|

|
|
|
<BLOCKQUOTE>
|
|
|
|
|
<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 will always 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>

It does <B>not</B> work with any previous version. So if you choose to use

now?</DT>
|

<DD>A: Where did you install the SDL library? If you installed in /usr/local
|
|
|
|
|
(the default) then edit the top level config.mak and add
|
|
|
|
|
"-L/usr/local/lib" after "X_LIBS=". Now type make. You're done!</DD>

<A HREF="documentation.html#debian">Debian packaging</A> section.

|
<DD>A: ... but you don't have the X development package installed. Or not
|
|
|
|
|
correctly. It's called XFree86-devel* under Red Hat, and xlibs-dev under
|
|
|
|
|
Debian. Also check if the <CODE>/usr/X11</CODE> and <CODE>/usr/include/X11</CODE>
|
|
|
|
|
symlinks exist (this can be a problem on Mandrake systems). They can be
|
|
|
|
|
created with these commands:<BR>
|
|
|

|
<CODE>$ ln -sf /usr/X11R6 /usr/X11</CODE><BR>

(mainly to avoid kernel hackers debugging closed source drivers).

<DT>Q: Can I run multiple instances of MPlayer?</DT>
|
2002-10-19 22:06:46 +00:00
|
|
|
<DD>A: Yes. Some video out drivers like xv, dga or (x)mga are exclusive, some
|
|
|
|
|
are exclusive in combination with certain graphics boards and drivers. You
|
|
|
|
|
will not be able to run more than one instance of MPlayer with one of those
|
|
|
|
|
video out drivers. To a lesser degree this also applies to audio drivers.
|
|
|
|
|
Not all allow playback of multiple streams on the same device.</DD>

|
2002-08-15 12:42:52 +00:00
|
|
|
<DD>A: It does, but you have to explicitly specify software scaling (very
|
|
|
|
|
slow) with the <CODE>-zoom</CODE> option. You better use XF86VidMode
|
2002-08-11 22:24:26 +00:00
|
|
|
support: You must specify the <CODE>-vm</CODE> and the <CODE>-fs</CODE>
|
2003-01-28 17:11:57 +00:00
|
|
|
option, and you're done. Make sure you have the right modelines in your
|
2002-08-11 22:24:26 +00:00
|
|
|
XF86Config file, and try to make the <A HREF="video.html#dga">DGA driver</A>

and <A HREF="video.html#sdl">SDL's DGA driver</A> work for you.
|
2002-08-15 12:42:52 +00:00

<DT>Q: Why is video_out cpu usage zero (0%) for some files?</DT>
|
|
|
|
|
<DD>A1: It's not zero, but it's called from the codec and thus cannot be
|
|
|
|
|
measured separately. You should try to play the file using
|
|
|
|
|
<CODE>-vo null</CODE> and then <CODE>-vo ...</CODE> and check the
|
|
|
|
|
difference to see the video_out speed.</DD>
|
|
|
|
|
<DD>A2: You are using Direct Rendering,
|
|
|
|
|
where the codec renders to the video memory itself. In this case, the
|
|
|
|
|
decoding percentage contains the display percentage, too.</DD>

The only common thing between these players is the Win32 DLL loader.

The codecs (DLL) set, synchronization, demultiplexing etc is totally

security patches (for example Solar Designer's OpenWall patch) which

Because l3codeca.acm is a non-relocatable DLL, it must be loaded to

<DD>A: You don't need to. Use <B>libmpdvdkit2</B>, which is present in the

MPlayer source, and used by default. You can get the mentioned packages

and try enabling DMA for the DVD drive with the hdparm tool (described in

source ASF parsers, open source ASF encoders, etc) and you'll know why. We

file-specific options in it and put it in <CODE>~/.mplayer</CODE> or in

<DT>Q: How can I join two video files?</DT>
|
|
|
|
|
<DD>A: This has been discussed to no end on mplayer-users. Go search the
|
|
|
|
|
<A HREF="http://mplayerhq.hu/cgi-bin/htsearch?restrict=/mplayer-users/">archives</A>
|
|
|
|
|
for a complete answer. This is a complicated topic and your mileage may
|
|
|
|
|
vary a lot depending on the kind of files you want to merge. MPEGs can be
|
|
|
|
|
concatenated into a single file with luck. For AVIs there are two tools,
|
|
|
|
|
<A HREF="http://fixounet.free.fr/avidemux/">avidemux</A>
|
|
|
|
|
and avimerge (part of the

|
|
|
|
<A HREF="http://www.theorie.physik.uni-goettingen.de/~ostreich/transcode/">transcode</A>
|
|
|
|
|
tool set), available that might do the job. You can also try MEncoder if
|
|
|
|
|
you have two files sharing the same dimensions and codec. Try<BR>
|
|
|
|
|
<CODE>cat file1 file2 > file3</CODE><BR>

<CODE>mencoder -ovc copy -oac copy -o out.avi -forceidx file3.avi</CODE></DD>

<DT>Q: Why is the recommended bitrate printed by MEncoder negative?</DT>
|
|
|
|
|
<DD>A: Because the bitrate you encoded the audio with is too large to fit the
|
|
|
|
|
movie on any CD. Check if you have libmp3lame installed properly.</DD>
