Jun Zhao	b30575bc98	checkasm/sw_rgb: fix the function declaration warning fix the warning: "function declaration isn’t a prototype", in C int foo() and int foo(void) are different functions. int foo() accepts an arbitrary number of arguments, while int foo(void) accepts 0 arguments.

Timo Rothenpieler	baabd3c2ad	avcodec/nvdec: avoid needless copy of output frame Replaces the data pointers with the mapped cuvid ones. Adds buffer_refs to the frame to ensure the needed contexts stay alive and the cuvid idx stays allocated. Adds another buffer_ref to unmap the frame when it's unreferenced itself.	7 years ago
Timo Rothenpieler	2e700b082c	Revert "avcodec/nvenc: make hw_frames_ctx fully optional" This reverts commit `7d4e1f7cfb`. Accidentially pushed this with a batch of other patches, and it didn't seem to break anything, so I went with it. Except it does, so reverting it it is.	7 years ago

Aman Gupta	1a14e39145	avformat/mpegts: use MAX_SECTION_SIZE instead of hardcoded value Signed-off-by: Aman Gupta <aman@tmm1.net>	7 years ago
Aman Gupta	2c500f5097	avformat/mpegts: skip non-PMT tids earlier This mimics the logic flow in all the other callbacks (pat_cb, sdt_cb, m4sl_cb), and avoids calling skip_identical() for non PMT_TID packets. Since skip_identical modifies internal state like MpegTSSectionFilter.last_ver, this change prevents unnecessary reprocessing on some streams which contain multiple tables in the PMT pid. This can be observed with streams from certain US cable providers, which include both tid=0x2 and another unspecified tid=0xc0. Signed-off-by: Aman Gupta <aman@tmm1.net>	7 years ago

Hendrik Leppkes	8007a86363	lavfi/vf_srcnn: use avio_check instead of access The filter uses avio for file access already, and avio_check is portable. Fixes trac #7192.	7 years ago

Clément Bœsch	e6114d21ac	lavfi/nlmeans: inline integral patch value function This prevents redundant position computation and make the code faster (1.1x faster overall).	7 years ago

Clément Bœsch	de956198a9	lavfi/nlmeans: reorder memory accesses in get_integral_patch_value This doesn't seem to make much of a difference but it can't hurt.	7 years ago
Clément Bœsch	34e1e53e28	lavfi/nlmeans: move final weighted averaging out of nlmeans_plane 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.	7 years ago
Clément Bœsch	667503ef68	lavfi/nlmeans: switch from double to float Overall speed appears to be 1.1x faster with no noticeable quality impact.	7 years ago
Clément Bœsch	43d16aef63	lavfi/nlmeans: make compute_safe_ssd_integral_image_c faster 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).	7 years ago

Clément Bœsch	5a71bce371	lavfi/nlmeans: add AArch64 SIMD for compute_safe_ssd_integral_image ssd_integral_image_c: 49204.6 ssd_integral_image_neon: 28346.8	7 years ago
Clément Bœsch	5ba14f4f1a	lavfi/nlmeans: use ptrdiff_t for linesizes Similarly to previous commit, this will help writing SIMD code by not having manual zero-extension in SIMD code	7 years ago
Clément Bœsch	26f02c51ce	lavfi/nlmeans: add SIMD-friendly assumptions for compute_safe_ssd_integral_image 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.	7 years ago
Clément Bœsch	f1248b7795	lavfi/nlmeans: random code shuffling to help compiler This makes nlmeans_slice() slightly faster at least on GCC 7.3.	7 years ago
