ffmpeg 多输入文件seek操作

lexico

截取指定时间区间内 视频片段和背景音乐片段，如何一个命令搞定， ffmpeg 好像不能每一个输入文件执行seek 操作

ffmpeg -i QZmONF09A8RvzNxNZqL.mp4 -ss 10 -to 40 -i xinyang.mp3  -ss 60 -to 100  -filter_complex "subtitles=xinyang.lrc[v]" -map "[v]" -map 1:a -s 640x360 -c:a aac -shortest -copyts output2.mp4

谢谢大师兄，硬编码字幕时候遇到个问题 ，命令行如下 导致字幕压不进去 中文字幕乱码，是什么原因
./ffmpeg -loglevel info -report -hide_banner -y -ss 5 -t 40 -i QZmONF09A8RvzNxNZqL-zpYs-IO9K33kKbSqiQ___32.mp4 -ss 40 -t 80 -i xinyang.mp3 -filter_complex "[0:v]subtitles=/data/transcode/2019-09-11/1592198/xinyang.lrc[v];[0:a][1:a]amix=inputs=2[a]:weights=1 2[a]" -map "[v]" -map "[a]" -c:v libx264 -profile:v high -crf 23 -c:a libfdk_aac -shortest test.mp4
