* avcodec/on2avcdata: Combine tables for codebooksAndreas Rheinhardt2020-12-08
| | | | | | | Using one big table for the codebook symbols and lengths makes it possible to remove the pointers to the individual tables. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/on2avc: Use smaller tables for VLCsAndreas Rheinhardt2020-12-08
| | | | | | | | | | | | | | | | | | | | | | | | | The On2 audio decoder uses huge tables to initialize VLC tables. These tables (mostly) use symbols tables in addition to the codes tables and the lengths tables. This commit makes the codes tables redundant and removes them: If all tables are permuted so that the codes are ordered from left to right in the Huffman tree, the codes become redundant and can be easily calculated at runtime from the lengths (via ff_init_vlc_from_lengths()); this also avoids sorting the codes in ff_init_vlc_sparse()*. The symbols tables are always 16bit, the codes tables are 32bit, 16bit or (rarely) 8bit, the lengths tables are always 8bit. Even though some symbols tables have been used twice (which is no longer possible now because different permutations need to be performed on the code tables sharing the same symbol table in order to order them from left to right), this nevertheless saves about 28KB. *: If the initializations of the VLCs are repeated 2048 times (interleaved with calls to free the VLCs which have not been timed), the number of decicycles spent on each round of initializations improves from 27669656 to 7356159.

* avcodec/on2avc: Remove redundant code for freeingAndreas Rheinhardt2020-10-21

* avcodec/on2avc: Use least max_depth for get_vlc2()Andreas Rheinhardt2020-10-21
| | | | | | | | The longest codes of any VLC codebooks are 18 bits long and the VLC tables itself use 9 bits; therefore it is sufficient to read twice from the table, yet this has been done thrice. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/on2avc: Unify initializing quad and pair VLCsAndreas Rheinhardt2020-10-21
| | | | | | | | | | | | Up until now, quad VLCs are initialized with codes of type uint32_t, pair VLCs with codes of type uint16_t. There were two separate loops in the decoder's init function for each type of VLC. This commit unifies this: The type of the codes are now passed in as void * and the actual size of the codes is obtained from a table. This approach also allows to use the smallest type for each VLC code table: some quad tables actually fitted in uint16_t. This allows to remove about 7KB from the binary.

* | all: move ff_exp10, ff_exp10f, ff_fast_powf to lavu/ffmath.hGanesh Ajjanagadde2016-03-22
| | | | | | | | | | | | | | | | | | | | | | The idea is to use ffmath.h for internal implementations of math functions. Currently, it is used for variants of libm functions, but is by no means limited to such things. Note that this is not exported; use lavu/mathematics for such purposes. Reviewed-by: Ronald S.

| | | | | | | | | | | | | | | | | | | | | | Should fix the regression, and also speeds up table generation. Tables tested on GNU/Linux+clang: they are identical to the ones prior to 5495c7f. ff_exp10 caused one slight change in one entry, 50000 became 50001 due to somewhat incorrect rounding.
