- mpegencts: Fix overflow in cbr mode period calculations · 64f7db55
  Timo Teräs authored Nov 28, 2015
```
ts->mux_rate is int (signed 32-bit) type. The period calculations
will start to overflow when mux_rate > 5mbps. This fixes overflows
by converting first to 64-bit type.

Fixes #5044.

thus be signed or the code setting it needs to use 0 as error code
the type of the field could be changed as well but its in an installed header

avutil/crc: avoid needless space wastage of hardcoded crc table · 1bb7db21

Ganesh Ajjanagadde authored Nov 30, 2015

There was no reason AFAIK for making AV_CRC_24_IEEE 12. This simply
resulted in wasted space under --enable-hardcoded-tables:
dynamic: 1318672 libavutil/libavutil.so.55
old    : 1330680 libavutil/libavutil.so.55
new    : 1326488 libavutil/libavutil.so.55

Minor version number is bumped, with ifdefry due to API breakage.
