Faced the same problem earlier and put together a simple Python script to do just that (using FFMpeg). Available here: https://github.com/c0decracker/video-splitter, and pasted below:
#!/usr/bin/env python
import subprocess
import re
import math
from optparse import OptionParser
length_regexp = 'Duration: (\d{2}):(\d{2}):(\d{2})\.\d+,'
re_length = re.compile(length_regexp)
def main():
(filename, split_length) = parse_options()
if split_length <= 0:
print "Split length can't be 0"
raise SystemExit
output = subprocess.Popen("ffmpeg -i '"+filename+"' 2>&1 | grep 'Duration'",
shell = True,
stdout = subprocess.PIPE
).stdout.read()
print output
matches = re_length.search(output)
if matches:
video_length = int(matches.group(1)) * 3600 + \
int(matches.group(2)) * 60 + \
int(matches.group(3))
print "Video length in seconds: "+str(video_length)
else:
print "Can't determine video length."
raise SystemExit
split_count = int(math.ceil(video_length/float(split_length)))
if(split_count == 1):
print "Video length is less then the target split length."
raise SystemExit
split_cmd = "ffmpeg -i '"+filename+"' -vcodec copy "
for n in range(0, split_count):
split_str = ""
if n == 0:
split_start = 0
else:
split_start = split_length * n
split_str += " -ss "+str(split_start)+" -t "+str(split_length) + \
" '"+filename[:-4] + "-" + str(n) + "." + filename[-3:] + \
"'"
print "About to run: "+split_cmd+split_str
output = subprocess.Popen(split_cmd+split_str, shell = True, stdout =
subprocess.PIPE).stdout.read()
def parse_options():
parser = OptionParser()
parser.add_option("-f", "--file",
dest = "filename",
help = "file to split, for example sample.avi",
type = "string",
action = "store"
)
parser.add_option("-s", "--split-size",
dest = "split_size",
help = "split or chunk size in seconds, for example 10",
type = "int",
action = "store"
)
(options, args) = parser.parse_args()
if options.filename and options.split_size:
return (options.filename, options.split_size)
else:
parser.print_help()
raise SystemExit
if __name__ == '__main__':
try:
main()
except Exception, e:
print "Exception occured running main():"
print str(e)
