Damages the contents of packets without damaging the container. Can be
used for fuzzing or testing error resilience/concealment.
+Parameters:
+A numeral string, whose value is related to how often output bytes will
+be modified. Therefore, values below or equal to 0 are forbidden, and
+the lower the more frequent bytes will be modified, with 1 meaning
+every byte is modified.
+
@example
-ffmpeg -i INPUT -c copy -bsf noise output.mkv
+ffmpeg -i INPUT -c copy -bsf noise[=1] output.mkv
@end example
+applies the modification to every byte.
