<P>But we has idegs (the word 'ideg' is described further in the FAQ). And our
idegcounters overflow again and again.</P>
<P>Unfortunately MPlayer is out of our control. It's used by lamers, Linux users
who can't even use windows, and never tried to compile a kernel. They installed
(with default options) Mandrake or RedHat or Suse, and without RTFM'ing they
send messages saying 'it doesn't work! help me! please! i'm new to the linux!
help! oh! help me!'. We can't stop them, but at least we try to force them RTFM
and to read messages of ./configure and mplayer.</P>
<P>And you clever guys come and flame us with gcc 2.96 and binary packages.
Instead of helping users or making patches to help solve problems.</P>
<P>Half of our spare/free time is spent by answering silly mails here and
making newer tricks and checks to configure to avoid such mails.</P>
<P>And there is a balance. On one hand are you, clever guys, saying we are very
bad because we don't like buggy gcc 2.96, and at the other hand there are the
'new to linux' guys who are showing us gcc 2.96 is buggy.</P>
<P>Conclusion: we can't be good. Half of people always will say we are bad.</P>
<P>Maybe we should close the project, make it closed source, commercial, and
provide install support for it. then we could leave current work, so
development could go faster, and we earn lots of money with it and buy a big
house, etc etc. Do you really want it? It seems.</P>

It does, but you have to explicitly specify software scaling (it's SLOW!) with
the <CODE>-zoom</CODE> option. You better use XF86VidMode support:
you must specify the -vm and the -fs switch, and you're done.
Make sure you have the right Modelines in your XF86Config file, and
try if the DGA driver (and SDL's DGA driver, see RTFM) works for you.
It's much faster. If SDL's DGA works too, use that, it'll be EVEN faster!

Speed:
<br>This
parameter can be computed very easy:
<br><b>a)</b>
which movies do you plan to watch:
<br><b>-
MPEG1:</b> 320x200@32=256000
<br>so
you need only 256*25fps=6.4Mb/sec bandwidth (This format can be played
in real-time on any PC since P-100 + S3Virge)
<br><b>-
MPEG4:</b> 640x480@32=1228800
<br>you
need videobandwidth 1.2*25fps=30Mb/sec To watch such movie in real-time
you need enough power PC: (Celeron-450+DIMM based video card)
<br><b>-
MPEG2 (aka DVD or SDTV):</b> 1024x768@32=3145728
<br>you
need videobandwidth 3*30fps=90Mb/sec In extremal cases (if your video card
supports IDCT decoding) this can be played on the same PC as for MPEG4
<br><b>-
HDTV (HighData TeleVision):</b> 2000x2000@32=16000000
<br>i.e.
videobandwidth = 16*30fps=480Mb/sec (This means also that you need at least
32Mb of video memory to watch this stream: 16Mb for RGB area and 16Mb for
YUV area)
<br><b>b)</b>
Bandwidth of PCI slot is: 33Mhz*32bit=132Mb/sec And PCI2.1 has 66MHz*32bit=265Mb/sec
that is far enough for any movie playback (except HDTV streams which really
require AGP bus).
<br><b>c)</b>
What memory type should be installed on video card:
<br><b>SIMM</b>
- avoid that
<br><b>DIMM</b>
- good if your video card has 128-bit memory access.
<br><b>DDR</b>
- is far enough for all types.
<br>Note:
By DGA comparision - there is no any visible difference between video cards
which have installed the same type of video memory.
<br><b>Resume:</b>
If you have enough power CPU (Celeron-450 or K6-2-500) it would be enough
to buy any video card which has at least 8Mb of DIMM or DDR memory.

<p>Well
- it's very rude observing of video card. Indeed we should pay our attention
for models of video card:
<br>For
example if MatroxG400 drivers support TV-out then G450 and G550 has no such
support.
<br>Other
sample: Adaptive deinterlacing exists only since Rage128 chip and isn't
present on Mach64+ ones. Same as 3D features are far different from Mach64
to Radeon2 8500 with trueform possibilities.
