* h264: Add support for alternative transfer characterics SEIVittorio Giovara2017-08-10
| | | | | | | | | | The use of this SEI is for backward compatibility in HLG HDR systems: older devices that cannot interpret the "arib-std-b67" transfer will get the compatible transfer (usually bt709 or bt2020) from the VUI, while newer devices that can interpret HDR will read the SEI and use its value instead.

* vaapi_encode: Move quality option to common codeMark Thompson2017-08-06
| | | | | | | | | Use AVCodecContext.compression_level rather than a private option, replacing the H.264-specific quality option (which stays only for compatibility). This now works with the H.265 encoder in the i965 driver, as well as the existing cases with the H.264 encoder.
* hevc: Validate the number of long term reference picturesMark Thompson2017-08-05
| | | | | This would overflow if the stream contained a value greater than the maximum allowed by the standard (32).
* hevc: Improve stream constraint values in common headerMark Thompson2017-08-05
| | | | | | | | Add comments to describe the sources of the constraint values expressed here, and add some more related values which will be used in following patches. Fix the incorrect values for SPS and PPS count (they are not the same as those used for H.264), and remove HEVC_MAX_CU_SIZE because it is not used anywhere.
* h264: Add stream constraint values to the common headerMark Thompson2017-08-05
| | | | With comments describing the derivation of each value.
* mov: move stsd finalization to an appropriate placeSean McGovern2017-07-31
| | | | | | | | | | | mov_finalize_stsd_codec() parses stream information from the ALAC extradata, so run it after the extradata processing is completed in mov_read_stsd(). Fixes playback of 96kHz ALAC streams muxed by qaac or the reference alac encoder. Adapted from an FFmpeg patch by Hendrik Leppkes <h.leppkes@gmail.com> Bug-Id: 1072
* mov: Do not set stsd_count if mov_read_stsd() failsSean McGovern2017-07-31
| | | | Based on an FFmpeg patch by Michael Niedermayer <michael@niedermayer.cc>
* mov: log and return early on non-positive stsd entry countsSean McGovern2017-07-30

* hevcdec: add a CUVID hwaccelAnton Khirnov2017-07-28

* fate/hevc: specify output pixel format explicitlyAnton Khirnov2017-07-28
| | | | This allows running those tests with hwaccel.
* hevcdec: set the active SPS before calling get_format()Anton Khirnov2017-07-28
| | | | This way the SPS is available to the hwaccel init code.

* h264dec: add a CUVID hwaccelAnton Khirnov2017-07-26
| | | | | Some parts of the code are based on a patch by Timo Rothenpieler <timo@rothenpieler.org>
* decode: add a per-frame private data for hwaccel useAnton Khirnov2017-07-26
| | | | | | This will be useful in the CUVID hwaccel. It should also eventually replace current decoder-specific mechanisms used by various other hwaccels.
* decode: add a mechanism for performing delayed processing on the decoded framesAnton Khirnov2017-07-26
| | | | This will be useful in the CUVID hwaccel.
* decode: add a method for attaching lavc-internal data to framesAnton Khirnov2017-07-26
| | | | | | | | Use the AVFrame.opaque_ref field. The original user's opaque_ref is wrapped in the lavc struct and then unwrapped before the frame is returned to the caller. This new struct will be useful in the following commits.
* decode: avoid leaks on failure in ff_get_buffer()Anton Khirnov2017-07-26
| | | | | | | If the get_buffer() call fails, the frame might have some side data already set. Make sure it gets freed. CC: libav-stable@libav.org

* imgutils: add function to clear an image to blackwm42017-07-26
| | | | | | | | | | | | | | | | | | | Black isn't always just memset(ptr, 0, size). Limited YUV in particular requires relatively non-obvious values, and filling a frame with repeating 0 bytes is disallowed in some contexts. With component sizes larger than 8 or packed YUV, this can become relatively complicated. So having a generic function for this seems helpful. In order to handle the complex cases in a generic way without destroying performance, this code attempts to compute a black pixel, and then uses that value to clear the image data quickly by using a function like memset. Common cases like yuv410p10 or rgba can't be handled with a simple memset, so there is some code to fill memory with 2/4/8 byte patterns. For the remaining cases, a generic slow fallback is used.

* build: Add feature test macros for glibc 2.19+Diego Biurrun2017-07-10
| | | | | | | glibc introduced _DEFAULT_SOURCE in version 2.19 to replace _BSD_SOURCE and _SVID_SOURCE, which were deprecated in version 2.20. Add _DEFAULT_SOURCE where the latter two are used to be forwards-compatible and avoid warnings about the use of deprecated definitions.

| | | | | | | | | | Do not use skip_remaining() to fully wipe the cache, as this could do a 64-bit shift of a 64-bit variable which is undefined behavior in C. Instead set the related variables to zero directly. Thanks to Uoti for pointing out the problem. CC: libav-stable@libav.org

* d3d11va: Check WINAPI_FAMILY instead of HAVE_LOADLIBRARYMartin Storsjö2017-07-05
| | | | | | | | | | | | | If using the winstore compat library, a fallback LoadLibrary function does exist, that only calls LoadPackagedLibrary though (which doesn't work for dynamically loading d3d11 DLLs). Therefore explicitly check the targeted API family instead. Make this check a reusable HAVE_* component which other parts of the libraries can check when necessary as well.
