Michael Niedermayer	3a0a2f33a6	libavutil: add AV_QSORT() about 2-5 times faster than gnu libcs qsort() And should be 100% binary identical across platforms. I will bump the version once the API is certainly stable and everyone is happy with the API. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	2012-06-18 16:32:31 +02:00
