Null muxer.
This muxer does not generate any output file, it is mainly useful for
testing or benchmarking purposes.
For example to benchmark decoding with @file{ffmpeg} you can use the
ffmpeg -benchmark -i INPUT -f null out.null
@end example
Note that the above command does not read or write the @file{out.null}
file, but specifying the output file is required by the @file{ffmpeg}
Alternatively you can write the command as:
ffmpeg -benchmark -i INPUT -f null -
@end example
@c man end MUXERS @c man end MUXERS
