New can't find ffmpeg error

I've been running serviio on Freebsd for a couple of years, building it and its dependencies out of the FreeBSD ports collection. I'm currently running FreeBSD 10.0-STABLE. When I updated the system recently and built the latest serviio I started having problems. Specifically, it's the old "can't find ffmpeg" issue - the log says

2014-05-14 16:59:49,202 ERROR [ProcessExecutor] Fatal error in process starting: Cannot run program "/usr/local/bin/ffmpeg": error=2, No such file or directory

Of course ffmpeg is installed at /usr/local/bin:

% which ffmpeg
/usr/local/bin/ffmpeg
% ffmpeg -version
ffmpeg version 2.1.1

and I've had a "-D" in my startup to set the ffmpeg location, as described elsewhere on this site, for quite some time.

Why else would serviio choke and not be able to find the ffmpeg executable?

[zip]

access rights?

Unfortunately it doesn't look like it:

% ls -l /usr/local/bin/ffmpeg
-rwxr-xr-x 1 root wheel 179760 Apr 28 22:13 /usr/local/bin/ffmpeg*

This turned out to be an OpenJDK7 issue. Updating my system today and the ports notes mention that there was an issue with the last release of OpenJDK7, deinstall and install the new version to clean it up properly. After that (along with wiping Serviio data again) Serviio is back to indexing properly.
