Comment (by barhom):

 I have found the regression.
 It was introduced by the following commit:

 https://github.com/FFmpeg/FFmpeg/commit/4bec36f98c5150b09d45740f3e1c80526e85b676

 Removing the lines

 {{{
     if (pes->stream_type == 4)
          st->request_probe = 50;
 }}}

 from master fixes the problem I have with slow-starting transcodes. I
 suggest that if ffmpeg wants an extra probe for stream_type == 4 then it
 should make it optional somehow.
