| | | | | | | | | | | | | | | | | | | | Currently all uses of the emu edge code as well as the code itself assume int linesize changing some but not changing all would introduce a security issue once all use this typedef a simple search and replace can be done to switch them all to ptrdiff_t Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* lavc: introduce VideoDSPContextRonald S. Bultje2012-12-201-0/+71
Move some functions from dsputil. The idea is that videodsp contains functions that are useful for a large and varied set of video decoders. Currently, it contains emulated_edge_mc() and prefetch(). Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
