Building Mplayer with Unichrome Pro and XviD Support

Instructions according to http://www.openchrome.org/snapshots.html and http://www.mplayerhq.hu/DOCS/HTML/en/index.html

Install OpenChrome Drivers 

tar xfj unichrome-20051109.tar.bz2
cd unichrome-20051109/drm/linux-core
make LINUXDIR=/usr/src/linux DRM_MODULES=via
cp *.ko /lib/modules/`uname -r`/kernel/drivers/char/drm/
depmod -ae
  • Build libxvmc 
cd libxvmc
xmkmf /usr/src/xc
make
make install

If the xmkmk step fails because of missing host.def and date.def, you forgot to "make World" in /usr/src/xc. Do it now and try again.

  • Build Driver 
   cd unichrome
   xmkmf /usr/src/xc
   make
   make install

During make we get:

aaaargh pages and pages of errors :-((((( syntax, not found, etc. etc... maybe we should use a more stable version of xorg? no, tried it with X11-6.8.2, same problem (even had to do the same hack with the date.def and host.def)

enough for tonight... Arnolde 03:22, 31 December 2005 (CET)

Ok let's continue (Arnolde 16:10, 31 December 2005 (CET)): Got a reply back from Ivor suggesting to try his latest code from SVN. After searching for 20 minutes trying to find out what SVN is, I found that it's called Subversion and is supposed to replace CVS someday. Installing is easy enough 

emerge subversion

BUT unfortunately it seems to rely on a lot of stuff (perl, etc.) that I didnt have so it's been emerging for quite a while now and I still can't use it yet *grrrrr*

I just looked at the starting time and the "emerge subversion" has been running for 45 minutes now... I really have to gripe about this, I mean really, all this thing does is download a few files from a server for me, right? I can see that it might need perl, if it's written in that language. But man, why all this crap that takes ages and ages to compile... *rant* *rave*

Yeah, one hour and 10 minutes later, I can finally download the svn version of openchrome... But same things happen, that didnt change anything. (I would have been surprised, anyway).

Ok so then I unpacked the whole X source again into a new test directory, just to make sure it hadnt been messed up somehow, and tried again. This time I got a little further, no missing files this time, but I got the same error this guy had: http://www.openchrome.org/trac/ticket/17

So since he seemed to solve his problem with xorg-7.0 now I am installing that too, according to these instructions: http://gentoo-wiki.com/HOWTO_Modular_Xorg (which will probably take at least the rest of this year to finish installing). Arnolde 19:50, 31 December 2005 (CET)

Ok, now I'm proud owner of xorg-server 7.0... Will it be any use? 

openchrome # autogen.sh
openchrome # make

ouch, it does compile for a while, but still get an error: 

In file included from via_memory.c:34:
/usr/include/xorg/xf86drm.h:39:17: drm.h: No such file or directory

I see such a file exists: /usr/include/drm/drm.h so I add that directory to the XORG_CFLAGS in the openchrome Makefile (the one in the unichrome directory!), but that didnt help, also I see that my edit did not take effect, the additional -I/usr/include/drm does not appear, so that must be done somewhere else...

Still dont know where those includes are defined, but this finally did the trick: 

cp /usr/include/drm/drm.h to the unichrome directory

Ok well supposedly the openchrome drivers are now all compiled. But mplayer still won't compile, still fails to compile: 

libavcodec/libavcodec.a(allcodecs.o)(.text+0x35a): In function `avcodec_register_all':
: undefined reference to `mpeg_xxmc_decoder'
collect2: ld returned 1 exit status
make: *** [mplayer] Error 1
  • added +dri +drm to my /etc/make.conf
  • emerge x11-base/xorg-server x11-drivers/xf86-video-via

OK I'm getting there... found a typo in allcodecs.c - just changed "xxmc" to "xvmc" and it worked! So make install, and I finally have my new xvmc-enabled mplayer. Now to get it to start: 

modprobe via_agp
modprobe agpgart

dmesg shows: 

Linux agpgart interface v0.101 (c) Dave Jones
agpgart: Detected VIA PM800/PN800/PM880/PN880 chipset
agpgart: AGP aperture is 32M @ 0xea000000

then: 

modprobe via
modprobe drm

dmesg shows:

waiting for X server to shut down .FreeFontPath: FPE "/usr/share/fonts/misc" refcount is 2, should be 1; fixing.

Hmmm, still a problem here. But I note that the error message: 

(EE) VIA(0): [drm] drmAgpAcquire failed 1023

did not come up! I wonder if that means it will work now, as soon as this console issue is fixed? 

emerge xterm

Fixed the xterm problem, and now X starts. Now when I run mplayer:

MPlayer interrupted by signal 11 in module: decode_video
- MPlayer crashed by bad usage of CPU/FPU/RAM.
 Recompile MPlayer with --enable-debug and make a 'gdb' backtrace and
 disassembly. Details in DOCS/HTML/en/bugreports_what.html#bugreports_crash.
- MPlayer crashed. This shouldn't happen.
 It can be a bug in the MPlayer code _or_ in your drivers _or_ in your
 gcc version. If you think it's MPlayer's fault, please read
 DOCS/HTML/en/bugreports.html and follow the instructions there. We can't and
 won't help unless you provide this information when reporting a possible bug.

Sometimes I also get the message: 

X Error of failed request:  BadWindow (invalid Window parameter)
  Major opcode of failed request:  2 (X_ChangeWindowAttributes)
  Resource id in failed request:  0xe0000b
  Serial number of failed request:  118
  Current serial number in output stream:  123

I get the same message (or similar) when I play mplayer with "-vo xv" or try xine, so I guess it's an X problem, independant of the player or codec. If I try to scale the output with "-vf scale=640:480" I get

vd_ffmpeg: Unexpected init_vo error

And the shell hangs afterwards (returns to prompt, then hangs). Pressing CTRL-C and then entering "reset" restores the shell. 

mplayer -vo x11 ntv-dvbs.mpeg

does work, opens a small window with the video playing, but of course without mpeg acceleration.

(still beeing edited)

Install XviD 

cvs -z3 -d:pserver:anonymous@cvs.xvid.org:/xvid login
cvs -z3 -d:pserver:anonymous@cvs.xvid.org:/xvid co xvidcore
cd xvidcore/build/generic
./bootstrap.sh
./configure
make && make install

Install Mplayer 

cd /usr/src/mplayer
cvs -d:pserver:anonymous@mplayerhq.hu:/cvsroot/mplayer login
cvs -z3 -d:pserver:anonymous@mplayerhq.hu:/cvsroot/mplayer co -P main
cvs -d:pserver:anonymous@mplayerhq.hu:/cvsroot/ffmpeg login
cvs -z3 -d:pserver:anonymous@mplayerhq.hu:/cvsroot/ffmpeg co -P ffmpeg
cp -r ffmpeg/libav* main
wget http://www.openchrome.org/snapshots/mplayer/mplayer-uni-20060101.diff
cd main

./configure --enable-xvmc --with-xvidlibdir=/usr/local/lib/ --with-xvidincdir=/usr/src/xvidcore/src/

make && make install

Then see if it works:
