How to use a Sigma Designs Hollywood Plus and/or a Creative DXR3 by David Holm
|
|
==============================================================================
|
|
|
|
Thanks goes out to Daniel Bell for the donation of a brand new 20GB IBM
|
|
harddisk.
|
|
|
|
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 <mplayerdir>/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:<devicenum> For video output :<devicenum> is not needed unless
|
|
you have more than one em8300 device in your computer
|
|
-vo dxr3:noprebuf Turn of prebuffering. This is only needed if you are
|
|
having sync issues with normal playback, this will
|
|
make playback appear less smooth and will not use all
|
|
available cpu power when playing non-mpeg content.
|
|
Note: With prebuffering A-V: should be negative, if
|
|
it's nonnegative your computer is too slow to
|
|
properly play the video and you should disble
|
|
prebuffering if you have sync issues.
|
|
Without prebuffering this value should stay
|
|
close to 0 at all times.
|
|
Note2: Some very fast computers seems to have issues
|
|
with prebuffering. Blame Sigma for that ;).
|
|
You can safely use :noprebuf since your machines
|
|
are fast enough to give you smooth playback anyway.
|
|
-ao oss:<devicefile> For audio output
|
|
-ac hwac3 For digital audio output instead of
|
|
analog
|
|
-vc mpegpes For mpeg playback
|
|
-scalefactor <float> Set the scale factor for libavcodec.
|
|
1.0 = Normal res
|
|
2.0 = Double res
|
|
0.5 = Half res
|
|
You get the drift, anyway, this is useful for those of you
|
|
on slower machines who would want to watch that brand new
|
|
divx file, just set this to a value as close to 1.0 as
|
|
possible where you still get decent playback speed.
|
|
-aop list=resample:fout=48000 If samplerate is below 44100Hz
|
|
This does not work with digital audio output
|
|
(-ac hwac3)
|
|
<devicenum> 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
|
|
<devicefile> Normally /dev/em8300_ma or
|
|
/dev/em8300_ma-<devicenum>
|
|
(-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.
