Videocards with hardware acceleration:
|
||
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||
|
|
|
||
|
|
* read DOCS/MTRR too!
|
||
|
|
|
||
|
|
"Hardware acceleration" usually means hardware YUV conversion, scaling,
|
||
|
|
bilinear filtering. Under Linux and XFree86, this is done by the XVideo
|
||
|
|
extension, this is what the option '-vo xv' uses.
|
||
|
|
In order to make this work, be sure to check the following:
|
||
|
|
1. your card actually supports harware acceleration
|
||
|
|
2. you use XFree86 4.0.2 or newer (former versions don't have XVideo)
|
||
|
|
3. X loads the XVideo extension, it's something like this:
|
||
|
|
(II) Loading extension XVideo
|
||
|
|
in /var/log/XFree86.0.log
|
||
|
|
NOTE : this loads only the XFree86 support. In a good install, this is
|
||
|
|
always loaded, and doesn't mean that the _card's_ XVideo support is
|
||
|
|
loaded!
|
||
|
|
4. The XVideo extensions can use your card. Try 'xvinfo' which is the part of
|
||
|
|
the XFree86 distribution. It should display a long text, similar to this:
|
||
|
|
|
||
|
|
X-Video Extension version 2.2
|
||
|
|
screen #0
|
||
|
|
Adaptor #0: "Savage Streams Engine"
|
||
|
|
number of ports: 1
|
||
|
|
port base: 43
|
||
|
|
operations supported: PutImage
|
||
|
|
supported visuals:
|
||
|
|
depth 16, visualID 0x22
|
||
|
|
depth 16, visualID 0x23
|
||
|
|
number of attributes: 5
|
||
|
|
(...etc...)
|
||
|
|
5. Be sure MPlayer is compiled with the "xv" target. "./configure" should say:
|
||
|
|
Checking for Xv ... yes
|
||
|
|
6. If all is fine, try the option '-vo xv' . It should work.
|
||
|
|
(if it doesn't, send us a bugreport. See the README on how to do this.)
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
There are additional drivers for the Matrox cards, which are usually
|
||
|
|
better than XVideo, consume much less CPU, and some doesn't even need X.
|
||
|
|
(Arpi please complete this section somewhat :) I'll correct your english:)
|
||

|
If your card lacks hardware acceleration, you can still boost your fps by
|
||
|
|
using the DGA driver.
|
||
|
|
1. Make sure X loads the DGA extension:
|
||
|
|
(II) Loading extension XFree86-DGA
|
||
|
|
2. MPlayer's DGA driver is autodetected on ./configure, or you can force it
|
||
|
|
with --enable-dga.
|
||
|
|
3. Be sure to use 24/32bpp mode, since there is no converter right now.. :(
|
||
|
|
4. Install MPlayer SUID root.
|
||
|
|
(see the FAQ on how to do this, and... heed the warning!)
|
||
|
|
5. Use '-vo dga' option, and there you go! (hope so:)
