I am iterating through a directory and running ffprobe
against each file to get it's duration. However, the only output I get is
b''
b''
Below is the part of the code I am using,
for y in filename:
p1 = subprocess.Popen (['ffprobe', '-i', y, '-show_entries', 'format=duration', '-sexagesimal', '-v', 'quiet', '-of', 'csv=%s' % ("p=0")], stdout=subprocess.PIPE).communicate()[0]
print (p1)
Currently, the directory I am iterating through has two files in it.
Any ideas how to get the actual duration printed please?
Thanks.
import subprocess
import glob
for y in glob.glob("*.mkv"):
p1 = subprocess.check_output(
[
"ffprobe",
"-i",
y,
"-show_entries",
"format=duration",
"-sexagesimal",
"-v",
"quiet",
"-of",
"csv=%s" % ("p=0"),
],
encoding="utf-8",
).strip()
print(y, p1)
works fine for me. (That is, using check_output()
and adding the encoding
parameter.)
The result is
2018-02-19T00:01.mkv 0:17:47.120000
as expected.

If your internal command is correct, the way to get subprocess output is as so:
p1 = subprocess.run(['ffprobe', '-i', y, '-show_entries', 'format=duration', '-sexagesimal', '-v', 'quiet', '-of', 'csv=%s' % ("p=0")], shell=True, capture_output=True).stdout
