How to get the start time, end time in seconds from YouTube timestamp using python?-CodePudding

I'm having a list of timestamps of a YouTube video.

Example:

timestamps = ['0:02-0:35', '0:50-1:18', '2:53-3:08', '3:12-3:14', '3:16-3:22', '3:25-3:28', '1:09-1:35', '1:38-1:48', '2:04-2:14', '2:30-2:40', '2:45-2:50', '3:35-4:07', '4:16-4:22', '4:48-4:54', '5:00-5:12', '5:34-5:54', '8:58-9:19', '']

Now I need to fetch the starttime and endtime for each timestamp in seconds since I need to pass these as arguments for ffmpeg_extract_subclip method to cut a video into sub clips.

for example,

# If the timestamp is 0:02-0:35 The starttime and endtime should be,
timestamp = '0:02-0:35'
starttime = 2
endtime = 35

# If the timestamp is 3:02-3:35 The starttime and endtime should be,
timestamp = '3:02-3:35'
starttime = 182 # [(3 * 60)   2]
endtime = 215 # [(3 * 60)   35]

Can we do it with regex? or Is there any other options?

CodePudding user response：

You can do it with regex, capturing the minutes (\d{1,2}) and seconds(\d{2}) from the source string.

import re
interval = '0:02-0:35'
start_min, start_sec, end_min, end_sec = map(int, re.findall('\d{1,2}', interval))

or split time by : and - via re.split.

start_min, start_sec, end_min, end_sec = map(int, re.split('[:-]', interval))

But you can also simply do it by a built-in function str.split.

start_min, start_sec, end_min, end_sec = (int(t) for time in interval.split('-') for t in time.split(':'))
