Re: Re: No sound - Solaris x86

Concerning the performance of ogle on Solaris/x86, I wrote:

   The only disappointment is that a 400 MHz Pentium II with 128MB and
   a ATI Rage Pro can do more than 20 fps in simple tests with Linux,
   but is slower by a factor close to 3 with Solaris 8.

This was unfair to Solaris, which was running display depth 24 while
the fastest Linux timings were run in 16-bit depth.  The factor is
closer to 2 if both run at 24-bit depth.

ogle-0.9.2/mpeg2_video/yuv2rgb_mmx.c uses the single-instruction
multiple-data (MMX) registers for depth 16.  At 24-bit depth, ogle
advises "No accelerated colorspace coversion found".  I do not
understand this well enough to know if 24-bit depth could benefit from
SIMD.
