基于函数计算和FFmpeg处理音视频
更新时间: 2024-10-16 09:50:46
使用Serverless Devs开发工具可以快速部署基于函数计算、对象存储OSS和FFmpeg的应用，帮助您处理音视频，例如获取音视频信息、给音视频添加水印及转换格式等。
背景信息
FFmpeg是一套可以记录、转换数字音视频，并将其转化为流的开源计算机程序。FFmpeg采用LGPL或GPL许可证，提供了录制、转换和流化音视频的完整解决方案，包括先进的音视频编解码库libavcodec，并且保证了高可移植性和编解码质量。详细信息，请参见FFmpeg。
本文以Python语言为例，介绍的示例模板中包含以下主题。您也可以根据实际需求修改给到示例的函数代码实现二次开发。
示例名称 | 描述 |
GetMediaMeta | 获取音视频的Meta信息。 |
GetDuration | 获取音视频的时长。 |
GetSprites | 将视频制作成雪碧图。 |
VideoWatermark | 添加文字水印、静态图片水印和动态GIF水印。 |
AudioConvert | 转换音视频格式。 |
VideoGif | 将Video格式提取成GIF格式。 |
前提条件
使用Serverless Devs部署应用
执行以下命令，初始化项目。
sudo s init ffmpeg-app-v3 -d ffmpeg-app-v3-d用于指定生成的目录的名称。执行以下命令，进入项目目录。
cd ffmpeg-app-v3可选：您可以按需修改项目目录中的代码示例，实现您的业务逻辑。
执行以下命令，部署项目。
sudo s deploy -y说明如果您只需要部署该项目内的某个功能，例如需要部署GetMediaMeta功能获取音视频的Meta信息。请执行以下命令：
sudo s GetMediaMeta deploy当您需要部署其他功能时，请将
GetMediaMeta修改为其他功能的名称。部署完成后，输出示例如下。
