Sure...
In this script, I just copy the video and downgrade the sound to mp2.
TARGET="input.ts"
OUTPUT="output.mpg"
mencoder $TARGET -of mpeg \
-oac lavc -lavcopts acodec=mp2:abitrate=384 \
-ovc copy \
-o $OUTPUT
For what seems a more error tolerant file on the MVP, I use
OPTIONS="vbitrate=2500:keyint=25:aspect=4/3:mbd=2:vrc_buf_size=917:vrc_maxrate=2600"
mencoder $TARGET -of mpeg \
-oac lavc \
-ovc lavc -lavcopts acodec=mp2:abitrate=384:vcodec=mpeg2video:$OPTIONS \
-ofps 30000/1001 -o $OUTPUT
I copied a script from my other machine that does mpeg-ps to mpeg4 files, so the
options here may or may not be needed...this was just a quick and
dirty test, but
it seems to work just fine on the MVP. Mencoder coplained about mpeg2 not
doing 29.97 as a frame rate, but the -ofps 30000/1001 made that error go away.
Hope this helps.
