                ``` ffmpeg -ss 00:00:06 -t 00:00:12 -i input.mp4 -vcodec copy -acodec copy output.mp4 ``` 意思是從截取從6秒開始,時長為12秒的視頻,格式不變, 輸入為input.mp4 輸出為output.mp4 \-vcodec copy -acodec copy : 編碼格式不變 ***** 還有就是關于-s選項的解釋: ‘-ss position (input/output)’ When used as an input option (before -i), seeks in this input file to position. When used as an output option (before an output filename), decodes but discards input until the timestamps reach position. This is slower, but more accurate. position may be either in seconds or in hh:mm:ss\[.xxx\] form. 意思就是如果要把-ss作為輸入選項的話要放在-i之前,當做輸出選項的話放在輸出文件之前。我們這是要截取一段視頻,應該當做輸入選項,所以-ss要在-i之前才有效,不然會花費很長一段時間來尋找-ss。 作者:Gongjia 鏈接:https://www.jianshu.com/p/2975f4efd808 來源:簡書 簡書著作權歸作者所有,任何形式的轉載都請聯系作者獲得授權并注明出處。
