I retested with gcc 3.3.5 on x86 as requested as well as 2.95.4 on
PPC.
Result:
x86:
libmpeg2 0.4.0 is up to 5% faster than 0.3.1, but gcc 3.3.5 gives up
to a 5% slowdown compared to 2.95.4.
For FFmpeg "lavdopts idct=4" no longer is an improvement, but
"lavdopts fast" is still the quickest.
When comparing FFmpeg and libmpeg2, libmpeg2 no longer is the clear
winner, it's faster (7%) for bomb.mpeg, but slower for heist60.mpeg
(5%) and dvd.mpeg (8%).
PPC:
FFmpeg is clearly faster than libmpeg2 when compiled with gcc 2.95.4,
but since 2.95.4 barely reaches 50% (!) of the performance of 3.3.5 I
think these numbers can be ignored. Apparently gcc 3.x is one hell of
an improvement over 2.95.x on PPC.
Conclusion:
It might be interesting to benchmark with gcc 3.4 or 4.0 as well since
I found 3.4 to be the same speed as 2.95 in a compiler benchmark a
long time ago, while 3.3.x was the absolute low point.
The race between FFmpeg and libmpeg2 is not completely decided.
Somebody should go ahead and speed up FFmpeg a bit to tilt the scales
in FFmpeg's favor ;-)
