FreeBSD 10 - mplayer issue

Possibly orthogonal to your question, but is it an option to consider
another product? MPV is an mplayer2 fork (which was [until development
stalled] a fork of/drop-in replacement for mplayer), and seems to be pretty
well supported on FreeBSD. It's pretty featureful (10-bit video and
whatnot), and has a relatively fast development cycle (particularly
compared to the crawl mplayer operates at), though it's at the expense of
losing mencoder. Some of the command-line flags have been changed as well,
which may require tweaking in your work-related tools (if they can be

Barring that, I'd recompile with debug flags and run in gdb/lldb. Wait till
it locks, C-c, 'bt'. It's almost certainly some manner of deadlock if
you're stuck in urdlck, which may be a bug in mplayer's threading or in
pthreads. Either way, it'd help to know where the problem lock is.
