ffmpeg configure task fails on first run

[mark-dce]

On a vanilla centos server, I'm getting a failure on the "configure ffmpeg task", but if you run the script again starting at that same step, it runs without error and the playbook finishes successfully.

TASK: [ffmpeg | configure ffmpeg] ********************************************* 
failed: [hydra-head] => {"changed": true, "cmd": "cd /opt/install/ffmpeg_sources/ffmpeg && ./configure --extra-libs=\"-ldl\" --enable-gpl --enable-nonfree --enable-libfdk_aac --enable-libmp3lame --enable-libopus --enable-libvorbis --enable-libvpx --enable-libx264", "delta": "0:00:04.605410", "end": "2015-09-09 03:00:32.271602", "rc": 1, "start": "2015-09-09 03:00:27.666192", "warnings": []}
stdout: ERROR: opus not found using pkg-config

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

FATAL: all hosts have already failed -- aborting

PLAY RECAP ******************************************************************** 
           to retry, use: --limit @/Users/mark/vanilla.retry

hydra-head                 : ok=144  changed=108  unreachable=0    failed=1   

BUT THEN, this works fine

MARKs-MB:sufia-centos mark$ ansible-playbook vanilla.yml --start-at-task="configure ffmpeg"

PLAY [provision vanilla centos 7 host via ssh] ******************************** 

GATHERING FACTS *************************************************************** 
ok: [hydra-head]

TASK: [ffmpeg | configure ffmpeg] ********************************************* 
changed: [hydra-head]

TASK: [ffmpeg | make ffmpeg] ************************************************** 
... ETC.
