How to Extract Duration Time from Ffmpeg Output

How to extract duration time from ffmpeg output?

ffmpeg is writing that information to stderr, not stdout. Try this:

ffmpeg -i file.mp4 2>&1 | grep Duration | sed 's/Duration: \(.*\), start/\1/g'

Notice the redirection of stderr to stdout: 2>&1

EDIT:

Your sed statement isn't working either. Try this:

ffmpeg -i file.mp4 2>&1 | grep Duration | awk '{print $2}' | tr -d ,

Using ffmpeg to obtain video durations in python

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 <input_video>

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)

How to find duration of a video file using mediainfo in seconds or other formats?

Use the following commands:

i) To get the duration of video stream:

$ mediainfo --Inform="Video;%Duration%"  [inputfile]

ii) To get the duration of the media file:

$ mediainfo --Inform="General;%Duration%" [inputfile]

iii) To get the duration of audio stream only:

$ mediainfo --Inform="Audio;%Duration%" [inputfile]

iv) To get values of more than one parameter:

$ mediainfo --Inform="Video;%Width%,%Height%,%BitRate%,%FrameRate%" [inputfile]

Output would be something like this:

1280,720,3000000,30.0

How to get video duration in seconds?

2383 is correct. There are 60 seconds in a minute, not 100. 43/60 = .71

How to get the real, actual duration of an MP3 file (VBR or CBR) server-side

I finally found a proper solution to this problem using sox - which returns the correct information.
