<P>And we have idegs. And our idegcounter overflowed 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 Red Hat or SuSE, and without RTFM'ing they
|
|
send messages saying 'it doesn't work! help me! please! i'm new to Linux!
|
|
help! oh! help me!'. We can't stop them, but at least we try to force them to
|
|
RTFM and to read the 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 the one side are you, clever guys, saying we are
|
|
very bad because we don't like buggy gcc 2.96, and on the other side 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 the 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 could earn lots of money with it and buy a
|
|
big house, etc etc. Do you really want it? It seems.</P>

This parameter can be computed easily:
|

<OL>
|
|
<LI>Which movies do you plan to watch?
|
|
<UL>
|
|
<LI><B>MPEG1:</B> 320x200@32=256000<BR>
|
|
You need only 256*25fps=6.4MB/sec of bandwidth (This format can be played
|
|
in real-time on any PC since the times of Pentium-100 + S3Virge).</LI>
|
|
<LI><B>MPEG4:</B> 640x480@32=1228800<BR>
|
|
You need a video bandwidth of 1.2*25fps=30MB/sec. To watch such a movie
|
|
in real-time you need a PC equivalent to a Celeron-450 and a DIMM based
|
|
video card.</LI>
|
|
<LI><B>MPEG2 (aka DVD or SDTV):</B> 1024x768@32=3145728<BR>
|
|
You need a video bandwidth of 3*30fps=90MB/sec. In extreme cases (if your
|
|
video card supports IDCT decoding) the hardware requirements are the same
|
|
as for MPEG4.</LI>
|
|
<LI><B>HDTV (High Definition TeleVision):</B> 2000x2000@32=16000000<BR>
|
|
You need a video bandwidth of 16*30fps=480MB/sec. You also need at least
|
|
32MB of video memory to watch this stream: 16MB for the RGB area and 16MB
|
|
for the YUV area.</LI>
|
|
</UL>
|
|
</LI>
|
|
<LI>The bandwidth of PCI slots is: 33MHz*32Bit=133MB/sec. PCI2.1 has
|
|
66MHz*32Bit=266MB/sec which is more than enough for playing any movie (except
|
|
HDTV streams which really require an AGP bus).</LI>
|
|
<LI>What memory type should be installed on the video card:
|
|
<UL>
|
|
<LI><B>SIMM</B> - Avoid that.</LI>
|
|
<LI><B>DIMM</B> - Good if your video card has 128-bit memory access.</LI>
|
|
<LI><B>DDR</B> - Is fast enough for all types.</LI>
|
|
</UL>
|
|
</LI>
|
|
</OL>
|
|
Note: DGA comparison shows that there is no visible difference between video
|
|
cards which have the same type of video memory installed.<BR>
|
|
<B>Conclusion:</B> If you have enough CPU power (Celeron-450 or K6-2-500) it
|
|
should be enough to buy any video card which has at least 8MB of DIMM or DDR
|
|
memory.

<P>It's a very rough overview of video cards. We should pay attention to video
|
|
card models. If for example Matrox G400 drivers support TV-out then G450 and
|
|
G550 do not necessarily have this feature.<BR>
|
|
Another example: Adaptive deinterlacing exists only for the Rage128 chip and
|
|
isn't present on Mach64+ ones. The same goes for 3D features. They are different
|
|
from Mach64 to the Radeon 8500 with TRUFORM technology.</P>

MATERIAL YOU BUY A CARD WHICH IS UNSATISFACTORY FOR YOU!!! THIS IS ONLY OUR

POINT OF VIEW.</B></P>

the S3 Virge too slow for them?<BR>
