* aacdec: Reduce the size of buf_mdct.Young Han Lee2011-02-222-9/+12
| | | | | | It was doubled in size for the LTP implementation. This brings it back down to its original size. (cherry picked from commit e22910b21a6c78b0159f98426b10c204f12bc15a)
* vp8: ppc: fix invalid reads in altivec epel mcMans Rullgard2011-02-221-7/+14
| | | | | | | | The 4-tap filters should only access one row/column before the reference block. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit e0e46cae377347cbe1cd27c0d85568921b12c2ad)
* ppc: fix vc1 inverse transform, unbreak buildMans Rullgard2011-02-221-17/+17
| | | | | | | | | 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> (cherry picked from commit 381efba0ecedd41575f99ba9e9bd3826551079f6)
* targa: prevent integer overflow in bufsize check.Ronald S. Bultje2011-02-221-1/+1
| | | | (cherry picked from commit 78e2380a6d09e7a8b2a74d090abfb0a922e046f6)
* VC1: merge idct8x8, coeff adjustments and put_pixels.Ronald S. Bultje2011-02-225-40/+170
| | | | | | Merging these functions allows merging some loops, which makes the results (particularly after SIMD optimizations) much faster. (cherry picked from commit f8bed30d8b176fa030f6737765338bb4a2bcabc9)
* dsputil: make {add/put/put_signed}_pixels_clamped() non-static.Ronald S. Bultje2011-02-222-14/+18
| | | | (cherry picked from commit 484a337cd7cd8bb180c4a1bd3321881f1c874a92)
* VC1: inline vc1_put_block() in vc1_decode_i_blocks().Ronald S. Bultje2011-02-221-35/+13
| | | | | | | 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. (cherry picked from commit bbfd2e7ab4e2ae0b934657fe51afdbbbaead52b7)
* amrnb: use correct size when copying lsf_r arrayMans Rullgard2011-02-221-1/+1
| | | | | | | lsf_r is an array of int16_t, not float. Signed-off-by: Mans Rullgard <mans@mansr.com> (cherry picked from commit 1efa772e20be5869817b2370a557bb14e7ce2fff)
* VC1: don't use vc1_put_block() in vc1_decode_i_blocks_adv().Ronald S. Bultje2011-02-201-3/+11
| | | | | | | | | 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(). (cherry picked from commit 70aa916e4630bcec14439a2d703074b6d4c890a8)
* dsputil_mmx.c: remove ff_vector128.Ronald S. Bultje2011-02-201-4/+1
| | | | | Remove ff_vector128, it is identical to ff_pb_80. (cherry picked from commit bf6fa732459399fac215bdfa44dd39a6fb1d1e01)
* Fix invalid reads in VC1 decoderReimar Döffinger2011-02-201-1/+1
| | | | | Patch discussed and taken from https://roundup.ffmpeg.org/issue2584 (cherry picked from commit 2bbec1eda46d907605772a8b6e8263caa4bc4c82)
* Fix VP3 edge emulationDavid Conrad2011-02-201-2/+1
| | | | | | | 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. (cherry picked from commit a89f4ca005efa5ee82089583c7b8bc00bcee816a)
* aacdec: dsputilize the scalar multiplication in intensity stereoYoung Han Lee2011-02-201-5/+7
| | | | (cherry picked from commit 9707f84fa73c23352937fc7e4e0a85eaf3135cbc)
* VP3: fix decoding of videos with stride > 2048Jason Garrett-Glaser2011-02-201-14/+6
| | | | | | Also remove qscale_table code; this didn't make sense anyways as VP3 doesn't use an MPEG-like quantizer scale. (cherry picked from commit 902685b8abf4e2089802528a32a50f3c68033fda)

* VP8: init one less near_mvJason Garrett-Glaser2011-02-181-1/+0
| | | | | This one didn't actually need to be initialized. (cherry picked from commit 891b1f15a7e45a2a5f91cb4c27d11259ef8e012f)

| | | | | 3*n4 was already calculated in n3. (cherry picked from commit 979395bbbb9381b522b44c3448c24aef9c819ffc)
* ac3enc: fix bug in stereo rematrixing decision.Justin Ruggles2011-02-181-2/+1
| | | | | | | | 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> (cherry picked from commit 5b54d4b376fbd2c291b8a6dba7d425e28f654bcf)

* ac3enc: change default floor code to 7.Justin Ruggles2011-02-161-1/+1
| | | | | | | | 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> (cherry picked from commit 50d7140441b61809ad4ba4ea7b4ad8fe77bc6888)

* Pass VBV delay to the calling application via ctxChristophe Massiot2011-02-162-1/+10
| | | | | | | | | 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.
