  1. Wrong, a straight class with no virtual functions...

    Wrong, a straight class with no virtual functions has no "meta" to it, the only time you start using virtual functions is when they make sense, i.e. the benefit ratio is high, meaning....that it...

    There is truth to that. In a nutshell you take advantage of the language extended features in performance non-critical code, and you focus your attention on performance where it counts.

    Any one...
  3. Don't know what you've been smoking, but you have...

    Don't know what you've been smoking, but you have the same memory management capabilies in C++ that you do in C. You must be confused with C#. One of the gripes that C# and Java fans have about...

    Spoken like someone living in the 90's...show me modern evidence that C++ is slower than C doing the same job.

    Unfortunately no, I don't have avx2 either. Maybe someone else can test that.

    I think you mis-understanding the code.

    The existing compile verifies that the compiler supports the required switch for compiling sse4.1 code. If it does, then it compiles the sse4.1 version,...
  7. SSE2/SSE41/AVX2 patch

    This version is better, since it takes alignment into consideration when deciding whether to call the vector code.

  8. SSE2/SSE41/AVX2 patch

    I agree, therefore I have come up with a new patch which implements all three approaches.

    Also calling the vector code is only triggered when it would yield an improvement in performance, maybe...
  9. Support for CPUS that aren't SSE4.1 capable patch

    I threw together a patch which adds an SSE2 version for those CPU's that aren't SSE4.1 capable after reading this page.

  10. More realistic benchmark results

    These are my results for a stock FX-9590 in s Sabertooth 990FX R2 motherboard.

    These results are more realistic in that they don't...

    It isn't that any one "average" program consumes the ram directly. It's really a matter of what Linux can do with ram that is freely available to improve the overall experience. It is also known...

    Yes, if you're throwing something together for cheap, by all means reuse parts if you can get away with it.

    But really the main point is if you've got $300-$600 invested in a machine, $30-$40 for...

    New results (much closer to reality)

    Yes,

    I can't blame anyone for "wrong" results. All I can say is that my results with the cheapo MSI motherboard and 8G of good ram paint an entirely different picture. From these results you are...

    Working well on Radeon 4200 mobile (with a new patch)

    I tried the old way Xvba/Va in the past and it just didn't work well enough.

    I built the new XbmcXvba and I'm quite pleased with how it's performing. I had a crash when I was toggling between...

    Pop in an Nvidia GT430 and be done with it

    Well, I went through the trouble of testing out the vaapi/fglrx/e-350 route just so I knew whether it was worthwhile or not.
    Since I build all my own packages I was able to get it working about as...

    While it's true that a typical CPU today can handle video decode without problems, keep in mind that GPU acceleration can decode video for less power. Power in this sense can be taken two ways. One,...

    I forgot to mention Nvidia's VDPAU. With VDPAU you can watch videos with very little CPU utilization. I think VDPAU was added starting with the 2XX cards. The latest Adobe flash player now uses...
