ffmpegX and AltiVec

[wullimann]

Hi!

Why is ffmpeg in ffmpegX not compiled, with the option:

--powerpc-perf-enable
?

I built the latest version on my mac with
--tune=7450 --powerpc-perf-enable

But since I don't have faac, faad and various other application installed on my mac, my output was rather useless. Can anyone provide a build of ffmpeg including all other helpers and with the "--powerpc-perf-enable " option enabled?

Regards,
Martin

The altivec optimizations are enabled in the included ffmpeg binary.

The altivec optimizations are enabled in the included ffmpeg binary.

Is it? The version of ffmpeg included in ffmpegX 0.0.9 is bulit with the following options:

Wullimanns-PowerBook:/Applications/Multimedia/ffmpegX.app/Contents/Resources mamu$ ./ffmpeg -version
ffmpeg version 0.4.9-pre1, build 4731, Copyright (c) 2000-2004 Fabrice Bellard

libavformat 4621

The ppc-option is not listed.

The altivec optimizations are automatically enabled during the configuration and they result in the use of the -faltivec flag. The --powerpc-perf-enable option is a specialized option which will use the PMC registers (enabled by using Monster, from the Apple CHUD utilities) to display a performance report, mostly useful for the programmers who have to optimize the code.
