Introduction

The mplayer build does not support interlaced playback (it will fail rather than just look bad)

Details

Before beginning, ensure that you have a recent mplayer build (only SVN is supported, but recent snapshots should work as well)

1) Download the code from svn: svn checkout http://coreavc-for-linux.googlecode.com/svn/trunk/ coreavc-for-linux cd coreavc-for-linux

2) Install dshowserver forrlowing these instructions: DshowserverInstall

3) Install patch into mplayer: cd <path to mplayer source code> patch -p0 < <path to coreavc-for-linux>/mplayer/dshowserver.patch make make install

4) Update codecs.conf * If you don't have ~/.mplayer/codecs.conf mkdir ~/.mplayer cp <path to mplayer source>/etc/codecs.conf ~/.mplayer/ * Add the following to the end of ~/.mplayer/codecs.conf videocodec coreserve info "CoreAVC DShow H264 decoder x.x for x86 - http://corecodec.org/" status working format 0x10000005 fourcc H264,h264 H264 fourcc X264,x264 fourcc avc1,AVC1 AVC1 fourcc davc,DAVC fourcc VSSH driver dshowserver dll "CoreAVCDecoder.ax" guid 0x09571a4b, 0xf1fe, 0x4c60, 0x97, 0x60, 0xde, 0x6d, 0x31, 0x0c, 0x7c, 0x31 out YV12,IYUV,I420,YUY2

Playing tips

to use coreavc, you may need to add '-vc coreserve' (assuming you use the above codecs.conf options)

you may also need to use '-demuxer lavf' for some formats (TS streams for example)

with current mplayer you may also need -no-correct-pts to prevent jerky playback.
