Laurent Aimar	46b004959b	ffv1: Fixed size given to init_get_bits() in decoder. init_get_bits() takes a number of bits and not a number of bytes as its size argument. Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Anton Khirnov	ec6402b7c5	lavc: use designated initialisers for all codecs. It's more readable and less prone to breakage.	14 years ago

Michael Niedermayer	294e5475c2	ffv1: fix undefined behavior with insane widths. The new tables is large enough to prevent this together with our image size checks. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Anton Khirnov <anton@khirnov.net>	14 years ago
Diego Biurrun	0a6b1a9f21	Replace int_fast integer types with their sized standard posix counterparts. The _fast integer types provide no realworld benefits, but may introduce portability issues and are just plain ugly.	14 years ago
