Hi! It might be a problem in configure, or a stupid user :-) It's FreeBSD-7.1/amd64. I've installed x264 through FreeBSD's ports collection, the version is indicated as 0.0.20081218 This might be a little old, but configure accepts it: ============ Checking for x264 ============ #include <inttypes.h> #include <x264.h> #if X264_BUILD < 65 #error We do not support old versions of x264. Get the latest from SVN. #endif int main(void) { x264_encoder_open((void*)0); return 0; } cc -Wundef -Wdisabled-optimization -Wno-pointer-sign -Wdeclaration-after-statement -std=gnu99 -Wall -Wno-switch -Wpointer-arith -Wredundant-decls -O4 -march=native -mtune=native -pipe -ffast-math -fomit-frame-pointer -Ilibdvdread4 -I. -I/usr/local/include -D_THREAD_SAFE -I/usr/local/include -L/usr/local/lib -ffast-math -liconv -lncurses -lpng -lz -ljpeg -lz -lbz2 -L/usr/local/lib -ltheora -logg -lamrnb -lamrwb -lxvidcore -lm -lXext -lX11 -lpthread -lXxf86vm -lGL -lfaac -lfaac -o /tmp/mplayer-conf--23372 /tmp/mplayer-conf--23372.c -lx264 -lpthread Result is: yes (in libavcodec: yes) ########################################## But it does not compile: (or, well, assemble... it's yasm 0.8.0.2194) In file included from h264.c:42: x86/h264_i386.h: In function 'decode_significance_x86': x86/h264_i386.h:41: warning: cast from pointer to integer of different size x86/h264_i386.h:42: warning: cast from pointer to integer of different size x86/h264_i386.h: In function 'decode_significance_8x8_x86': x86/h264_i386.h:94: warning: cast from pointer to integer of different size h264.c: In function 'pred_direct_motion': h264.c:1048: warning: assignment from incompatible pointer type h264.c:1049: warning: assignment from incompatible pointer type h264.c: In function 'filter_mb_fast': h264.c:6294: warning: dereferencing type-punned pointer will break strict-aliasing rules h264.c: In function 'filter_mb_dir': h264.c:6351: warning: initialization from incompatible pointer type h264.c:6352: warning: initialization from incompatible pointer type In file included from h264.c:8191: svq3.c: In function 'svq3_decode_init': svq3.c:870: warning: dereferencing type-punned pointer will break strict-aliasing rules {standard input}: Assembler messages: {standard input}:18: Error: `ff_h264_lps_range(%eax,%esi,2)' is not a valid 64 bit base/index expression {standard input}:28: Error: `ff_h264_norm_shift(%esi)' is not a valid 64 bit base/index expression {standard input}:30: Error: `ff_h264_mlps_state+128(%eax)' is not a valid 64 bit base/index expression {standard input}:42: Error: `-1(%ebx)' is not a valid 64 bit base/index expression {standard input}:45: Error: `ff_h264_norm_shift(%ecx)' is not a valid 64 bit base/index expression {standard input}:6511: Error: `ff_h264_lps_range(%eax,%esi,2)' is not a valid 64 bit base/index expression [-- saving the mail servers from 561 more error lines like this --] {standard input}:31004: Error: `ff_h264_lps_range(%eax,%esi,2)' is not a valid 64 bit base/index expression {standard input}:31014: Error: `ff_h264_norm_shift(%esi)' is not a valid 64 bit base/index expression {standard input}:31016: Error: `ff_h264_mlps_state+128(%eax)' is not a valid 64 bit base/index expression {standard input}:31028: Error: `-1(%ebx)' is not a valid 64 bit base/index expression {standard input}:31031: Error: `ff_h264_norm_shift(%ecx)' is not a valid 64 bit base/index expression gmake[1]: *** [h264.o] Error 1 gmake: *** [libavcodec/libavcodec.a] Error 2 _______________________________________________ MPlayer-users mailing list MPlayer-users@xxxxxxxxxxxx https://lists.mplayerhq.hu/mailman/listinfo/mplayer-users
