[Cin] Vulkan hevc hdr decode regression on ffmpeg master?

Sun May 18 01:56:36 CEST 2025

Checked into GIT the updated ffmpeg.git.patches for future potential
upgrade to ffmpeg version 8.0.  And deleted ffmpeg.git.patch8 after
attempting to determine what it was actually for and could find no
information on that when included sometime in 2019 as patch7.  It is
possible that it is no longer needed though - it may have been intended as
a speed improvement; but if some relevant error resurfaces, it can then be
revisited.

Andrea, the failure in your last attached cin5.log as shown below appears
to be due to commenting out libpostproc.a in configure.ac because that is
needed by cinelerra-5.1/mpeg2enc build.
