Justin Ruggles	d21be5f15b	cosmetics: rename ff_fmt_convert_init_ppc() to ff_fmt_convert_init_altivec(). It only has Altivec functions and is not compiled if Altivec is disabled.	14 years ago
Carl Eugen Hoyos	159683ddec	Fix compilation on powerpc with --disable-altivec.	14 years ago
Sean McGovern	02dd3666c2	h264_mp3toannexb_bsg: don't crash, but warn, if PPS/SPS not found. Should an AVC-1 in MP4 stream not contain SPS or PPS NAL units, this BSF is then unable to allocate an output buffer for the modified stream. Warn that the resulting stream may be unplayable. Fix roundup issue #2386. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Justin Ruggles	53e35fd340	ac3enc: add num_rematrixing_bands to AC3EncodeContext and use it instead of the hardcoded value. Currently it is always 4, but this change will allow it to be adjusted when bandwidth-related features are added such as channel coupling, enhanced channel coupling, and spectral extension.	14 years ago
Justin Ruggles	b35743ffb4	ac3: define AC3_MAX_CPL_BANDS and use it in ac3dec.h	14 years ago
Ronald S. Bultje	8cf9a09d40	vp3-mt: fix deadlock when first frame is not a keyframe.	14 years ago
Mans Rullgard	ff1efc524c	threads: allow thread count of zero This moves setting the thread count to a minimum of 1 to frame_thread_init(), allowing a value of zero to propagate through to the codec if frame threading is not used. This makes auto-threads work in libx264. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago

Alexander Strange	76d8846c4e	huffyuv: Add multithreading support Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Alexander Strange	ad9791e12b	pthreads: Fix bug introduced with thread_safe_callbacks For intra codecs, ff_thread_finish_setup() is called before decoding starts automatically. However, get_buffer can only be used before it's called, so adding this requirement broke frame threading for them. Fixed by moving the call until after get_buffer is finished.

Mans Rullgard	0b32da90f8	ARM: VP8: fix build on systems with global symbol prefix Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Mans Rullgard	8b454c352f	ARM: fix vp8 neon with pic enabled The assembler emits literal pools too far from the load instructions, so we must do it explicitly at a suitable location. Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
Peter Ross	e211e255aa	bink: prevent overflows within binkidct by using int-sized intermediate array Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Peter Ross	a304def1dc	binkaudio: remove unnecessary loop decode_init sets bands[0] == 2, so this loop always sets the band table index (k) to zero. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Peter Ross	582ac86d19	binkaudio: perform band table scaling in decode_init Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Kyle	04973f8082	dxva2: define required feature selection macros Signed-off-by: Mans Rullgard <mans@mansr.com>	14 years ago
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	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	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

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
