 Summary of the bug:
 There are a number of documented (http://ffmpeg.org/ffmpeg-
 all.html#ebur128-1) ebur128 filter flags that don't appear to work, e.g.
 "scale," target," and "guage" all result in messages like:

 {{{
 [Parsed_ebur128_0 @ 0x7fffd66c6f20] Option 'target' not found
 [AVFilterGraph @ 0x7fffd66f2120] Error initializing filter 'ebur128' with
 args 'video=1:target=-24LUFS'
 }}}


 How to reproduce:
 {{{
 % ffmpeg -i $SOURCE_FILE -filter_complex "ebur128=video=1:target=-24LUFS"
 -vcodec libx264 -acodec aac loudness.ts
 3.4.6-0ubuntu0.18.04.1
 }}}

 Attaching a log of a run that failed like this.
