Michael Niedermayer	741b56fcee	avcodec/svq1dec: Add assert to ensure "stages >= 0" This is currently always true, the assert protects against future changes to the code breaking this assumtation Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Luca Barbato	9b8c8a9395	svq1dec: Validate the stages value strictly It can be less than -1. Bug-Id: CID 1194397 / CID 1194398 CC: libav-stable@libav.org	10 years ago
Paul B Mahol	335c150ba1	avcodec/svq1dec: remove unneeded #include, there are no assert() Signed-off-by: Paul B Mahol <onemda@gmail.com>	10 years ago
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`. Bug-Id: 766 CC: libav-stable@libav.org Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago

Paul B Mahol	6dfa70f272	Correct few "ffmpeg" typos Signed-off-by: Paul B Mahol <onemda@gmail.com>	10 years ago
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>	10 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	10 years ago

Ronald S. Bultje	6caa44aa7d	svq1: Use hpeldsp instead of dsputil for half-pel functions This makes svq1 independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	ecff5acb5a	svq1dec: clip motion vectors to the frame size. Fixes invalid reads for corrupted files. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago
Anton Khirnov	b1bb8fb860	svq1dec: check that the reference frame has the same dimensions as the current one They can be different if the last keyframe failed to decode correctly. Fixes possible invalid reads in such a case. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago

Michael Niedermayer	0a373c31cb	svq1dec: dont export the qscale table.
