In order to draw Timestamp: 01:25., you should specify this one to (feed) ffmpeg: drawtext = text = 'Timestamp\: %{pts\:gmtime\:0\:%M\\\:%S}.' Don'tIf you specify this one to (feed) ffmpeg: drawtext = text = '%{pts\:gmtime\:0\:%M\\:%S}', it gives Unterminated %{} near '{pts:gmtime:0:%M\' error. But in bashBut if you're using bash-like shell and a weak quote, "......", to feed it, \\ is escaped to \, and \: is not escaped but remains without any changes because \: is not an escape sequence. So it should be: -filter_complex "drawtext = text = '%{pts\:gmtime\:0\:%M\\\\\:%S}'"i.e. bash's "\\\\\:" for ffmpeg's \\\: for getting a single character : displayed. Note thatIf you only want to apply one or more filters to one video stream (e.g, drawtext), you can use -vf instead of using --filter_complex. The latter is reserved for applying filters on multiple streams. (责任编辑：) |
