* | lavfi/selectivecolor: fix neutral color filteringClément Bœsch2018-08-09
| | | | | | | | | | | | | | | | | | | | Neutrals are supposed to be anything not black (0,0,0) and not white (N,N,N). Previous neutral filtering code was too strict by excluding colors with any of its RGB component maxed instead of just the white color. Reported-by: Royi Avital <royiavital@yahoo.com>

* | vf_tonemap: Update hdr metadata with the new peak valueVittorio Giovara2018-08-06
| | | | | | | | | | Less effective than the approach in vf_tonemap_opencl because there is no peak detection, but it's still a good idea to implement this.
* | vf_tonemap_opencl: Move update_metadata() to a shared fileVittorio Giovara2018-08-06

* | vf_tonemap[_opencl]: Move determine_signal_peak() to a shared fileVittorio Giovara2018-08-06
| | | | | | | | The two functions are identical. Use the shared LumaCoeffients type too.
* | vf_tonemap: Fix logic for detecting the maximum peak of untagged sourcesVittorio Giovara2018-08-06
| | | | | | | | | | | | | | | | | | | | When there is no metadata attached to a frame, take into account both the PQ and HLG transfers, and change the HLG default value to 10: the value of 12 is the maximum range in scene referred light, but the reference OOTF maps this from 0 to 1000 cd/m² on the ideal HLG monitor. This matches what vf_tonemap_opencl does.

* | Update Changelog for lensfun addition and bump minorPaul B Mahol2018-07-15

* | Add lensfun filterStephen Seo2018-07-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Lensfun is a library that applies lens correction to an image using a database of cameras/lenses (you provide the camera and lens models, and it uses the corresponding database entry's parameters to apply lens correction). It is licensed under LGPL3. The lensfun filter utilizes the lensfun library to apply lens correction to videos as well as images. This filter was created out of necessity since I wanted to apply lens correction to a video and the lenscorrection filter did not work for me. While this filter requires little info from the user to apply lens correction, the flaw is that lensfun is intended to be used on indvidual images. When used on a video, the parameters such as focal length is constant, so lens correction may fail on videos where the camera's focal length changes (zooming in or out via zoom lens). To use this filter correctly on videos where such parameters change, timeline editing may be used since this filter supports it. Note that valgrind shows a small memory leak which is not from this filter but from the lensfun library (memory is allocated when loading the lensfun database but it somehow isn't deallocated even during cleanup; it is briefly created in the init function of the filter, and destroyed before the init function returns). This may have been fixed by the latest commit in the lensfun repository; the current latest release of lensfun is almost 3 years ago. Bi-Linear interpolation is used by default as lanczos interpolation shows more artifacts in the corrected image in my tests. The lanczos interpolation is derived from lenstool's implementation of lanczos interpolation. Lenstool is an app within the lensfun repository which is licensed under GPL3. v2 of this patch fixes license notice in libavfilter/vf_lensfun.c v3 of this patch fixes code style and dependency to gplv3 (thanks to Paul B Mahol for pointing out the mentioned issues). v4 of this patch fixes more code style issues that were missed in v3. v5 of this patch adds line breaks to some of the documentation in doc/filters.texi (thanks to Gyan Doshi for pointing out the issue). v6 of this patch fixes more problems (thanks to Moritz Barsnick for pointing them out). v7 of this patch fixes use of sqrt() (changed to sqrtf(); thanks to Moritz Barsnick for pointing this out). Also should be rebased off of latest master branch commits at this point. Signed-off-by: Stephen Seo <seo.disparate@gmail.com>
* | avfilter/drawtext: fix box sizingGyan Doshi2018-07-13
| | | | | | | | | | | | | | | | | | At present, box size is clipped to frame size before being drawn, which can lead to the box not fully covering animated text which is longer than one or both frame dimensions. Since ff_blend_rectangle correctly takes care of clipping, it is skipped here which results in correct box sizing

| | | | | | | | | | | | | | | | | | | | | | | | 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.
