How to download video by url using ffmpeg-python

I'm trying to write script that will be downloading part of youtube video by url. I'm using ffmpeg + ffmpeg-python library.

I have terminal command that I want put to python code.

ffmpeg -i "url_to_download" -ss 00:00:15 -t 00:00:25 -c:v copy -c:a copy "demo.mp4"

url_to_download is an youtube stream url that I get like in an answer to another question https://stackoverflow.com/a/57134397/6583203

I started writing script

import ffmpeg

FROM = "00:00:15"
TO = "00:00:25"
TARGET = "demo.mp4"

ffmpeg.input(url_to_download, ss=FROM, t=TO)

But I don't know how to pass parameters -c:v copy -c:a copy "demo.mp4" to ffmpeg.input

Do not advice me to use subprocess. I have the same error like in a following question: Python ffmpeg won't accept path, why?

Solution

  • This answer worked for me

    ffmpeg.input(url_to_download, ss=FROM, t=TO).output("demo.mp4", vcodec="copy", acodec="copy").overwrite_output().run()
