[FFmpeg-devel] gprof and FFmpeg
Thu Jun 19 08:23:14 CEST 2008
I would like to profile certain portions of FFmpeg using gprof. But when
I try to compiler FFmpeg using the --enable-gprof option, the
compilation process dies of register exhaustion. Yeah, you know the
error: "can't find a register in class 'GENERAL_REGS' while reloading
'asm'". This is with 4.1.3 and 4.3.0 on x86_32.
Has anyone tried using gprof with FFmpeg lately? I try using oprofile
but I rarely have much luck getting it set up.
