[vlc-devel] Please help: OSS audio output and main audio output error in VLC v0.6 on XScale platform

[Hor Keng Seng]

Hi VLC developers,

I'm currently cross-compiling VLC v0.6 in a XScale environment, the 
compiler was used from Montavista Linux 3.1 Pro. This is the 
configuration that i'd set before compile the VLC player:

./configure --prefix=/opt/hardhat/devkit/arm/xscale_be --host=xscale 
--target=xscale CC=/opt/hardhat/devkit/arm/xscale_be/bin/xscale_be-gcc 
--disable-mad --disable-screen --disable-ffmpeg --enable-libmpeg2 
--disable-dvbsub --disable-gnomevfs --disable-sdl --disable-dvd 
--disable-gtk --disable-x11 --disable-freetype --disable-skins2 
--disable-wxwindows --disable-plugins --enable-shared-pp --enable-pp 
--enable-shared --disable-gtk --disable-x11 --disable-gnome --disable-qt 
--disable-kde --disable-qte --disable-xosd --disable-dummy -disable-opie 
--with-libmpeg2-tree=/root/mmp/videolan_xscale/libraries/mpeg2dec-0.4.1-cvs/

But, when I trying to play mpeg2 media file, some error messages show 
that the OSS audio output error and main audio output error, as shown 
below. What have I done wrong for the configuration or others part 
problem(s), please share your valuable comment on this issue, very thanks!
