* lavfi/deshake: fix deshake crash issue.Jun Zhao2018-10-06
| | | | | | | | | | | | | | | | | | | | | | | | Fixes ticket #7441. for block contrast calculate, the block is like this: |<---------------- stride-----------------------| +-----------------------------------------------> X | | w = 16 | (cx,cy)+------+ | | | |h=blocksize| | | | | | +------+ V Y so we calc the block contrast use: (cy + y) * stride + (cx + x) Signed-off-by: Jun Zhao <mypopydev@gmail.com>
* lavfi/deshake: Check alignment before calling asm init function.Carl Eugen Hoyos2018-03-20
| | | | | | | Do this for every frame to make sure dynamic filters do not cause crashes. Fixes ticket #7078.
* lavu,lavfi,ffmpeg: Remove experimental OpenCL APIMark Thompson2017-11-22
| | | | | | | | | | | This was added in early 2013 and abandoned several months later; as far as I can tell, there are no external users. Future OpenCL use will be via hwcontext, which requires neither special OpenCL-only API nor global state in libavutil. All internal users are also deleted - this is just the unsharp filter (replaced by unsharp_opencl, which is more flexible) and the deshake filter (no replacement).

* avutil: Rename FF_CEIL_COMPAT to AV_CEIL_COMPATDerek Buitenhuis2016-01-27
| | | | | | | | | | Libav, for some reason, merged this as a public API function. This will aid in future merges. A define is left for backwards compat, just in case some person used it, since it is in a public header. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

* all: use FFDIFFSIGN to resolve possible undefined behavior in comparatorsGanesh Ajjanagadde2015-11-03
| | | | | | | | | | | | | | | | | | | FFDIFFSIGN was created explicitly for this purpose, since the common return a - b idiom is unsafe regarding overflow on signed integers. It optimizes to branchless code on common compilers. FFDIFFSIGN also has the subjective benefit of being easier to read due to lack of ternary operators. Tested with FATE. Things not covered by this are unsigned integers, for which overflows are well defined, and also places where overflow is clearly impossible, e.g an instance where the a - b was being done on 24 bit values.

* avfilter/vf_deshake: replace qsort with AV_QSORTGanesh Ajjanagadde2015-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | qsort is called indirectly in filter_frame, suggesting its performance criticality. AV_QSORT is substantially faster due to the inlining of the comparison callback. Thus, the increase in performance should be worth the increase in binary size. This optimization is just a low hanging fruit. The trac ticket 1430 is a request for an improved deshake filter. Sample benchmark (x86-64, Haswell, GNU/Linux): File: original from https://trac.ffmpeg.org/ticket/1430 command: ffmpeg -stream_loop 8 -i file.webm -vf deshake=rx=64:ry=64 -f null - Timer truncated at 1024 runs. new: 28260 decicycles in qsort, 1 runs, 0 skips 35570 decicycles in qsort, 2 runs, 0 skips 39010 decicycles in qsort, 4 runs, 0 skips 46897 decicycles in qsort, 8 runs, 0 skips 40442 decicycles in qsort, 16 runs, 0 skips 41611 decicycles in qsort, 32 runs, 0 skips 40345 decicycles in qsort, 64 runs, 0 skips 38967 decicycles in qsort, 128 runs, 0 skips 38647 decicycles in qsort, 256 runs, 0 skips 40238 decicycles in qsort, 512 runs, 0 skips 39676 decicycles in qsort, 1024 runs, 0 skips old: 1740280 decicycles in qsort, 1 runs, 0 skips 923560 decicycles in qsort, 2 runs, 0 skips 511330 decicycles in qsort, 4 runs, 0 skips 309720 decicycles in qsort, 8 runs, 0 skips 194900 decicycles in qsort, 16 runs, 0 skips 142686 decicycles in qsort, 32 runs, 0 skips 112516 decicycles in qsort, 64 runs, 0 skips 98166 decicycles in qsort, 128 runs, 0 skips 88147 decicycles in qsort, 256 runs, 0 skips 88706 decicycles in qsort, 512 runs, 0 skips 86783 decicycles in qsort, 1024 runs, 0 skips Reviewed-by: Nicolas George <george@nsup.org> Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Ganesh Ajjanagadde <gajjanagadde@gmail.com>
* avfilter/vf_deshake: use a void * comparator for consistencyGanesh Ajjanagadde2015-10-24
| | | | | | | | | | | For generality, qsort uses a comparator whose elements are void *. This makes the comparator have such a form, and thus makes the void * cast of the comparator pointer useless. Furthermore, this makes the code more consistent with other usages of qsort across the codebase.
