Diego Biurrun	9103185bd1	dsputil: Drop ff_check_alignment() function The function is supposed to confirm that the compiler provided enough alignment, but in practice it is only run in certain code paths and insufficient alignment problems are restricted to legacy compilers.	11 years ago

Diego Biurrun	b4dd424d96	Remove all SPARC architecture optimizations SPARC is no longer being used in any multimedia-related fields and the VIS optimizations only represent a maintenance burden.	11 years ago

Janne Grunau	5a7f382a5d	armv6: vp8: use explicit labels in motion compensation asm The integrated arm assembler in clang-503.0.38 (Xcode-5.1) fails to assemble a branch to 'label + offset' in thumb mode.	11 years ago

Janne Grunau	634d9d8b39	arm: get_cabac inline asm Based on the aarch64 asm. CPU cycle counts on cortex-a9 compared to gcc 4.8.2: before: 475 decicycles in get_cabac_noinline, 67106035 runs, 2829 skips after: 393 decicycles in get_cabac_noinline, 67106474 runs, 2390 skips Overall speedup is above 2%. Code generated by clang 3.4 is slower on the same hardware and the relative change is a little larger.	11 years ago
Janne Grunau	dfe224f377	aarch64: get_cabac inline asm Based on the x86 branchless get_cabac asm. get_cabac_noinline() gets approximately 20% faster (no cycle counts available) compared to clang from Xcode 5.1 beta5. More than 6% faster overall. A part of the overall speedup might be explained by additional inlining of get_cabac().	11 years ago
Janne Grunau	4506a854a4	arm: vp3: remove incorrect const in ff_vp3_idct_dc_add_neon declaration Was missed in `aeaf268e52` when integrating clear_blocks into the idct.	11 years ago
Janne Grunau	61985ad72c	arm: hpeldsp: fix put_pixels8_y2_{,no_rnd_}armv6 The overread avoidance fix in `cbddee1cca` broke the computation for the last row since it prevented the safe reading from the height+1-th row. CC: libav-stable@libav.org	11 years ago

Rainer Hochecker	b66382101c	dxva2: Increase maximum number of slices for mpeg2 Some content requires an higher number of slices in order to render properly. Rise the number to 1024 and warn if ever it exceeds. Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Diego Biurrun	d48430c367	build: Let the SVQ3 decoder depend on the H.264 decoder The SVQ3 decoder reuses large parts of the H.264 decoder so it makes no sense to enable the former but not the latter. Also drop unnecessary h263.o object from SVQ3 decoder object list.	11 years ago
Diego Biurrun	3bfdee00cd	x86: dcadsp: Fix linking with yasm and optimizations disabled Some optimized functions reference optimized symbols, so the functions must be explicitly disabled when those symbols are unavailable.	11 years ago
Janne Grunau	cbddee1cca	arm: hpeldsp: prevent overreads in armv6 asm Based on a patch by Russel King <rmk+libav@arm.linux.org.uk> Bug-Id: 646 CC: libav-stable@libav.org	11 years ago

Vittorio Giovara	973dc4e8d4	put_bits: Remove unused includes This requires adding includes to other files that relied on these being included implicitly.	11 years ago
Vittorio Giovara	5397386eff	mathops: move macro to the only place it is used This helps in disentangling lavf and lavc too.	11 years ago

Anton Khirnov	d1f9563d50	pthread_frame: flush all threads on flush, not just the first one avcodec_flush_buffers() must release all internally held references according to its documentation, for which all the threads need to be flushed. CC:libav-stable@libav.org Bug-Id: vlc/9665	11 years ago
Diego Biurrun	2f02bbcca0	build: Let the ffvhuff decoder/encoder depend on the huffyuv decoder/encoder Almost all of the code is shared so there is little point in enabling one decoder/encoder without the other.	11 years ago
Diego Biurrun	34150be515	build: Let the iac decoder depend on the imc decoder Almost all of the code is shared so there is little point in enabling one decoder without the other.	11 years ago
Diego Biurrun	8e0cf39faf	build: Let all MJPEG-related decoders depend on the MJPEG decoder These codecs compile all of the MJPEG code anyway, so there is little point in not enabling the MJPEG decoder directly. This also simplifies the dependency declarations for the MJPEG codec family.	11 years ago
Diego Biurrun	0a36988e48	build: Let AMV decoder depend on the SP5X decoder This codec compiles all of the SP5X code anyway, so there is little point in not enabling the decoder directly. This also simplifies the dependency declaration for the AMV decoder.	11 years ago

Vittorio Giovara	17a63ff0cd	h264: update flag name in ff_h264_decode_ref_pic_list_reordering() This is the name used in the specifications.	11 years ago

Vittorio Giovara	e70ab7c1f5	h264: add MVCD to the list of High profiles in SPS Also comment all previous profiles.	11 years ago
Hendrik Leppkes	3aca10bf76	latm: Always reconfigure if no extradata was set previously AAC LOAS can have new audio config objects in the stream itself. Make sure the decoder reconfigures itself when the first one arrives midstream. Bug-Id: 644 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	11 years ago
Janne Grunau	6e4009d4cd	arm: dcadsp: implement decode_hf as external NEON asm	11 years ago
Christophe Gisquet	4cb6964244	dcadec: simplify decoding of VQ high frequencies The vector dequantization has a test in a loop preventing effective SIMD implementation. By moving it out of the loop, this loop can be DSPized. Therefore, modify the current DSP implementation. In particular, the DSP implementation no longer has to handle null loop sizes. The decode_hf implementations have following timings: For x86 Arrandale: C SSE SSE2 SSE4 win32: 260 162 119 104 win64: 242 N/A 89 72 The arm NEON optimizations follow in a later patch as external asm. The now unused check for the y modifier in arm inline asm is removed from configure.	11 years ago
