* avutil/common: Don't auto-include mem.hAndreas Rheinhardt2024-03-31
| | | | | | | | | | | There are lots of files that don't need it: The number of object files that actually need it went down from 2011 to 884 here. Keep it for external users in order to not cause breakages. Also improve the other headers a bit while just at it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* opus_silk: reset midonly flag after skipping LBRRTristan Matthews2022-09-23

* avcodec/opus_silk: Remove wrong size information in function declarationAndreas Rheinhardt2021-09-20
| | | | | | | | | | | | | | | | silk_lsp2poly()'s declaration contained arrays with array sizes; yet these array sizes exceeded the number of actually accessed array elements (which is related to another parameter) and this leads to -Wstringop-overflow= warnings from GCC 11, because the arrays provided by callers are only large enough for the actually used elements. So replace the incorrect array sizes with comments containing the correct array sizes. Given that these sizes are not compile-time constants, they can only be communicated via a comment.

| * opus: Fix typo causing overflow in silk_stabilize_lsfAndreas Cadhalpun2015-12-16
| | | | | | | | | | | | | | | | | | | | Due to this typo max_center can be too large, causing nlsf to be set to too large values, which in turn can cause nlsf[i - 1] + min_delta[i] to overflow to a negative value, which is not allowed for nlsf and can cause an out of bounds read in silk_lsf2lpc.
