Comment (by xzerth):

 You can reproduce the problem with my command.
 Also if you want to see "good" PCR corresponding muxrate, you can just
 decrease number of copy streams:
 {{{
 ~# bin/ffmpeg -i pipe:0 -codec:0 copy -map 0:0 -codec:1 copy -map 0:1
 -max_delay 3000000 -muxrate 13000k -f mpegts pipe:1 < input.ts > out.ts
 }}}

 I'm using pipe because it's convenient with my encoding environment.
 Thanks for notice about build flags - it's remain from another build
