printf函数支持的相同语法，但只有格式
接受正常整数是合适的。

The syntax foo-%03d.jpeg specifies to use a decimal number composed of three digits padded with zeroes to express the sequence number. It is the same syntax supported by the C printf function, but only formats accepting a normal integer are suitable.

当导入图像序列时，-i还支持在内部扩展
类似shell的通配符模式（globbing），方法是选择
image2 -pattern_type glob选项。

When importing an image sequence, -i also supports expanding shell-like wildcard patterns (globbing) internally, by selecting the image2-specific -pattern_type glob option.

例如，创建与glob
模式相匹配的文件名的视频 foo - *。jpeg ：

For example, for creating a video from filenames matching the glob pattern foo-*.jpeg:

ffmpeg -f image2 -pattern_type glob -i 'foo-*.jpeg' -r 12 -s WxH foo.avi

只需每天运行，它会将您的文件夹全部转换成图像进入.avi文件，您可以在完成后删除图像。

Just run this daily and it will convert your folder full of images in to a .avi file and you can delete the images when you are done.
