我想将流起始设置为 0，但输入的 TS 文件不是起始 0。然后我使用 setpts 过滤器手动设置起始。如何使用 setpts 过滤器设置选项？
ffprobe -loglevel quiet -select_streams 0:v -show_entries stream=start_time -of compact=p=0:nk=1 "F:\TS\input.ts" -v 0
72532.961778
and set 72532.961778 manually
ffplay -i "F:\TS\input.ts" -vf "setpts=PTS-72532.961778/TB,showinfo"

答案1
格式 start_time != stream start_time
获得价值
