* Adds TensorFlow backend for dnn inference module.Sergey Lavrushkin2018-06-05

* avfilter/drawtext: present 'hms' formatted 'pts' in 24h formatVishwanath Dixit2018-06-04
| | | | | | | | | | | | HMS is formatted as HH:MM:SS.mmm, but, HH part is not limited to 24 hours. For example, the the drawn text may look like this: 243029:20:30.342. To present the timestamp in more readable and user friendly format, this patch provides an additional option to limit the hour part in the range 0-23. Note: Actually the above required format can be obtained with format options 'localtime' and 'gmtime', but, milliseconds part is not supported in those formats.

* lavfi/Makefile: move dnn_*.o under vf_srcnnJan Ekström2018-06-02
| | | | | | | | | | | These files depend on libavformat, and the vf_srcnn filter currently is the only thing utilizing these dnn_* files and already happens to have a dependency on libavformat. This fixes compilation in cases where libavformat is not a dependency for libavfilter. Reported by Kam_ on IRC.

* 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.

* 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).
* 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.
