  avfilter/af_afade: support multiple inputs
  
  Instead of just 2 files, generalize this filter to support crossfading
  arbitrarily many files. This makes the filter essentially operate similar
  to the `concat` filter, chaining multiple files one after another.
  
  Aside from just adding more input pads, this requires rewriting the
  activate function. Instead of a finite state machine, we keep track of the
  currently active input index; and advance it only once the current input is
  fully exhausted.
  
  This results in arguably simpler logic overall.

• swscale : Don't pass a concrete SwsOpPriv as parameter

  swscale: Don't pass a concrete SwsOpPriv as parameter
  
  This fixes the following compiler error, if compiling with MSVC
  for ARM (32 bit):
  
      src/libswscale/ops_chain.c(48): error C2719: 'priv': formal parameter with requested alignment of 16 won't be aligned
  
  This change shouldn't affect the performance of this operation
  (which in itself probably isn't relevant); instead of copying the
  contents of the SwsOpPriv struct from the stack as parameter,
  it gets copied straight from the caller function's stack frame
  instead.
  
  Separately from this issue, MSVC 17.8 and 17.9 end up in an
  internal compiler error when compiling libswscale/ops.c, but
  older and newer versions do compile it successfully.

  avformat/whip: add PRIORITY and ICE_CONTROLLING for STUN binding request
  
  fix issue #20402
  
  See RFC 8445 7.1,
  The PRIORITY and ICE-CONTROLLED or ICE-CONTROLLING must be included
  in a Binding request.
  
  FFmpeg is always ICE Controlling role so we use ICE-CONTROLLING attr.

  avcodec/pcm_tablegen: Fix CONFIG_HARDCODED_TABLES
  
  Broken in ae448e00afb43d7f72dfa9c82a4c45994e4fea6a.
  Notice that config_components.h is safe to include,
  as it is valid for both the host and the target
  (in contrast to config.h).
