My OS and Software versions are: .- Mandrake 8.1 .- Kernel 2.4.18 .- Libc 2.2.4 .- Xfree86 4.1.0 .- gcc 3.0.1 .- ld 2.11.90.0.8 .- as 2.11.90.0.8 .- MPlayer CVS 20020730 .- XVid CVS 20020412 My Hardware and Drivers: .- CPU P-II 350Mhz .- RAM 192M .- VideoCard ATI Rage 128 Pro (ATI Xpert 2000) .- VideoDriver R128 .- SoundCard Creative Vibra16X PROBLEM: Firts of all I couldnt compile the software. It halts on line 153 of libmpcodecs/vd_xvid.c. I solved this by changing the file to this: ifdef XVID_CSP_EXTERN XVID_DEC_PICTURE pic; endif because in this case dont use the XVID_DEC_PICTURE definition and dont blow up. Later, when i got it compiled, i tried to use the xvidx driver to see the movie and it works ok but in black and white. On last versions like the 20020410 CVS of MPlayer works the Xvid driver. I included the mplayer output as mplayer.log and the other files you need. Thanks for all. Gonzalo Alvarez Barrio. Spain. I THINK, THEN LINUX!
