* Remove unnecessary libavutil/(avutil|common|internal).h inclusionsAndreas Rheinhardt2022-02-241-1/+1
| | | | | | | | | | 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>

| | | | | | | | | | This avoids spurious library rebuilds when only the test program code is changed and simplifies the build system.

| | | | | | | | | | | | | | | | | | Currently, standard tables like AV_CRC_32_IEEE and such are being generated (or provided in case the user compiles with hardcoded tables) with only 257 elements. We're missing a considerable boost in performance by not making them with a size of 1024 elements instead. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
