      aarch64: vp8: Optimize vp8_idct_add_neon for aarch64 · 7e42d5f0
      Martin Storsjö authored
      
      
      The previous version was a pretty exact translation of the arm
      version. This version does do some unnecessary arithemetic (it does
      more operations on vectors that are only half filled; it does 4
      uaddw and 4 sqxtun instead of 2 of each), but it reduces the overhead
      of packing data together (which could be done for free in the arm
      version).
      
      This gives a decent speedup on Cortex A53, a minor speedup on
      A72 and a very minor slowdown on Cortex A73.
      
      Before:        Cortex A53    A72    A73
      vp8_idct_add_neon:   79.7   67.5   65.0

      aarch64: vp8: Skip saturating in shrn in ff_vp8_idct_add_neon · 49f9c427
      Martin Storsjö authored
      
      
      The original arm version didn't do saturation here. This probably
      doesn't make any difference for performance, but reduces the
      differences.

      Martin Storsjö authored
      
      
      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 clang · 26d7af4c
      Martin Storsjö authored
      
      
      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.

      srt: Set srto_sender flag to sender srt socket · 90b15f60
      Sven Dueking authored
      SRT API Documentation:
      This flag is superfluous if both parties are at least version 1.3.0
      (this shall be enforced by setting this value to SRTO_MINVERSION if
      you expect that it be true) and therefore support HSv5 handshake,
      where the SRT extended handshake is done with the overall handshake
      process.
      
      This flag is however obligatory if at least one party may be using
      SRT below version 1.3.0 and does not support HSv5.

      libopenh264dec: Use a newer decoding entry point function · eec93e57
      Martin Storsjö authored
      
      
      The "new" entry point actually has existed since OpenH264 1.4 in
      2015 and is the the recommended decoding entry point.
      
      The name of this function, DecodeFrameNoDelay, is rather backwards
      considering that it doesn't return the latest decoded frame immediately,
      but actually does proper delaying and reordering of frames.
