ffmpeg output to multiple files simultaneously

Question

What format/syntax is needed for ffmpeg to output the same input to several different "output" files? For instance different formats/different bitrates? Does it support parallelism on the output?

Answer 1

The ffmpeg documentation has been updated with lots more information about this and options depend on the version of ffmpeg you use: http://ffmpeg.org/trac/ffmpeg/wiki/Creating%20multiple%20outputs

Answer 2

From FFMpeg documentation, FFmpeg writes to an arbitrary number of output "files".

Just make sure each output file (or stream), is preceded by the proper output options.
