Justin Ruggles	27360ccc5e	adx: add an ADX parser. This simplifies the decoder so it doesn't have to process an in-packet header or handle arbitrary-sized packets. It also fixes decoding of files with large headers.	13 years ago
Justin Ruggles	d8cec2d7fc	adx: move header decoding to ADX common code	13 years ago
Justin Ruggles	7ff55d9bdb	adx: calculate the number of blocks in a packet	13 years ago
Justin Ruggles	05c1f11b56	adx: define and use 2 new macro constants BLOCK_SIZE and BLOCK_SAMPLES	13 years ago
Justin Ruggles	d1745619db	adx: check for unsupported ADX formats	13 years ago
Justin Ruggles	994238536a	adx: simplify encoding by using put_sbits()	13 years ago
Justin Ruggles	b237248e29	adx: calculate correct LPC coeffs Instead of using fixed coefficients, the correct way is to calculate the coefficients using the highpass cutoff frequency from the ADX stream header and the sample rate.	13 years ago
Justin Ruggles	954d94dd5e	adx: use 12-bit coefficients instead of 14-bit to avoid integer overflow	13 years ago

Justin Ruggles	ca9e4727ba	adx: fix the data offset parsing in adx_decode_header() first 2 bytes are 0x80, 0x00. offset is only 16-bit. this is according to format descriptions on multimedia wiki and wikipedia.	13 years ago

Mans Rullgard	f7f892e4d5	svq1enc: fix signed multiplication overflow This multiplication can overflow the signed range but not the unsigned. After right-shifting it will thus fit in the signed range again. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	e4faa31a0a	svq1dec: use sign_extend() Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Mans Rullgard	b7581b5c83	cook: use a table for xor key rotation This is simpler and avoids an invalid shift by 32 in the aligned case. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	644bff6c9b	apedec: fix signed integer overflows This bit manipulation is equivalent but avoids undefined shifts and overflows. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago

Reimar Döffinger	7fb55e0b02	rtjpeg: simplify get_block() by using get_bits_left. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Reimar Döffinger	7a62ddb689	rtjpeg: check get_block return value for error. This avoids crashes due to reading out-of-bounds. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Reimar Döffinger	f6afacdb3b	nuv: check per-frame header for validity. Since it contains dimensions parsing an invalid one has rather annoying effects. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago
Reimar Döffinger	785baa738a	nuv: use FFALIGN. Signed-off-by: Anton Khirnov <anton@khirnov.net>	13 years ago

Anton Khirnov	488eec1044	lavc: update doxy to use nondeprecated API.	13 years ago
Martin Storsjö	f32dfad9dc	swscale: Readd #define _SVID_SOURCE This was removed erroneously in `046f081b46`. This define still is necessary for getting MAP_ANONYMOUS defined on linux/glibc, despite the define reshuffling done in that commit. Without MAP_ANONYMOUS defined, the mprotect calls for setting the generated mmx2 scaler code pages executable are left out, causing crashes if that codepath is chosen. This patch fixes scaling from 192x144 to 320x240 with -sws_flags fast_bilinear, which crashes on linux at the moment. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	019dd23657	Fix av_get_channel_layout_string() for positions >31 A value shifted left by >31 needs to have a 64-bit type. As there are no defined channels in this range, the fix is purely theoretical at this point, although it does avoid some invalid shifts triggering the overflow checker. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Rafaël Carré	be1e872582	configure: Store vda lib flags in extralibs instead of ldflags This way the needed linking flags end up in libavcodec.pc. Signed-off-by: Martin Storsjö <martin@martin.st>	13 years ago
Mans Rullgard	cc276c85d1	Make channel layout masks unsigned It makes more sense for a bit mask to use an unsigned type. The change should be source and binary compatible on all supported systems, hence micro version bump. Fixes a few invalid shifts. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	00a856e3f9	dca: ARMv6 optimised decode_blockcode() This is a hand-tuned version of the code with impossible parts of the FASTDIV function ommitted. 2-5% faster overall on Cortex-A8. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Luca Barbato	035af998ad	nullenc: drop AVFMT_RAWPICTURE from the flags This makes the two pass encoding with x264 working with -f null - as first pass.	13 years ago
Janne Grunau	117e2a30f2	frame-mt: return consumed packet size in ff_thread_decode_frame This is required to fulfill avcodec_decode_video2() promise to return the number of consumed bytes on success.	13 years ago
Janne Grunau	d14d4d982c	aacdec: add more fate tests covering SBR and PS Add all seven test bitstreams of Coding Technologies "aacPlus Decoder Check Package". The streams cover different ways to signal SBR and PS in different formats.	13 years ago
Mans Rullgard	6b34fbba9b	MK(BE)TAG: avoid undefined shifts Casting the left-most byte to unsigned avoids an undefined result of the shift by 24 if bit 7 is set. This affects the rm demuxer. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Luca Barbato	7f1b427018	snow: split snow in snowdec and snowenc The common non inlined code goes in snow.c, the common inlined code in snow.h, tables move in snowdata.h (included only by snow.c)	13 years ago
Anton Khirnov	8b7412fe4e	tiffenc: deprecate using compression_level	13 years ago
Ronald S. Bultje	f7f1835258	swscale: fix failing fate tests. isGray() is left as a FIXME for later.	13 years ago
