[MPlayer-users] How to build mplayer with multi-threaded video decoding

[陳鈞宇]

Hi there,

I followed the instructions below to build mplayer with multi-threaded video decoding but had been always getting one with only single-threaded  video decoding.

What can I do to fix this problem? Thanks in advance!

OS: Debian squeeze 6.0
CPU: Intel Pentium DC E2140
---------------------------
# cd /dev/shm
# apt-get install git subversion libxv-dev libclalsadrv-dev build-essential
# svn co svn://svn.mplayerhq.hu/mplayer/trunk mplayer
# git clone git://git.videolan.org/ffmpeg.git
# mv ffmpeg mplayer
# cd mplayer
# ./configure --disable-inet6 --disable-mencoder --extra-cflags="-mtune=core2"
# make -j 2
# make install
# mplayer -lavdopts threads=2 -vf pp=lb /mnt/Video/HiHD.ts
---------------------------
