Mans Rullgard	8b19ae0761	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. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Marton Balint	cbfca6225a	avutil: bump minor version because of av_get_default_channel_layout type fix Well, probably an ABI breakage at least for 32bit, but hopefully it will go unnoticed because the fix happened realtively soon.

David Goldwich	b3e144a7df	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.

Anton Khirnov	4dbcdfa86d	AVOptions: remove AVOption.offset <= 0 checks They will only ever be <=0 if the option is broken, in which case this check is hiding a bug.	13 years ago
Anton Khirnov	79eff91325	AVOptions: deprecate av_opt_set_defaults2 It's a hack which was created to allow for multiple options with different defaults to refer to same field (e.g. 'b' vs 'ab'). There is no need for it anymore.	13 years ago
