Using ffmpeg to obtain video durations in python

Question

I\'ve installed ffprobe using the pip ffprobe command on my PC, and installed ffmpeg from here.

However, I\'m still having trouble running the code listed here.

Answer 1

There is no need to iterate though the output of FFprobe. There is one simple command which returns only the duration of the input file:

ffprobe -v error -show_entries format=duration -of default=noprint_wrappers=1:nokey=1 

You can use the following method instead to get the duration:

def get_length(input_video):
    result = subprocess.run(['ffprobe', '-v', 'error', '-show_entries', 'format=duration', '-of', 'default=noprint_wrappers=1:nokey=1', input_video], stdout=subprocess.PIPE, stderr=subprocess.STDOUT)
    return float(result.stdout)
