Describe the bug some usage I use it below cause different results.

1.  FFmpegOutputBuilder outputBuilder = new FFmpegBuilder()
                .addInput(filePath)
                .overrideOutputFiles(true)
                .addOutput( output)
                .disableVideo()
                .disableSubtitle()
               .setAudioChannels(1)
               .setAudioSampleRate(16000)
               .setFormat("s16le");

fFmpegExecutor.createJob(outputBuilder.done()).run();

Then i find build execute comand is ffmpeg -y -v error -i test.pcm -f s16le -vn -ac 1 -ar 16000 -sn test.wav, unfortunately i got error `test.pcm: Invalid data found when processing input.

  2. ffmpeg.run("-y",  "-f", "s16le", "-ar", "16000", "-ac", "1", "-i", "test.pcm", "test.wav");

In the usage 2 i found the convert success file test.wav and i can play it. so I guess it's the position of the parameters affects the command execute.

@Yogurt-lei you can use Jaffree. It separates parameters per each input/output
