Ronald S. Bultje	0399fe0fd2	lzw: fix potential integer overflow.	13 years ago
Ronald S. Bultje	b7b1509d06	truemotion: forbid invalid VLC bitsizes and token values. SHOW_UBITS() is only defined up to n_bits is 25, therefore forbid values larger than this in get_vlc2() (max_bits). tokens[][] can be used as an index in deltas[], which has a size of 64, so ensure the values are smaller than that. This prevents crashes on corrupt bitstreams. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Ronald S. Bultje	bf39d3b59d	truemotion2: handle out-of-frame motion vectors through edge extension. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Kostya Shishkov	a05c41acd1	mp3dec: perform I/S and M/S only when frame mode is joint stereo. Looks like some LAME versions produce dual stereo mode MP3s with flags for intensity and middle stereo set. In this mode those flags should be ignored like the reference decoder and derived ones do.	13 years ago
Carl Eugen Hoyos	282ec7289d	Do not try to use lowres for unusual jpg subsampling. Fixes ticket #1144.	13 years ago
Carl Eugen Hoyos	9a0f2b7b3a	Revert "Fix compilation with hardcoded tables." This reverts commit `b17b296369`.	13 years ago

Ronald S. Bultje	ddcf67c8a5	lzw: prevent buffer overreads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago
Mashiat Sarker Shakkhar	28e8c4d59a	WMAL: Remove inaccurate and unnecessary doxy A call to decode_packet() does not always decode a complete WMA packet. Moreover, this is not the correct place to document calls that are part of the public API. Signed-off-by: Diego Biurrun <diego@biurrun.de>	13 years ago

Michael Bradshaw	b678dd9690	Fixes ticket 1127. I'm still looking into why bpp is getting set to 0.	13 years ago
Ronald S. Bultje	bd508d435b	truemotion2: convert packet header reading to bytestream2. Also use correct buffer sizes in calls to tm2_read_stream(). Together, this prevents overreads. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Diego Biurrun	c0b34e6148	dvdec: drop unnecessary dv_tablegen.h #include dvdec.c uses nothing from dv_tablegen.h. As a welcome side-effect, this fixes compilation of that file with hardcoded tables enabled.	13 years ago

Anton Khirnov	3c6607eb6f	avcodec_encode_{audio,video}: only reallocate output packet when it has non-zero size. Otherwise realloc would free it, which would result in double free later.	13 years ago
