# Better FFmpeg Progress

Runs an FFmpeg command and uses [Rich](https://github.com/Textualize/rich) to show a progress bar.

</div>

## Example:

```
⠏ Processing abc.webm ━━━━━━━━━╺━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━  23% 0:00:04 00:15
```

Where:
- `Processing abc.webm` is the description of the progresss bar.
- `23%` is the percentage progress.
- `0:00:04` is the time (H:MM:SS) elapsed.
- `00:15` is the estimated time until the FFmpeg process completes.

## Installation:

```
pip install better-ffmpeg-progress --upgrade
```

## Usage:

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

Simple Example:

```py
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:

```py
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"])

# Use the run method to run the FFmpeg command.
process.run(
    output_file="ffmpeg_output.txt",
    progress_bar_description="Converting file...",
    progress_handler=handle_progress_info,
    success_handler=handle_success,
    error_handler=handle_error,
)
```

The `run` method takes the following **optional** arguments:
- `progress_bar_description` - An optional string to set a custom description for the progress bar. The default description is `Processing <file>`. This can be an empty string if you don't want the progress bar to have a description.

- `progress_handler`

  - You can create a function if you would like to do something with the following values:

    - Percentage progress. [float]
    - Speed, e.g. `22.3x` which 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 `None` if unknown. The function will receive the current values of these metrics as arguments, every 0.1s.

- `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.

## Changelog:

[19/09/2022]

- Add the ability to specify a `success_handler` argument, a function to run if the FFmpeg process completes successfully.
- Add 0.001 to tqdm's `total` parameter to prevent the chance of getting `TqdmWarning: clamping frac to range [0, 1]`

[21/12/2022]

- [v2.0.7] Fix `'estimated_size' referenced before assignment` error.
- [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_handler` argument, a function to run if the FFmpeg process encounters an error.
- [v2.0.9] Fix a typo (commit [da45a84](https://github.com/CrypticSignal/better-ffmpeg-progress/commit/da45a8416856ab7d3c7b748db5703fa3dbc65f60))

[05/11/2023]

- [v2.1.2] [Do not exit the Python interpreter after the FFmpeg process is complete](https://github.com/CrypticSignal/better-ffmpeg-progress/commit/0a358810773835297faae688689c6e0d8a5859ae)
