[mythtv-users] nuvexport slash ffmpeg problem?

[Grant Swenson]

I'm having trouble with the latest nuvexport tool. Passing "debug" shows: 

system call:
mkdir -m 0755 /tmp/fifodir_10794/

forking:
/bin/nice -n19 mythtranscode --showprogress -p autodetect -c 1013 -s
2005-03-23-19-29-00 -f "/tmp/fifodir_10794/" --honorcutlist 2>&1

forking:
/bin/nice -n19 ffmpeg -hq -y -f s16le -ar 32000 -ac 2 -i
/tmp/fifodir_10794/audout -f rawvideo -s 480x480 -r 29.97 -i
/tmp/fifodir_10794/vidout -deinterlace -croptop 10 -cropbottom 10
-cropleft 10 -cropright 10  -vcodec mpeg4 -b 960 -minrate 32 -maxrate
1920 -bt 32 -lumi_mask 0.05 -dark_mask 0.02 -scplx_mask 0.7 -acodec
mp3 -ab 128 -s 320x240 -f avi "./Alan Alda in Scientific American
Frontiers - Hidden Motives.2.avi" 2>&1

and when I try these by hand, I get:

Error while opening codec for output stream #0.0 - maybe incorrect

Any ideas here? Searching for this error "a vbv buffer size is needed"
doesn't help.

Thanks!
