| * movenc: Add an option for enabling negative CTS offsetsMartin Storsjö2017-05-152-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | This reduces the need for an edit list; streams that start with e.g. dts=-1, pts=0 can be encoded as dts=0, pts=0 (which is valid in mov/mp4) by shifting the dts values of all packets forward. This avoids the need for edit lists for such streams (while they still are needed for audio streams with encoder delay). This eases conformance with the DASH-IF interoperability guidelines.

| * arm: Avoid using .dn register aliasesMartin Storsjö2017-05-153-25/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | When targeting windows, the .arch directive isn't available. So far, when building for windows, we've always used gas-preprocessor, both when using msvc's armasm and when using clang. Lately, clang/llvm has implemented the last missing piece (altmacro support) for building our assembly without gas-preprocessor. This means that we now build for arm/windows with clang without any extra compatibility layer. Signed-off-by: Martin Storsjö <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * vf_hwmap: Add reverse mapping for hardware framesMark Thompson2017-04-301-7/+61
| | | | | | | | | | | | | | | | | | This is something of a hack. It allocates a new hwframe context for the target format, then maps it back to the source link and overwrites the input link hw_frames_ctx so that the previous filter will receive the frames we want from ff_get_video_buffer(). It may fail if the previous filter imposes any additional constraints on the frames it wants to use as output.
