[小脚本] python 制作视频字幕

Posted 2022-01-12 长虹剑

字幕分为两种
一种可以直接写在视频中，另一种制作srt，然后播放器就可以自动打开

from _chj.comm.pic import *

for i, line in enumerate( tqdm(readlines("data/qa_v_subtitle/text.txt")) ):
    fiv = f"data/qa_video/i+1:04d.mp4"

    #fsub= f"data/qa_v_subtitle/i+1:04d.srt"
    fsub= f"data/qa_video/i+1:04d.srt"
    cap = cv.VideoCapture(fiv)
    tm = cap.get(7) / 25
    #td =  datetime.fromtimestamp(tm) - datetime.fromtimestamp(0)
    td =  timedelta( seconds=tm )
    #print(td)
    hour = td.seconds//3600
    minute = (td.seconds//60)%60
    second = td.seconds % 60
    microsecond = td.microseconds
    tp="\\\\an8"
    ss = f"hour:02d:minute:02d:second:02d,microsecond//1000:03d"
    ss = f"1\\n00:00:00,0 --> ss\\ntpline\\n"
    with open(fsub, "w") as fp:
        fp.write(ss)
    
    cmd=f"ffmpeg -y -loglevel error -i fiv -vf subtitles=fsub fov"
    #cmd=f"cp fiv fov"
    exec_cmd(cmd)
