Michael Niedermayer	5a82ad644f	svq1dec: Unbreak the scratch buffer allocation The input packets are always assumed to be padded and the av_fast_ family of function takes a pointer to a pointer. Thanks to Nicolas Dufresne <nicolas.dufresne@collabora.com> for a similar patch. Introduced in `7b588bb691`.

Michael Niedermayer	4213fc5b9e	avcodec/svq1dec: Fix multiple bugs from "svq1: do not modify the input packet" Add padding, clear size, use the correct pointer. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	7b588bb691	svq1: do not modify the input packet The input data must remain constant, make a copy instead. This is in theory a performance hit, but since I failed to find any samples using this feature, this should not matter in practice. Also, check the size of the header, avoiding invalid reads on truncated data. CC:libav-stable@libav.org	11 years ago
