• libopenh264dec : Use a newer decoding entry point function

  libopenh264dec: Use a newer decoding entry point function
  
  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.

  avcodec/libdav1d: properly free all output picture references
  
  Dav1dPictures contain more than one buffer reference, so we're forced to use the
  API properly to free them all.

• arm : Create proper .rdata sections for COFF

  11 janvier 2019, par Martin Storsjö

  arm: Create proper .rdata sections for COFF
  
  As .rodata isn't one of the default created sections for COFF, it was
  created as a read-write data section. By using the default .rdata
  section name for COFF, it automatically becomes a read-only data section.
  The existing ".section .rodata" works as intended for ELF though.
  
  This is based on an original patch and diagnose by Tom Tan
  <Tom.Tan@microsoft.com>.
