Java H265視頻抽幀提取照片

• • 1. Windows下可調用ffmpeg.exe實現，親測可行
  • 2. linux下調用FFmpegFrameGrabber
  • 3. 源碼
  • 4. 效果圖
  • 5. pom依賴
  • 參考：

1. Windows下可調用ffmpeg.exe實現，親測可行

• 可以直接執行命令行

# 把目錄下視頻——E:\\data\\test.h265抽幀每一幀為圖片，并命名為1.jpg，2.jpg，3.jpg...存儲在E:\\data\\test\\images\\文件夾
ffmpeg.exe -y -i E:\\data\\test.h265 -ss 00:00:00 -f image2 -vsync 2 E:\\data\\test\\images\\%d.jpg

前提需要目錄E:\data\test\images\存在；

• 可以Java ProcessBuilder調用如上命令行實現；

2. linux下調用FFmpegFrameGrabber

• 調用跨平臺的ffmpeg
• python代碼打包成linux平臺可調用的二進制文件
• 推薦優雅的方案：FFmpegFrameGrabber

3. 源碼

包括

• ffmpeg.exe windows支持，linux需要自己配置ffmpeg
• FFmpegFrameGrabber，跨平臺，支持windows，支持linux
  倆個的實現源碼如下：
