Voglio impostare lo stream start su 0, ma il file di input TS non è start 0. Quindi uso manualmente il filtro setpt impostando start. Come impostare gli opitoni usando il filtro setpts?
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"
