I created a subclass called
FFMpegInputBuilderwhich extends theAbstractFFmpegStreamBuilder. Seeing that theAbstractFFmpegInputBuilderwas designed for outputs, I re-implemented the filename property and build method to retain all previous functionality.I also added tests to see that the inputs are built properly, modelled after #156 . I added a convenience method to parse commands separated by spaces for assertion purposes.
From the
FFmpegBuilder, you simply calladdInputStream(String inputStream)to build the input.
