I *did*. The most recent occurrence of 'encode2' in the MPlayer 'svn log'
output, prior to the one from the commit that fixed this, is from a commit by
Diego in 2009.


Also, I'm now getting a different error when trying to encode in to ffv1 with
vpass=3, which at a glance looks like it might be related:

====
videocodec: libavcodec (720x480 fourcc=31564646 [FFV1])
[VE_LAVC] High quality encoding selected (non-realtime)!
Assertion s->version>=2 failed at libavcodec/ffv1.c:994
Aborted
====

Do I need to report that to one of the two libav* projects (and isn't *that* a
headache), or is it likely to be due to a problem on the MPlayer side of things?

side of it.

Every time you let somebody set a limit they start moving it.
