 Not sure if this is labelled a bug or more a new feature/feature change
 but it was mentioned that it might should be raised with ffmpeg.

 The issue is that when I pipe video in node.js to a ffplay child-process
 the log output is blocking. This means that after a while playing the
 video will halt because the output buffer from stdout fills up with
 progress information. It's easy to work around, but it was claimed that it
 seems unnescessary to block on log output. I myself have no strong
 opinions on the issue, but I thought I should bring it up.
