用 ffmpeg 剪切片段1、

ffmpeg -ss 44:26 -to 45:00 -i %file% -vf scale=-1:720 -c:v hevc_amf -c:a copy -c:s copy 1.mkv
nclick="copycode($('code1'));">復制代碼

包含視頻和第一個音軌，但是字幕全丟失2、

ffmpeg -ss 44:26 -to 45:00 -i %file% -vf scale=-1:720 -map 0:v:0 -c:v hevc_amf -map 0:a:1 -map 0:s:91.mkv

會報錯：Error initializing output stream 0:2 -- Subtitle encoding currently only possible from text to text or bitmap to bitmap請問，pgs字幕該怎么處理？謝謝！
