获取上传的音频/视频文件的持续时间

Question

I want to get the duration of audio/video files that are being uploaded into the system. Earlier I had used hachoir-metadata , but it's not maintained anymore I guess, as there is no python 3 compatible module for that.

• IS there any other light weight alternative to it?
• In case if I wish to write something of my own to do it, what would be the prerequisites?

Answer 1

For anyone looking for this particular thing, follow following steps:

• Make sure you have libav-tools package installed. You can check it by typing and trying to execute avconv command. If not present, do sudo apt-get install libav-tools
• Then, try this command ffmpeg -i myvideo 2>&1 | grep Duration | cut -d ' ' -f 4 | sed s/,// ffmpeg -i myvideo 2>&1 | grep Duration | cut -d ' ' -f 4 | sed s/,// ffmpeg -i myvideo 2>&1 | grep Duration | cut -d ' ' -f 4 | sed s/,// (I found this command here ).
• If you want to use it in python script, you can probably use subprocess module to your effect

Correct me if I am wrong somewhere

Answer 2

if you know about ffmpeg , you can use ffmpeg to read the audio or video, it will output the duration of audio or video

$ ffmpeg -i  "Gotye - Somebody That I Used To Know (feat. Kimbra) - official video.mp4" 2>&1 | grep -E -o "Duration: \S+" 
Duration: 00:04:03.90,
