Key Methods & Functions Guide
1. .input()
This method is used to specify the input source, which can be a file, stream, or other sources.
Usage:
stream = ffmpeg.input('path/to/input/file.mp4')
2. .output()
Designate the output destination for the processed data. This method also allows specifying codecs, formats, and other encoding parameters.
Usage:
ffmpeg.output(stream, 'path/to/output/file.mp4')
3. .run()
Execute the FFmpeg command with the specified input, filters, and output parameters. This method runs the constructed FFmpeg command in the background.
Usage:
ffmpeg.run(stream)
4. .filter()
This method applies a filter to the input stream. Filters can be used for tasks like resizing, cropping, and other transformations.
Usage:
filtered_stream = stream.filter('crop', out_w=640, out_h=360)
5. .overwrite_output()
By using this method, you can set FFmpeg to overwrite any existing files with the same name as the specified output.
Usage:
ffmpeg.output(stream, 'path/to/output/file.mp4').overwrite_output()
6. .view()
This method is particularly useful for debugging. It helps visualize the constructed filter graph.
Usage:
stream.view(filename='filter_graph.png')
