Some xine guys are aware of my experiments comparing multimedia performance in latest kernels (2.4.x and 2.5.x), so instead of preparing a lengthy email i've just put a page with it. At this text i present a dummy multimedia simulator which pretends to be a video player and measures the number of frames that would be dropped (and also the mean latency). I used ConTest script to generate the background loads and take some interesting results. I hope this will be useful not only to improve xine but also kernel support in general for any other multimedia player. http://cambuca.ldhs.cetuc.puc-rio.br/~miguel/multimedia_sim/ Any comments, flames, etc are apreciated (that is, not the flames :) l-k people, please cc me, i'm not subscribed. regards, Miguel Freitas - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
