| | | | | | | | | | | | | | HEVCSEIPictureHash should store only the information extracted from the bitstream and exported to the higher layer (the decoder or the parser). The MD5 context is allocated, used and freed by this higher layer, so it makes more sense for it to also be stored there.

| * arm: Avoid using .dn register aliasesMartin Storsjö2017-05-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | clang now (in the upcoming 5.0 version) is capable of building our arm assembly without relying on gas-preprocessor, although clang/LLVM doesn't support .dn register aliases. The VC1 MC assembly was only built and used if the chosen assembler supported the .dn directives though. This was supported as long as gas-preprocessor was used. This means that VC1 decoding got a speed regression on clang 5.0, unless the user manually chose using gas-preprocessor again. By avoiding using the .dn register aliases, we can build the VC1 MC assembly with the latest clang version. Support for the .dn/.qn directives in clang/LLVM isn't actively planned, see https://bugs.llvm.org/show_bug.cgi?id=18199. This partially reverts 896a5bff64264f4d01ed98eacc97a67260c1e17e.

| * aacsbr: Turnoff in the event of over read.Alex Converse2017-05-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Aliased compressed AAC bytes are almost certainly not meaningful SBR data. In the wild this causes harsh artifacts switching HE-AAC streams that don't have SBR headers aligned with segment boundaries. Turning off SBR falls back to a default set of upsampling parameters that can function as a sort of error concealment. This is consistent with how the decoder handles other sorts of errors.
