- crc: fix signed overflow · 8b19ae07
  Mans Rullgard authored Oct 08, 2011
```
This fixes a signed overflow from i << 24 when i == 255 by
making i unsigned.  The result of the shift is already
assigned to an variable of unsigned type.

lavf: fix signed overflow in avformat_find_stream_info() · a31e9f68

Mans Rullgard authored Oct 08, 2011

On the first iteration through this code, last_dts is always
INT64_MIN (AV_NOPTS_VALUE) and the subtraction overflows in
an invalid manner.  Although the result is only used if the
input values are valid, performing the subtraction is still
not allowed in a strict environment.

Mans Rullgard authored Oct 08, 2011

In addition to avoiding undefined behaviour, an unsigned type
makes more sense for packing multiple 8-bit values.

put_bits: fix invalid shift by 32 in flush_put_bits() · ac6eab14

Mans Rullgard authored Oct 08, 2011

If flush_put_bits() is called when the 32-bit buffer is empty,
e.g. after writing a multiple of 32 bits, and invalid shift by
32 is performed.  Since flush_put_bits() is called infrequently,
this additional check should have negligible performance impact.
