Anssi Hannula	7e06e0ede3	dca: use EXT_AUDIO_ID field to determine core extensions This avoids the core substream extensions scan when the EXT_AUDIO_ID field indicates no extensions or only unsupported extensions. The scan is done only if the value of EXT_AUDIO_ID is unknown or indicates a present XCh extension which we can decode. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Justin Ruggles	1108f8998c	vmdaudio: output 8-bit audio as AV_SAMPLE_FMT_U8. There is no need to expand to 16-bits. Just use memcpy() to copy the raw data. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	2ec7862db8	vmdaudio: remove unnecessary fields from VmdAudioContext and use the corresponding AVCodecContext fields instead. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	1e86d685e0	vmdaudio: add out_bps to VmdAudioContext and use it to replace hard-coded sample size. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	1574eff3d2	vmdaudio: simplify vmdaudio_decode_frame() by handling block_type first, then making a single call to vmdaudio_loadsound(). This also adds output buffer size checks for AUDIO and SILENCE block types. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	ba9516cca8	cosmetics: reindent after previous commit Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Justin Ruggles	2d213695fc	vmdaudio: simplify buffer pointer and header size handling. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	7a4fb3fd93	vmdaudio: set *data_size to zero when skipping small packets and add a warning log message. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	22f893e1c9	vmdaudio: validate block type Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	dd1af5136f	vmdaudio: use macros and a local variable for block type. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	6989cb2dae	vmdaudio: correct the silent chunk count in the first block. This fixes A/V sync with several samples, notably: http://samples.mplayerhq.hu/game-formats/sierra-vmd/swat_*.vmd Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	9b73f78600	vmdaudio: output audio samples for standalone silent blocks. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	1328d43313	vmdaudio: remove duplicated code by merging mono and stereo decoding. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	a58bcb40b1	vmdaudio: fix raw_block_size calculation. The size should depend on the output sample size, not the internal bit depth. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Young Han Lee	e22910b21a	aacdec: Reduce the size of buf_mdct. It was doubled in size for the LTP implementation. This brings it back down to its original size.	14 years ago
Mans Rullgard	e0e46cae37	vp8: ppc: fix invalid reads in altivec epel mc The 4-tap filters should only access one row/column before the reference block. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	381efba0ec	ppc: fix vc1 inverse transform, unbreak build GCC 4.3 and later are more particular about signedness matching in vector operations. The operations under if(rangered) were missing assignments and thus had no effect. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	78e2380a6d	targa: prevent integer overflow in bufsize check.	14 years ago
Ronald S. Bultje	f8bed30d8b	VC1: merge idct8x8, coeff adjustments and put_pixels. Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster.	14 years ago
Ronald S. Bultje	484a337cd7	dsputil: make {add/put/put_signed}_pixels_clamped() non-static.	14 years ago
Ronald S. Bultje	bbfd2e7ab4	VC1: inline vc1_put_block() in vc1_decode_i_blocks(). Advantage is that it allows us to combine several loops into a single one, and these can eventually be merged into the IDCT itself. Also, it allows us to remove vc1_put_block(), and makes CODEC_FLAG_GRAY faster.	14 years ago
Mans Rullgard	1efa772e20	amrnb: use correct size when copying lsf_r array lsf_r is an array of int16_t, not float. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Ronald S. Bultje	70aa916e46	VC1: don't use vc1_put_block() in vc1_decode_i_blocks_adv(). Advanced profile never uses "range reduction", so vc1_put_block() quite literally just calls put_pixels_clamped() from vc1_decode_i_blocks_adv(). By inlining the function, we can prevent calling IDCT8x8 if CODEC_FLAG_GRAY is set, and we don't have to scale the coeffs in the [0,256] range, but can instead use put_signed_pixels_clamped().	14 years ago
Ronald S. Bultje	bf6fa73245	dsputil_mmx.c: remove ff_vector128. Remove ff_vector128, it is identical to ff_pb_80.	14 years ago
Reimar Döffinger	2bbec1eda4	Fix invalid reads in VC1 decoder Patch discussed and taken from https://roundup.ffmpeg.org/issue2584	14 years ago
David Conrad	a89f4ca005	Fix VP3 edge emulation With negative stride, the start of the edge_emu buffer should be pointing to the last line, not the end of the buffer. With positive stride, pointing to the end of the buffer was completely wrong.	14 years ago
Young Han Lee	9707f84fa7	aacdec: dsputilize the scalar multiplication in intensity stereo	14 years ago
Jason Garrett-Glaser	902685b8ab	VP3: fix decoding of videos with stride > 2048 Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't use an MPEG-like quantizer scale.	14 years ago

Young Han Lee	979395bbbb	mdct: remove unnecessary multiplication 3*n4 was already calculated in n3.	14 years ago
Justin Ruggles	5b54d4b376	ac3enc: fix bug in stereo rematrixing decision. The rematrixing strategy reuse flags are not reset between frames, so they need to be initialized for all blocks, not just block 0. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Carl Eugen Hoyos	2e3c56a29f	Set maximum lowres value for the MJPEG decoder to 3. While 4 works for some samples, 3 is the correct value since 8x8 DCT is used by (m)jpeg. Signed-off-by: Janne Grunau <janne-ffmpeg@jannau.net>	14 years ago
Justin Ruggles	1f004fc512	ac3dsp: Change punpckhqdq to movhlps in ac3_max_msb_abs_int16(). Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Justin Ruggles	50d7140441	ac3enc: change default floor code to 7. This is to match the value in every (E-)AC-3 file from commercial sources. It has a negligible effect on audio quality. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Reinhard Tartler	737eb5976f	Merge libavcore into libavutil It is pretty hopeless that other considerable projects will adopt libavutil alone in other projects. Projects that need small footprint are better off with more specialized libraries such as gnulib or rather just copy the necessary parts that they need. With this in mind, nobody is helped by having libavutil and libavcore split. In order to ease maintenance inside and around FFmpeg and to reduce confusion where to put common code, avcore's functionality is merged (back) to avutil.

Christophe Massiot	55bad0c602	Pass VBV delay to the calling application via ctx VBV delay is useful for T-STD compliance in some TS muxers. It is certainly possible to retrieve it by parsing the output of FFmpeg, but getting it from the context makes it simpler and less error-prone. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
