* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-27
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* avcodec/mpegaudiodec: Hardcode tables to save spaceAndreas Rheinhardt2020-12-08
| | | | | | | | | | | | | | | | | | | The csa_tables (which always consist of 32 entries of four byte each, but the type depends upon whether the decoder is fixed or floating-point) are currently initialized once during decoder initialization; yet it turns out that this is actually no benefit: The code used to initialize these tables takes up 153 (fixed point) and 122 (floating point) bytes when compiled with GCC 9.3 with -O3 on x64, so it is better to just hardcode these tables. Essentially the same applies to the is_tables: They have a size of 128B each and the code to initialize them occupies 149 (fixed point) resp. 140 (floating point) bytes. So hardcode them, too. To make the origin of the tables clear, references to the code used to create them have been added. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/mpegaudiodec: Make decoders init-threadsafeAndreas Rheinhardt2020-12-08
