* avcodec: add cdtoons decoderAlyssa Milburn2020-02-15
| | | | | | | This adds a decoder for Broderbund's sprite-based QuickTime CDToons codec, based on the decoder I wrote for ScummVM. Signed-off-by: Alyssa Milburn <amilburn@zall.org>

| | | | | There's just no reason not to when its so easy (albeit messy) and its also reducing the precision of all non-power-of-two transforms that use it.

* avcodec/dvdsub: Fix warning about incompatible pointer typeAndreas Rheinhardt2020-02-14
| | | | | | | | | | | | | | | Fixes "passing argument 2 of ‘strtoul’ from incompatible pointer type [-Wincompatible-pointer-types]" ("expected ‘char ** restrict’ but argument is of type ‘const char **’") for GCC and "passing 'const char **' to parameter of type 'char **' discards qualifiers in nested pointer types [-Wincompatible-pointer-types-discards-qualifiers]" for Clang. The cast itself is safe; it is only needed because strtoul itself is not const-correct.

* lavu/tx: implement 32 bit fixed point FFT and MDCTLynne2020-02-13
| | | | | | | | | | | | | | | | | | | | Required minimal changes to the code so made sense to implement. FFT and MDCT tested, the output of both was properly rounded. Fun fact: the non-power-of-two fixed-point FFT and MDCT are the fastest ever non-power-of-two fixed-point FFT and MDCT written. This can replace the power of two integer MDCTs in aac and ac3 if the MIPS optimizations are ported across. Unfortunately the ac3 encoder uses a 16-bit fixed point forward transform, unlike the encoder which uses a 32bit inverse transform, so some modifications might be required there. The 3-point FFT is somewhat less accurate than it otherwise could be, having minor rounding errors with bigger transforms. However, this could be improved later, and the way its currently written is the way one would write assembly for it. Similar rounding errors can also be found throughout the power of two FFTs as well, though those are more difficult to correct. Despite this, the integer transforms are more than accurate enough.
