* avutil/tree: add additional const qualifier to the comparatorGanesh Ajjanagadde2015-10-24
| | | | | | | | | | | | | libc's qsort comparator has a const qualifier on both arguments. This adds a missing const qualifier to exactly match the comparator API. Existing usages of av_tree_find, av_tree_insert are appropriately modified: type signature changes of the comparators, and removal of unnecessary void * casts of function pointers.

* | avutil/mathematics: speed up av_gcd by using Stein's binary GCD algorithmGanesh Ajjanagadde2015-10-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This uses Stein's binary GCD algorithm: https://en.wikipedia.org/wiki/Binary_GCD_algorithm to get a roughly 4x speedup over Euclidean GCD on standard architectures with a compiler intrinsic for ctzll, and a roughly 2x speedup otherwise. At the moment, the compiler intrinsic is used on GCC and Clang due to its easy availability. Quick note regarding overflow: yes, subtractions on int64_t can, but the llabs takes care of that. The llabs is also guaranteed to be safe, with no annoying INT64_MIN business since INT64_MIN being a power of 2, is shifted down before being sent to llabs. The binary GCD needs ff_ctzll, an extension of ff_ctz for long long (int64_t). On GCC, this is provided by a built-in. On Microsoft, there is a BitScanForward64 analog of BitScanForward that should work; but I can't confirm. Apparently it is not available on 32 bit builds; so this may or may not work correctly. On Intel, per the documentation there is only an intrinsic for _bit_scan_forward and people have posted on forums regarding _bit_scan_forward64, but often their documentation is woeful. Again, I don't have it, so I can't test. As such, to be safe, for now only the GCC/Clang intrinsic is added, the rest use a compiled version based on the De-Bruijn method of Leiserson et al: http://supertech.csail.mit.edu/papers/debruijn.pdf. Tested with FATE, sample benchmark (x86-64, GCC 5.2.0, Haswell) with a START_TIMER and STOP_TIMER in libavutil/rationsl.c, followed by a make fate. aac-am00_88.err: builtin: 714 decicycles in av_gcd, 4095 runs, 1 skips de-bruijn: 1440 decicycles in av_gcd, 4096 runs, 0 skips previous: 2889 decicycles in av_gcd, 4096 runs, 0 skips Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* | avutil/attributes: add av_warn_unused_resultGanesh Ajjanagadde2015-10-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | GCC 3.4 introduced an attribute warn_unused_result to warn when a programmer discards the return value. Applying this judiciously across the codebase can help in fixing a lot of problems. At a high level, functions which return error codes should always be checked. More concretely, consider the functions ff_add_format and the like in avfilter/formats.h. A quick examination shows that a large portion of libavfilter fails to handle the associated errors, usually AVERROR(ENOMEM). The above example was where I observed the utility of this, but it should be useful in many places across the code base.
