Get progress information for an ffmpeg process.

Project description

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):
    return sp.Popen(['ffmpeg',
                     '-nostats',
                     '-loglevel', '0',
                     '-y',
                     '-vstats_file', vstats_path,
                     '-i', infile,
                      outfile]).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()


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

start() is the main function to use. If on_message is not passed, a default function is used. The on_done argument is optional. The initial_wait_time keyword argument can be used to specify a time to wait before processing the log.

The ffmpeg callback must return a PID (int). It is recommended to pass -nostats -loglevel 0 to your ffmpeg process. The ffmpeg callback also must pass -vstats_file given the path from the callback argument.

ffprobe

An ffprobe front-end function is included. Usage:

from ffmpeg_progress import ffprobe


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