you could check the FC19(build with mips3 instruction set) system on the Loongson-3A-780E machine. it only has /lib/ forlder, but the CentOS6.4-MultiLib has /lib/, /lib32/ and /lib64. /lib/ is O32 API, /lib32/ is N32 API and /lib64 is N64 API. i think it's ok for ffmpeg to use MIPS64 instruction set on a 32bit OS, because our kernel has 64bit API and the ffmpeg-2.1.7-1.loongson installed in the FC19 works correctly. by the way, the system BACKUP on the machine is build with mips64r2 instruction set and it works faster than FC19. how do you think? _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
