InputStream instead of File

[AeonDave]

Hello!
how can i use an InputStream as input in the "setInput" option?
like defined in the audiowaveform example:
$ ffmpeg -i test.mp4 -f wav - | audiowaveform --input-format wav --output-format dat -b 8 > test

thank you

Hello @AeonDave ,
Currently only objects from type java.io.File can be passed as parameter for the "setInput" function. As a workaround you could write the inputstream into an temporary File object and pass this into the function...

hello and Thank you!
it's a good workaround for the input, but how to use the output as string?
exactly as in the example above: "--output-format", if format is json, no file is created and there is only an array of numbers.
thank you for your work

Hi @AeonDave,
you can define the output to be a json file via setOutput(new File("path/to/myJsonOutput.json")) function. You could then read the json output file with for example Jacksons ObjectMapper class to an string or java class.

Hope this helps!
