Hello,

anything here doesn't conform to the normal mailing list conventions.
I have encountered a problem with ffmpeg (a segmentation fault) that

In a multilib toolchain dlltool has to be configured with the correct
architecture options.
This option allows configuring dlltool this way:
--dlltool="x86_64-w64-mingw32-dlltool --as-flags=--32 -m i386"

Dav1dPictures contain more than one buffer reference, so we're forced to use the
API properly to free them all.

9-14 bit funcs get about 6x speedup, 16-bit gets about 15x.
Fate passes, each format tested with an image to video conversion.
Only POWER8 includes 32-bit

was added in 3.9.
