* Remove unnecessary libavutil/(avutil|common|internal).h inclusionsAndreas Rheinhardt2022-02-24
| | | | | | | | | | Some of these were made possible by moving several common macros to libavutil/macros.h. While just at it, also improve the other headers a bit. Reviewed-by: Martin Storsjö <martin@martin.st> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
* libswscale/options: Add parent_log_context_offset to AVClassAndreas Rheinhardt2021-09-19
| | | | | | | | This allows to associate log messages from slice contexts to the user-visible SwsContext. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* swscale: rename sws_context_class to ff_sws_context_classAndreas Cadhalpun2015-10-29
| | | | | | | It is an internal swscale symbol and thus should not be exported. Reviewed-by: Michael Niedermayer <michael@niedermayer.cc> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>
* doc/scaler, swscale/options: use proper capitalizationGanesh Ajjanagadde2015-10-10
| | | | | | | | | | | | | Proper names should be capitalized in all user facing API as far as possible. The option names themselves have not been changed since: 1. We consistently keep option names in lower case. 2. Changing them would break existing scripts. The converse is also true: improper names should not be capitalized generally.

* swscale: add two spatially stable dithering methodsØyvind Kolås2014-03-25
| | | | | | | | | | | | | Both of these dithering methods are from http://pippin.gimp.org/a_dither/ for GIF they can be considered better than bayer (provides more gray-levels), and spatial stability - often more than twice as good compression and less visual flicker than error diffusion methods (the methods also avoids error-shadow artifacts of diffusion dithers). These methods are similar to blue/green noise type dither masks; but are simple enough to generate their mask on the fly. They are still research work in progress; though more expensive to generate masks (which can be used in a LUT) like 'void and cluster' and similar methods will yield superior results
* swscale/options: switch default to bicubicMichael Niedermayer2013-10-06

* swscale: make bilinear scaling the defaultwm42013-09-30
| | | | | | | | | Before this commit, sws_init_context() failed with an error if no scaler was explicitly set. Defaulting to something reasonable is better behavior. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
* sws: add dither enumMichael Niedermayer2013-08-15
| | | | | | | | | | | This allows specifying more dither algorithms without using up flags and without ambiguities. Also initialize the new field based on the flags and use it. Note, improving the logic of the checks is left to subsequent commits, this here only switches from flags to enum. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | The version number is useful to check the libavutil version against which the library was compiled at run-time, which in turn may be useful to deal with binary compatibility issues.
