I've been using nuvexport to transcode some of my HD programs.
I have to use the -mencoder option to nuvexport, otherwise
mythtranscode seems to leak memory like a seive. Unfortunately,
nuvexport does not have an easy way to export to dvd when using
the -mencoder flag.
I've gotten the following mencoder commandline to convert to pure
mpeg2, but I'm at a loss how to make it scale its output to a DVD
mencoder -idx /data/1005_20051024070000_20051024080000.nuv -zoom
720x480 -of mpeg -mpegopts format=dvd -srate 48000 -ofps 30000/1001
-ovc lavc -oac lavc -lavcopts vcodec=mpeg2video:
vrc_buf_size=1835: keyint=18: vrc_maxrate=9800: vbitrate=4900:
acodec=ac3:abitrate=192 -o /data/mythvideo/Bears.mpg
I have also tried moving the zoom 740x480 around, and using
-vf scale=720:480. This gets ignored, and the resulting mpg always
seems to be 1920x1080.
Thanks for any help,
