Martin Storsjö	a711a2cb47	mpegvideo: Avoid 32-bit wrapping of linesize multiplications This makes sure that linesize * start_y doesn't overflow, so that emulated_edge_mc can get back the original value if needed.

Michael Niedermayer	8088d6f5f1	avcodec/pictordec: run av_image_check_size() unconditionally This ensures that no invalid size leaks through (This issue is hypothetical, ive no testcase) Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Martin Storsjö	35cbc98b72	alac: Check that the channels fit at the given offset The code tries to decode a number of channels at the offset given by the ff_alac_channel_layout_offsets table. Even if the number of channels decoded so far doesn't exceed the total number of channels, we need to check that we actually can decode that number of channels at this offset as well.

Martin Storsjö	f7c5883126	alac: Limit max_samples_per_frame Otherwise buffer size calculations in allocate_buffers could overflow later, making the code think a large enough buffer actually was allocated.

Anton Khirnov	5f7aecde02	pictordec: break out of both decoding loops when y drops below 0 Otherwise picmemset can get called with negative y, resulting in an invalid write. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	12 years ago

Christian Schmidt	a42e3a6700	pcm_dvd: consolidate pieces from pcm.c and mpeg.c Remove the header decoding for PCM audio from mpeg.c and the 20/24bit parts from pcm.c and merge them into a new decoder in pcm-dvd.c. The decoder has added support for samples that span multiple packets and modified 20/24bit group decoding. Both is needed to decode samples that have been generated with DVD-Lab Pro 2. The decoding of 16bit PCM and two channel 24bit is identical to before. No other samples are known to verify the correctness of the encoding this software does. The complete list of tested formats is 48kHz/16bit/2-8 channels 48kHz/24bit/2-5 channels 96kHz/16bit/2-4 channels 96kHz/24bit/2 channels Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago

Christian Schmidt	0d6549d8b5	pcm_bluray: rename pcm-mpeg.c to pcm-bluray.c The original idea was to collect PCM codecs that could appear in various MPEG streams in this file. Discussion in IRC lead to the conclusion that one codec per file would be better and stop the need for #ifdefs.	12 years ago
