Andreas Cadhalpun	372aa0777a	pngdec: don't use AV_PIX_FMT_MONOBLACK for apng AV_PIX_FMT_MONOBLACK has the AV_PIX_FMT_FLAG_BITSTREAM flag, i.e. linesize can be smaller than width. Since x_offset is only check against the width, this can lead to x_offset * bpp >= image_linesize. In this case ptr could be set to a position outside the image_buf in png_handle_row, leading to memory corruption and thus crashes.

Andreas Cadhalpun	8f760be4d3	pngdec: return correct error code from decode_frame_common During the loop ret can get changed. Since it is not set on all failure paths, decode_frame_common can return 0 even though an error occurred.

Andreas Cadhalpun	287dbb0771	pngdec: check s->last_picture.f->data[0] before using it This check was removed in commit `08aec6f6`, but s->last_picture.f->data[0] is still used in handle_p_frame_apng unconditionally. This fixes a segmentation fault. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago

Ronald S. Bultje	844799b033	vp9: invert order of two conditions. This makes it equal to row-based loopfilter code, and also makes the chroma/luma code identical.	10 years ago

foo86	e80b2b9c81	avcodec/dca_parser: Extend DTS core sync word and fix existing check Check extended sync word for 16-bit LE and BE core streams to reduce probability of alias sync detection. Previously sync word extension was checked only for 14-bit streams (and this check did not properly work across buffer boundary). Use 64-bit parser state to make extended sync word detection work across buffer boundary. This is sufficient to make the sample in ticket #4492 parse successfully.

Anton Khirnov	a0f2946068	h264: use properly allocated AVFrames	10 years ago
Anton Khirnov	7a4f74eed5	h264: embed the DPB in the context It now has a fixed size and is initialized only once, so there is no point in allocating it separately.	10 years ago
Anton Khirnov	88c612e3a4	h264: merge the init and reinit paths in update_thread_context() There is no real need to handle the init case specially, everything necessary is initialized in the reinit code as well.	10 years ago
Anton Khirnov	8a66fd4026	h264: drop the reinit parameter from init_slice_header() It is only used to decide whether to call free_tables(), but that function is safe to call on an uninitialized context as well.	10 years ago
Anton Khirnov	c9ccbc7333	h264: update the current bit depth/chroma type in init_slice_header() With frame threading, it is currently only updated in the context where the change occurs, but not in any other contexts.	10 years ago
Anton Khirnov	29dcde2b87	h264: copy nal_length_size in update_thread_context It does not make sense to copy is_avc without copying this as well. This patch should not change anything for now, but will have an effect in later commits.	10 years ago
Anton Khirnov	440e8dd374	h264: drop a comment that carries no useful information	10 years ago
Anton Khirnov	11f024ef0a	h264: move freeing the escaped RBSP buffer to free_context() It does not logically belong in free_tables(), since it's not allocated in alloc_tables() and its size has nothing to do with the frame size.	10 years ago
Anton Khirnov	ee62b364be	h264: eliminate ff_h264_set_parameter_from_sps() That function currently does two things -- reinitializing the DSP contexts and setting low_delay based on the SPS values. The former more appropriately belongs in h264_slice_header_init(), while the latter only really makes sense in decode_slice_header(). The third call to ff_h264_set_parameter_from_sps(), done immediately after parsing a new SPS, appears to serve no useful purpose, so it is just dropped. Also, drop now unneeded H264Context.cur_chroma_format_idc.	10 years ago
Anton Khirnov	54986d6db9	h264: move context reinit lower down in update_thread_context() It uses some fields from the SPS, which is not yet set where the reinit is called currently.	10 years ago
