Martin Storsjö	e788ca05a7	hevcdec: Use LOCAL_ALIGNED_* for declaring local variables with alignment Not all compilers can do alignment larger than the normal stack alignment for variables on the stack. In these cases, the LOCAL_ALIGNED_* macros produce the workaround alignment wrapper consisting of a padded array and a pointer variable. This fixes the hevc fate tests on RVCT/ARMCC after adding IDCT assembly that actually assumes/relies on this alignment. Signed-off-by: Martin Storsjö <martin@martin.st>	8 years ago

Anton Khirnov	a02ae1c683	hevcdec: export cropping information instead of handling it internally	8 years ago
Steve Lhomme	2835e9a9fd	hevcdec: add P010 support for D3D11VA Given it's the same API than DVXA2 I don't know why the same output was not enabled for both. Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 years ago
Anton Khirnov	ea8b730d8e	hevcdec: add a VAAPI hwaccel Partially based on a patch by Timo Rothenpieler <timo@rothenpieler.org>. Additional scaling list handling fix by Jun Zhao <mypopydev@gmail.com>.	8 years ago
Anton Khirnov	373fd76b4d	hevcdec: do not set decoder-global SPS prematurely It should only be set after the decoder state has been fully initialized for using that SPS. Fixes possible invalid reads on get_format() failure. CC: libav-stable@libav.org	8 years ago
Anton Khirnov	86157e6db2	hevc: decouple calling get_format() from exporting the SPS parameters This makes sure ff_get_format() does not get called unnecessarily from update_thread_context().	8 years ago

Vittorio Giovara	5be2153111	hevc: Move hevc_decode_extradata before frame decoding Avoids a forward-declaration in the following commit. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	8 years ago
Anton Khirnov	59c90097a0	hevc: factor out a repeated condition	8 years ago
Anton Khirnov	0bfdcce4d4	hevc: move the SliceType enum to hevc.h Those values are decoder-independent and are also use by the VA-API encoder.	8 years ago
Anton Khirnov	f6e2f8a9ff	hevcdec: move parameter set parsing into a separate header This code is independent from the decoder, so it makes more sense for it to to have its own header.	8 years ago
Anton Khirnov	150c896a9e	hevcdec: split ff_hevc_diag_scan* declarations into a separate header This will be useful in the following commits.	8 years ago
Anton Khirnov	c359d624d3	hevcdec: move decoder-independent declarations into a separate header This way they can be reused by other code without including the whole decoder-specific hevcdec.h Also, add the HEVC_ prefix to them, since similarly named values exist for H.264 as well and are sometimes used in the same code.	8 years ago
Anton Khirnov	4abe3b049d	hevc: rename hevc.[ch] to hevcdec.[ch] This is more consistent with the rest of libav and frees up the hevc.h name for decoder-independent shared declarations.	8 years ago
Diego Biurrun	ba479f3daa	hevc: Change type of array stride parameters to ptrdiff_t ptrdiff_t is the correct type for array strides and similar.	8 years ago

Philip Langdale	8d34a2f803	vdpau: Support for VDPAU accelerated HEVC decoding Signed-off-by: Rémi Denis-Courmont <remi@remlab.net> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Philip Langdale	8958c5c64d	hevc: Track long and short term RPS size for VDPAU Today, we track the short term RPS size for DXVA, but only if the SliceHeader RPS is being used. Otherwise it's left uninitialized. NVIDIA's VDPAU implementation requires that the size be accurately tracked even if an SPS RPS is being used. In this case, it's really counting the size of the RPS idx information, but you end up with mangled output if the value is not accurate. VDPAU also needs the size of the long term RPS.

Anton Khirnov	2c6811397b	lavc: add profiles to AVCodecDescriptor The profiles are a property of the codec, so it makes sense to export them through AVCodecDescriptors, not just the codec implementations.	9 years ago
Anton Khirnov	e7078e842d	hevcdsp: add x86 SIMD for MC	9 years ago
Anton Khirnov	a853388d2f	hevc: change the stride of the MC buffer to be in bytes instead of elements Currently, the frame stride is passed in bytes, while the MC buffer size is in int16_t elements, This can be confusing, so pass both strides in bytes.	9 years ago
Anton Khirnov	688417399c	hevcdsp: split the pred functions by width This should allow for more efficient SIMD.	9 years ago
Anton Khirnov	818bfe7f0a	hevcdsp: split the epel functions by width This should allow for more efficient SIMD.	9 years ago
Anton Khirnov	1f821750f0	hevcdsp: split the qpel functions by width instead of by the subpixel fraction This should allow for more efficient SIMD. Keep the C versions as they are now, to allow the compiler to inline the interpolation coefficients.	9 years ago
Anton Khirnov	a8956eca1f	cabac: Make CABAC states hardcoded There is not much reason to generate such a small table at runtime. Signed-off-by: Derek Buitenhuis <derekb@vimeo.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago
Vittorio Giovara	b8b13acd70	hevc: Simplify logical check The intended meaning is "if this block is the first block in a slice then its left boundary is a slice boundary". Silence a logical-not-parentheses warning from gcc.	9 years ago
Vittorio Giovara	2268db2cd0	lavu: Drop the {minus,plus}1 suffix from AVComponentDescriptor fields The new fields can be accessed directly and are more intelligible. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago

Anton Khirnov	a062a55d37	hevc_parser: fix standalone build with the hevc decoder disabled The parser depends on hevc_ps, which in turn needs some data tables. Found-by: James Almer <jamrial@gmail.com>	10 years ago
Anton Khirnov	077b559433	hevc: handle a NULL sps in set_sps() properly This can happen in update_thread_context(), when the previous frame was corrupted.	10 years ago
Anton Khirnov	18156b53f9	hevc: do not pass an entire HEVCContext into export_stream_params() It only needs the parameter sets.	10 years ago
Anton Khirnov	7f78155dc6	hevc: improve a comment That loop does the actual full decoding, so 'parse' can be misleading.	10 years ago
Anton Khirnov	d82e1adc20	hevc: move splitting the packet into NALUs into a separate function This function is independent of the decoding context, so we'll be able to use it in the parser.	10 years ago
Anton Khirnov	ae05b48655	hevc: eliminate the second call to hls_nal_unit() Also, make hls_nal_unit() work only on the provided NAL unit, without requiring a whole decoding context. This will allow splitting this code for reuse by the parser.	10 years ago
Anton Khirnov	d7bebe4805	hevc: skip invalid/ignored NALUs when splitting the packet There is no need to wait until actually decoding the NALU. This will allow to get rid of the second hls_nal_unit() call later.	10 years ago
Anton Khirnov	b11acd5732	hevc: remove HEVCContext usage from hevc_ps Factor out the parameter sets into a separate struct and use it instead. This will allow us to reuse this code in the parser.	10 years ago
