Haswell だと、最も高速化が期待できる「デコード速度優先でネイティブな色空間へのデコード」で 25% 程度の高速化になります。速い！

    Hey there. I’ve encountered a few (reproducible) crashes in a few of your codecs. I’d consider myself a pretty good C++ programmer (although I’ve never touched codecs before) so I’ll try to debug them myself. If you’re interested in some of the debugging info I can provide, you can contact me at ibemad@gmail.com.

    Hmm. Could you tell me the reproducibility conditions here?

    I’m using dxtory to record in source-powered games (Left 4 Dead 2, Team Fortress 2). Whenever I try to record in either of those games using RGB or RGBA codecs, the game crashes instantly. If I use any of the other codecs (the YUV ones), they record fine, but if I try to open them it crashes the media player (crashes VirtualDub and Windows Media Player).

    I’m using Windows 7 x64 and Dxtory 2.0.123. I have an AMD Phenom II x4 965 @ stock 3.4 GHz, 8GB ram, AMD Radeon HD 6870.

    It’s a 100% reproducible crash, so I have a feeling that it probably has something to do with my hardware configuration or something else you have no way of testing on your side, otherwise you’d notice a bug like this immediately.

    All right. I have some more questions.
    1: Do older versions of codec (like 13.1.0 and 12.0.1) crash similarly?
    2: Do other games crash similarly?

    I have fixed the bug. It’s a very stupid bug…
    13.2.1 will be released soon.

    :D Thanks, it works great now.
