39%|███████████████████████████████████████████ | 23.6/60.2 [00:19<00:34, 1.07s/s]
Where:
39%is the percentage progress.23.6seconds of the input file have been processed.60.2is the duration of the input file in seconds.00:19is the time elapsed since the FFmpeg process started.00:34is the estimated time required for the FFmpeg process to complete.1.07shows how many seconds of the input file are processed per second.
pip3 install better-ffmpeg-progress --upgrade
Create an instance of the FfmpegProcess class and supply a list of arguments like you would to subprocess.run().
Simple Example:
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.
process.run()Advanced Example:
from better_ffmpeg_progress import FfmpegProcess
def handle_progress_info(percentage, speed, eta, estimated_filesize):
print(f"Estimated Output Filesize: {estimated_filesize / 1_000_000} MB")
def handle_success():
# Code to run if the FFmpeg process completes successfully.
pass
def handle_error():
# Code to run if the FFmpeg process encounters an error.
pass
# Pass a list of FFmpeg arguments, like you would if using subprocess.run()
process = FfmpegProcess(["ffmpeg", "-i", "input.mp4", "-c:a", "libmp3lame", "output.mp3"])
ffmpeg_output_path = 'ffmpeg_output.txt'
# Use the run method to run the FFmpeg command.
process.run(progress_handler=handle_progress_info, ffmpeg_output_file=ffmpeg_output_path, success_handler=handle_success, error_handler=handle_error)The run method takes the following optional arguments:
-
progress_handler-
You can create a function if you would like to do something with the following values:
- Percentage progress. [float]
- Speed, e.g.
22.3xwhich means that 22.3 seconds of the input are processed every second. [string] - ETA in seconds. [float]
- Estimated output filesize in bytes. [float]
- Note: This is not accurate. Please take the value with a grain of salt.
The values will be
Noneif unknown. The function will receive the aforementioned metrics as arguments, about two times per second.
-
-
ffmpeg_output_file- A string path to 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. -
success_handler- A function to run if the FFmpeg process completes successfully. -
error_handler- A function to run if the FFmpeg process encounters an error.

- Add the ability to specify a
success_handlerargument, a function to run if the FFmpeg process completes successfully. - Add 0.001 to tqdm's
totalparameter to prevent the chance of gettingTqdmWarning: clamping frac to range [0, 1]
[21/12/2022]
- [v2.0.7] Fix
'estimated_size' referenced before assignmenterror. - [v2.0.7] The progress bar now uses 1 decimal place for seconds processed and total duration.
[22/12/2022]
- [v2.0.8] Add the ability to specify an
error_handlerargument, a function to run if the FFmpeg process encounters an error. - [v2.0.9] Fix a typo (commit da45a84)
[07/02/2022]
- [v2.1.0] Update function name to fix
'process_complete_handler' is not definederror.
