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>	9 years ago
Anton Khirnov	d8ebb6157d	hevcdsp: fix a function name put_weighted_pred_avg should be put_unweighted_pred_avg, there is no weighting there.	9 years ago
Anton Khirnov	a1926a29fb	hevc: avoid invalid shifts of negative values	9 years ago
Vittorio Giovara	def97856de	lavc: AV-prefix all codec capabilities Express bitfields more simply. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 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>	9 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.	9 years ago
Anton Khirnov	18156b53f9	hevc: do not pass an entire HEVCContext into export_stream_params() It only needs the parameter sets.	9 years ago
Anton Khirnov	7f78155dc6	hevc: improve a comment That loop does the actual full decoding, so 'parse' can be misleading.	9 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.	9 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.	9 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.	9 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.	9 years ago
Andreas Cadhalpun	9f4c7397a2	hevc: check slice address length It is used as get_bits argument and reading 0 bits doesn't make sense. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Anton Khirnov	69ab9f53f9	hevc: split bitstream unescaping to a separate file It will be useful in the QSV HEVC encoder.	9 years ago
Anton Khirnov	fd124d8357	hevc_ps: split the code for parsing the SPS and exporting it into the context This will be useful in the later commits, where we want to parse an SPS without having a whole decoding context.	9 years ago

Steve Lhomme	d8039ef8d2	D3D11va: add a Direct3D11 video decoder similar to DXVA2 Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	10 years ago
wm4	3efe0393e4	hevc: make avcodec_decode_video2() fail if get_format() fails Personally, I need the decoder to back out if get_format() returns no usable pixel format. This didn't work because the error code was not propagated down the call chain. This in turn happened because the variable declaration removed in this patch shadowed the variable, whose value is returned at the end of the function. Consequently, failures of decode_nal_unit() were ignored in this place.

Anton Khirnov	7693ba0a0e	hevc: export stream parameters from extradata This allows the callers to have a hint of the probable stream parameters without actually decoding anything.	10 years ago
Anton Khirnov	1ae7afd256	hevc: split out setting AVCodecContext parameters Additionally always set the software pixel format, so it's available even if ff_get_format() is not called later. This will be useful for exporting stream parameters from init().	10 years ago
Peter Meerwald	eea769df32	hevc: Use generic av_clip function, not C implementation hevc seems to be the only place where the C implementation of the av_clip function is explicitly selected, precluding platform-specific optimizations Signed-off-by: Peter Meerwald <pmeerw@pmeerw.net> Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago
