如何使用从相机捕获的动画存储文本 [英] How to store a text with the animation captured from the camera

问题描述

我们需要使用从相机捕获的动画存储相应的文本。



请帮助....

解决方案

因为问题是关于SQL ...将它存储在视频，在另一栏中。



当然，你可以修改视频文件并在那里添加一些文字，但这取决于许多不同的因素：使用一些视频标准容器，用于存储元数据的编解码器，字幕或类似的东西，兼容性。



如果你还想这样，请请参阅：

对于视频文件的操作，我强烈推荐开源库和实用程序FFmpeg或相关的libavcodec：

解决方案

As the question is about SQL… store it outside the video, in a separate column.

Of course, you can modify the video file and add some text there, but then it depends on many different factors: use of some video standard container, codecs for storing metadata, captions or something like that, compatibility.

If you still want to go this way, please see:

For manipulation with video files, I would strongly recommend open-source libraries and utilities FFmpeg or related libavcodec:

http://libav.org/[^].
