2011-10-12 16:51:16 +02:00

Just for naming consistency, no functional changes.

AVOptions: split get_number().
...
Split actual writing to read_number() in the same way as write_number().
Allows set_string_number() to write to a caller-provided destination.

AVOptions: add av_opt_get*, deprecate av_get*.
...
New functions can get values from child objects, properly report error
codes and have consistent naming and signatures.
2011-10-12 16:51:16 +02:00

AVOptions: add av_opt_set*().
...
Deprecate av_set_*
New functions support setting values on children, return error codes
instead of options and have consistent naming and signatures.

AVOptions: add new API for enumerating children.
...
This will allow the caller to enumerate child contexts in a generic way
and since the API is recursive, it also allows for deeper nesting (e.g.
AVFormatContext->AVIOContext->URLContext)
This will also allow the new setting/reading API to transparently apply
to children contexts.

intfloat_readwrite: fix signed addition overflows
...
These additions might overflow the signed range for large
input values. Converting to unsigned before the addition
rather than after avoids such undefined behaviour. The
result under normal two's complement wraparound remains
unchanged.

AVOptions: refactor set_number/write_number

address out of it.

AVOptions: split av_set_string3 into opt type-specific functions
...
Also stop attempting to honor the alloc parameter, as things break
horribly in that case.
It will be removed in upcoming successor to av_set_string3.

crc: fix signed overflow
...
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.

des: add possibility to calculate DES-CBC-MAC with small buffer
...
This patch adds the possibility to calculate the DES-CBC-MAC of a
source buffer (i.e. the last block of the buffer encrypted in CBC
mode) without having to allocate a destination buffer that is as
long as the complete source buffer, but instead only 8 bytes
for the MAC.
