In this case the gain should be obvious due to inlining. Nevertheless, here are new numbers. I chose vp6 for two reasons: 1. Above was for fraps-v2, giving vp6 for more "completeness". 2. stream_loop throws errors: Error while decoding stream #0:0: Invalid data found when processing input for fraps-v2. Here they are: vp6 (old): 78930 decicycles in qsort, 1 runs, 0 skips 45330 decicycles in qsort, 2 runs, 0 skips 27825 decicycles in qsort, 4 runs, 0 skips 17471 decicycles in qsort, 8 runs, 0 skips 12296 decicycles in qsort, 16 runs, 0 skips 9554 decicycles in qsort, 32 runs, 0 skips 8404 decicycles in qsort, 64 runs, 0 skips 7405 decicycles in qsort, 128 runs, 0 skips 6740 decicycles in qsort, 256 runs, 0 skips 7540 decicycles in qsort, 512 runs, 0 skips 9498 decicycles in qsort, 1024 runs, 0 skips 9938 decicycles in qsort, 2048 runs, 0 skips 8043 decicycles in qsort, 4095 runs, 1 skips vp6 (new): 15880 decicycles in qsort, 1 runs, 0 skips 10730 decicycles in qsort, 2 runs, 0 skips 10155 decicycles in qsort, 4 runs, 0 skips 7805 decicycles in qsort, 8 runs, 0 skips 6883 decicycles in qsort, 16 runs, 0 skips 6305 decicycles in qsort, 32 runs, 0 skips 5854 decicycles in qsort, 64 runs, 0 skips 5152 decicycles in qsort, 128 runs, 0 skips 4452 decicycles in qsort, 256 runs, 0 skips 4161 decicycles in qsort, 511 runs, 1 skips 4081 decicycles in qsort, 1023 runs, 1 skips 4072 decicycles in qsort, 2047 runs, 1 skips 4004 decicycles in qsort, 4095 runs, 1 skips > > Timothy _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
