How to use a Sigma Designs Hollywood Plus and/or a Creative DXR3 by David Holm ============================================================================== 1. Requirements * First of all you will need the DXR3/H+ drivers properly installed. Version 0.10.0 or later. You can find it at http://dxr3.sourceforge.net/ * Run /configure and make sure that DXR3/H+ support = yes if you want to play files other than mpeg libmp1e should be = yes as well From here on compilation (of at least my code ;) should go without any problems. 2. Usage -vo dxr3: For video output -ao oss: For audio output -ac hwac3 For digital audio output instead of analog -vc mpegpes For mpeg playback -aop list=resample:fout=48000 If samplerate is below 44100Hz Number of device to use for playback (if you have more than one card.). This can usually be left out (-vo dxr3). Mandrake 8.1 uses devfs by default. If you are running mandrake 8.1 please use -vo dxr3:0 Normally /dev/em8300_ma or /dev/em8300_ma- (-ao dxr3:/dev/em8300_ma). If left out the default oss device will be used (normally soundcard). MPEG-1, MPEG-2, VCD and DVD Notes There are some important notes to take into account here for optimum playback. MPlayer currently does not autodetect that the dxr3 can playback mpegs. So for mpeg files, dvd's and vcd's you have to add -vc mpegpes to tell mplayer that you are using a hardware accelerator. Otherwise mplayer will decode the movie in software, which is much slower. Note that you cannot use -vc mpegpes with movies that aren't mpeg 1 or 2 or you will get an error message saying "Can't find codec for video format...". * If you run mplayer as root, or set userid root it will use your pc's internal realtime clockgenerator for syncing. (If your kernel supports it (It's located in character devices and called "Enhanced realtime clock support")). Some people report that this has improved playback (which it should), but others have had problems with it. You will have to experiment yourself with this to find your optimum setup. 3.
