Michael Niedermayer	adfdcf87b1	vble: use dsp.add_hfyu_median_prediction() this allows asm optimizations to be used. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Michael Niedermayer	317ea97bff	vble: remove flags copy, its not used in any speed relevant code. Signed-off-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Derek Buitenhuis	e46abbcf77	vble: merge len and val arrays There's no reason to use two arrays for this. Based off commit `2fea60c600` to FFmpeg by Michael Niedermayer. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago

Janne Grunau	bb8a6e03cc	rv40: move loop filter to rv34dsp context Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Aneesh Dogra	464ccb0144	indeo3: check per-plane data buffer against input buffer bounds. Fixes : http://bugzilla.libav.org/show_bug.cgi?id=102 Signed-off-by: Alex Converse <alex.converse@gmail.com>	13 years ago
Aaron Colwell	39a7a5b8ab	pthread: don't increment index on zero-sized packets. The next call to decode() will update from an invalid index, which will either lead to a memcpy() where dest==src (2 threads), or lead to a crash (>2 threads). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Alex Converse	a27805189b	txd: Fix order of operations.	13 years ago

Luca Barbato	1f948745c3	vc1: use an enum for Frame Coding Mode Document it a little and possibly fix a bug in dxva2_vc1.	13 years ago
Aneesh Dogra	97980db487	indeo3: error out if no motion vector is set. This fixes a crash on a corrupt bitstream (bugzilla #93). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Justin Ruggles	0df5e869cb	mpegaudio: do not use init_static_data() for initializing tables. It is called once for each mpegaudio codec that is registered, which adds significant overhead.	13 years ago
Alex Converse	f11b0e9543	wmavoice: Make format string match variable type.	13 years ago
Kostya Shishkov	498605b4ad	vc1: select interlaced scan table by FCM element Interlaced videos can contain progressive frames too and now wrong scantable is selected for them. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Cheng Sun	3f5aa7dfa6	pthread: track thread existence in a separate variable. This fixes a compile error on mingw32 when using p->thread directly (as if it were a pointer) to track thread existence, because the type is opaque and may be a non-pointer. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	13 years ago
Mans Rullgard	8540dcfd7a	snow: fix integer overflows The way these values are used, they should have an unsigned type. A similar change was made for mpegvideo in `cb66847`. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	0e55edcb57	svq1enc: remove stale altivec-related hack altivec.h is no longer (indirectly) included, so this hack is not needed. Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Mans Rullgard	ff6d9cc558	snow: fix signed overflow in byte to 32-bit replication Signed-off-by: Mans Rullgard <mans@mansr.com>	13 years ago
Justin Ruggles	9d2dd356c2	adx: rename ff_adx_decode_header() to avpriv_adx_decode_header() It is used by the ADX decoder, and therefore needs to be exported in order to work with shared libs.	13 years ago
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	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

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
