Run FFmpeg & see percentage progress + ETA.
Project description
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
.
- percentage progress (float, 1 decimal place), e.g.
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 simple set the value of the
progress_handler
argument to the name of your function, like so:process.run(progress_handler=handle_progress_info)
- 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
-
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 theffmpeg_output_file
argument.
- The
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")
