Form that log, each video conversion log is divided in section, separated by the repeated dash. I'm trying to get the source full file name that failed to convert, in this case, C:\source\vid2.mp4 and C:\source\vid3.mp4. Using this regex pattern below however, I get one matched result (vid3.mp4) and one mismatched (vid1.mp4), it matches from line 6 Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'C:\source\vid1.mp4': to the end of the log.
(?sm)Input #(?<number>\d+).*?from '(?<filename>.*?)'.*?[A-Za-z]ailed to
任何想法如何解决这个问题？提前致谢。
