* svq1dec: Unbreak the scratch buffer allocationMichael Niedermayer2014-12-14
| | | | | | | | | | | | | | | 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 7b588bb691644e1b3c168b99accf74248a24e3cf. 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>
* svq1: do not modify the input packetAnton Khirnov2014-08-06
| | | | | | | | | | | 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
* Replace all instances of avcodec_alloc_frame() with av_frame_alloc().Anton Khirnov2013-11-16

| | | | | | This makes svq1 independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>
* svq1dec: clip motion vectors to the frame size.Anton Khirnov2013-04-17
| | | | | | | Fixes invalid reads for corrupted files. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org
* svq1dec: check that the reference frame has the same dimensions as the ↵Anton Khirnov2013-04-17
| | | | | | | | | | 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
