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 0.12.0 or later. You can find it at
|
|
http://dxr3.sourceforge.net/
|
|
(you only need to run "make install devices" in em8300-x.y.z/modules
|
|
not in the root dir)
|
|
|
|
* Run <mplayerdir>/configure and make sure that DXR3/H+ support = yes
|
|
if you want to play files other than mpeg I highly recommend you install
|
|
libavcodec as well (Read DOCS/codecs.html for more info).
|
|
|
|
From here on compilation (of at least my code ;) should go without any
|
|
problems.
|
|
|
|
|
|
|
|
2. Usage
|
|
-vo dxr3:<noprebuf>:<codec>:<device>Where noprebuf specifies to turn off
|
|
prebuffering. This is done automatically
|
|
on athlons. If playback is out of sync
|
|
try disabling prebuffering. If noprebuf
|
|
is left out prebuffering is enabled
|
|
(except on athlons).
|
|
|
|
<codec> = fame/avcodec, avcodec produces
|
|
better quality output, but fame is
|
|
faster for those of you with slow
|
|
machines. The default is to use
|
|
libavcodec. Note that you need
|
|
libavcodec properly installed (read
|
|
DOCS/codecs.html)
|
|
|
|
<device> = device number to use in case
|
|
you have more than one em8300 card
|
|
|
|
Any of these options may be left out,
|
|
but they must be specified in this order
|
|
i.e. dxr3:fame works, dxr3:1 works but
|
|
dxr3:1:avcodec will not.
|
|
These new features were added by XorA,
|
|
he usually hangs out in #dxr3 on
|
|
irc.openprojects.net, let him know
|
|
you like it...
|
|
-ao oss:/dev/em8300_ma-X For audio output, where X is the device
|
|
number (0 if one card)
|
|
-ac hwac3 For digital audio output instead of
|
|
analog
|
|
-vc mpegpes Force hardware acceleration, only works
|
|
with mpeg1/2
|
|
-aop list=resample:fout=xxxxx If samplerate is below 44100Hz, select
|
|
either 44100 or 48000 depending on
|
|
which which one matches closest. I.e.
|
|
if the movie uses 22050 use 44100 as
|
|
44100 / 2 = 22050, if it's 24000 use
|
|
48000 as 48000 / 2 = 24000 and so on.
|
|
This does not work with digital audio
|
|
output (-ac hwac3)
|
|
|
|
MPEG-1, MPEG-2, VCD and DVD Notes
|
|
MPEG 1/2 content should now automatically be detected by mplayer and it will
|
|
use the hardware acceleration of the DXR3 to play it. If not, you can force
|
|
it to hardware acceleration with -vc mpegpes. Also, if you plan to use any
|
|
postprocessing filters you must use -vc mpeg12.
