Hello!
I noticed that encoding mpeg2 TS streams to divx with
mencoder -ni -cache 4096 in.vdr -o out.avi \
-ovc lavc -lavcopts vcodec=mpeg4:vqmin=2:mbd=0:vpass=1 \
-oac mp3lame -lameopts q=0:vbr=0:aq=0
takes about four times longer than with
mencoder -ni -cache 4096 in.vdr -o out.avi \
-ovc lavc -lavcopts vcodec=mpeg4:vqmin=2:mbd=0:vpass=1 \
-oac copy
This would mean that audio encoding takes about three times longer than
video encoding. I alway thought that encoding video is much more
CPU-intensive than encoding audio. How comes that audio encoding
is such a CPU-hog? How can I speed this up?
