[mythtv-users] Upgrade to MythTV-0.24.2 broke nuvexport (again) on Gentoo

[Dale Pontius]

Is there a solution for getting xvid out of mythtv other than nuvexport?
That lacking, now that mythtv-0.25 is officially released, when will the 
Gentoo version go stable?  (In the overlay, I know nobody here controls 
what portage does.)

The other night I tried running nuvexport again, for the first time 
since before Christmas.  It's broken, apparently by the upgrade to 
mythtv-0.24.2.  I run Gentoo, which withdrew nuvexport years back, when 
qt3 went away and mythtv-0.22 went stable.

I've kept an old version of nuvexport running in a private overlay, by 
patching a few pieces of MythTV.  I also have a local copy of 
ffmpeg-0.5.whatever that works with it, and have a wrapper that prepends 
PATH and LD_LIBRARY_PATH.  As I said, it worked shortly before 
Christmas, when I was last transcoding.

I've recorded some stuff for a friend, and I've given him xvids before.  
Perhaps he can use other formats, but without experimentation I only 
know that he can use xvid avis and classic DVD.

I see that nuvexport is in the Gentoo overlay, but only against 
mythtv-0.25, so obviously picking that up would be the best option, now 
that mythtv-0.25 is released, but only once the Gentoo release is 
brought up to date.  Hence my questions.

I've run "nuvexport --debug" and see 3 main differences from last time I 
successfully fixed this kind of problem.  Some of these problems have 
recurred.  I have notes from having done this before, but that was back 
in 2010, and I'm now discovering that those notes are incomplete.  
Furthermore, I had help back then, and don't really remember the debug 
process that well.
1 - Last time, I had to remove the "-threads 2" argument from the ffmpeg 
call, and that argument is back again, but I don't remember where to 
remove it.
2 - Last time I had to remove the "-r 16" argument from the "yuvdenoise" 
step.  It too is back again, but again not my memory of fixing it.
3 - This one is new...  When specifying the video codec to ffmpeg it 
used to be "-vcodec libxvid" and is now "-vcodec xvid".   I'm guessing 
that somewhere it's looking to the new ffmpeg options instead of the 
ffmpeg options of my saved-aside version.

Can anyone help with alternatives?
