[MPlayer-users] Dark video on DivX playback

[Roland Häder]

Hi,

I have tried to play a DivX video but I only can hear the sound track and I 
can see a dark video window.

I got the latest CVS of mplayer. The configuration script tells me:

  Enabled optional drivers:
    Input: streaming tv-v4l edl tv mpdvdkit2 vcd 
    Codecs: qtx xvid dshow/dmo win32 libvorbis liblzo 
    Audio output: alsa9 oss sdl mpegpes(dvb) 
    Video output: xvidix sdl vesa jpeg png mpegpes(dvb) fbdev svga aa ggi 
opengl dga xv x11 
  Disabled optional drivers:
    Input: tv-bsdbt848 cdda dvdnav dvdread dvdcss 
    Codecs: opendivx divx5linux divx4linux libdv libavcodec real xanim libmad 
    Audio output: sgi sun esd arts dxr2 nas win32 
    Video output: bl zr dxr3 dxr2 directx gif89a xmga mga directfb tdfxfb 3dfx 


Here's the entry from configure.log:

Looks like it's working, but as I said the video is pitch black. :(

I have backtraced it and ends up at the avifile project at sourceforge.net. 
Also latest CVS.

When I try to compile it (the deb's also didn't work) I can found this in 
config.log:

configure:18013: checking for decore in -ldivxdecore

Some versions:

GNU ld version 2.12.90.0.1 20020307 Debian/GNU Linux

I hope that's all enougth for you dev-guys. :) If you need more info, let me 
know it.

Chears,
