Fred Eisele <[email protected]> added the comment: I got a build with ./configure --enable-debug --enable-libfaac --enable-libmp3lame --disable-optimizations I had to compile libavcodec/x86/dsputil_mmx.c without disabling-optimizations because... libavcodec/x86/dsputil_mmx.c:681: error: can't find a register in class ‘GENERAL_REGS’ while reloading ‘asm’ Shouldn't there be a C version of this function for debugging? Anyway.

Is there any other information I can harvest that will help? ____________________________________________________ FFmpeg issue tracker <[email protected]> <https://roundup.ffmpeg.org/roundup/ffmpeg/issue855> ____________________________________________________
