Michael Niedermayer	3305acdc92	avcodec/indeo3: use signed variables to avoid underflow Fixes out of array read Fixes: signal_sigsegv_1b0a4da_1865_cov_2167818389_computer_anger.avi Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Vittorio Giovara	c6d7c201df	indeo3: check ff_set_dimensions return value CC: libav-stable@libav.org Bug-Id: CID 1135740	10 years ago
Reimar Döffinger	d9e2aceb7f	Add missing "const" all over the place. Only "./configure --enable-gpl" on x86 was tested. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	10 years ago
Michael Niedermayer	81ed7efbe2	avcodec/indeo3: check the return code of ff_set_dimensions() This is currently redundant as the checks before it are tighter than the checks in ff_set_dimensions() but its more robust not to depend on that. Fixes CID1135740 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	11 years ago
Anton Khirnov	317d6a1503	indeo3: stop using deprecated avcodec_set_dimensions	11 years ago

Paul B Mahol	84343dd9d3	indeo3: check return values of av_malloc() Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
Janne Grunau	94235f2ba2	indeo3: avoid writes without necessary alignment in copy_cell() Cells starting at a position aligned to 8 pixels but wider than 4 blocks are copied with 3 blocks per loop. This creates problems on the next loop iterations since the routine copying 2 blocks requires the same alignment on some architectures like ARM NEON.	12 years ago
Anton Khirnov	a97d8cc16e	indeo3: use unaligned reads on reference blocks. They are not guaranteed to be aligned. Fixes Bug 503. CC:libav-stable@libav.org	12 years ago
Anton Khirnov	bda9e6d923	indeo3: use put_pixels instead of put_no_rnd_pixels in copy_cell() They are the same in this case, except put_pixels also has blocksizes smaller than 8.	12 years ago
Anton Khirnov	95220be1fa	indeo3: fix off by one in MV validity check CC:libav-stable@libav.org	12 years ago
Ronald S. Bultje	8f992dc8c7	indeo3: Use hpeldsp instead of dsputil for half-pel functions This makes the Indeo 3 decoder independent of dsputil. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Anton Khirnov	a0a872d073	indeo3: check motion vectors. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago
Anton Khirnov	34e6af9e20	indeo3: fix data size check The data offsets are relative to the bistream header, which is 16 bytes after the start of the data. Fixes invalid reads with corrupted files. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago
Anton Khirnov	66531d634e	indeo3: switch parsing the header to bytestream2 Also add an additional sanity check to the alt_quant table. Fixes invalid reads with corrupted files. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC:libav-stable@libav.org	12 years ago

Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago
Paul B Mahol	b0428741c6	indeo3: move get_buffer() above decode_plane() calls This ensure that decode_plane() mmx code like AV_COPY64() does not interfere with possible float instructions in release_buffer/get_buffer.

Paul B Mahol	b02116cc4a	Revert "Partly revert f174fba: indeo3 decoder does not support direct rendering." `f174fba` did not introduce DR1 flag it was already available before that. This reverts commit `8bf44d5c96`.	12 years ago

Anton Khirnov	f174fbac3c	lavc: add CODEC_CAP_DR1 to all video decoders missing them	12 years ago
Kostya Shishkov	169514c440	indeo3: do not try to output more lines than we can fit Internally chroma planes have multiple of four height while allocated image planes might be smaller if CODEC_FLAG_EMU_EDGE is set. Thus we should not output more lines of chroma than frame can accept. Also the decoder can be safely switched to direct rendering now.	12 years ago
