ffmpeg-progress

This script is based on the work of Rupert Plumridge.

Basic use

import subprocess as sp
import sys

from ffmpeg_progress import start


def ffmpeg_callback(infile: str, outfile: str, vstats_path: str):
    p = sp.Popen(['ffmpeg',
                  '-y',
                  '-vstats_file', vstats_path,
                  '-i', infile,
                  outfile], stdout=sp.PIPE, stderr=sp.PIPE)
    return p.pid


def on_message_handler(percent: float,
                       fr_cnt: int,
                       total_frames: int,
                       elapsed: float):
    sys.stdout.write('\r{:.2f}%'.format(percent))
    sys.stdout.flush()


def on_done_handler():
    print('')


start('my input file.mov',
      'some output file.mp4',
      ffmpeg_callback,
      on_message=on_message_handler,
      on_done=on_done_handler,
      wait_time=1)  # seconds

start() is the main function to use. If on_message is not passed, a default function is used.

ffprobe

An ffprobe front-end function is included. Usage:

from ffmpeg_progress import ffprobe


ffprobe('my file.mp4')  # returns a dict()
