  1. 视频元数据提取方法

随着互联网的飞速发展，视频已成为人们获取信息、娱乐休闲的重要途径，在视频制作、传播、管理过程中，元数据起着至关重要的作用，元数据是描述视频信息的属性，如标题、作者、时长、分辨率等，本文将详细介绍如何提取视频中元数据的内容，并分享一些实用技巧。

视频元数据提取方法

1、利用第三方软件提取

市面上有许多专业的视频元数据提取工具，如MediaInfo、HandBrake等，这些软件支持多种视频格式，操作简单，功能强大，以下是使用MediaInfo提取视频元数据的步骤：

（1）下载并安装MediaInfo软件。

（2）打开MediaInfo，点击“File”菜单，选择“Open...”，然后选择要提取元数据的视频文件。

（3）软件会自动解析视频信息，并显示在界面左侧。

（4）点击左侧的“General”选项卡，即可查看视频的基本信息，如格式、编码、分辨率、时长等。

（5）点击“Stream”选项卡，可以查看视频中的音频、视频流信息。

2、利用编程语言提取

如果你对编程有一定了解，可以使用Python、Java等编程语言，结合相应的库（如moviepy、ffmpeg-python等）实现视频元数据的提取，以下是一个使用Python和moviepy库提取视频元数据的示例：

from moviepy.editor import VideoFileClip
获取视频元数据
def get_video_info(video_path):
    clip = VideoFileClip(video_path)
    video_info = {
        "duration": clip.duration,
        "size": clip.size,
        "fps": clip.fps,
        "audio_fps": clip.audio.fps,
        "audio_channels": clip.audio.channels,
        "audio_bits_per_sample": clip.audio.bits_per_sample,
    }
    clip.close()
    return video_info
调用函数
video_path = "example.mp4"
video_info = get_video_info(video_path)
print(video_info)

3、利用操作系统命令提取

部分操作系统提供了命令行工具，可以提取视频元数据，以下以Windows系统为例，使用cmd命令提取视频元数据：

（1）打开Windows命令提示符。

（2）输入以下命令：

for /f "tokens=2 delims=" %%i in ('wmic os get localdatetime /value') do set datetime=%%i
for /f "tokens=2 delims=" %%i in ('wmic os get localdatetime /value') do set datetime=%%i
