better-ffmpeg-progress 1.2.9

Run FFmpeg & see percentage progress + ETA.

better-ffmpeg-progress

Runs an FFmpeg command and shows the following in the terminal:

• Percentage Progress
• Speed
• ETA (minutes and seconds)

Example: Progress: 25% | Speed: 22.3x | ETA: 1m 33s

Installation:

pip3 install better-ffmpeg-progress

Usage:

Create an instance of the FfmpegProcess class and supply a list of arguments like you would to subprocess.run()

from better_ffmpeg_progress import FfmpegProcess
# Pass a list of FFmpeg arguments, like you would if using subprocess.run()
process = FfmpegProcess(["ffmpeg", "-i", "input.mp4", "-c:a", "libmp3lame", "output.mp3"])
# Use the run method to run the FFmpeg command. The progress information will be printed in the terminal.
process.run()

The run method takes the following optional arguments:

• progress_handler

  • You can create a function if you wish to do something specific with the percentage progress, speed and ETA rather than it being printed in the format Progress: 25.6% | Speed: 22.3x | ETA: 1m 33s. The function will receive:
    • percentage progress (float, 1 decimal place), e.g. 25.6.
    • Speed (string), e.g. 22.3x.
    • ETA in seconds (float), e.g. 4.68984375.

  Here's an example:

  def handle_progress_info(percentage, speed, eta):
      print(f"The FFmpeg process is {percentage}% complete. ETA is {eta} seconds based on the current speed ({speed}).)
  

  Then you simply set the value of the progress_handler argument to the name of your function, like so:

  process.run(progress_handler=handle_progress_info)
  

• ffmpeg_output_file

  • The ffmpeg_output_file argument allows you define where you want the output of FFmpeg to be saved. By default, this is saved in a folder named "ffmpeg_output", with the filename [<input_filename>].txt, but you can change this using the ffmpeg_output_file argument.

Here's an example where both the progress_handler and ffmpeg_output_file parameters are used:

process.run(progress_handler=handle_progress_info, ffmpeg_output_file="ffmpeg_log.txt")
