Reimar Döffinger	af6e232ccf	VC1 VDPAU: Mark missing reference frames as such. Currently the code passes some nonsense values as references instead, causing corruption with NVidia's and assertion failures with Mesa's implementation. For non-corrupted input this mostly happens in interlaced bitstreams, e.g. http://samples.mplayerhq.hu/V-codecs/WMV9/interlaced/480i30__codec_WVC1__mode_2__framerate_29.970__type_2__preproc_17.wmv. The != VDP_INVALID handle assert does not trigger (and probably is quite nonsense) because the frames are initialized to 0. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	11 years ago

Martin Storsjö	d1d99e3bef	pcx: Check the packet size before assuming it fits a palette This fixes reads out of bounds. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	7ba0cedbfe	rpza: Fix a buffer size check We read 2 bytes for 15 out of 16 pixels, therefore we need to have at least 30 bytes, not 16. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago

Martin Storsjö	9fb0de86b4	pcx: Consume the whole packet if giving up due to missing palette Previously, we returned 0, meaning successful decoding but 0 bytes consumed, leading to an infinite loop.

Martin Storsjö	a81cad8f86	pngdec: Stop trying to decode once inflate returns Z_STREAM_END If the input buffer contains more data after the deflate stream, the loop previously left running infinitely, with inflate returning Z_STREAM_END.

Martin Storsjö	59480abce7	alac: Do bounds checking of lpc_order read from the bitstream In lpc_prediction(), we write up to array element 'lpc_order' in an array allocated to hold 'max_samples_per_frame' elements.

Michael Niedermayer	7859e89ff0	avcodec/tiff_common: add ff_tadd_bytes_metadata() The le argument is passed so the function has the same prototype as the other similar functions. It is otherwise unused Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Ronald S. Bultje	face578d56	Rewrite emu_edge functions to have separate src/dst_stride arguments. This allows supporting files for which the image stride is smaller than the max. block size + number of subpel mc taps, e.g. a 64x64 VP9 file or a 16x16 VP8 file with -fflags +emu_edge.	11 years ago
