Description

Any ffmpeg configuration that enables the atempo filter but doesn't enable rdft will fail to compile with the following errors:

The solution would be to either make the atempo filter depend on rdft or to force the later's compilation.
Either making

atempo_filter_deps="avcodec"

be

atempo_filter_deps="avcodec rdft"

or by adding a new line like

atempo_filter_select="rdft"


Considering that none of the other filters force the compilation of any other component, maybe the former is the better option.
