* avcodec/prores_ks: Fix luma quantization if q >= MAX_STORED_QAlex Mogurenko2018-12-30
| | | | | | | | | | | | | The problem occurs in slice quant estimation and slice encoding: If the slice quant is larger than MAX_STORED_Q we don't use pre-calculated quant matrices, but generate a new one, but both qmat and qmat_chroma both point to the same table, so the luma table ends up having chroma table values. Add custom_chroma_q the same way as custom_q. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com>

| | | | | | | | | The AV_INPUT_BUFFER_PADDING_SIZE has been increased to 64, but the value is still 32 in function ff_hevc_sao_edge_filter_8_msa. So, use AV_INPUT_BUFFER_PADDING_SIZE directly. Also, use MAX_PB_SIZE directly instead of 64. Fate tests passed. Reviewed-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* cbs_av1: Fix reading of overlong uvlc codesMark Thompson2018-12-22
| | | | | | | | | | | | | | | | The specification allows 2^32-1 to be encoded as any number of zeroes greater than 31, followed by a one. This previously failed because the trace code would overflow the array containing the string representation of the bits if there were more than 63 zeroes. Fix that by splitting the trace output into batches, and at the same time move it out of the default path. (While this seems likely to be a specification error, libaom does support it so we probably should as well.) From a test case by keval shah <skeval65@gmail.com>.

* lavc/qsv_hevc: correct QSV HEVC default plugin on WindowsZhong Li2018-12-18
| | | | | | | | | | | | | | | | | | | | | | | | | | 1. Old logic meaned: everywhere, except Windows, ffmpeg has to use HW acceleration, but on Windows ffmpeg has to use (unavailable) software HEVC by default 2. Software HEVC is available only if you provide corresponding software MediaSDK library, which isn't provided with ffmpeg. More information could be found in https://github.com/Intel-Media-SDK/MediaSDK/blob/master/doc/samples/readme-encode_linux.pdf 3. HW HEVC decoding/encoding are available on Windows in the driver by default Note: Default case should be the most common case but this change still has potential risk on windows if HW path is not supported(or doesn't work as expection). (See the historical disscution: https://lists.libav.org/pipermail/libav-devel/2016-November/080419.html). In such case, two options suggested: 1. Use the option "-load_plugin hevc_sw" to switch SW path manually. 2. Or report bug to Intel windows driver if your GPU can support HEVC HW codec. (HEVC decoding is supported since Braswell, and encoding supported since Skylake) Patch started by Landgraph. Add similar change for hevc decoder and bump a new version.
