Justin Ruggles	a17c3c7d15	avformat: add CRI ADX format demuxer	13 years ago
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	c52ddc6024	adx: simplify adx_decode() by using get_sbits() to read residual samples	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
Justin Ruggles	837bbd19eb	adx: remove unneeded post-decode channel interleaving instead interleave channels while decoding	13 years ago
Justin Ruggles	e2d1eace00	adx: validate header values	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

Cheng Sun	e524eadbf8	[PATCH] Fix crash when initializing multi-threaded decoding for corrupted file. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.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
Mans Rullgard	93c286e54f	qtrle: simplify 32-bit decode using intreadwrite macros Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	3bd1162a52	gif: fix invalid signed shifts 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
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
