* aarch64: vp8: Move the vp8dsp makefile entries to the right placesMartin Storsjö2019-02-19
| | | | | | | | | | | | Even if NEON would be disabled, the init functions should be built as they are called as long as ARCH_AARCH64 is set. These functions are part of a generic DSP subsytem, not tied directly to one decoder. (They should be built if the vp7 decoder is enabled, even if the vp8 decoder is disabled.)

* aarch64: vp8: Fix assembling with clangMartin Storsjö2019-02-19
| | | | | | | | | | | | | | | | This also partially fixes assembling with MS armasm64 (via gas-preprocessor). The movrel macro invocations need to pass the offset via a separate parameter. Mach-o and COFF relocations don't allow a negative offset to a symbol, which is handled properly if the offset is passed via the parameter. If no offset parameter is given, the macro evaluates to something like "adrp x17, subpel_filters-16+(0)", which older clang versions also fail to parse (the older clang versions only support one single offset term, although it can be a parenthesis.

* libavcodec/zmbvenc: motion estimation improvements/bug fixes:Matthew Fearnley2019-02-19
| | | | | | | | - Clamp ME range to -64..63 (prevents corruption when me_range is too high) - Allow MV's up to *and including* the positive range limit - Allow out-of-edge ME by padding the prev buffer with a border of 0's - Try previous MV before checking the rest (improves speed in some cases) - More robust logic in code - ensure *mx,*my,*xored are updated together
* libavcodec/zmbvenc: block scoring improvements/bug fixesMatthew Fearnley2019-02-19
| | | | | | | | - Improve block choices by counting 0-bytes in the entropy score - Make histogram use uint16_t type, to allow byte counts from 16*16 (current block size) up to 255*255 (maximum allowed 8bpp block size) - Make sure score table is big enough for a full block's worth of bytes - Calculate *xored without using code in inner loop

* avcodec/version: Bump micro-version for nvdec/cuviddec changesPhilip Langdale2019-02-16
| | | | I forgot to add the version bump and changelog within the changes.
* avcodec/cuviddec: Add support for decoding HEVC 4:4:4 contentPhilip Langdale2019-02-16
| | | | | | | | | | | This is the equivalent change for cuviddec after the previous change for nvdec. I made similar changes to the copying routines to handle pixel formats in a more generic way. Note that unlike with nvdec, there is no confusion about the ability of a codec to output 444 formats. This is because the cuvid parser is used, meaning that 444 JPEG content is still indicated as using a 420 output format.
* avcodec/nvdec: Explicitly mark codecs that support 444 output formatsPhilip Langdale2019-02-16
| | | | | | | | | With the introduction of HEVC 444 support, we technically have two codecs that can handle 444 - HEVC and MJPEG. In the case of MJPEG, it can decode, but can only output one of the semi-planar formats. That means we need additional logic to decide whether to use a 444 output format or not.
* avcodec/nvdec: Add support for decoding HEVC 4:4:4 contentPhilip Langdale2019-02-16
| | | | | | | | | | | | | The latest generation video decoder on the Turing chips supports decoding HEVC 4:4:4. Supporting this is relatively straight-forward; we need to account for the different chroma format and pick the right output and sw formats at the right times. There was one bug which was the hard-coded assumption that the first chroma plane would be half-height; I fixed this to use the actual shift value on the plane. We also need to pass the SPS and PPS range extension flags.
* avcodec/hevc_ps: Expose all SPS and PPS range extension flagsPhilip Langdale2019-02-16
| | | | | | | We need all the flags to be exposed to be able to pass them on to HW decoders. I did not attempt to nuance any of the warnings about flags being unsupported as there's no way, at the point we extract flags, to say whether an HW decoder is being used.

* add libaribb24 ARIB STD-B24 caption decoderJan Ekström2019-02-10
| | | | | | | | | | | | | | | | | | | | | | | | * Outputs ASS lines with basic coloring and font scaling for each given region. * Sets the default style to the resolution of the subtitle plane (for example, 960x540 / 36pt font for profile A). * Has options to: * Disable ruby text (which is coded as regions which have half-height text in libaribb24). Enabled by default as without positioning ruby text only confuses as it is usually coded in the beginning of the decoded subtitle line. * Set the working directory, in which libaribb24 will read configuration as well as into which it may save broadcast extra symbols as PNG. Unset by default. The unconventional library check can be explained by the library's current master branch being licensed as LGPLv3, but at the time of writing the latest official release is still licensed under GPLv3. Thus, one either has to wait for the following release, or enable GPLv3.
