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	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	b6ae086682	dv: simplify bitstream splicing in dv_decode_ac() This is simpler and fixes some overflow checker warnings. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	b02aa3a8ea	s3tc: fix shift overflow by using unsigned constant Signed-off-by: Mans Rullgard <mans@mansr.com>	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

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
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
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
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	db431f7efe	h264: add support for decoding planar RGB images.	13 years ago
Justin Ruggles	c1848c4b26	pcmdec: remove unneeded resetting of samples pointer	13 years ago
Anton Khirnov	3eedd29bd7	bethsoftvideo: return proper consumed size for palette packets. Also check for sufficient packet size.	13 years ago
Anton Khirnov	a94c769dad	tiffenc: add a private option for selecting compression algorithm	13 years ago
Mans Rullgard	3a0b72dee0	ARM: remove needless .text/.align directives The 'function' macro already includes the appropriate directives. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Alex Converse	963f685535	aacdec: Fix PS in ADTS. Fixes File1.aac and Bug 80.	13 years ago
Justin Ruggles	0e8fdd41c2	dsputil: use cpuflags in x86 emu_edge_core avoids passing around the extra argument among all the macros it uses	13 years ago
Justin Ruggles	395f2e70dd	dsputil: use movups instead of movdqu in ff_emu_edge_core_sse() This allows emulated_edge_mc_sse() and gmc_sse() to be used under AV_CPU_FLAG_SSE.	13 years ago
Justin Ruggles	05d1e45d1f	wma: initialize prev_block_len_bits, next_block_len_bits, and block_len_bits. The initial values are not checked against the number of block sizes. Initializing them to frame_len_bits will result in a block size index of 0 in these cases instead of something that might be out-of-range. Fixes Bug 81.	13 years ago
Mans Rullgard	85770d6e56	Add libavutil/mathematics.h #includes for INFINITY This fixes build errors in some environments. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Luca Barbato	e97e5a2e02	doxy: introduce an empty structure in libavcodec	13 years ago
Mans Rullgard	8ee2b4672f	ARM: add explicit .arch and .fpu directives to asm.S This prevents build errors when compiler and assembler default targets differ. Ideally each file would declare the highest level it requires. This is however not easily possible as it complicates assembling pre-armv6t2 code in Thumb-2 mode. HAVE_NEON is used as indicator for ARMv7-A since no other symbol exists for this and NEON is only available in this variant. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Janne Grunau	0945eddec0	pthread: do not touch has_b_frames Adding the thread count in frame level multithreading to has_b_frames as an additional delay causes more problems than it solves. For example inconsistent behaviour during timestamp calculation in libavformat. Thread count and frame level multithreading are both set by the user. If the additional delay caused by frame level multithreading needs to be considered in the calling code it has all information to take it into account. Should it become necessary to calculate a maximum delay inside libavcodec it should be exported as its own field and not reusing an existing field. Based on a patch by Michael Niedermayer.

Justin Ruggles	a8fe9a7242	pthread: add some malloc failure checks	13 years ago
Justin Ruggles	f3a29b750a	avcodec: move some AVCodecContext fields to an internal struct. A new field, AVCodecContext.internal is used to hold a new struct AVCodecInternal, which has private fields that are not codec-specific and are used by general libavcodec functions. Moved internal_buffer, internal_buffer_count, and is_copy.	13 years ago
