Hi,
I ran into a massive memory leak while transcoding some audio
books after upgrading to ffmpeg 6.1.1 from 6.0.1.
Instead of the normal ~100 MiB rss it now exceeds 10 GiB in about
ten seconds and keeps on going up.
Command line used was approximately this:
ffmpeg -activation_bytes XXX -i book.

Adds hwcontext_amf, which allows to use shared AMF
context for the encoder, decoder and AMF-based filters,
without copy to the host memory.
It will also allow you to use some optimizations in
the interaction of components (for example, SAV) and make a more
manageable and optimal setup for using GPU

This commit adds two AMF filters: vpp_amf & sr_amf.
Both filters are using AMF hardware acceleration.
vpp_amf supports simple scaling algorithms & color conversion.
sr_amf supports advanced scaling algorithms such as FSR & can
be used for upscaling only.

When I attempt to pass vbv-end and vbv-end-fr-adj parameters to x265, FFMPEG
fails.
x265 [error]: vbv-end-fr-adj cannot be enabled when total number of frames is

vbv-end logic needs to kick in. In this case it
