* lavfi/vf_srcnn: use avio_check instead of accessHendrik Leppkes2018-05-08
| | | | | | | The filter uses avio for file access already, and avio_check is portable. Fixes trac #7192.
* lavc/cfhd: use AV_CEIL_RSHIFT instead of deprecated FF_CEIL_RSHIFTClément Bœsch2018-05-08

* lavfi/swaprect: use AV_CEIL_RSHIFT instead of deprecated FF_CEIL_RSHIFTClément Bœsch2018-05-08

* lavfi/nlmeans: use AV_CEIL_RSHIFT instead of deprecated FF_CEIL_RSHIFTClément Bœsch2018-05-08

* fate/hapenc : remove tests due to inconsistent resultMartin Vignali2018-05-08

* lavfi/nlmeans: inline integral patch value functionClément Bœsch2018-05-08
| | | | | This prevents redundant position computation and make the code faster (1.1x faster overall).
* lavfi/nlmeans: use unsigned for the integral patch valueClément Bœsch2018-05-08
| | | | This value can not be negative.
* lavfi/nlmeans: reorder memory accesses in get_integral_patch_valueClément Bœsch2018-05-08
| | | | This doesn't seem to make much of a difference but it can't hurt.
* lavfi/nlmeans: move final weighted averaging out of nlmeans_planeClément Bœsch2018-05-08
| | | | | | | | | | | | | | | | This helps figuring out where the filter is slow: 70.53% ffmpeg_g ffmpeg_g [.] nlmeans_slice 25.73% ffmpeg_g ffmpeg_g [.] compute_safe_ssd_integral_image_c 1.74% ffmpeg_g ffmpeg_g [.] compute_unsafe_ssd_integral_image 0.82% ffmpeg_g ffmpeg_g [.] ff_mjpeg_decode_sos 0.51% ffmpeg_g [unknown] [k] 0xffffffff91800a80 0.24% ffmpeg_g ffmpeg_g [.] weight_averages (Tested with a large image that takes several seconds to process) Since this function is irrelevant speed wise, the file's TODO is updated.
* lavfi/nlmeans: switch from double to floatClément Bœsch2018-05-08
| | | | | Overall speed appears to be 1.1x faster with no noticeable quality impact.
* lavfi/nlmeans: make compute_safe_ssd_integral_image_c fasterClément Bœsch2018-05-08
| | | | | | | | | | | before: ssd_integral_image_c: 49204.6 after: ssd_integral_image_c: 44272.8 Unrolling by 4 made the biggest difference on odroid-c2 (aarch64); unrolling by 2 or 8 both raised 46k cycles vs 44k for 4. Additionally, this is a much better reference when writing SIMD (SIMD vectorization will just target 16 instead of 4).
* checkasm: add vf_nlmeans test for ssd_integral_imageClément Bœsch2018-05-08
|
* lavfi/nlmeans: add AArch64 SIMD for compute_safe_ssd_integral_imageClément Bœsch2018-05-08
| | | | | ssd_integral_image_c: 49204.6 ssd_integral_image_neon: 28346.8
* lavfi/nlmeans: use ptrdiff_t for linesizesClément Bœsch2018-05-08
| | | | | Similarly to previous commit, this will help writing SIMD code by not having manual zero-extension in SIMD code
* lavfi/nlmeans: add SIMD-friendly assumptions for compute_safe_ssd_integral_imageClément Bœsch2018-05-08
| | | | | | | | | SIMD code will not have to deal with padding itself. Overwriting in that function may have been possible but involve large overreading of the sources. Instead, we simply make sure the width to process is always a multiple of 16. Additionally, there must be some actual area to process so the SIMD code can have its boundary checks after processing the first pixels.
* lavfi/nlmeans: random code shuffling to help compilerClément Bœsch2018-05-08
| | | | This makes nlmeans_slice() slightly faster at least on GCC 7.3.
* avformat/segafilmenc - set keyframe bit correctlyGyan Doshi2018-05-08
| | | | | | | | As per https://web.archive.org/web/20020803104640/http://www.pcisys.net:80/~melanson/codecs/film-format.txt, the top bit of the info1 chunk is set as 1 for inter-coded frames and 0 otherwise.

* vaapi_encode_vp8: memset the the structure to 0Haihao Xiang2018-05-07
| | | | | | | The structure has reserved bytes, it is required to set the reserved bytes to 0 for future use. Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>
* cbs_h264: Need [] in the name when subscript is requiredHaihao Xiang2018-05-07

* configure: add missing dependencies to vf_srcnnJames Almer2018-05-06
| | | | | | | The access dependecy is temporary and should fix compilation with msvc until a proper fix is committed. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/libzvbi-teletextdec: allow -1 subtitle duration and make it the defaultMarton Balint2018-05-06
| | | | | | | Most decoders (pgssubdec, ccaption_dec) are using -1 or UINT32_MAX for a subtitle event which should be cleared at the next event. Signed-off-by: Marton Balint <cus@passwd.hu>

* avcodec/jpeg2000dec: Reduce the number of tile parts allocatedMichael Niedermayer2018-05-06
| | | | | | | | | | | | | | This is large enough for all jpeg2000 files i tested. If some need more then this should be changed to dynamic allocation. Dynamic allocation would need to be done carefully as these are many relatively small arrays so repeatly reallocating them would not be good. The decrease is a clean and simple solution assuming it works for all files.

* configure: add pkg-config check for zlibJan Ekström2018-05-06
| | | | | | It exists, so why not use it? Helps one get rid of additional search path related flags in addition to PKG_CONFIG_{PATH,LIBDIR} when utilizing a cross-prefix separate from the sysroot.
* lavf/bluray: translate a read of 0 to EOFJan Ekström2018-05-06
| | | | | | | Yet another case of forgotten 0 =! EOF translation. The libbluray documentation specifically mentions that a read of 0 is EOF. Reported by Fyr on IRC.
