Per the fluent-ffmpeg documentation you should be able to use a ffmpeg command in an output option: outputOption() This method allows passing any output-related option to ffmpeg. For further explanation - ffmpeg can be used as a classic nix commandline tool with piping and to achieve that old classic usage it takes STDIN for input and writes output data to STDOUT. This._currentOutput.options('-map', spec.replace(utils.streamRegexp, '')) PIPE) The FFmpeg output held in subprocess stdout (p1.stdout) will then be passed to Boto3 Amazon.

The first process writes the output bitstream to stdout and the other process read the bitstream from stdin. Further information is available in the libvpx API documentation. One process to read and decode the input file and another process to generate the mpeg-ts stream. Testing has shown that running the first pass at maximum speed doesn’t degrade quality, so that’s the recommended approach. To get more documentation of the libvpx options, invoke the command ffmpeg -h encoderlibvpx, ffmpeg -h encoderlibvpx-vp9 or vpxenc -help. VP9 encoding speed ranges from 0 to 4, with 0 being the slow, high-quality option, and 4 being the fast, lowest-quality option (according to the FFmpeg help file, the default is 1).
