Is the problem fixed after Reimar's latest commit SVN r38449 ( configure: Fixes for latest FFmpeg )?

[bug]

Works for MinGW32...
...MinGW64: issues with ff_iamf are fixed but those with ff_h2656 persist.

[beastd]

Sorry for the long delay.

Unfortunately I can't reproduce the problem.

Probably some build systems related thing, but I don't understand why it only happens in some environments / configurations.
