Giving ffmpeg options defeats the purpose

[lodenrogue]

Giving the command line options like below defeats the purpose of having a python wrapper for FFmpeg:

>>> ff = FFmpeg(
...     inputs={'input.ts': None},
...     outputs={'output.mp4': '-c:a mp2 -c:v mpeg2video'}
... )

and

>>> ff = FFmpeg(
...     inputs={'input.ts': None},
...     outputs={
...         'video.mp4': ['-map', '0:0', '-c:a', 'copy', '-f', 'mp4'],
...         'audio.mp4': ['-map', '0:1', '-c:a', 'copy', '-f', 'mp4']
...     }
... )

Instead consider using an object oriented approach to do the same thing:

input = InputBuilder(fileName)
    .codec(codec)
    .filter(filter)
    ... etc
    .build()
    
ff = FFmpeg(
    inputs = [input],
    outputs = [output]
)

ff.run()

With this approach you gain the following:

1. Hide away the implementation details of ffmpeg
2. Allow the user to work at a higher level of abstraction
3. Remove the need to understand both ffmpeg and your wrapper
4. Abstract complex behavior behind simple interfaces
