ffmpeg -ss 52:50 -to 57:48 -i dh.mkv -map 0:v: -c:v copy -map 0:a:1 -c:a copy -map 0:s:0 -c:s copy dhtest.mkv -y
以上的截取命令,用FFMPEG4.0才可以,其它版本都不行
不同版本差异很大,有时要用低版本,有时要用新的.
低版本对字幕比较友善.
我目前用2016年2和9月,
2017年4月,3.2
2018年月的4.0
这4个版本

能发一下用别的版本执行你的那行命令时的报错吗

嗯，这是因为-ss -to写到-i前面，貌似只有4.0支持这个操作，但是如果写到-i后面那么低版本也不会报错，但是就会导致从头解码到制定位置……
还是新版好

Good. 以前就是因为要从头解码，浪费了不少时间。

一般我开头都是一分钟 等得起
