[Ffmpeg-devel] profiling libavcodec

I want to analyse the bottleneck of libavcodec on the MPEG2 decoding

So I enabled gprof and played a MPEG2 TS using ffplay.

But the results I've found are not very good:

% time     secs     secs      calls   ms/call ms/call  name
100.00      0.01     0.01     1666     0.01     0.01  video_image_display

So I disabled the graphical display, but, then, all functions appear with %
execution time = 0%.

Can anyone help me?
