[MPlayer-users] MPlayer memory leak with lavc output

I'm seeing a memory leak with mencoder when capturing data from a USB
video camera and outputting to a file using -ovc lavc:
./mencoder tv:// -tv
driver=v4l2:noaudio:device=/dev/video0:width=640:height=480:fps=60 -o
/tmp/outtest.avi -ovc lavc
I've tested with MPlayer-1.3.0 and with last night's build
(2017-05-24). In both versions I get a memory leak of over
100K/minute.
mplayer playing from the same camera:
./mplayer tv:// -tv
driver=v4l2:noaudio:device=/dev/video0:width=640:height=480:fps=60
Does not have a memory leak.
The video camera is an e-con See3CAM, but we see the same problem with
an older Philips camera as well.
I can provide mencoder output for a short run if that's helpful (I
couldn't attach logs due to message size limits).
Any clues as to ways around this, or how to go about debugging further
would be much appreciated. We're trying to update from a MUCH older
version of MPlayer to something newer (to support new cameras), and
this leak kills us after a day or two of running.
CentOS 6.6

I'm running on a system slightly different than the one I build on.
The target system is the one where I'm RUNNING, the build system is
where I built the latest version of MPlayer.
This is libc from the target system.
