如何使用FFmpeg在秒之间切换视频？

Question

例如：

startMs = 2.4. 
endMs = 5.4 
I have tried this code: 
String[] complexCommand = {"-i", yourRealPath, "-ss", "" + startMs, "-acodec", "copy", "-vcodec", "copy", "-t", "" + (endMs - startMs), dest.getAbsolutePath()}; 

但切削过程发生具有完全值（INT值）...从“秒2”至“5秒”
是否有任何方式削减视频与“浮点值“？
谢谢

你不能使用时间戳吗？喜欢的东西：

String startMs = "00:00:02.400"; 
String endMs = "00:00:05.400"; 
Srting totalMs = "00:00:03.000"; 

String[] complexCommand = {"-i", yourRealPath, "-ss", "" + startMs, "-acodec", "copy", "-vcodec", "copy", "-t", "" + (endMs - startMs), dest.getAbsolutePath()};

您可能需要适应的东西，现在我无法测试它，但它是woth一试。祝你好运！
