* avcodec/mpegaudio_tablegen: more dynamic table creation speedupsGanesh Ajjanagadde2015-12-01
| | | | | | | | | | | | | | | | | | | | This further speeds up runtime initialization, with identical generated tables. Sample benchmark (x86-64, Haswell, GNU/Linux): old: 34441423 decicycles in mpegaudio_tableinit, 8192 runs, 0 skips new: 10776291 decicycles in mpegaudio_tableinit, 8192 runs, 0 skips Most low hanging fruit is taken care of here. For some idea, note that 83,064 array elements totalling 233,722 bytes need to be initialized. Thus, with this patch, we average ~ 12.9 cycles per element or ~ 4.6 cycles per byte.

* avcodec/mpegaudio_tablegen: speed up dynamic table creationGanesh Ajjanagadde2015-12-01
| | | | | | | | | | | | | | | | | | | This does some miscellaneous stuff mainly avoiding the usage of pow to achieve significant speedups. This is not speed critical, but is unnecessary latency and cycles wasted for a user. All tables tested and are identical to the old ones (bit-exact even in floating point case). Sample benchmark (x86-64, Haswell, GNU/Linux): old: 102329530 decicycles in mpegaudio_tableinit, 1 runs, 0 skips new: 34111900 decicycles in mpegaudio_tableinit, 1 runs, 0 skips Reviewed-by: Ronald S.

* avutil/tablegen: add tablegen libm compatibility shimsGanesh Ajjanagadde2015-12-01
| | | | | | | | | | | | This is useful for build-time table generation (--enable-hardcoded-tables), by providing compat shims for hosts that have broken libms.

* avcodec/ac3: always use hardcoded tablesGanesh Ajjanagadde2015-11-30
| | | | | | | | | | | | | | | | | The table in question is a 253 byte one. In fact, it turns out that dynamic generation of the table results in an increased binary size. Code compiled with GCC 5.2.0, x86-64 (size in bytes), before and after patch: old: 62321064 libavcodec/libavcodec.so.57 new: 62320536 libavcodec/libavcodec.so.57 Thus, it always make sense to statically allocate this.

* AAC encoder: make pe.min a local minimumClaudio Freire2015-11-29
| | | | | | | | | | | | | | As noted in a comment, pe.min in the reference encoder is centered around current pe. The bit reservoir algo needs pe.min to be a local minimum, because it can only account for local PE variations. If it's set to a global minimum as was being done, bit reservoir logic doesn't work as efficiently. This patch tries to forget old minimums and converge to a local minimum without losing the stability of the previous solution. Listening tests until now suggest this solves numerous RC issues.
