I just happened to run into this too while encoding for Blu-ray and
for web. It does fail, but only when including audio as you mentioned.
My Blu-ray script runs fine because it only generates a video file,
but my web script fails because it includes a separate audio file on
the ffmpeg command line. I get the following error:

[NULL @ 0x101801800] [Eval @ 0x7fff5fbfe140] Undefined constant or
missing '(' in 'baseline'
[NULL @ 0x101801800] Unable to parse option value "baseline"
[NULL @ 0x101801800] Error setting option profile to value baseline.

This is on Mac OS X/darwin x86_64.
