The option "-lavfopts format=3gp" should supposedly work, but regrettably I
have not been able to encode anything playable on my P990.
But 3GP should be some kind of subset of mpeg4, and I can make playable files
using "-lavfopts format=mpeg4" instead.
I use a script plus an option file as follows:
# This is avi2mp4.sh
if [ $# -eq 0 ]
echo Usage: $0 output [mencoder-options...]
for V in 1:turbo 2:vb_strategy=0
mencoder -include ~/.mplayer/mencoder.mp4 -lavcopts vpass=$V -o "$@"
# This is mencoder.mp4
# Write your default config options here!
The file made in this way play OK, but the P990 spends a lot of time opening
them before playback starts. There's a lot of discussions about this on the
symbian fora at http://my-symbian.com/forum/, but no real solutions so far
other than recommendations for specific (windows only) softwares.
I'm guessing the P990 expects but doesn't find some kind of index and thus has
to scan the entire movie before playback. This is just idle speculation...
